RESUMEN
PURPOSE: The aim of this study was to evaluate the efficacy of endovascular treatment of isolated iliac artery aneurysms (IIAA) and compare our data with those reported in the literature. MATERIALS AND METHODS: From May 2005 to December 2010, 32 patients (31 men and one woman; mean age 73±12 years) with a total of 40 IIAAs underwent endovascular treatment at our institute. We evaluated technical success, long-term patency, early and late complications and overall mortality. RESULTS: At a median follow-up of 36 months, we achieved a technical success of 100%, a primary patency of 95% and a secondary patency of 100%, with complete exclusion of the aneurysm in 84.6% of cases. In 12.8% of cases, there was a reduction in aneurysm sac volume, with an incidence of type II endoleak of 12.8%. Overall survival at 1, 2, 3, and 6 years was 96.8%, 84.2%, 66.6% and 64%, respectively. CONCLUSIONS: Our study documents the effectiveness of endovascular treatment of iliac aneurysms, which has become the first-choice treatment at our institute. This finding is consistent with the most recent literature and confirms the safety and long-term patency of stent-graft placement.

PURPOSE: The authors compared the immediate, mid-term and long-term effectiveness of cryoplasty and conventional angioplasty for treating stenotic-occlusive lesions of the femoropopliteal arteries in diabetic patients. MATERIALS AND METHODS: From October 2006 to November 2009, 48 patients with non-insulin-dependent diabetes mellitus (DM) and an indication for percutaneous revascularisation of the femoropopliteal arteries were randomly assigned to treatment with angioplasty or cryoplasty. The following parameters were analysed and compared between the two groups: immediate technical success (residual stenosis <30%) and distal run-off as assessed on postprocedural angiography, and degree of restenosis and distal run-off at 6 and 12 months, as assessed with either colour Doppler ultrasound (CDUS) or digital subtraction angiography (DSA). RESULTS: Treatment with angioplasty revealed a significant superiority in procedural technical success (p=0.04), a significant reduction in the degree of restenosis at 6 months (p=0.02) and a significant increase in the distal run-off at 6 (p=0.005) and 12 (p=0.01) months. CONCLUSIONS: Conventional angioplasty is more effective than cryoplasty for treating stenotic-occlusive lesions of the femoropopliteal arteries in diabetic patients and provides better immediate, mid-term and long-term results.

The association of Moyamoya disease (MD) with other cerebrovascular disease has been reported in literature but not the occurrence of MD and arteriovenous fistula of the epiaortic vessels. A 61-year old Italian woman was admitted to our Department because of the sudden onset of Broca's aphasia. At general examination she presented a murmur above the right clavicle. Brain magnetic resonance imaging (MRI) showed an ischemic lesion involving left frontal and temporal lobes. Cerebral digital subtraction angiography (DSA) showed moyamoya vessels and an arteriovenous fistula between vertebral artery and internal giugular vein in right laterocervical region. This is the first report of the association of MD with arteriovenous fistula of the epiaortic vessels.
