The liver is the most frequently injured organ during abdominal trauma. Vascular injuries account for approximately 3% to 25% of all cases of liver trauma and are typically treated by transarterial embolization (TAE). We describe a case of American Association for the Surgery of Trauma grade V liver injury with a very large pseudoaneurysm and an arteriohepatic venous fistula (AHVF), which failed to respond to TAE. This case was successfully treated using a direct transhepatic glue injection without complications. AHVF is an exceedingly rare type of vascular injury in blunt trauma. Direct transhepatic glue injections could represent a reliable alternative to TAE for the treatment of visceral pseudoaneurysms, especially if TAE fails to eliminate the lesion.

A cardiac outpouching (CO) is a protrusion in a heart chamber’s internal anatomical lining. Most COs are clinically insignificant, but some are of vital importance, requiring immediate surgery. Cross-sectional imaging findings of COs, such as location, morphology, size, and accompanying wall motion abnormalities, play an esŞential role in determining the correct diagnosis and appropriate clinical management. Therefore, radiologists should be familiar with them. This article reviews the key cross-sectional imaging findings and differential diagnoses of COs. © 2023, Turkish Society of Radiology.

Transcatheter arterial embolization is a safe and effective treatment for visceral artery aneurysms; nevertheless, some complications can occur. Coil migration to other organs after embolization is extremely rare, and only 16 cases have been reported previously. We report a rare case of coil migration to the duodenal lumen after embolization of a right colic artery pseudoaneurysm. To the best of our knowledge, this is the first case of coil migration after a right colic artery embolization. The patient exhibited no symptoms and was treated conservatively without any intervention. Some previous reports have demonstrated spontaneous coil passage and successful conservative management. Our case supports conservative treatment as the primary treatment for asymptomatic patients. Clinicians should assess the risks and benefits of coil removal in asymptomatic patients before performing any intervention.

We present an endovascular approach for anatomic reconstruction of the iliac bifurcation in life-threatening arterioureteral fistula without sacrificing the pelvic arterial vascular supply. Five consecutive patients suffering from acute onset of significant gross hematuria caused by iliac-ureteral fistula resulting from previous oncologic surgery and radiation therapy were treated by transfemoral stent graft implantation in a double-barrel technique. Iliac-ureteral pseudoaneurysm coverage succeeded in an iliac neobifurcation with preservation of pelvic perfusion. Follow-up ranging from 9 to 37 months confirmed cessation of hematuria. One patient experienced stent graft thrombosis of the external iliac artery as a result of large cervical cancer invasion treated by crossover bypass. In all other patients, stent grafts were patent.

Subclavian artery injuries after central venous catheter placement constitute a rare but potentially fatal complication. The surgical repair of a subclavian artery trauma is a real challenge, associated with a high rate of morbidity and mortality. The role of endovascular treatment for vascular trauma, including injury to the subclavian artery, continues to evolve. In this manuscript, we report the case of an urgent endovascular repair by a covered stent graft of a subclavian artery perforation following the placement of a central venous catheter for dialysis in a 52-year-old patient, having a chronic kidney failure stage 5, with multiple comorbidities. The present case suggests that attention needs to be paid to preventing iatrogenic arterial cannulation during central vein catheterization to avoid potentially devastating complications. Endovascular treatment using a covered stent should be attempted as a first-line therapeutic option.

Pulmonary artery pseudoaneurysms (PAPs) are rare serious vascular abnormalities mostly due to infections and trauma, although other conditions such as vasculitis, neoplasms, or inflammatory lung diseases can also predispose to this entity. Endovascular techniques such as embolization or covered stent placement have mostly substituted surgical approaches, for their lower invasiveness and greater security, mainly in patients with life-threatening hemoptysis. The purpose of this manuscript is to describe the imaging findings of pulmonary artery pseudoaneurysms and their endovascular management including tips to help interventional radiologists. PAP should be diagnosed as accurately and early as possible in order to prompt endovascular management of further life-threatening hemoptysis. • Pulmonary artery pseudoaneurysms (PAPs) are rare serious vascular abnormalities that may represent a life-threatening condition, mainly due to Staphylococcus, Streptococcus, or Mycobacterium tuberculosis. • Radiologists should know the imaging findings of PAP in order to make an accurate and early diagnosis to prompt endovascular management of further life-threatening hemoptysis.

Pseudoaneurysm is a rare vascular complication of trauma, causing an incomplete tear of the vessel wall. We present a clinical case report arising from the distal branch of facial artery in an infant. Facial artery pseudoaneurysm is a rare complication of facial trauma and can easily be misdiagnosed especially in the paediatric age group. Prompt investigation and diagnosis with timely and apt intervention is the key to the successful management of facial artery pseudoaneurysm.

Blunt thoracic aortic injuries are potentially lethal. Those who survive may form an organised haematoma in the periadventitial space resulting in a pseudoaneurysm, which may be identified incidentally decades later. While the role of thoracic endovascular aortic repair (TEVAR) in acute settings has been established, its role in chronic cases is yet to be defined. We report three cases that were diagnosed incidentally six, nine and 18 years after the injury. Two were managed by TEVAR while the third declined intervention and is on annual follow-up. Patients with asymptomatic and stable pseudoaneurysms of the descending thoracic aorta should be offered surveillance versus TEVAR because the risk of rupture is not negligible, whilst taking into account the patient’s level of physical activity. These three cases highlight the importance of early diagnosis of aortic injuries in blunt trauma and its grading.

