A single-centre experience of 200 consecutive unselected patients in percutaneous EVAR.

Purpose: This study evaluated the feasibility and safety of percutaneous endovascular aneurysm repair (P-EVAR) in an "unselected" population of patients using Prostar XL closure device, comparing our results with the literature data reported for open EVAR (O-EVAR) and P-EVAR in selected populations.

Materials And Methods: We prospectively enrolled 200 patients with abdominal aortic aneurysms to be treated with the P-EVAR procedure, without any selection criteria. Four hundred percutaneous femoral accesses using the Prostar XL closure device were performed.

[Rescue endovascular revascularization in two patients with bilateral atherosclerotic renal artery occlusion].

Renal artery stenosis is found in 2% and 40% of general and high cardiovascular risk populations, respectively. Atherosclerotic renal artery stenosis (ARAS) has become an increasingly recognized clinical condition, especially in older or otherwise atherosclerosis-prone populations. This increase in prevalence has led to a dramatically increased use of percutaneous transluminal renal angioplasty.

Fibromuscular dysplasia of renal arteries presenting with bilateral renal infarction in a young man.

Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report the case of a previously healthy 43-year-old white man presenting with acute bilateral flank pain. The pain was more severe on the left side.

[Occlusion of hemodialysis vascular accesses by means of endovascular procedures].

Correct management of complications is crucial to the long-term survival of vascular access for hemodialysis. The present work report our experience with endovascular procedures in the occlusion of complicated arteriovenous fistulas (AVFs) and grafts in patients with a high surgical risk. Among the endovascular procedures carried out between January 2003 and December 2006, all those regarding the occlusion of vascular accesses by means of embolization or exclusion were selected retrospectively.

Endovenous laser therapy of the incompetent great saphenous vein.

Purpose: The aim of this study was the development of a new, even less invasive technique, for the treatment of varicose veins of the lower limbs than traditional surgery (ligation with stripping of the saphenous vein).

Materials And Methods: The new interventional radiological procedure uses the 810- to 980-nm endovascular laser fibre proposed by Min et al. Our technique involves the superselective catheterisation of the great saphenous vein under fluoroscopy with contralateral venous access achieved by performing iliac crossover.

Contrast-enhanced magnetic resonance angiography MoBI-trak in the study of peripheral vascular disease.

Purpose: To evaluate the diagnostic accuracy of contrast-enhanced magnetic resonance angiography (CE-MRA) MoBI-trak of peripheral vessels in patients with peripheral vascular disease who were candidates for digital subtraction angiography (DSA).

Methods: Eleven patients underwent CE-MRA with automated table movement (MoBI-trak) using a 1.5 T superconducting magnet (Philips Gyroscan ACS NT) equipped with a Power Trak 6000 gradient.

[Percutaneous mechanical revascularization of chronic iliac artery occlusion with "first intention" stent placement].

Introduction: Percutaneous treatment of chronic iliac artery occlusion has not yet gained complete acceptance as the method of choice. The reason of this widespread skepticism are the poor results achieved with angioplasty and/or lysis therapy. The introduction of stents seems to open new perspectives to percutaneous treatment and the latest follow-up studies report encouraging results.

[Intra-arterial digital angiography using a trans-humeral approach in the assessment of ambulatory patients].

The authors report their experience with intraarterial digital subtraction angiography (DSA) performed on outpatients via brachial artery catheterization. A total of 120 outpatients were studied for cerebral and lower limbs vascular diseases. Transbrachial catheterization was performed with 5F or, preferably, with 4F angiographic catheters.

[ERCP in the diagnosis of bilio-pancreatic pathology. Comparison with echography and CT].

The authors have evaluated both sensitivity and specificity of ERCP in comparison with other imaging methods, such as US and CT, on the basis of a study of 63 patients with suspected pancreatobiliary pathologies. Our results show ERCP of chronic pancreatitis to have 83% sensitivity and 66% specificity. As for biliary pathologies, sensitivity was 94% and specificity 88%.
