A Case of Popliteal Venous Aneurysm Diagnosed after Sudden Cardiac Arrest.

A popliteal venous aneurysm (PVA) is a rare vascular disorder. We report a case of PVA discovered through further evaluation of sudden cardiac arrest (CA) caused by a pulmonary embolism (PE). It is well-known that PVA causes PE; however, there are few reports of PVA causing CA. A tangential aneurysmectomy and lateral venorrhaphy were performed. The patient's postoperative course was uneventful. When contrast-enhanced computed tomography is performed to search for the cause of CA, PVA should be considered and thus, screening below the knee is recommended. At 1-year follow-up, there were no complications.

Massive pulmonary thrombosis caused by a popliteal venous aneurysm: A case report.

A venous aneurysm is characterized by a localized dilated lesion in most major veins. Popliteal venous aneurysms (PVAs) are rare; however, they are one of the causes of deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE), which can be critical due to the high mortality risk. We present a 21-year-old woman without prior medical history, who arrived by ambulance after having a transient cardio-pulmonary arrest. Contrast computed tomography revealed a massive PTE and a right PVA with a thrombus. Laboratory data suggested that she had no thrombotic predisposition. Therefore, we diagnosed her condition as a massive PTE that derived from a thrombus, which arose from the right PVA. After successful intravenous thrombolysis of the PTE and DVT, surgical plication of the right PVA was performed to prevent the recurrence of PTE. She has had no recurrence of PTE or DVT two years after surgical treatment. This case suggests that surgical plication might be an effective way of preventing recurrence in patients with PVA. Learning objective: Popliteal venous aneurysm (PVA) occurrence is rare, but it can result in deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE). To treat our patient who suffered transient cardiac-pulmonary arrest caused by a massive PTE, we first used a recombinant tissue plasminogen activator and anticoagulant therapy. After the condition was stabilized, surgical plication of the right PVA was performed to prevent DVT recurrence. The present case suggests that surgical plication might be beneficial.

Surgical Treatment of a Giant Popliteal Venous Aneurysm and Arteriovenous Fistula on the Adjacent Femoral Vein and Its Postoperative Findings.

A case of a giant popliteal venous aneurysm that caused massive pulmonary thromboembolism with an arteriovenous fistula draining into the adjacent proximal femoral vein is reported herein. Deep veins in the lower leg were occluded by thrombi. The inlet and outlet orifice inside the aneurysm was closed and aneurysmorraphy was performed. The fistula was retained on the estimation that it would maintain the blood flow and prevent thrombus formation inside the femoral vein. The aneurysm was shrunk, the femoral vein was patent, and the fistula was not observed 1 year later, although it still existed 1 week after the operation.

A Surgical Experience of Popliteal Venous Aneurysm Associated with Acute Pulmonary Thromboembolism / 日本心臓血管外科学会雑誌

Popliteal venous aneurysm (PVA) is recognized as source of fatal pulmonary embolism ; surgical treatment is indicated. A 79-year-old woman presented with acute shortness of breath. A cardiac ultrasound echography showed right heart overload and pulmonary hypertension. A contrast enhanced CT revealed multiple pulmonary artery emboli and right popliteal venous aneurysm. She was immediately started anticoagulation therapy with oral factor Xa inhibitor and her dyspnea improved. As thrombus in venous aneurysm was considered the cause of the pulmonary embolism, we recommended surgical treatment. Tangential aneurysmectomy with lateral venorrhaphy for the saccular venous aneurysm was performed. Postoperative contrast enhanced CT showed good morphology and she was discharged without complication. Surgical treatment of symptomatic popliteal venous aneurysm is considered useful strategy.

Popliteal Venous Aneurysm With Pulmonary Embolism: A Case Report.