BACKGROUND Coronary angiography and intervention through transradial approach is becoming default approach because of infrequent local site complications. Although pseudoaneurysm is a well described complication for femoral access, it is extremely rare in transradial access. CASE REPORT Our patient was 68-year old female who had presented with pulsatile, painful, and gradually increasing swelling over lower part of right forearm near wrist joint for past 8-weeks following coronary angiography through right radial route. Swelling did not resolve following manual compression. It was diagnosed as pseudoaneurysm arising from right radial artery by duplex ultrasound. It was successfully excluded by deploying 3.5x18mm Graftmaster covered stent (Abott Vascular, USA) through right transbrachial route. Ultrasonography next day revealed partially thrombosed and completely excluded pseudoaneurysm with swelling completely disappearing at 6 weeks with patency maintained at one year. CONCLUSION With increasing use of transradial access, more cases of radial pseudoaneurysm are likely to surface which can be prevented following a proper haemostatic protocol. To best of our knowledge, it is first ever report of percutaneous endovascular exclusion using covered stent of radial pseudoaneurysm through transbrachial approach.

A feared complication of acute myocardial infarction is the formation of a cardiac pseudoaneurysm. We report a case of a gargantuan, arrhythmogenic left-ventricular pseudoaneurysm with contradictory morphological characteristics. The integrative use of high-resolution 3-dimensional magnetic resonance imaging and computed tomography proved essential for the diagnostic discrimination and successful therapeutic intervention.

A case of endovascular treatment of a patient with a large false aneurysm of the splenic artery resulting from arrosion of its wall into the cavity of a previously existing pancreatic pseudocyst is described. In addition to the rather rare occurrence of this pathology, a feature of this clinical case was the patient’s sharp tortuosity of the access vessels, including the iliac arteries, abdominal aorta, and the splenic artery. Thus, both the endovascular prosthetics of the affected splenic artery and its embolization according to the traditional method using standard angiographic catheters and Gianturco coils turned out to be technically impossible because of the inability to reach the lesion site, especially with access through the common femoral artery that typical for such interventions, which was used by us when performing diagnostic selective arteriography. The second stage was the embolization of the splenic artery by access through the left axillary artery by means of conducting of guiding catheter into the celiac trunk. Through the lumen of this catheter, we introduced a microcatheter, through which detachable microcoils (usually used in interventional neuroradiology) were introduced into the splenic artery proximal and distal to the aneurysm cavity. As a result, the affected area of ​​the splenic artery with aneurysm was completely turned off from the bloodstream and thrombosed, that allowed to avoid extremely risky open surgical intervention and eliminated the risk of rupture of the aneurysm. Medication support included hypotensive therapy to reduce the risk of rupture of the aneurysm (before and after surgery), analgesics for the relief of post-embolization pain, and antibiotics for the prevention of infectious complications associated with pancreatitis and the possible development of spleen infarction. Monitoring the effectiveness of the intervention in the postoperative period was carried out using ultrasound dopplerography.

Purpose The frequency of iatrogenic femoral artery pseudoaneurysm (FAP) diagnoses has recently increased due to the growing use of diagnostic and interventional procedures involving large diameter sheaths, as well as more potent anticoagulation procedures. In this study, we aimed to present our experience with ultrasound-guided thrombin injection (UGTI) in patients with iatrogenic FAP. Methods We studied patients with FAP who were under anticoagulant or antiplatelet therapies preoperatively, or who had received a loading dose during an interventional procedure. The outcomes of patients with FAP treated with UGTI were compared with those of patients who underwent open surgical repair for pseudoaneurysms. Results Among the 55 patients included in this study, 24 had UGTI while 31 had open surgery. The success rate was 95.8% when taking into consideration primary and secondary attempts. The mean duration of the procedure was shorter in patients with UGTI (10.1 ± 3.54 minutes) when compared with those who underwent open surgery (76.55 ± 26.74 minutes, P ≤ 0.001). In addition, the total complication frequency was significantly higher in the open surgery group (P = 0.005), as was their length of hospital stay (P < 0.001). Cost analysis showed significant differences between UGTI ($227.50 ± $82.90) and open surgery ($471.20 ± $437.60, P = 0.01). Conclusion We have found that UGTI is the safer and more effective choice of treatment in appropriate patients with FAP, as opposed to surgery.

BackgroundPost-infarction left ventricular (LV) pseudoaneurysm is a rare mechanical complication of myocardial infarction that carries a substantial risk of sudden rupture. The purpose of this study was to compare the surgical results of post-infarction LV pseudoaneurysm with those of conservative treatment.MethodsFrom 2016 to 2021, 22 patients were hospitalized for LV pseudoaneurysm, including 17 cases (77.3%) caused by myocardial infarction. Of the 17 patients, 10 (58.8%) underwent surgical repair, while seven (41.2%) were treated medically. The clinical course, echocardiograph data, and surgical outcomes were analyzed. Survival rates of the surgical and conservative groups were compared.ResultsThere were no perioperative deaths. Intra-aortic balloon pumping support was required in two (20%) patients. No follow-up mortality was observed in the surgical group and at the last follow-up, all the patients were classified as New York Heart Association class I–II. In the conservative group, there was one (14.3%) hospital death and two (28.6%) additional deaths during follow-up. A significant difference was found in survival between the two groups (P = 0.024).ConclusionsSurgical repair of post-infarction LV pseudoaneurysm can be performed with good results, while conservative treatment carries a significant risk of sudden death. Surgical repair is indicated for every patient diagnosed, even those with a small pseudoaneurysm without symptoms.

