Common femoral vein aneurysms are rare and they are often misdiagnosed as soft tissue masses or as hernias. In this case report, we review literature and describe a patient who presented with left inguinal mass associated with ipsilateral limb swelling. He was initially misdiagnosed as cystic adventitial disease of common femoral vein. Later, he underwent surgical exploration and found out to have common femoral vein aneurysm which was treated by aneurysmectomy and lateral venorrhaphy. [ABSTRACT FROM AUTHOR]

Primary venous aneurysms are uncommon solitary dilatation of a vein that can occur throughout the venous system. Superficial venous aneurysms of the lower extremities are more often reported as esthetically displeasing bulges or incidental findings and are asymptomatic. A painful primary venous aneurysm is an extremely rare clinical entity. We report a case of painful thrombosed venous aneurysm of the great saphenous vein in a young male and managed surgically.

Background: A venous aneurysm (VA) is a focal dilatation of a nonvariceal vein (diameter increased by at least 1.5 times compared to the adjacent upstream or downstream venous segment), which carries a risk of venous thromboembolism (VTE) when located in the deep veins of the lower limbs but also when it affects the veins above the muscle fascia. Case: We report the case of a 40-year-old woman who presented with a painful and disabling mass-like lesion of the upper third of the right calf. A Doppler ultrasound (DUS) examination revealed a small saphenous vein (SSV) dilated at the saphenopopliteal junction (SPJ) and thrombosed along its entire length. Anticoagulant treatment was initiated but although the thrombosis regressed on DUS, the functional impotence and the persistence of pain prompted a stripping of the SSV. Histology allowed the diagnosis of SSV's primary aneurysm. Discussion: Dilated segments of the saphenous vein are not always varicose veins (VVs). True VAs can develop on veins located above the muscular fascia and, like deep VAs, may trigger VTE. Small saphenous vein aneurysms have seldom been reported, and only a few clinical observations have described the thrombosis of a SSV aneurysm. Any mass in the popliteal fossa or upper part of the calf should be examined by DUS to look for an SSV aneurysm. Excision of the saphenous vein with junctional ligation is advised if thrombosis is present at the time of diagnosis. [ABSTRACT FROM AUTHOR]

ObjectiveExtremity venous aneurysms result in the risk of pulmonary embolism (PE) and chronic venous insufficiency. At present, owing to the rarity of these aneurysms, no consensus for their treatment has been established. The purpose of the present study was to review the presentation, natural history, and contemporary management of extremity venous aneurysms.MethodsWe performed a retrospective, multi-institutional review of all patients with extremity venous aneurysms treated from 2008 to 2018. A venous aneurysm was defined as saccular or fusiform with an aneurysm/vein ratio of >1.5.ResultsA total of 66 extremity aneurysms from 11 institutions were analyzed, 40 of which were in a popliteal location, 14 iliofemoral, and 12 in an upper extremity or a jugular location. The median follow-up was 27 months (range, 0-120 months). Of the 40 popliteal venous aneurysms, 8 (20%) had presented with deep vein thrombosis (DVT) or PE, 13 (33%) had presented with pain, and 19 had been discovered incidentally. The mean size of the popliteal venous aneurysms presenting with DVT or PE was larger than that of those presenting without thromboembolism (3.8 cm vs 2.5 cm; P = .003). Saccular aneurysm morphology in the lower extremity was associated with thromboembolism (30% vs 9%; P = .046) and fusiform aneurysm morphology with a thrombus burden >25% (45% vs 3%). Patients presenting with thromboembolism were more likely to have had a thrombus burden >25% in their lower extremity venous aneurysm compared with those who had presented without thromboembolism (70% vs 9%). Approximately half of all the patients underwent immediate intervention, and half were managed with observation or antithrombotic regimen. In the non-operative cohort, three patients subsequently developed a DVT. Eight patients in the medically managed cohort went on to require surgical intervention. Of the 12 upper extremity venous aneurysms, none had presented with DVT or PE, and only 2 (17%) had presented with pain. Of the 66 patients in the entire cohort, 41 underwent surgical intervention. The most common indication was the absolute aneurysm size. Nine patients had undergone surgery because of a DVT or PE, and 11 for pain or extremity swelling. The most common surgery was aneurysmorrhaphy in 21 patients (53%), followed by excision and ligation in 14 patients (35%). Five patients (12%) had undergone interposition bypass grafting. A postoperative hematoma requiring reintervention was the most common complication, occurring in three popliteal vein repairs and one iliofemoral vein repair. None of the patients, treated either surgically or medically, had reported post-thrombotic complications during the follow-up period.ConclusionsLarge lower extremity venous aneurysms and saccular aneurysms with thrombus >25% of the lumen are more likely to present with thromboembolic complications. Surgical intervention for lower extremity venous aneurysms is indicated to reduce the risk of venous thromboembolism (VTE) and the need for continued anticoagulation. Popliteal aneurysms >2.5 cm and all iliofemoral aneurysms should be considered for repair. Upper extremity aneurysms do not have a significant risk of VTE and warrant treatment primarily for symptoms other than VTE.

