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]

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]

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]

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]

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]

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.

Type 4 retro-aortic left renal vein (RLRV) and renal vein aneurysms are rare entities which may have clinical and surgical implications. Here we present computed tomography (CT) angiography images of a case of retro-aortic left renal vein draining into the left common iliac vein with a venous aneurysm. [ABSTRACT FROM AUTHOR]

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. 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.

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]

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]

Venous aneurysms in the upper limbs are a rare disease and are often misdiagnosed as benign tumors of soft tissues. Conservative treatment is considered in the absence of symptoms caused by venous aneurysms. However, if symptoms are present, surgical resection or vascular ligation of venous aneurysm may be necessary. A 56-year-old woman with no specific medical history and traumatic history of hand developed tenderness and radiation pain due to the palmar mass of her left hand and was diagnosed as venous aneurysm. After resection and ligation of venous aneurysm, patient's symptoms disappeared and there was no recurrence. Careful examination of the mass causing the symptom is necessary and the possibility of venous aneurysm should be considered. [ABSTRACT FROM AUTHOR]

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.

Objectives Venous aneurysms are uncommon. They can involve both superficial and deep venous systems. We hereby present a unique case of gastrocnemius venous aneurysm developed after compressive knee trauma. Report A large venous aneurysm in the left popliteal fossa was detected by chance in a 44-year-old woman one month after a compressive trauma to the posterior surface of the knee. Magnetic resonance-imaging of the same knee had documented normal venous anatomy one year earlier. The venous aneurysm involved the medial gastrocnemius vein near its confluence in the popliteal vein and was surgically resected. Histopathology evidenced a true venous aneurysm. The patient was discharged under oral anticoagulation for three months. At one year follow-up, neither complications nor new venous aneurysm development was detected. Conclusions An accurate evaluation of the venous system is always mandatory after limb traumas which may lead to post-traumatic venous pseudo-aneurysms, as well as more rarely, true venous aneurysms in the lower extremities. [ABSTRACT FROM AUTHOR]

Lower extremity superficial venous aneurysms are occasionally encountered by clinicians and are almost always located above the knee. Very few cases of aneurysm of the medial marginal vein in the most distal part, near the origin of the great saphenous vein, have been reported. We present a case of partially thrombosed aneurysm of the medial marginal vein, and briefly review the imaging characteristics and treatment options of this entity. Being aware of the existence of superficial venous aneurysms may help clinicians in their differential diagnosis of foot masses and choice of appropriate treatment. [ABSTRACT FROM AUTHOR]

Superficial venous aneurysms, which are mostly asymptomatic and detected when patients were referred to for the treatment or evaluation of a femoral or inguinal hernia or soft tissue masses, are associated with a risk of developing pulmonary embolism. We aimed to present a case of a greater saphenous vein aneurysm of which its misdiagnosis possesses morbidity risk and confused with inguinal hernia. A 45-year-old female patient admitted to our clinic with swelling and pain in her right groin that had been present for about three years. The patient was also treated with inguinal hernia repair once due to her related complaints. A venous color doppler ultrasound was performed for differential diagnosis and a 70x31-mm sized fusiform proximal greater saphenous vein aneurysm and a grade-4 pathologic reflux in the right saphe-nofemoral junction was observed in the ultrasonographic examination. As a result, the swelling detected in the inguinal region should be evaluated in terms of possible superficial venous aneurysm, which may cause thromboembolism and ruptures, and this condition, which is frequently confused with inguinal hernia, should be taken into consideration and taken under operation as soon as possible in case of its presence.