RESUMEN Los pseudoaneurismas de la arteria humeral son infrecuentes, pero pueden asociarse a complicaciones de alta morbilidad como la isquemia de miembro superior. Comunicamos un caso de pseudoaneurisma humeral en el pliegue del codo, que se presentó como tumor pulsátil con leve disminución de la temperatura y parestesias en la mano homolateral de un año de evolución, debido a una punción arterial inadvertida durante la venopunción para extracción de sangre. Se trató con éxito mediante resección quirúrgica más reconstrucción vascular con bypass húmero-cubital y bypass húmero-radial ambos con vena safena. Se discuten las diversas opciones terapéuticas disponibles para los pseudoaneurismas humerales considerando las características anatómicas y la sintomatología del paciente. ABSTRACT Brachial artery pseudoaneurysms are rare but can be associated with severe complications as ischemia of the upper extremity. We report a case of a brachial artery pseudoaneurysm in the crease of the elbow presenting as a pulsating mass with progressive growth over the past year. The ipsilateral hand was sightly cold and presented paresthesia. The lesion was due to inadvertent arterial puncture during venipuncture. The pseudoaneurysm was successfully treated with surgical resection and vascular reconstruction with a brachial to ulnar artery bypass and brachial to radial artery bypass with saphenous vein graft. The different therapeutic options available for brachial artery pseudoaneurysms are discussed, considering the anatomic characteristics and patients’ symptoms.

Highlights • Pseudoaneurysm of the superolateral genicular artery is a risk in arthroscopic knee procedure. • Pseudoaneurysms risk increase due to minimal invasive procedure. • Ultrasound-guided percutaneous thrombin injection for iatrogenic pseudoaneurysms is a valuable option., Introduction Arthroscopic procedures are a safe way nowadays to do anterior cruciate ligament reconstruction. Rare complications involve injuries to popliteal vessels or one of its branches. Presentation of case We present a case of a young patient who undergone an anterior cruciate ligament reconstruction. This procedure was associated with a meniscal suture. The follow-up was marked by pseudoaneurysm of the supero-lateral genicular artery. Discussion This is the first time a pseudoaneurysm of this branch is described in the literature as we discovered it. The treatment by an ultrasonography-guided embolization with thrombin was proceeded and suceeded. Conclusion We stress the fact with new arthroscopic procedures and techniques, new complications can occur, and we should be attentive to them and new symptoms consequently, as a painless mass on the lateral side of the knee, to ensure a fast and optimal treatment.

Behçet's disease (BD) is a multisystemic, chronic autoimmune inflammatory vasculitic disease with an unknown etiology. Although the literature reports that vascular involvement occurs in 7% to 38% of all BD cases, the arteries are rarely involved; however, arterial involvement is usually associated with significant mortality and morbidity. We report the case of a young female patient who presented to the emergency department with severe abdominal pain and a history of weight loss. The patient was evaluated using computed tomography angiography, which revealed a ruptured suprarenal aortic pseudoaneurysm with occlusion of both the superior mesenteric and celiac arteries. Urgent surgery was performed with aortic repair with an interposition graft and superior mesenteric artery embolectomy. The patient's clinical history and radiological imaging findings were strongly suggestive of the diagnosis of BD with vascular involvement.

Pseudoaneurysm formation in the profunda femoris artery (PFA) is a rare complication of femur shaft fractures or, more usually, a consequence of operative repair. Over the past few years, percutaneous transcatheter arterial embolization (TAE) has increasingly been considered the most effective treatment for pseudoaneurysms of the PFA. We report two cases with pseudoaneurysms of the PFA that were caused by femur shaft fractures and were successfully treated using TAE with n-butyl cyanoacrylate (NBCA). When a pseudoaneurysm of the PFA occurs due to a femur shaft fracture, early recognition and prompt radiologic intervention may prevent severe vascular injury without the need for additional surgery. The advent of TAE using NBCA enables minimally invasive treatment to be undertaken and it is effective for managing pseudoaneurysms of the PFA.

Dorsalis pedis artery (DPA) aneurysms are very rare and fewer than 60 cases have been reported in the literature. Most affected patients present with false aneurysms after orthopedic surgery or trauma. Here we report an unusual case of a giant DPA pseudoaneurysm after cannulation for arterial line placement in a patient newly diagnosed with systemic lupus erythematosus (SLE). A diagnostic delay resulted in necrosis of the overlying skin. Excision of the pseudoaneurysm, ligation of the DPA, and debridement of the foot dorsum were performed, followed by a second flap coverage surgery. Although a DPA false aneurysm is rare after arterial line removal, it can cause the serious complications of skin necrosis, rupture and toe necrosis. Arterial puncture sites should be carefully monitored, especially in patients with SLE or other vasculitis.

The article describes the clinical experience of treatment of life-threatening pathology by minimally invasive methods. There is a long-term stable positive result after the operation. The introduction of new technologies in medicine minimizes the risk of postoperative complications, contributing to a favorable outcome of the disease.

Contemporary management of iatrogenic pseudoaneurysms is mostly performed using non-surgical techniques. Herein, we present a rare case of deep femoral artery (DFA) pseudoaneurysm with compression neuropathy, which required open repair. A 67-year-old female patient presented with increasing pain in the right groin, sensory neuropathy of the anteromedial thigh and upper leg, and quadriceps paralysis 4 days after coronary angiography via femoral puncture. Computed tomography angiography revealed a pseudoaneurysm of the DFA. The disabling compressive neuropathy warranted urgent open decompression rather than thrombin injection or endovascular therapy. Timely open evacuation of the hematoma, release of compression on the femoral nerve, and postoperative physiotherapy resulted in complete recovery of quadriceps power. The patient was pain free within 12 weeks and able to ambulate independently. This case report highlights the role of prompt open surgery for pseudoaneurysms with compression neuropathy.