Aneurysms of the external jugular vein (EJV) are uncommon vascular malformations. Due to their rarity, it is currently unclear what the risk of complications are and whether surgical management should be offered. The risks associated with the surgery need to be balanced with the risk of complications from the malformation. We present the case of a young woman who presented with a painful erythematous neck swelling who was found to have an aneurysm of the EJV with thrombophlebitis. This was successfully treated with surgical excision. We discuss current evidence for treatment of neck vein aneurysms and pitfalls. [ABSTRACT FROM AUTHOR]

Venous aneurysms are rare vascular malformations that can lead to significant clinical complications, including thrombosis, pulmonary embolism, rupture, and even fatal outcomes when not promptly and adequately managed. This case report presents a liver transplant patient under immunosuppressive therapy who developed a rapidly progressing great saphenous vein aneurysm, ultimately requiring urgent surgical intervention due to acute bleeding from the ruptured aneurysm. Immunosuppression emerges as a potential key factor in the formation and rapid growth of the aneurysm, with the pathophysiological mechanism potentially involving increased expression of specific matrix metalloproteinases. Further research is warranted to gain a better understanding of the role of immunosuppression in the development of venous aneurysms. [ABSTRACT FROM AUTHOR]

Vascular leiomyosarcoma LMS. is an extremely rare subgroup of LMSs. Fewer than 50 cases of LMS originating from the great saphenous vein have been reported. In 43% of reported cases, LMS was misdiagnosed clinically. In our case, the patient was initially misdiagnosed as having a thrombosed aneurysm. This misdiagnosis could be due to the rarity of great saphenous vein LMS cases, for which a high index of suspicion is needed, and because no specific radiologic findings have been established for diagnosing LMSs. Masses presenting along the course of vessels should be suspected for malignancy, which can be helpful in performing definitive surgery and avoiding multiple surgeries.

The anatomical variations in the lower limb veins play a critical role in venous reflux surgeries. This study presents an analysis of the great saphenous vein (GSV) proximal part’s anatomical peculiarities, with 257 patients included, who were operated for venous reflux. This study highlighted a progressive increase in the GSV diameter in conjunction with the complexity of the anatomical variations, ranging from no tributaries to more than five tributaries, an anterior accessory GSV, or venous aneurysms. Statistical analysis evidenced this expansion to be significantly correlated with the variations. Additionally, the progression of the chronic venous disease (CVD) stages was notably more prevalent in the complex anatomical variations, suggesting a nuanced interplay between the GSV anatomy and CVD severity. Conclusively, our research articulates the paramount importance of recognizing GSV anatomical variations in optimizing surgical outcomes for CVD patients. These insights not only pave the way for enhanced diagnostic accuracy but also support the strategic framework within which surgical and interventional treatments are devised, advocating for personalized approaches to venous reflux surgery.

An iliac vein aneurysm is a rare vascular anomaly, scarcely reported in the vascular literature. We present the case of a 72-year-old man with a history of a remote heart transplant complicated by severe tricuspid regurgitation and traumatic abdominal injury, who was incidentally found to have a 10-cm right common iliac vein aneurysm. Because of the size and risk of rupture, we elected to treat him with surgical iliac vein aneurysmorrhaphy. His iliac venous diameter and flow continued to be stable at subsequent follow-up.

A 72-year-old man receiving anticoagulation therapy for chronic bilateral deep vein thromboses presented with acute right leg swelling. Right-sided imaging showed deep femoral vein thrombosis, chronic partial femoral vein thrombosis, and 4.8-cm distal external iliac vein dilation with possible right iliac vein stenosis. Venography confirmed common iliac vein occlusion and an aneurysm, with a fistula to the right internal iliac artery found by angiography. Aneurysm obliteration was achieved via arterial embolization with coils and an Amplatzer plug (Abbott, Chicago, IL). The patient continued with anticoagulation therapy, with patent common and external iliac arteries and a stable right external iliac vein aneurysm without arterial waveforms found on follow-up. His clinical manifestations were improved.