Introduction: Isolated venous aneurysm is defined as an focal vascular dilatation that communicates with normal size venous structure through a single channel, and it should not have any association with an arteriovenous communication or a pseudoaneurysm. Venous aneurysms may rarely be thrombosed. Herewepresenta female patient with thrombosed venous aneurysm of the small saphenous vein. Case Report: A 49 year-old woman was admitted to our hospital with complaints of a growing mass at the left popliteal region during the last 18 months. Physical examination revealed a firm subcutaneous mass on the left popliteal region. Color flow duplex imaging (CFDI) confirmed thrombosed saccular venous aneurysm of the small saphenous vein extending to the saphenopopliteal junction (SPJ) that measured approximately 3.2 cm in diameter. Surgical intervention was performed under spinal anesthesia. The aneurismal mass was relatively thin walled and was occluded by blood clot. Her postoperative course was uneventful and her symptoms resolved. Histologic findings were consistent with venous aneurysm. Conclusion: In order to prevent the risk of deep venous thrombosis and even pulmonary embolism, we think that thrombosed venous aneurysms close to the saphenopopliteal junction should be operated without delay. [ABSTRACT FROM AUTHOR]

The vast majority of perimesencephalic subarachnoid hemorrhage cases are reported as negative-finding etiologies. Recently, high-resolution images allowed us to overcome the previous difficulty of finding the source of bleeding, which underlies the concept of a 'negative finding'. We discovered a venous etiology, hidden behind the tip of the basilar artery; namely, the lateral pontine vein. Here, we review the literature on perimesencephalic subarachnoid hemorrhage and on venous aneurysm. We highlight this type of aneurysm as a candidate source of perimesencephalic hemorrhage. This case may change our way of dealing with what we have termed a negative finding of subarachnoid hemorrhage. [ABSTRACT FROM AUTHOR]

Introduction: Cerebral cortical venous aneurysm also known as cerebral varix is a rare entity that usually occurs in relation to high-flow draining veins of arteriovenous fistulas, arteriovenous malformations, and venous angioma. Isolated cerebral varix is an extremely rare entity. Case report: We present a 1-year-old male with isolated cerebral varix. During follow-up, the varix thrombosed spontaneously without causing any neurological deficits. Conclusion: To the best of our knowledge, spontaneous asymptomatic thrombosis of an isolated cerebral varix without any clinical finding was reported for the first time in the literature. [ABSTRACT FROM AUTHOR]

Venous aneurysm is saccular or fusiform dilatation of vein, usually congenital origin. Among acquired variety post intravenous cannulation leading to venous aneurysm is extremely rare entity. Non invasive diagnostic procedure MRI and duplex scanning are very useful modality for anatomical localization of the aneurysm. Although an ascending venogram is an invasive test and should take a backseat for diagnosis of such aneurysm. Symptometic case needs surgical management. Anatomical delineation is an important pre requisite for planning surgery. Aneurysmorrhaphy preserves the affected venous segment because it does not produce luminal compromise. [ABSTRACT FROM AUTHOR]

Background Venous aneurysms of the upper torso are uncommon in contrast to the abdomen and lower extremities. Mostly silent, they can cause significant morbidity. Large or symptomatic venous aneurysms are generally treated with open resection. To our knowledge, there are no documented cases of head and neck venous aneurysms treated by a hybrid endovascular and open approach. Case Presentation A 56-year-old female presented with the complaint of pain and increasing size of a supraclavicular mass. Imaging revealed a large saccular aneurysm of the subclavian vein with the presence of a large intramural thrombus on computed tomography scan with contrast. A covered stent was deployed in order to exclude the aneurysm from circulation. Three weeks later, the symptoms continued, and an aneurysmorrhaphy was performed to excise the stent and aneurysm resection. Discussion A combined endovascular and open approach to resection of symptomatic subclavian vein aneurysms is a viable method with minimal morbidity. [ABSTRACT FROM AUTHOR]

Azygous Vein Aneurysm (AVAs) is an uncommon cause of mediastinal mass. They are typically asymptomatic and do not commonly require treatment. They may mimic mediastinal adenopathy on chest radiographs. We present a case of AVAs found during evaluation of chest pain in a patient who was also found to have pulmonary thromboembolism. The mass was worked up with cross sectional imaging techniques using both Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) and ultimately Positron Emission Tomography (PET). Due to recurrent symptomatology, the aneurysm was coiled. [ABSTRACT FROM AUTHOR]

