Combination therapy with warfarin plus clopidogrel improves outcomes in femoropopliteal bypass surgery patients
Background: Patients having undergone femoropopliteal bypass surgery remain at significant risk of graft failure. Although antithrombotic therapy is of paramount importance in these patients, the effect of oral anticoagulation therapy (OAT) on outcomes remains unresolved. We performed a randomized, prospective study to assess the impact of OAT plus clopidogrel vs dual antiplatelet therapy on peripheral vascular and systemic cardiovascular outcomes in patients who had undergone femoropopliteal bypass surgery. Methods: Three hundred forty-one patients who had undergone femoropopliteal surgery were enrolled and randomized: 173 patients received clopidogrel 75 mg/d plus OAT with warfarin (C + OAT), and 168 patients received dual antiplatelet therapy with clopidogrel 75 mg/d plus aspirin 100 mg/d (C + acetylsalicylic acid [ASA]). Study end points were graft patency and the occurrence of severe peripheral arterial ischemia, and the incidence of bleeding episodes. Results: Follow-up ranged from 4 to 9 years. The graft patency rate and the freedom from severe peripheral arterial ischemia was significantly higher in C + OAT group than in C + ASA group (P =.026 and.044, respectively, Cox-Mantel test). The linearized incidence of minor bleeding complications was significantly higher in C + OAT group than in C + ASA group (2.85% patient-years vs 1.37% patient-years; P =.03). The incidence of major adverse cardiovascular events, including mortality, was found to be similar (P =.34) for both study groups. Conclusions: In patients who have undergone femoropopliteal vascular surgery, combination therapy with clopidogrel plus warfarin is more effective than dual antiplatelet therapy in increasing graft patency and in reducing severe peripheral ischemia. These improvements are obtained at the expenses of an increase in the rate of minor anticoagulation-related complications. © 2012 Society for Vascular Surgery

Ischaemic heart disease and peripheral arterial disease: Routinely coronary angiography as strategy to reduce global risk
Atherosclerotic change in extracoronary arteries (i.e. thoracic and abdominal aorta, and carotid and femoral arteries) are associated with the extent of coronary atherosclerosis. The incidence of coronary artery disease and the clinical outcome of 163 consecutive patients affected with peripheral arterial disease (PAD), all subjected to coronary angiography, were determined in a prospective observational study. Forty patients (24.5%) were found to have significant coronary atherosclerotic disease (CAD) with a normal exercise ECG test and/or dipyridamole-thallium scintigraphy. The overall rate of myocardial revascularization observed was 56.4%, with a perioperative mortality rate (30 days) of 3.6%. Wide consensus exists on considering PAD as a CAD equivalent: patients are currently under-treated with regard to atherosclerotic risk factor modification and surgical treatment. Cardiovascular physicians should assume a more proactive clinical role in encouraging a correct therapeutic approach to the treatment of arterial diseases affecting multiple vascular beds, including extensive coronary angiography. © 2007 Pharma Project Group srl

MAJOR COMPLICATIONS FOLLOWING ENDOVASCULAR SURGERY OF DESCENDING THORACIC AORTA
We evaluated the impact of major complications on clinical outcome in a series of patients undergoing endovascular repair (EVAR) of descending thoracic aorta. From March 2001 to June 2005, 51 patients underwent EVAR for descending aortic diseases. Thirty-five were treated in emergency (60.7%) and 41 (80.4%) were in III-IV ASA class. There were no deaths, surgical conversion or paraplegia. A neurologic complication occurred in one patient (1.9%). Eleven major systemic complications occurred in 5 patients. One patient showed a primary type I endoleak at discharge, resolved spontaneously after 9 months. Three (5.9%) vascular injuries occurred during the endovascular procedure, requiring an emergency rescue iliac-femoral artery bypass. At follow-up (29\uc2\ub114 months), there was an overall mortality rate of 5.1% (3/51); 2 deaths (3.9%) were procedure related. Two secondary EVARs (3.9%) were successfully performed, one for a late type I endoleak six months after EVAR in a traumatic patient, and a second for a late rupture distally to the stent-graft implanted 36 months before in an acute type-B dissected patient. EVAR for descending aortic diseases is associated with decreased mortality and complications, however, long-term follow-up and additional studies are mandatory to detect late failure and to confirm clinical safety of this procedure. \uc2\ua9 2006 Published by European Association for Cardio-Thoracic Surgery.