Background: Superficial vein aneurysms (SVA) are rare vascular pathologies associated with trauma, chronic venous disease, and venous malformation. Method: We retrospectively reviewed cases of SVA treated from 1986 to 2022. Results: Out of 2463 venous procedures, 16 patients were found with 19 GSV and 1 SSV aneurysms, with 88% presenting with a palpable mass. Varicose veins were noted in 94% of patients, 81% had concomitant reflux, 15% had thrombus within the aneurysm sac, and 19% demonstrated multiple aneurysms. All patients underwent ligation and excision. Post-procedure, 55% of patients received anticoagulants, and 85% received compression. Mean follow-up was 19.4 months, with no aneurysm recurrence. We propose a modification to the current SVA classification. Conclusion: The prevalence of multiple aneurysms suggests the need for complete limb imaging in affected patients. Surgical management of SVA was effective in preventing SVA recurrence, while the proposed classification modification will aid in future SVA management. [ABSTRACT FROM AUTHOR]

The occurrence of venous aneurysms (VAs) is very rare, and VAs have been seldom reported in the existing literature. The etiology leading to the formation of VAs has not yet been determined. The presentation can range from asymptomatic to painful thrombosis of the sac, with rare events of pulmonary embolism. We have reported the case of a patient who had had a large cephalic vein aneurysm that was treated successfully. A 39-year-old man had presented with swelling in the left forearm that had progressively increased in size for 2 years and was associated with discomfort. On examination, a 5 × 5-cm soft compressible lesion was present over the mid-forearm that disappeared with raising of the arm. Contrast-enhanced magnetic resonance imaging showed a well-defined lesion arising from the cephalic vein. Under local anesthesia, after proximal and distal ligation, the aneurysm was excised. The histopathologic examination showed a thinned out smooth muscle wall and multifocal absence of the smooth muscle layer. The patient was doing well at 1 year of follow-up with no further degeneration in the vein wall. The formation of VAs might result from endophlebohypertrophy and endophlebosclerosis of the veins at the site of recurrent stress. Surgical excision should be considered when the patient is symptomatic, cosmetic disfigurement is present, and/or complications such as venous thrombosis, pulmonary embolism, and/or nerve compression have developed.

Portal vein aneurysm (PVA) is a rare vascular entity. Here, we describe cases of 2 separate patients who presented with congenital and acquired causes of PVA respectively. The first patient presented with vague abdominal pain and was incidentally diagnosed with PVA, whereas the cause in the second patient was iatrogenic. With a limited number of cases published to date, there is little data on the natural history of the disease. Herein, we will discuss the radiological findings aiding us in reaching our diagnosis and also the probable mimickers of the disease, with a brief overview of its possible causes, complications, and the currently available management options.

Aneurysms of the iliac veins are very rare; thus, the best approach to management has not yet been defined. We have presented the case of a 17-year-old boy with incidentally identified large bilateral external iliac vein aneurysms. Given the risks of potentially fatal thromboembolism or rupture, he underwent definitive repair of his aneurysms using staple aneurysmorrhaphy combined with additional vein tailoring by suture venoplasty, a technique not previously described for these aneurysms. We have also discussed the etiology, presentation, and our surgical technique to manage this rare condition.

Venous aneurysms are rare vascular malformations that can lead to significant clinical complications, including thrombosis, pulmonary embolism, rupture, and even fatal outcomes when not promptly and adequately managed. This case report presents a liver transplant patient under immunosuppressive therapy who developed a rapidly progressing great saphenous vein aneurysm, ultimately requiring urgent surgical intervention due to acute bleeding from the ruptured aneurysm. Immunosuppression emerges as a potential key factor in the formation and rapid growth of the aneurysm, with the pathophysiological mechanism potentially involving increased expression of specific matrix metalloproteinases. Further research is warranted to gain a better understanding of the role of immunosuppression in the development of venous aneurysms.

A lower extremity venous aneurysm is an uncommon vascular disease known to increase a patient’s risk of pulmonary embolism. Although most will be popliteal venous aneurysms, crural aneurysms have been rarely documented. We have presented a rare case of a soleal venous aneurysm in a patient with a history of pulmonary embolism. Risk-reducing open aneurysm resection with lateral venorrhaphy was performed.

Inferior vena cava (IVC) aneurysms are an extremely rare entity, but can be life threatening for their complications including pulmonary embolism and rupture. We report a new case of saccular type III IVC aneurysm presented with thrombosis and complicated by bilateral phlegmasia cerulea dolens (PCD). The challenge was twofold, treat the PCD and the IVC aneurysm.