Although a popliteal venous aneurysm is a rare entity, it is an important cause of pulmonary embolism (PE), which is occasionally life-threatening. We herein report a case of a popliteal venous aneurysm with deep venous thrombosis (DVT) in the contralateral calf. A 65-year-old male, who presented with sudden onset palpitation and dyspnea, was transferred to our hospital. Enhanced computed tomography revealed PE and a venous aneurysm of the left popliteal vein. The popliteal venous aneurysm was saccular and had an intramural thrombus. Furthermore, duplex scanning detected DVT in the contralateral calf. The patient underwent a tangential aneurysmectomy with lateral venorraphy. The surgery and postoperative course were uneventful. The PE and calf DVT disappeared with perioperative anticoagulant therapy. It is recommended that, in the treatment of popliteal venous aneurysms, special attention should be given to the condition of the venous vessels of the contralateral leg, because this can influence the therapeutic strategy. [ABSTRACT FROM AUTHOR]

Popliteal venous aneurysms have always been linked to death from pulmonary embolism. Incidental finding of an asymptomatic popliteal venous aneurysm during duplex scan performed for patients with chronic venous disease is increasingly diagnosed but the relation between popliteal venous aneurysms and chronic venous disease remains unknown. We report the incidental finding of three asymptomatic popliteal venous aneurysms associated with iliac vein compression in patients with chronic venous disease who had undergone computed tomography venography with direct pedal contrast injection. An association between popliteal venous aneurysms and iliac vein compression is postulated. [ABSTRACT FROM PUBLISHER]

Superficial venous aneurysms are rarely described and they may remain indolent or become the source for pulmonary emboli. A system of classification and treatment protocol according to size and location is proposed. Three hundred thirty patients were evaluated for symptomatic venous disease (C2-C6) over a 2-year period. A proposed designation for venous aneurysm is described. Patients fulfilling this criterion are described in reference to site of involvement, histologic findings, and method of treatment. Five percent of patients met the criteria for venous aneurysm. Nine aneurysms of the greater saphenous vein were identified. Three aneurysms were proximal to the subterminal valve and the rest were distal. Six aneurysms of the anterior accessory greater saphenous vein (AAGSV) were identified. Three aneurysms of the AAGSV spontaneously thrombosed. Two patients presented with aneurysms of the small saphenous vein. Histology revealed thickened intima, smooth muscle and adventitia. Aneurysm designation relates to diameter of normal and contiguous vein. All superficial venous aneurysms in close proximity to the junction of the femoral or popliteal vein should be ligated. Classification of venous aneurysms should include the AAGSV, which may present with spontaneous thrombosis. [ABSTRACT FROM AUTHOR]

Venous aneurysms are rare clinical entities, particularly in children, and their presentation and natural history often depend on the anatomical location and underlying etiology. We present a single case of a 12-year-old girl who presented with a palpable right supraclavicular mass. Imaging evaluation with CT, conventional venography, MRI and sonography revealed a large fusiform subclavian vein aneurysm with an unusual, mass-like fibrofatty component incorporated into the vessel wall. The girl ultimately required complete resection of the right subclavian vein with placement of a synthetic interposition graft. This case provides a radiology/pathology correlation of an entity that has not previously been described as well as an example of the utility of multiple imaging modalities to aid diagnosis and preoperative planning. [ABSTRACT FROM AUTHOR]

