We operated upon an 18-year-old female presenting a spontaneous aneurysm of the axillary vein. Pathologic examination of the aneurysm showed an anomalous muscular layer. To our knowledge, this is the first case of nontraumatic axillary venous aneurysm.
The Fogarty catheter is an invaluable tool in the surgical practice of a vascular surgeon. Arteriovenous fistula is an unusual but potentially dangerous complication of its use. We present the case of a man who suffered a peroneal arteriovenous fistula as a result of an above-knee femoropopliteal polytetrafluorethylene graft thrombectomy. As the fistula compromised the viability of the extremity, surgical correction was warranted. It was performed without further complications to the patient. The few cases reported in the literature are reviewed. We conclude that this complication should be repaired as soon as it is detected.

A patient who suffered recurrent myocardial ischaemia and cerebrovascular symptoms 56 months after a quadruple coronary bypass is reported. Three coronary arteries had been bypassed using reversed saphenous vein and the other using the left internal mammary artery (IMA). Coronary angiography demonstrated patency of al bypasses but the presence of an obstruction of the left subclavian artery proximal to the origin of the left IMA, with angiographic criteria of the steal syndrome. The patient's symptoms were relieved by bypass from the left common carotid artery to the distal left subclavian artery. The pathophysiology, diagnosis, prevention and treatment of coronary steal syndrome are discussed.