A 63-year-old man with multiple previous orthopedic procedures in both lower extremities had presented to us for a third opinion regarding the point-specific pain in his right lateral calf. The initial diagnosis had been venous reflux at two other institutions. However, repeat imaging studies demonstrated an aneurysmal gastrocnemius vein without any other abnormalities, such as venous reflux or thrombosis. The patient had received compression stocking therapy for 6 months but had continued to experience increasing pain at night, especially when lying in bed. The patient was reexamined in the supine position, which showed a prominent bulge in the lateral calf. The bulge disappeared while he was in the upright position. The findings from a bedside ultrasound study confirmed that the gastrocnemius vein bulged out when the muscles were relaxed in the supine position and that the muscles compressed the vein in the standing position, squeezing the aneurysm. Thus, the decision was made to proceed with surgical excision. At 7 months after surgery, the patient remained symptom free.

Background: In general, venous aneurysm associated with dural arteriovenous fistula (dAVF) is considered to be developed under long standing venous hypertension and manifested as venous ectasia of draining vein itself. However, discrete saccular shaped venous aneurysm without angiographic evidence of venous hypertension arising from the draining vein, like cerebral arterial aneurysm, is quite rare and its pathomechanism remains unclear in patients with dAVF., Case Summary: In this report, we present two cases of ruptured saccular venous aneurysms associated with dAVF without venous hypertension or venous ectasia. In both cases, significant curve or stenosis is observed in draining vein, which is located in just distal portion of the venous aneurysms. These aneurysms were successfully treated with a transarterial embolization. Underlying mechanism of venous aneurysms in these cases is discussed., Conclusion: Although there is little doubt that hemodynamic stress has a critical role in the development of venous aneurysms in patients with dAVF, preceding venous hypertension or venous ectasia is not necessary for development and enlargement of venous aneurysms. Considering the significant risk of rupture, a careful review of draining vein features including tortuosity or stenosis is needed, especially in venous aneurysms without evidence of venous hypertension., Competing Interests: Conflict-of-interest statement: There is no conflict-of-interest to declare., (©The Author(s) 2024.

Great saphenous vein aneurysms (GSVA) represent a rare yet clinically significant condition, often misdiagnosed due to their infrequent presentation and resemblance to more common inguinal pathologies. This case series examines five instances of GSVA, emphasizing the diagnostic challenges, surgical interventions, and postoperative outcomes. Patients presented with varying symptoms, including groin masses and lower extremity pain, which were initially misattributed to other conditions. Imaging techniques, primarily venous duplex ultrasound, played a crucial role in identifying the aneurysms and guiding surgical planning. Surgical treatment, including aneurysm excision and ligation, was performed in all cases, with most patients experiencing uncomplicated postoperative courses. However, the risk of recurrence and thromboembolic events, such as pulmonary embolism, remains a concern, particularly in cases involving more proximal aneurysms near the deep venous system. Despite the success of surgical intervention, there is no consensus on the management of asymptomatic GSVA, nor are there standardized treatment guidelines. This case series highlights the need for heightened awareness among clinicians regarding GSVA, the importance of accurate diagnosis, and the consideration of prompt surgical treatment to prevent severe complications. Further research is needed to establish clear guidelines for managing both symptomatic and asymptomatic GSVA, particularly in relation to thromboembolic risk., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Popliteal arteriovenous fistulae (PAF) are anomalous communications between the arterial and venous systems of the lower extremity. They are usually secondary to trauma and are rarely associated with additional vascular defects. The coexistence of a PAF and a venous aneurysm is rare and usually occurs in patients with connective tissue disorders. Evidence regarding the management of this type of anomaly is scarce. However, both open and endovascular approaches seem feasible alternatives for treating this condition. Here, we describe a spontaneous popliteal arteriovenous fistula associated with a venous aneurysm in a 42-year-old male patient who presented with a popliteal mass. Satisfactory endovascular closure of the fistula and exclusion of the venous aneurysm were achieved using an Amplatzer™ Vascular Plug II. [ABSTRACT FROM AUTHOR]

Abstract Background Mycotic aneurysms are rare vascular lesions, occurring in 0.6–2% of arterial aneurysms but with no reported venous cases. Venous aneurysms unrelated to an underlying infectious process have been previously described and are typically surgically repaired due to risk of thromboembolic events. Case presentation This case reports a bleeding external iliac vein mycotic aneurysm secondary to erosion of a chronic pelvic abscess, successfully treated with endovascular stenting, in an oncologic patient without alternative therapeutic options. Conclusion Venous aneurysms are uncommon vascular lesions which have historically been treated with open surgical repair. Given the lower degree of procedural morbidity, endovascular management of these lesions may be an effective option in the appropriate setting, particularly as a last resort in patients without surgical treatment options.