The popliteal vein is the most frequent site of venous aneurysm. Surgical treatment is indicated above a 2.5 cm diameter to prevent complications, notably deep venous thrombosis and pulmonary embolism (PE). Here we report a case of recurrent episodes of severe PE, leading to cardio-circulatory shock caused by a popliteal vein aneurysm (PVA) despite oral anticoagulant therapy. When surgical correction of the aneurysm was performed, we found an ulcerative lesion in the inner aspect of the vein that was acting as a 'thrombogenic focus' inside the aneurysm. An accurate inspection of the intimal wall is always important during surgery of PVA, particularly when tangential resection is performed. [ABSTRACT FROM AUTHOR]

Objective: To describe a case of a rare type of venous aneurysm (posterior tibial) with associated pulmonary embolus. We will discuss options and considerations germane to the diagnostic evaluation and possible interventions for this challenging clinical scenario. Methods: Case presentation and literature review. Results: A 36-year-old man presented to an outside hospital with a three-day history of left calf pain, acute shortness of breath and syncope elicited by exercise. Work-up demonstrated a pulmonary embolus and a posterior tibial venous aneurysm with mural thrombus. The patient presented to us 18 months later with persistent calf pain seeking an alternative to recommendations of lifelong anticoagulation. The patient was treated with surgical resection of the venous aneurysm with subsequent discontinuation of his anticoagulation. There were no surgical or thrombotic complications of this treatment course and the patient's discomfort improved. Conclusion: Primary aneurysms of the tibial veins as a cause of pulmonary emboli are rare. A review of the literature suggests that anticoagulation alone does not provide effective amelioration of thromboembolic risk from lower extremity venous aneurysms. We have reported a case of successful surgical treatment of a posterior tibial venous aneurysm and recommend that surgical correction be strongly considered for accessible venous aneurysms.

Aneurysms of the major veins are rare, and those involving the inferior vena cava (IVC) are extremely rare. The etiology of IVC aneurysms remains unknown, and they can have variable presentation. Although many aneurysms are found incidentally, others are diagnosed after complications develop. Thrombosis is a frequent presentation, and serious sequelae, such as lethal pulmonary embolism and Budd-Chiari syndrome, may result. Therapeutic alternatives range from watchful waiting to surgical management. Development of complications such as rupture has been described and may require surgery. In this article, we report the discovery of an IVC aneurysm in a patient who had chronic renal failure associated with renal hypoperfusion and severe cardiac insufficiency. [ABSTRACT FROM AUTHOR]

We describe the case of a 59-year-old female presenting with a disabling pulsatile tinnitus caused by a venous aneurysm of the sigmoid sinus. This is the first successful case of sole stenting, using a closed-cell design in the central part of the stent, leading to the occlusion of the aneurysm and the cure of the tinnitus. Venous aneurysms of the dural sinuses are rare causes of pulsatile tinnitus and the sole stenting technique provides a simpler, safe, and effective approach. [ABSTRACT FROM PUBLISHER]

Pulsatile tinnitus is a rare yet potentially disabling symptom that can have either vascular or non vascular etiologies. A recently described vascular cause is an aneurysm of dural venous sinuses. To our knowledge, eight of such cases have been published, five of which were treated surgically and three by endovascular approach. We describe one additional case treated successfully by endovascular coiling and review the current data on this subject. [ABSTRACT FROM AUTHOR]

Venous aneurysm or varix at the venous side of the fistula commonly exist in dural arteriovenous fistula (DAVF) of the anterior cranial fossa, which may be initially mistaken with aneurysm on computed tomography and magnetic resonance imaging, but always identified by angiography. We report a very unusual case of anterior cranial fossa DAVF angiographically mimicking an anterior ethmoidal artery aneurysm, which was ultimately corrected by surgery. A 41-year-old male presented with right frontal intraparenchymal hematoma with intraventricular extension. Angiography revealed a vascular lesion adjacent to the anterior fossa mimicking an anterior ethmoidal artery aneurysm, which was surgically proven to be a partially thrombosed venous varix of drainaging vein originated from the cribriform plate. A diagnosis of anterior cranial fossa DAVF was made, and venous varix was excised. Follow-up angiography after the operation revealed complete disappearance of the lesion. Our case illustrates a unique occasion that a proximal venous varix without obvious outflow angiographically in DAVF might be mistaken with an aneurysm. [ABSTRACT FROM AUTHOR]