Non-traumatic, simultaneous pseudoaneurysms of the bilateral superficial femoral arteries (SFAs) are extremely rare. Spontaneous transection of the SFA is another unique pathology. Here, we present a patient with end stage kidney disease who was diagnosed with bilateral, simultaneous SFA pseudoaneurysms. He had a recent history of methicillin-sensitive Staphylococcus aureus septicemia; therefore, infection was suspected to be the main cause. Complete transection of the SFA was noted during the operative exploration of the symptomatic left side. Wide debridement and autologous vein bypass were performed via a clean route. Unfortunately, two months later, recurrent surgical site infection caused distal anastomotic rupture and fatal sepsis.

Carotid endarterectomy (CEA) with patch angioplasty is a widely used method for treating carotid artery stenosis. Patch infections are extremely rare, but the consequences may be serious. The current gold standard for treatment is patch excision and reconstruction with autologous material. However, no consensus has been reached and other options may be valuable as well in certain cases. The objective of this study was to evaluate the various treatment options for carotid patch infection after CEA with patch angioplasty on the basis of their outcomes (reinfection, ischemic stroke, and infection-related mortality). This systematic review was conducted in accordance with the PRISMA statement. The electronic bibliographic databases PubMed, Cochrane, and EMBASE were searched. Case series and case reports were included. Studies in languages other than English were excluded. Patients who developed a post-operative patch infection of CEA with patch angioplasty were included. Angioplasty could be performed with any type of patch. Patch infection needed to be confirmed by clinical presentation in combination with imaging, culture, or during the operation. The primary outcome measures were reinfection, ischemic stroke, and infection-related mortality. Eleven retrospective case series, two prospective case series, and seventeen case reports were included. The study size was 165 patients (mean age 69.7 years, M/F ratio 1.75:1). One hundred and seventy-one patches developed a patch infection after CEA with patch angioplasty and needed treatment. Treatment strategies included conservative treatment (14.0%), endovascular treatment (4.7%), and open surgery (81.4%). Mean follow-up was 34.8 months and extended up to 180 months. Reinfection rate was 4.7%, ischemic stroke rate 5.8%, and infection-related mortality rate 2.3%. No statistical comparison between treatment options could be performed, because of the heterogeneity of the included studies. Autologous material should be the primary choice of treatment if patch infection is diagnosed after CEA with patch angioplasty. In emergency situations, endovascular treatment, carotid ligation, or abscess drainage could be considered. Endovascular treatment and abscess drainage are temporary solutions. After the patient has recovered sufficiently, a more durable treatment i.e., open surgery is advised. Endo vacuum assisted closure (EndoVAC) seems to be promising. Further research is needed to determine the applicability of each treatment option.

Le pseudo anevrysme de l´arcade palmaire superficielle est une entite rare et seuls quelques cas ont ete decrits dans la litterature. La majorite se developpe apres une lesion de l´artere suite a un traumatisme penetrant, a une intervention chirurgicale anterieure ou a une ponction arterielle. Le diagnostic repose sur une suspicion clinique elevee, notamment en presence d´une masse pulsatile. Ci-dessous, nous presentons le cas d´un faux anevrisme de l´arcade palmaire superficielle chez un enfant de 3 ans a la suite d´une blessure par du verre brise.

Visceral artery aneurysms, which could be either true or pseudo, are abnormal focal dilations of vessels supplying the abdominal organs. True aneurysms, by definition, suggest dilation of the vessel in response to increased blood flow, ultimately causing a blood-filled sac to form. Pseudoaneurysm, however, is the pooling of blood in surrounding tissues secondary to trauma or rupture. A 43-year-old woman G9 P9, known hypertensive was admitted electively for investigation of melena, hematemesis, hematochezia for one week along with weight loss and epigastric pain. Laboratory studies showed mild anemia with a hemoglobin level of 9.6 g/dL, hematocrit 29.5%, mean corpuscular hemoglobin (MCH) 26.7, upon which she was transfused two pints of blood and commenced at Injectable Vitamin K, injectable transamine, and infusion omeprazole. Two days later her levels improved to HB 12.4 g/dL, hematocrit 37.5%, MCH 26.7 pg, RBC 4.64 × 10*12/L. while being on treatment, a computed tomography (CT) mesenteric angiography was also conducted that showed multiple splanchnic pseudoaneurysms involving celiac axis trifurcation, gastroduodenal artery, superior/inferior pancreaticoduodenal artery, and jejunoileal branch of the superior mesenteric artery, and a large partially thrombosed pseudoaneurysm arising from superior pancreaticoduodenal branch causing significant mass effect on the second part of duodenum. On the basis of such findings, it was advised to perform coiling and embolization of the corresponding arteries. Multiple other small aneurysms with secondary arteriovenous malformations (AVM) were also seen. The whole circuit of flow retrograde and antegrade along with the aneurysm sac was blocked with multiple coils of variable sizes. An angiogram was repeated that revealed a good outcome. Pseudoaneurysms of the visceral arteries are very rare and affect mainly the splenic artery. The rarest of which is gastroduodenal artery (1.5%), pancreaticoduodenal artery (2%), and coeliac truck (4%). Therefore, this can be an incidental finding. The diagnosis is usually made with an angiography combined with clinical presentation. Variable treatment options are available depending on the patient’s fitness and hemodynamic stability. The endovascular approach, however, is mostly used in such cases.