Superficial venous aneurysms are a very rare pathology. This case report describes a 21-years-old male patient, who developed a soft, slow-growing mass, in the lateral part of the dorsal foot. Based on clinical examination and EcocolorDoppler ultrasound exam, the diagnosis of venous aneurysm of the lateral marginal vein was confirmed. The treatment proposed was ultrasound-guided foam sclerotherapy. The purpose of this work is to describe for the first time a venous superficial aneurysm localized in the lateral marginal vein of the foot. It is the first case reported in English literature.

Abstract Background Aneurysm of the left brachiocephalic vein is a very rare clinical disease and only 40 cases have been reported so far. Case presentation The patient was a 61-year-old woman with no related medical history. She underwent CT to investigate the cause of a cough and a mass was noted in the anterior mediastinum. Dynamic computed tomography with contrast medium injected into the left basilic vein demonstrated the venous aneurysm with blood flow to the left brachiocephalic vein. The patient had no symptoms, but because of the risk of pulmonary infarction and aneurysm rupture, the aneurysm was surgically resected. A median sternotomy was a reasonable approach because of the fragility of the venous aneurysm wall with little working space in the anterior mediastinum. Conclusions We diagnosed an aneurysm of the left brachiocephalic vein on preoperative imaging and excised it through a median sternotomy. The venous wall was thin and fragile in some areas and so this approach was appropriate in view of the possibility of intraoperative injury.

Portal vein aneurysms are rare pathologic entities. A 3.7-cm portal vein aneurysm was incidentally discovered in an 80-year-old male patient on imaging for acute abdominal pain secondary to an incarcerated diaphragmatic hernia. The aneurysm was resected, and primary repair of the portal vein was performed during a second-look operation after repair of the incarcerated hernia. Operative intervention was chosen for this patient because of the aneurysm's size and the additional indication for abdominal exploration.

Objective: We sought to assess the diagnostic yield of advanced noninvasive imaging in the evaluation of patients with pulsatile tinnitus. Background: Pulsatile tinnitus can be caused by high-risk cerebrovascular pathologies such as arteriovenous fistulae. The role of advanced noninvasive imaging, including magnetic resonance angiography and magnetic resonance venography, in the diagnostic evaluation of pulsatile tinnitus is not well defined. Design and methods: We performed a retrospective cohort study of patients presenting for outpatient diagnostic evaluation of pulsatile tinnitus from January 2018 to March 2020 at Weill Cornell Medicine. Patients with non-pulsatile tinnitus and established etiologic diagnoses were excluded. Systematic chart abstraction was summarized using standard descriptive statistics. Univariate logistic regression was used to identify factors associated with nondiagnostic noninvasive imaging. Results: A total of 187 patients (139 (74.3%) women) took part in this study, with a mean age of 48.6 years (standard deviation (SD) = 15.5 years) and a mean body mass index (BMI) of 26.9 kg/m2 (SD = 6.1 kg/m2). Of the 187 patients, 121 (64.7%) underwent exclusively noninvasive imaging, and 66 (35.3%) patients also had digital subtraction angiography (DSA). In patients who had exclusively noninvasive imaging, 62 (51.2%) patients received a diagnosis. In patients who underwent noninvasive and DSA imaging, 14 (21.2%) patients received a diagnosis based on DSA. Patients who were older at symptom onset (odds ratio (OR) = 1.05; 95% confidence interval (CI) 1.01–1.09) and those with a lower BMI (OR = 0.88, 95% CI 0.77–0.98) were more likely to have nondiagnostic noninvasive imaging. Conclusion: Noninvasive cerebrovascular imaging often uncovers the etiology of pulsatile tinnitus. DSA remains useful for additional evaluation for patients with specific associated features.

Although venous aneurysms are rare, typically asymptomatic, and most commonly found incidentally on imaging studies, patients with this pathology can develop pulmonary emboli owing to these aneurysms acting as a nidus for thrombus formation. There is no clear consensus regarding conservative management with anticoagulation vs operative intervention as the best treatment of deep venous aneurysms. We report the clinical course and surgical treatment of a patient presenting with both bilateral common femoral vein and bilateral popliteal venous aneurysms who had a known history of prior symptomatic pulmonary emboli.

