          Abstract

          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.

          Presentation and management of venous aneurysms.

          Venous aneurysms have been reported to occur in most major veins. These aneurysms may be misdiagnosed as soft tissue masses or as inguinal or femoral hernias. Venous aneurysms of the deep system have been associated with deep venous thrombosis (DVT) and pulmonary embolism (PE). To more precisely characterize these lesions, we reviewed our experience with the disease. A retrospective analysis of our experience over 22 years was performed. The presentation and management of these lesions were reviewed and compared with the literature. Thirty-nine venous aneurysms were reported in 30 patients. There were 14 men and 16 women. The patients' ages ranged from 3 to 75 years. Thirty aneurysms were located in the lower extremities, four in the upper extremity, and five in the internal jugular vein. Fifty-seven percent of lower extremity aneurysms occurred in the deep system. Patients' symptoms were a mass (75%) associated with pain (67%) and swelling (42%). Thromboembolism occurred in six patients, DVT in three, and PE in three. Eight of nine patients (89%) who had aneurysms of the superficial venous system had their condition misdiagnosed. Diagnosis was made by phlebography (60%), color flow duplex scanning (27%), continuous-wave Doppler scanning (10%), or magnetic resonance imaging (10%). The aneurysm size ranged from 1.7 to 6.0 cm. Management consisted of tangential excision in five (17%), total excision in 23 (77%), and observation in seven (6%). Venous aneurysms are unusual vascular malformations that occur equally between the sexes and are seen at any age. Most patients have a painful mass of the extremity, and diagnosis is achieved by radiologic examination. Superficial venous aneurysms of the inguinal region are often misdiagnosed. Thromboembolism is more common in aneurysms involving the deep venous system. Because of their potential morbidity, management should be surgical in the majority of cases.

            Management of symptomatic and asymptomatic popliteal venous aneurysms: a retrospective analysis of 25 patients and review of the literature.

            Popliteal venous aneurysms (PVAs) are an uncommon but potentially life-threatening disease because they can be a source for pulmonary emboli (PE). With the widespread use of venous duplex scanning, PVAs are increasingly found in patients with deep or superficial vein insufficiency, and questions have arisen as to the management of these aneurysms. The purpose of this study was to review our experience in the management of PVAs diagnosed in patients with PE and in patients with chronic venous diseases. Twenty-five patients with PVAs were treated in two centers between 1985 and 1999. There were 20 women and five men, with an average age ranging from 33 to 79 years (mean age, 59 years). Twenty-four percent (6/25) presented with PE, and 76% (19/25) of PVAs were discovered during investigation for chronic venous disease (varicosities, n = 13; post-thrombotic symptoms, n = 6). The diagnosis of PVA was achieved in all cases with venous duplex scanning and phlebography. Aneurysms were located in the proximal popliteal vein (n = 17) and at the saphenopopliteal junction (n = 8). Seventy-two percent (18/25) of PVAs were saccular, and 40% (10/25) had an intraluminal thrombus. Two patients with PE underwent cardiac arrest, with one requiring a pulmonary embolectomy. The Fisher exact test showed a statistically significant correlation between PE and the presence of thrombus (50% vs 7% without thrombus, P =.02). Aneurysms were treated with tangential aneurysmectomy and lateral venorrhaphy (n = 19), resection with end-to-end anastomosis (n = 2), resection with interposition of the greater saphenous vein (n = 2) or the superficial femoral vein (n = 1), and resection with vein transposition (n = 1). Two patients who experienced a PE had an inferior vena cava filter placement before surgical repair of the PVA. Mean follow-up was 63 months (range, 11-168 months). No operative deaths occurred, and no patient had evidence of a recurrent PE. Postoperative minor complications (20%) included transient common peroneal nerve palsy (n = 2), postoperative hematoma (n = 2), and wound infection (n = 1). Postoperative thrombosis of the surgical repair occurred in three patients, and patency was restored with anticoagulation therapy. Despite its rarity, PVAs should be ruled out with venous duplex scanning in patients with PE and in patients presenting with chronic venous diseases. Because of the unpredictable risk of thromboembolic complications, surgical treatment that is accompanied by a low morbidity rate is indicated in all PVAs. Tangential aneurysmectomy with lateral venorrhaphy is the procedure of choice.

              A systematic review of venous aneurysms by anatomic location

              Venous aneurysms are uncommon vascular abnormalities that may be identified anywhere in the body. Historically, they were often misdiagnosed as soft tissue lesions, but with the advent of readily available noninvasive imaging (such as duplex ultrasound), they can now be easily identified. Our aim was to review the presentation of venous aneurysms, available imaging modalities for defining them, and management.