Background: Isolated giant cerebral varix (IGV) is an uncommon vascular lesion that represents a diagnostic challenge and requires dynamic vascular studies for its characterization. The IGV is considered a benign, low-flow venous lesion with very low risk of bleeding that might cause secondary symptoms mainly due to compression of the adjacent parenchyma. Case Description: A 12-year-old female patient with non-contributory medical history presented with headache for the last 2 months. Upon admission, her neurological examination was unremarkable. Magnetic resonance imaging (MRI) and computed tomography angiography (CTA) images demonstrated a large varicose dilation of the superficial Sylvian vein, located anterior to the left temporal pole, with no evidence of abnormal arteriovenous connections or tumoral lesions. This finding was considered incidental and unrelated to her symptoms. In this case, we considered that the combination of CTA and MRIs was enough to establish an accurate diagnosis, excluding the need to perform invasive imaging studies. Taking into account these considerations, the patient was managed with conservative treatment and has been followed up for 1 year, remaining asymptomatic. Conclusion: Cerebral IGVs are rare vascular lesions that are treated conservatively when asymptomatic and surgically in the case of rupture or compression of adjacent structures. Given our observation of a high unlikelihood of vascular connections to arteries, and the information obtained with noninvasive imaging techniques such as CTA and MRI was enough to make a clinical decision and avoid the evaluation with invasive procedures.

Venous aneurysm can be classified into superficial or deep and secondary or primary. The aim of this study was to introduce primary venous aneurysm of the superficial venous system and to report the experiences treating it with sclerotherapy. A retrospective study with 120 cases of venous dilatation detects 4 patients. The clinical features, histopathology, and radiological findings were investigated. In 2 patients, sclerotherapy was performed. The patients had an asymptomatic, soft subcutaneous mass on the extremities or neck for 5.2 years on an average. Color duplex scanning showed a well-defined anechoic cystic structure with no arterial flow. Histopathologically, normal vein wall with varying degrees of thinning was observed. The patients who underwent sclerotherapy were treated successfully with no recurrence. Primary venous aneurysm of the superficial venous system should be included in the differential diagnosis of subcutaneous mass. In addition, it may be simply and effectively treated with sclerotherapy. [ABSTRACT FROM AUTHOR]

Aneurysms of the inferior vena cava (IVC) are extremely rare. To the best of our knowledge, only 29 cases of IVC aneurysms are published in literature. We present a new case of surgically treated symptomatic saccular aneurysm of the infrarenal IVC and review previously published cases. Following resection of the aneurysm and the thrombosed infrarenal IVC, the patient fully recovered. Thrombosed IVC aneurysm may mimic a retroperitoneal tumour. In some cases, CT and MRI findings may be equivocal. Surgical treatment is indicated in all symptomatic and low-risk asymptomatic cases. [ABSTRACT FROM AUTHOR]

Venous aneurysms of the superior mesenteric vein and portal vein are an uncommon occurrence and often an incidental finding. They can also be associated with hepatocellular disease and portal hypertension. We present CT and ultrasound findings of these entities. The management of venous aneurysms is generally conservative with serial imaging. [ABSTRACT FROM AUTHOR]

Portal vein aneurysm is a rare clinical entity, with only 41 published cases in the English-language literature. Twenty-five of them were congenital. We present the case of a 50-year-old woman who was incidentally diagnosed with a congenital extrahepatic portal vein aneurysm during an investigation for dyspepsia. Ultrasonographic features are described with correlation of computed tomographic and magnetic resonance findings. Etiology, clinical significance, and management strategies for these lesions are discussed and a review of the literature regarding this entity is presented. [ABSTRACT FROM AUTHOR]