Venous system aneurysms appear relatively rarely and are diagnosed even less frequently, especially if asymptomatic. Asymptomatic aneurysms are detected during duplex-Doppler studies. Symptomatic aneurysms are often life-threatening. The first part of this paper presents a literature review of this rare disease, and the second part presents a the material of the cochort of 5 patients underwent surgical treatment due to venous aneurysm and its complications. There is no clear standard of treatment for venous aneurysms. The main reasons for this are relatively low epidemiology, diversity of locations, difficulty in establishing primary and secondary aetiologies, anatomical structure, and the coexistence of concomitant diseases. Given the numerous uncertainties, several factors should be considered when deciding the next steps in treatment. [ABSTRACT FROM AUTHOR]

Internal jugular venous aneurysm (IJVA) is a rare entity that usually remains asymptomatic with only rare complications. We report two cases of IJVA. Both patients presented with a palpable soft tissue mass in the neck and were found to have IJVA on imaging with associated lymphadenopathy. In both cases, the aneurysms and involved lymph nodes were resected, with the jugular vein being primarily reconstructed. There are only a few case reports involving IJVA, and treatment guidelines are not well established. Whereas nonoperative management is frequently chosen, the most common indication for surgery is cosmetic; both management options have favorable outcomes.

Venous aneurysms continue to be one of the little studied sections of modern vascular surgery. Messages on the occurrence of this pathology in the medical literature are very few and describe extremely rare clinical cases, localized mainly in the deep veins of the lower extremities and leading to thromboembolic complications. Single publications describe venous aneurysms localized in superficial saphenous veins. The etiology and pathogenesis of this disease currently continues to cause debate. The article provides a literature review on this rare surgical vascular pathology, presents its own clinical observation, discusses the issues of diagnosis and treatment options for this disease.

Abstract Background Mediastinal venous aneurysm is a very rare disease and can be easily misdiagnosed. Patients are often asymptomatic while venous aneurysm of large size with adjacent structures oppressed can lead to discomfort. The surgical treatment for aneurysm of large vessels is often complex and challenging. Case presentation We reported a 52-year-old man with mediastinal mass who received operation on July 2019 in our hospital. Left innominate vein aneurysm was diagnosed during operation with superior vena cava involved. The aneurysm was resected and pericardium was taken to repair part wall of superior vena cava and reconstruct left innominate vein. The patient’s postoperative course was uneventful. Conclusions Venous aneurysm should be considered when mediastinal mass has no clear boundary with large veins or even seems to connect with them. Magnetic resonance imaging, computed tomographic angiography and invasive venography can be performed to further evaluate the mass once diagnosis of venous aneurysm was suspected. Using pericardium to repair large veins is a good choice which is safe and costless.

The anatomical variations in the lower limb veins play a critical role in venous reflux surgeries. This study presents an analysis of the great saphenous vein (GSV) proximal part's anatomical peculiarities, with 257 patients included, who were operated for venous reflux. This study highlighted a progressive increase in the GSV diameter in conjunction with the complexity of the anatomical variations, ranging from no tributaries to more than five tributaries, an anterior accessory GSV, or venous aneurysms. Statistical analysis evidenced this expansion to be significantly correlated with the variations. Additionally, the progression of the chronic venous disease (CVD) stages was notably more prevalent in the complex anatomical variations, suggesting a nuanced interplay between the GSV anatomy and CVD severity. Conclusively, our research articulates the paramount importance of recognizing GSV anatomical variations in optimizing surgical outcomes for CVD patients. These insights not only pave the way for enhanced diagnostic accuracy but also support the strategic framework within which surgical and interventional treatments are devised, advocating for personalized approaches to venous reflux surgery.

Purpose: The iliac veins are the least frequent location for venous aneurysms, with only a few cases described globally. The etiology and clinical presentation of this extremely rare entity is diverse and unclear and no treatment consensus has been reached yet. Our purpose is to present an interesting iliac vein aneurysm (IVA) case that we treated in our department, with a brief review of the literature., Case Report: We report a case of a 74-year-old male patient with a giant, 55 mm in diameter, asymptomatic, right common IVA, with concurrent aplasia of the left common iliac vein and an extensive network of venous collaterals. The patient was treated, under general anesthesia, with total endovascular iliocaval reconstruction through implantation of a 32 × 100 mm thoracic aortic tubular Ankura stent graft. The computed tomography venography at first-month follow-up showed the complete exclusion of the IVA, without any endoleak and the patient remains up to date free of symptoms and thromboembolic events., Conclusion: Twelve cases of endovascular treatment of IVA have been reported so far, and our case is the first with implantation of a thoracic aortic stent graft. Our results suggest that this technique is safe, effective, and may be considered for appropriately selected patients., Clinical Impact: This is the first case with total endovascular repair of an iliac vein aneurysm with contralateral iliac vein aplasia through endovenous implantation of a thoracic aortic stent-graft. Our results suggest that this technique is safe and effective and thus, may be considered for appropriately selected cases., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Venous aneurysms of the head and neck region are very uncommon. Aneurysms of the external jugular vein in children are exceedingly rare, and consequently the best approach to diagnosis and management has not been clearly defined. We present the case of a 15-year-old girl with a non-pulsatile, occasionally painful, enlarging fullness in her right supraclavicular fossa and neck. Imaging demonstrated a large and complex right external jugular vein aneurysm with thrombus. Given the symptomatic nature of this aneurysm, recurrent episodes of thrombosis, and the risk of thromboembolism, she underwent surgical excision. Thorough pre-operative planning with additional imaging to better understand the anatomy of this aneurysm was critical to a safe and successful intervention.