Background The formation of a uterine artery pseudoaneurysm is rare and isolated cases have been reported in the existing literature following caesarean sections, curettages and cone biopsies. There has been no report of pseudoaneurysm formation following a loop electrosurgical excision procedure. Vaginal bleeding could potentially be life threatening if this diagnosis is not considered following cervical instrumentation or surgery. Management options range from haemostatic sutures, image-guided embolisation to surgical repair. We report the diagnosis and management of a case of uterine artery pseudoaneurysm after a loop electrosurgical excision procedure. Case presentation A 37-year-old woman was diagnosed with cervical intraepithelial neoplasia grade 3 (CIN3) and underwent a therapeutic loop electrosurgical excision procedure. One month after the procedure, the patient presented to the emergency department with repeated episodes of sudden-onset heavy vaginal bleeding associated with hypotension and syncope. A computed tomography angiogram was performed, which demonstrated a pseudoaneurysm of the right uterine artery. Following the diagnosis, image-guided embolisation was performed successfully. Post-embolisation angiograms showed successful embolisation of the pseudoaneurysm and the patient had no further episodes of bleeding. Conclusions Loop electrosurgical excision procedures are generally safe but rarely, can be complicated by the formation of uterine artery pseudoaneurysms. The depth of the loop electrosurgical excision procedure and vascular anatomy should be considered to prevent such complications. A computed tomography angiogram appears to be ideal for diagnosis. Image-guided embolisation is safe and effective as a therapeutic measure, with minimal morbidity.

Blunt perineum trauma rarely leads to massive urethrorrhagia due to the formation of a bulbar aneurysm. A 29-year-old man with unstable hemodynamic underwent a digital subtraction angiography (DSA), which revealed a pseudoaneurysm in the penile bulb supplied from both internal pudendal arteries fistulized to the urethral duct bulb. A catheter was inserted into the distal part of pudendal arteries at the pseudoaneurysm's proximity, and an intermittent embolizing agent (Gel-foam) was injected. The pseudoaneurysm was filled with Gel-foam. Despite the superiority of conservative management, urethrorrhagia's life-threatening nature calls for angiographic intervention, successfully embolized using gel-foam with negligible complications.

This is the case of a 46-year-old man, asymptomatic, with a history of single-disk mechanical aortic prosthesis implanted 25 years ago, who was incidentally diagnosed with a pseudoaneurysm of the mitral-aortic intervalvular fibrosa (a region of fibrous tissue located between the anterior leaflet of the mitral valve and the left and non-coronary aortic leaflets) discovered by means of a transthoracic echocardiography, transesophageal echocardiography and cardiac computed tomography. Surgery was decided because of the size of the pseudoaneurysm. This article shows the late presentation of a pseudoaneurysm in this location caused by a complication of an aortic valve replacement due to endocarditis. It also highlights the asymptomatic evolution, the size of the pseudoaneurysm and the election of a valve preserving surgery because the valve was not compromised. The different imaging techniques are complementary to the research and help to make the pertinent decisions. Se presenta el caso de un varón de 46 años, asintomático y con antecedente de prótesis mecánica aórtica monodisco desde hace 25 años. Mediante el empleo de la ecocardiografía transtorácica, ecocardiografía transesofágica y tomografía cardiaca, se le diagnostica, incidentalmente, un seudoaneurisma de la fibrosa intervalvular mitroaórtica (región de tejido fibroso localizada entre el velo anterior de la válvula mitral y los velos aórticos izquierdo y no coronariano). Debido al tamaño del pseudoaneurisma, se decide realizar una cirugía. Este artículo muestra la presentación tardía de un pseudoaneurisma en esta localización que aparece como una complicación del reemplazo de la válvula aórtica por endocarditis. Se destaca la evolución asintomática, el tamaño y la cirugía que preserve la válvula cuando no está comprometida. Las diferentes técnicas de imagen son complementarias y ayudan en tomar las decisiones del caso.

Vascular injuries following anterior shoulder dislocations are rare, with an estimated incidence of 1-2%. The formation of an axillary artery pseudoaneurysm secondary to vascular trauma is a possible late complication and frequently underdiagnosed since it may remain asymptomatic for many years. A rupture of a pseudoaneurysm may occur either from the dislocation itself or after forceful reduction attempts. A ruptured pseudoaneurysm of the axillary artery is a medical emergency and may result in significative upper-limb morbidity or even patient mortality. Nowadays, endovascular techniques have progressively gained ground for the treatment of such lesion, especially in an emergency context. In the present article, the authors present the case of a 77-years-old male patient with a rupture of a pseudoaneurysm of the left axillary artery after repeated forceful reductions of an anterior glenohumeral dislocation and its treatment with percutaneous endovascular stenting.

Free wall rupture after a myocardial infarction may rarely cause a left ventricular (LV) pseudoaneurysm to develop. LV pseudoaneurysms are most commonly discovered incidentally on echocardiography and require a high index of suspicion to diagnose. We report the case of a 73-year-old male who experienced an asymptomatic myocardial infarction leading to cardiac arrest after placement in the Trendelenburg position. During resuscitation efforts, he was discovered to have an LV pseudoaneurysm on transthoracic echocardiogram. We report an unusual presentation of LV pseudoaneurysm and discuss a possible link between Trendelenburg position and the development of LV pseudoaneurysm.

Introduction Pseudoaneurysms of the renal artery are fairly uncommon and mostly asymptomatic. They develop mostly in the right renal artery and in female patients. Report In this report, a female patient with an intraparenchymal renal artery pseudoaneurysm with one year follow up is described. She presented with non-specific abdominal pain. A computed tomography scan revealed hydronephrosis of the right kidney and a giant, intracapsular, contained rupture of a pseudoaneurysm of the right renal artery. The patient was admitted to hospital and underwent a successful selective embolisation of the pseudoaneurysm. Follow up at one year showed normal renal function and an excluded aneurysm. Discussion Although relatively uncommon, renal artery pseudoaneurysms should be considered in the work up of patients with colicky flank pain. As a treatment option, endovascular approaches are appealing because they are less invasive. Successful treatment can prevent resection of the affected kidney., Highlights • This report describes the rare case of a young female patient with contained rupture of a right renal artery pseudoaneurysm. • The pseudoaneurysm was treated by endovascular coiling, preserving the kidney and its function. • A spontaneous pseudoaneurysm is a rare cause of colicky flank pain. • Endovascular treatment is a good treatment option. • Most pseudoaneurysms present after direct penetrating injury and not spontaneously.

