SummaryAim: This study is intended to evaluate indications for antithrombotic therapy in patients with tangentially resected popliteal vein aneurysm.Methods: Evaluation of the course of therapy in a patient with popliteal vein aneurysm. Literature review covered literature data published within the last decade. Studies were identified by searching Medline and PubMed databases for the following phrases: ”popliteal venous aneurysm” and ”popliteal vein aneurysm”.Results: The case study and literature review revealed that thromboembolic risk cannot be entirely eliminated by means of tangential resection of popliteal vein aneurysm. Vein suture and residual postoperative dilatation of the popliteal vein can be considered predisposing factors to thromboembolic complications.Conclusion: Patients with tangentially resected popliteal vein aneurysm involving vein suture can be administered oral antithrombotic therapy within three months postoperatively. Therapy extension should be made conditional on the degree of vein dilation reduction. Where the diameter at surgical site is larger than 20 mm, it appears appropriate to continue antithrombotic therapy and to repeat assessment in six months time.

Background Venous thromboembolism (VTE) may present acutely as pulmonary embolism (PE), and its late complications include chronic thromboembolic pulmonary hypertension (CTEPH). PEs may arise from thrombi originating in a venous aneurysm, in rare cases of the popliteal vein. Case Presentation A 77-year-old woman was referred to our hospital due to respiratory distress. Computed tomography revealed pulmonary thrombi and a thrombus in a popliteal vein aneurysm (PVA); PE was diagnosed. After 3 months of anticoagulant therapy (rivaroxaban), her pulmonary hypertension showed little improvement. She underwent perfusion scintigraphy, which showed multiple perfusion defects, and Swan–Ganz catheterization. Mean pulmonary artery pressure was 26 mmHg. Pulmonary angiography revealed organized distal thrombi. Based on these findings, we diagnosed CTEPH due to recurrent formation of thrombi in the PVA. Conclusion Asymptomatic PVA can lead silently to PE and CTEPH. The possibility of asymptomatic recurrent VTE should be considered in patients with pulmonary hypertension and PVA.

“…6 After diagnosis, surgical correction is mandatory if the diameter is greater than 2.5 cm, 1 -6 otherwise there is the risk of PE recurrence despite oral anticoagulation, as shown in our case as well as in other reports. 7 Tangential aneurysmectomy or venous graft interposition and aneurysm resection are always to be preferred to simple ligature as this may lead to vein insufficiency. 1 In the case we described there was no clear explanation for the presence of the vein wall ulcer: the patient did not report limb trauma and, during the operation, we did not find popliteal entrapments.…”

Recurrent pulmonary embolism secondary to popliteal vein aneurysm with intraluminal wall ulcer

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.