Cystic hygromas (CH) are congenital malformations of the lymphatic system and consists of internal cystic areas of variable sizes. CH is commonly seen in the cervicofacial region, axilla, mediastinum, groin and abdominal viscera. CH can be asymptomatic if small however can cause variable symptoms from respiratory distress to infection. It has been associated with number of syndromes and pathologies however its association with venous anomalies and aneurysm has been rarely reported in the literature. We report a case of cystic hygroma in left submandibular region with venous aneurysm of the left common facial vein and ectatic lingual vein. [ABSTRACT FROM AUTHOR]

Background: Mycotic aneurysms are rare vascular lesions, occurring in 0.6–2% of arterial aneurysms but with no reported venous cases.

Case presentation: This case reports a bleeding external iliac vein mycotic aneurysm secondary to erosion of a chronic pelvic abscess, successfully treated with endovascular stenting, in an oncologic patient without alternative therapeutic options. Conclusion: Venous aneurysms are uncommon vascular lesions which have historically been treated with open surgical repair. Given the lower degree of procedural morbidity, endovascular management of these lesions may be an effective option in the appropriate setting, particularly as a last resort in patients without surgical treatment options.

Objective: External jugular vein (EJV) aneurysm is an extremely uncommon clinical condition. We have studied the clinical profile and need for surgery in this present seven case series of primary external jugular vein aneurysms. Method: Over the past three years, we have diagnosed and managed aneurysms of external jugular vein in seven patients, who presented with swelling in the posterior triangle of the neck. Venous duplex was obtained in all the patients, followed by computed tomography (CT) in three patients and one patient reported with magnetic resonance (MR) venography from another hospital. Three patients had symptoms ranging from mild intermittent discomfort to moderate pain underwent excision of aneurysm after ligation of both ends of EJV. Four patients had swelling on the lateral side of the neck due to EJV aneurysm, with no other associated symptoms. They were kept on six monthly follow-ups. Result: We operated three patients, as they were symptomatic, of which only two had thrombus in the aneurysmal sac. All three symptomatic patients had aneurysm of size >5 cm. Post-surgery and on subsequent follow-ups they were asymptomatic. The four asymptomatic patients kept on conservative management did not develop any thrombosis of aneurysm sac in follow up. Conclusion: Surgical excision is indicated for symptomatic patients with EJV aneurysm, preferably for size > 5 cm because of their higher association with thrombosis or symptoms. Asymptomatic patients can be managed non-operatively with regular surveillance by clinical examination and venous duplex or can be treated if patients insist due to cosmetic reasons.

Objectives: This prospective study evaluates the effectiveness and safety of venous sinus stenting for patients with isolated pulsatile tinnitus and lateral sinus stenosis. Methods: Patients with isolated pulsatile tinnitus and lateral sinus stenosis with a minimum trans stenotic gradient of 4 mm Hg were treated with stenting. Pulsatile tinnitus before and after treatment was assessed with the Tinnitus Handicap Inventory (THI). Periprocedural adverse events, neurological complications, clinical and radiographic follow-up were also recorded. Results: A total of 42 patients (41 females and 1 male) were included in the study (median age of 37.5 years). Thirty patients had post-stenotic fusiform and 12 had post-stenotic saccular venous sinus aneurysm. In addition to stenting, coils were used to treat the patients with saccular venous aneurysms. The median follow-up was 5 months (range 1 to 34 months). Most patients had complete (39/42) or near-complete (2/42) resolution of their pulsatile tinnitus post-procedure. There were no serious adverse events. Conclusion: Stenting of the lateral venous sinus is a safe and effective treatment for patients with isolated pulsatile tinnitus due to venous sinus stenosis.