Summary: Successful step-by-step treatment of a combined gunshot shrapnel injury of the brain, damaging the left middle cerebral artery (MCA) branches, and penetrating myocardium injury is discussed. Open brain and heart surgeries were performed. A left MCA pseudoaneurysm was formed postoperatively. Endovascular exclusion of the left MCA pseudoaneurysm was performed using detachable micro coils. Finally, plastic reconstruction of the posttraumatic cranial vault defect was performed using a dynamic titanium plate.Treatment of severe combined gunshot shrapnel brain injury with formation of MCA pseudoaneurysm and a penetrating myocardium injury requires a multimodal approach involving related specialists (neurosurgeon, cardiosurgeon and interventional radiologist).

We describe a patient in whom a stab wound to the right supraclavicular fossa led to a subclavian artery false aneurysm and an arterio-venous fistula (AVF) between the right subclavian artery and the right internal jugular vein. The diagnosis was made clinically and with computerised tomographic angiography (CTA). Open vascular repair was successful. We postulate that this presentation was the result of the knife being inserted then partly withdrawn and reinserted at a different angle. This pattern of injury has been reported previously following central venous line insertion, but rarely following a stab injury.

Pseudoaneurysm is a well-recognised form of vascular injury following blunt trauma. Its diagnosis is often delayed due to late manifestation of signs and symptoms. Nonetheless, complications of pseudoaneurysm can be severe and even fatal. A 60-year-old man presented to our tertiary trauma centre with blunt chest trauma. His treatment was initially focused on the left clavicular fracture. He was eventually diagnosed with a dorsal scapular artery pseudoaneurysm and a large chest wall haematoma on computed tomography on his third hospital admission in two weeks. This pseudoaneurysm was treated with endovascular embolisation. This article highlights the value of meticulous clinical examination as well as judicious use of biochemistry and imaging in trauma management.

Vascular injuries following intertrochanteric fracture have been sporadically reported. Despite its rare occurrence, this complication can be potentially life and limb threatening. The authors report an unusual presentation of false aneurysm of profunda femoris artery following an intertrochanteric fracture with marked displacement of lesser trochanter fragment. The patient presented with thigh swelling and unexplainable dropped hematocrit. Surgical exploration and vascular repair were done. It is essential for the surgeon to be aware of possible associated vascular injuries in intertrochanteric fracture, particularly in fracture with lesser trochanter fragment.

Nolwenn Riou-Comte,1 Gioia Mione,1 Lisa Humbertjean,1 Marie-Alexia Ottenin,2 Jean-Christophe Lacour,1 Sébastien Richard1,3 1Department of Neurology, Stroke Unit, University Hospital of Nancy, Nancy Cedex, France; 2Department of Neuroradiology, University Hospital of Nancy, Nancy Cedex, France; 3Centre d’Invesigation Clinique Plurithématique Pierre Drouin CIC-P 1433 INSERM U1116, University Hospital of Nancy, Vandoeuvre-lès-Nancy, France Objective: Spontaneous cervical artery dissection (CAD) is a cerebrovascular disease typically considered to affect the young population. Literature reports cases in the elderly only as incidental findings, making the diagnosis unlikely in older patients. Incidence and pathogeny in this specific population remain to be assessed.Methods: We reviewed patients aged over 70 years admitted for spontaneous CAD in the Stroke Unit of the University Hospital of Nancy (northeastern France) over a period of 12 years as well as all reported cases in literature.Results: During this period, only two patients aged over 70 years were diagnosed with internal carotid artery dissection in our center. The first patient was diagnosed with the typical radiological feature of long tapered stenosis due to mural hematoma. The second patient presented with the classic painful Horner syndrome. Literature review identified only two case reports and eight studies with an age range above 70 years. Headache was present in nearly all documented cases. Radiological features were the same as those usually described in younger patients.Conclusions: Even if spontaneous CAD in patients aged over 70 years would appear to be rare, it does occur with comparable clinical and radiological features as in the younger population. CAD is probably underdiagnosed in this population due to a higher prevalence of more common causes of stroke at this age. However, a simple investigation into headache or the Horner syndrome during the patient’s diagnostic workup would lead to adapted exploration of cervical arteries and improve detection of CAD in the elderly.

False Aneurysms are uncommon in the pediatric population. We report a case of false aneurysm of the common femoral artery (CFA) after accidental arterial puncture, during a phlebotomy for blood sample. The lesion was surgically resected and arterial continuity restored by end to end anastomosis. The postoperative course was uneventful.

Purpose: We report the case of a thoracic endograft used to achieve exclusion of a ruptured proximal paranastomotic abdominal aortic aneurysm (PAAA) as a consequence of aortic ballooning. Case Report: A type I proximal endoleak was evidenced following endovascular repair of a PAAA with an aortic cuff. The leak was treated with ballooning, which caused distal aortic rupture. A thoracic endograft was deployed inside the cuff, achieving complete exclusion. At 1 year, there are no signs of migration or endoleak with complete PAAA thrombosis, according to computed tomographic angiography. Conclusion: In hostile proximal abdominal aortic neck, challenging anatomies, or urgent cases, the structural adaptability of thoracic endografts could provide safe and successful abdominal aortic endovascular exclusion.