Popliteal venous aneurysm (PVA) is defined as an increase in the diameter of the popliteal vein, twice its normal dimension. Herein, we report a case of right PVA with severe pulmonary embolism in a 75-year-old woman who presented with sudden chest tightness and dyspnea. Clinical examination revealed hypotension and hypoxemia. Radiographic investigations revealed extensive pulmonary embolism and right fusiform PVA. Following thrombolysis, her blood pressure and oxygen saturation normalized. However, she developed right calf swelling, and angiography revealed a thrombus in the right PVA, which was managed by catheter-directed thrombolysis. Thereafter, a vascular bypass was performed using the left great saphenous vein as a conduit to treat recurrent thrombosis. Subsequent venography indicated a patent vein graft, acceptable blood flow velocity, no thrombosis residue, and no significant thrombosis. Follow-ups at 3, 6, and 12 months revealed satisfactory outcomes. In conclusion, if the systemic condition is conducive, a surgical resection and reconstruction of the popliteal vein is recommended for the treatment of PVAs.

Popliteal Venous Aneurysm and Pulmonary Embolism Initially Presenting with Recurrent Pre-syncope: A Case Report.

INTRODUCTION: Popliteal venous aneurysm (PVA) can lead to recurrent pulmonary embolism (PE) and therefore necessitates prompt diagnosis and treatment. PVAs are often asymptomatic, and their most common symptoms are associated with thrombosis. The clinical presentation of PVAs varies from asymptomatic to PE induced cardiopulmonary arrest, but there are few reports of cases initially presenting with transient impairment of consciousness. REPORT: A 75 year old man was referred with recurrent episodes of pre-syncope. He had normal vital signs and oxygen saturations, and his electrocardiogram was normal. Detailed interview revealed that the patient had suffered from calf pain and swelling before visiting the clinic. Therefore, an evaluation for deep venous thrombosis and PE was conducted. Lower limb ultrasound revealed an enlarged popliteal vein, measuring 20 mm in diameter, with a spontaneous echo contrast. Enhanced computed tomography showed peripheral pulmonary artery embolism. The patient was diagnosed with PE secondary to PVA. An inferior vena cava filter was inserted, followed by tangential aneurysmectomy and lateral venorrhaphy; apixaban 10 mg/day was initiated on post-operative day 1. The filter was removed one week after the surgery, and the patient remained symptom free on completion of treatment and did not complain of any symptoms such as pre-syncope. DISCUSSION: This patient with PVA presented with the initial symptoms of repeated pre-syncopal episodes that were attributed to recurrent PE caused by thrombi from a PVA. Complete symptom resolution was obtained by inferior vena cava filter placement, PVA surgery, and post-operative anticoagulation. Transient consciousness disorders such as pre-syncope can be the initial symptoms of PVA and PE.

Diagnostic Dilemma of Recurrent Pulmonary Embolism.

Popliteal venous aneurysms are rare vascular disorders associated with a high risk of pulmonary embolism. We present the case of a 56-year-old woman hospitalized for a third episode of unprovoked pulmonary embolism. Venous ultrasonography identified a popliteal aneurysm, repeatedly missed by two-point compression venous ultrasonography, which was eventually confirmed by a magnetic resonance examination. Because of its highly symptomatic nature despite optimal anticoagulant treatment, the decision was made to undergo surgery, consisting of aneurysmectomy followed by patch angioplasty. The goal of this paper is to report a rare case of popliteal venous aneurysm and its treatment strategies and postoperative evolution.

Treatment of popliteal venous aneurysms by femoral vein ligation.

Popliteal venous aneurysms are highly associated with local venous thrombosis and pulmonary embolism. We propose a simple and new surgical therapy for popliteal venous aneurysm by ligation of the femoral vein. We describe the case of a woman with recurrent pulmonary embolism. Venous ultrasound examination showed a venous aneurysm of the right popliteal fossa. We proposed a ligature-section of the femoral vein just below the confluence of the great saphenous vein. After >6 years of follow-up, the patient is asymptomatic, with a completely normal life and only a small amount of edema of the right leg.

Surgical repair for popliteal venous aneurysm causing severe or recurrent pulmonary thromboembolism: three case reports.

Poplitealvenous aneurysms (PVA) are associated with deep venous thrombosis and recurrentpulmonary thromboembolism (PE). We report three cases of PVA. In all three patients the first sign of PVA was acute PE; in one case, the PE was recurrent. Computed tomography and duplex ultrasonography revealed not only PE but also popliteal venous dilatation with thrombus. Surgical reconstruction was performed in each case after treatment for PE. No postoperative complications occurred, including recurrent PE. Surgical repair of PVA is safe and is a recommended treatment.