Background: Aneurysm of the left brachiocephalic vein is a very rare clinical disease and only 40 cases have been reported so far. Case presentation: The patient was a 61-year-old woman with no related medical history. She underwent CT to investigate the cause of a cough and a mass was noted in the anterior mediastinum. Dynamic computed tomography with contrast medium injected into the left basilic vein demonstrated the venous aneurysm with blood flow to the left brachiocephalic vein. The patient had no symptoms, but because of the risk of pulmonary infarction and aneurysm rupture, the aneurysm was surgically resected. A median sternotomy was a reasonable approach because of the fragility of the venous aneurysm wall with little working space in the anterior mediastinum. Conclusions: We diagnosed an aneurysm of the left brachiocephalic vein on preoperative imaging and excised it through a median sternotomy. The venous wall was thin and fragile in some areas and so this approach was appropriate in view of the possibility of intraoperative injury. [ABSTRACT FROM AUTHOR]

Background: Sphenoid wing dural arteriovenous fistula (SWDAVF) is rare that is typically fed by middle meningeal artery feeders and that drain through the sphenoparietal sinus or middle cerebral vein. Here, we report a case of SWDAVF treated by coils placed in the venous aneurysm through the contralateral cavernous sinus (CS). Case Description: A 37-year-old woman was admitted to our hospital with headache and bilateral oculomotor nerve palsy. Magnetic resonance images and an angiogram showed a venous aneurysm in the right middle cranial fossa. A DAVF, consisting of two main feeders, was diagnosed based on the angiogram findings. The fistula drained into the left inferior petrosal sinus (IPS) through the left CS and right IPS. Given the remarkable extent of venous ectasia together with the headache and right abducens nerve paralysis, endovascular treatment was initiated. A transvenous approach through the right IPS was not feasible, as it is strenuous to insert the microcatheter into the right IPS. Thus, we tried an approach through the left IPS. The venous aneurysm was embolized with coils. The postoperative course was uneventful, and postoperative cerebral angiography confirmed disappearance of the fistula. Conclusion: A SWDAVF is extremely rare. In our case, since the AVF drained into the contralateral CS, contralateral ocular symptoms occurred. Endovascular occlusion of the venous aneurysm and fistula was achieved through a transvenous approach. [ABSTRACT FROM AUTHOR]

Abstract Background Aneurysms of the deep lower limbs veins are extremely rare. Diagnosis of such conditions may be confusing and suggest the presence of a neoplastic lesion. Case presentation We herein report a case of a 68-year-old woman who was admitted with a large vein tumour revealed by sonography and computed tomography. A direct phlebography revealed a large venous aneurysm of the right common iliac vein with an adhering thrombus and a large collateral circulation. Anticoagulant treatment and compression with an elastic stocking were initiated because the patient refused surgical treatment. A 2-year follow-up showed no aneurysm growth or thromboembolic complications. Conclusions We show herein that conservative management can be effective and safe in cases of this rare condition.

Portal vein aneurysms are rare vascular findings for which there are no optimal treatment guidelines. The scarce knowledge about their etiology, natural history, and management mean that there are limited treatment options. Here, we describe the case of a 69-year-old woman who presented with a 35-mm hypoechoic area in the hilar region of the liver that was accidentally detected by ultrasonography. Color Doppler ultrasonography demonstrated a mass with internal flow contiguous with portal vein, which was confirmed to be a portal vein aneurysm by computed tomography. Given that she experienced no symptoms of impending rupture or thrombosed aneurysms, we adopted a conservative treatment. Follow-up imaging demonstrated slow progression of the aneurysm diameter, from 35 to 43 mm at 3 years, and to 48 mm at 6 years; subsequent imaging after 6 years did not show any change in the diameter from 48 mm. However, the portal vein aneurysm completely regressed with no complications at a follow-up of over 10 years. This case suggests that long-term observation with periodic imaging may be an acceptable therapeutic option for asymptomatic portal vein aneurysms that show no short-term improvement. This case report contributes to a better understanding of how to treat this rare disease. [ABSTRACT FROM AUTHOR]

Background: Mediastinal venous aneurysm is a very rare disease and can be easily misdiagnosed. Patients are often asymptomatic while venous aneurysm of large size with adjacent structures oppressed can lead to discomfort. The surgical treatment for aneurysm of large vessels is often complex and challenging.Case Presentation: We reported a 52-year-old man with mediastinal mass who received operation on July 2019 in our hospital. Left innominate vein aneurysm was diagnosed during operation with superior vena cava involved. The aneurysm was resected and pericardium was taken to repair part wall of superior vena cava and reconstruct left innominate vein. The patient's postoperative course was uneventful.Conclusions: Venous aneurysm should be considered when mediastinal mass has no clear boundary with large veins or even seems to connect with them. Magnetic resonance imaging, computed tomographic angiography and invasive venography can be performed to further evaluate the mass once diagnosis of venous aneurysm was suspected. Using pericardium to repair large veins is a good choice which is safe and costless. [ABSTRACT FROM AUTHOR]