Ultrasound-guided thrombin injection has been shown to be a safe and effective treatment for iatrogenic post-catheterization pseudoaneurysms, but still is underused in France. We report our single-center experience and propose a technical guideline for ultrasound-guided thrombin injection. Ultrasound-guided thrombin injection should be considered to be the first-line treatment of iatrogenic pseudoaneurysms.

Resumen Los aneurismas pediátricos son raros y pueden se causados por infección al dañar la pared arterial formando una saculación ciega contigua a su lumen denominada pseudoaneurisma micótico. La mayoría de los casos reportados son de pacientes ancianos con comorbilidades y los agentes causantes más frecuentes son Staphylococcus spp, Salmonella spp, Streptococcus spp y raramente hongos. Se presenta el caso de un niño de 3 años con: diagnóstico reciente de leucemia linfoblástica aguda de precursores B en remisión; alto riesgo de recaída por tratamiento incompleto y antecedente de bacteremia por Staphylococcus epidermidis y fungemia por Cándida tropicalis; vegetaciones cardiacas que hacen embolismo a hígado, bazo, pulmón y cerebro, y pseudoaneurisma micótico parcialmente trombosado de la arteria ilíaca común y externa. El diagnóstico temprano de esta entidad es de vital importancia por el riesgo de ruptura y el manejo quirúrgico dependerá de la localización, el tamaño y las complicaciones asociadas. Abstract Pediatric aneurysms are rare and can be caused for damaging of the arterial wall secondary to an infection, forming a blind sacculation contiguous to its lumen called mycotic pseudoaneurysm. The majority of reported cases are from elderly patients with comorbidities. The most frequent involucre microorganisms are Staphylococcus spp, Salmonella spp, Streptococcus spp and rarely fungi. We present the case of a 3-year-old boy, with a recent diagnosis of acute lymphoblastic leukemia of B precursors in remission, with a high risk of relapse due to incomplete treatment and a history of bacteremia due to Staphylococcus epidermidis and fungemia due to Candida tropicalis; with cardiac vegetations that produce liver, spleen, lung and brain embolism, in whom a partially thrombosed mycotic pseudoaneurysm of the common and external iliac artery is found. The early diagnosis of this entity is of vital importance because of the risk of rupture. Surgical management will depend on the location, size and associated complications.

Background We report on an unusual case of a 3 year-old girl with coarctation of the aorta complicated by mycotic pseudoaneurysm and infected with Streptococcus pneumoniae. Case summary The only symptoms and signs were fever and weak femoral pulses. The echocardiography confirmed a localised isthmic's coarctation. In order to complete the evaluation, a CT scan was performed. This proved crucial in terms of the diagnosis and decision to perform emergency surgery. The diagnosis was confirmed surgically. An aortic rupture was contained by the parietal pleura. Bacteriological analysis of surgical specimens revealed bacterial DNA that tested positive for Streptococcus pneumoniae. The post-operative course was free from any cardiovascular or neurological complications after six weeks of antibiotic therapy. Discussion Surgical repair of coarctation of the aorta is frequently performed in children. However, complicated forms are less common with a potentially fatal outcome. Indeed, there are no recommendations concerning the management and surgical timing of mycotic pseudoaneurysm. These rare complications should be kept in mind. Although short- and medium-term follow-up of these children is good, caution should be exercised with long-term follow-up because of complications in childhood and adulthood.

Carotid endarterectomy (CEA) with patch angioplasty is a widely used method for treating carotid artery stenosis. Patch infections are extremely rare, but the consequences may be serious. The current gold standard for treatment is patch excision and reconstruction with autologous material. However, no consensus has been reached and other options may be valuable as well in certain cases. The objective of this study was to evaluate the various treatment options for carotid patch infection after CEA with patch angioplasty on the basis of their outcomes (reinfection, ischemic stroke, and infection-related mortality). This systematic review was conducted in accordance with the PRISMA statement. The electronic bibliographic databases PubMed, Cochrane, and EMBASE were searched. Case series and case reports were included. Studies in languages other than English were excluded. Patients who developed a post-operative patch infection of CEA with patch angioplasty were included. Angioplasty could be performed with any type of patch. Patch infection needed to be confirmed by clinical presentation in combination with imaging, culture, or during the operation. The primary outcome measures were reinfection, ischemic stroke, and infection-related mortality. Eleven retrospective case series, two prospective case series, and seventeen case reports were included. The study size was 165 patients (mean age 69.7 years, M/F ratio 1.75:1). One hundred and seventy-one patches developed a patch infection after CEA with patch angioplasty and needed treatment. Treatment strategies included conservative treatment (14.0%), endovascular treatment (4.7%), and open surgery (81.4%). Mean follow-up was 34.8 months and extended up to 180 months. Reinfection rate was 4.7%, ischemic stroke rate 5.8%, and infection-related mortality rate 2.3%. No statistical comparison between treatment options could be performed, because of the heterogeneity of the included studies. Autologous material should be the primary choice of treatment if patch infection is diagnosed after CEA with patch angioplasty. In emergency situations, endovascular treatment, carotid ligation, or abscess drainage could be considered. Endovascular treatment and abscess drainage are temporary solutions. After the patient has recovered sufficiently, a more durable treatment i.e., open surgery is advised. Endo vacuum assisted closure (EndoVAC) seems to be promising. Further research is needed to determine the applicability of each treatment option.

