Background: During the last ten years we diagnosed two cases of venous aneurysm. The purpose of this report was to point out a certain risk of the thrombembolism of superficial venous aneurysms and to review our experience in the management of superficial and deep venous aneurysms.Methods: The presentation and management of these lesions were reviewed and discussed together with other cases from available literature.Results: In the first case an aneurysm of lesser saphenous vein with a possible threat of thrombembolism was revealed and surgically solved with saphena resection. Ten years after the surgery she is still symptom free. In the second case a small fusiforme popliteal vein aneurysm without any evidence of mural thrombus was diagnosed. The patient was treated conservatively with regular venous duplex imaging follow up. Two years later the disease has been stable.Conclusions: Superficial venous aneurysms can have a certain risk of the thrombembolism. Since surgical therapy is very simple, it can be recommended in all cases. Nevertheless, trombembolism is more common in deep venous aneurysms, especially popliteal ones, in which surgical repair can be based on their pathological features and presentation or can be indicated in all cases.

The function of an arteriovenous (av) fistula for haemodialysis may be complicated by manifestation of peripheral venous hypertension, which results from the arterial blood flow through the venous system into the periphery of the upper extremity. Its development is most typically caused by a proximal forearm av-fistula, as, in addition to the desirable arterialisation of the subcutaneous venous system of the arm, arterialisation of the venous system of the forearm and the hand may occur and possibly promote the development of venous hypertension, which may in the extreme result in gangrene of the fingers. Awareness of these problems as well as of the necessity of their surgical solution is essential for doctors dealing with haemodialysis.

The authors describe treatment possibility for AAA with renal arteries arising from aneurysmal sac in high operating risk patients. They combined endovascular stent-grafting for aneurysmal sac exclusion and classical vascular surgical iliacrenal bypass for revascularisation of excluded renal arteries.