Left ventricular aneurysm (LVA) and false aneurysm are complications of acute myocardial infarction, trauma, and cardiac surgery. Left ventricular false aneurysm (LVFA) is a particularly catastrophic complication owing to its high propensity for rupture. Surgical resection should be considered for LVFA occurring within three months after myocardial infarction or development of congestive heart failure. In this report, we describe a case of acute heart failure with LVA and LVFA occurring in stage as a complication of myocardial infarction in a 55-year-old man. The patient was also at risk of brain ischemia due to abnormal vessel status and a previous cerebrovascular accident with left-sided weakness. Successful perioperative anesthetic management was achieved by focusing on maintaining marginal upper normal blood pressure to ensure cerebral perfusion and to reduce the risk of false aneurysm rupture.

Objective To analyze the computational fluid dynamics (CFD) of femoral artery pseudoaneurysm (FAP), identify a suitable location and timing for percutaneous thrombin injection (PTI) based on this analysis, and report our clinical experience with the procedure. Materials and Methods CFD can be used to analyze the hemodynamics of the human body. An analysis using CFD recommended that the suitable location of the needle tip for PTI is at the center of the aneurysm sac and the optimal timing for starting PTI is during the early inflow phase of blood into the sac. Since 2011, seven patients (three male and four female; median age, 60 years [range, 43–75 years]) with FAP were treated with PTI based on the devised suitable location and time. Prior to the procedure, color Doppler ultrasonography was performed to determine the location and timing of the thrombin injection. Results The technical success rate of the PTI was 100%. The amount of thrombin used for the procedure ranged from 200 IU to 1000 IU (median, 500 IU). None of the patients experienced any symptoms or signs of embolic complications during the procedure. Follow-up CT images did not reveal any embolism in the lower extremities and showed complete thrombosis of the pseudoaneurysm. Conclusion Based on our study of CFD, PTI administered centrally in the FAP during early inflow, as seen on color Doppler, can be an effective technique.

Pseudoaneurysm is a rare long-term complication following coarctation of aorta repair. Thoracic endovascular aortic repair is the most common approach. However, under some circumstances, this cannot be performed. Therefore, the traditional open approach is indicated. Although the potential ischemia of spinal cord is related to this approach, it remains an efficient alternative. The authors report a case of late pseudoaneurysm of the distal aortic arch following coarctation of aorta repair in a 26-year-old male that has been successfully repaired by left thoracotomy.

This study evaluated the occurrence of false aneurysms and reflexes in bovines, associated with the point along the neck where the cut was performed. The survey was carried out on a total of 1200 male beef cattle, belonging mainly to the Charolais and Limousin breeds, aged between twelve and twenty-four months. In the slaughterhouse, three operators, identified by convention as Operator C4, Operator C2, and Operator C1, performed the Halal slaughtering. Each operator carried out the slaughter of 400 animals and, on the basis of his own professional training, performed the cutting of the vessels at different points along the neck: Operator C4 between the third and fourth cervical vertebrae, Operator C2 at the level of the second cervical vertebra, and Operator C1 at the first cervical vertebra. The occurrence of false aneurysms was assessed on the basis of the different cutting site used by the three operators. Then, the evaluation of consciousness indicators, that is, rhythmic breathing and eye response, closely related to a slow bleeding process and to a delayed loss of brain function, was carried out 90 s post-bleeding. The group of cattle slaughtered by Operator C4 had a prevalence of false aneurysms of 10.25%. Conversely, the other two groups of cattle slaughtered by Operators C2 and C1 showed false aneurysm formation in 7.25% of each case. Further, 37.5% of the animals (18 for Operator C4, 17 for Operator C2, and 16 for Operator C1) with signs of consciousness 90 s after sticking were consequent to the onset of false aneurysms and, more precisely, they were owing to a late second cut of the vessel carried out by the operator, when false aneurysms occurred. The results of the research showed that the cutting point chosen by the operator is a key element in determining the onset of false aneurysms.

We report a case of an 18-year-old woman who developed a delayed pseudoaneurysm of the right anterior tibial artery (ATA), 14 days after a knife accidental trauma. The patient was admitted to our emergency department for acute onset of pain in the right limb after a domestic trauma. At a physical examination, the limb was tense and tender, with a pulsatile mass in the anterior compartment. Femoral, popliteal, and distal pulses were palpable on both limbs. Duplex ultrasound scan (DUS) and computed tomography angiography showed the presence of an ATA pseudoaneurysm. An urgent endovascular treatment was performed under local anesthesia via percutaneous access. Pseudoaneurysm was excluded implanting 2 coronary covered balloon-expandable stents (BeGraft; Bentley Innomed GmbH, Hechingen, Germany). Postoperative course was uneventful and the patient was discharged on the second postoperative day under dual antiplatelet therapy. One- and 13-month scheduled follow-up visits and DUS revealed the presence of a normal pedal pulse, complete pseudoaneurysm exclusion, and patency of the stent grafts and the entire ATA with triphasic waveforms. In conclusion, endovascular treatment of an ATA pseudoaneurysm seems to be a feasible option. Further experience with this technique is needed to validate its safety and long-term patency, especially in young and healthy subjects.

Left ventricular pseudoaneurysm is a partial cardiac rupture, contained by the surrounding pericardium that maintains communication with the left ventricular lumen. Whereas most cases of left ventricular pseudoaneurysms are related to myocardial infarction (loss of myocardial integrity), only a handful are associated with valve surgery. We present a female patient, who was admitted for elective mitral valve replacement. After the implantation of the mechanical valve, we encountered a rupture of the atrioventricular groove. After 3 months, a left ventricular pseudoaneurysm was found and the patient was reoperated. The valve was explanted and the inspection of the annulus and previously implanted pericardial patch revealed a loosened stitch on the inferior (ventricular) side. The defect was reinforced with additional stitches and the valve was reimplanted. In conclusion, we report an unusual case with two serious complications after mitral valve replacement – atrioventricular groove rupture and left ventricular pseudoaneurysm.
