Lower Extremity Revascularization Using Directional Atherectomy

Lower extremity revascularization in diabetes: late observations.

HYPOTHESIS Despite the success of infrainguinal arterial bypass in diabetic limb and foot salvage, optimism remains guarded because of purported high late mortality and limb loss in patients with diabetes. DESIGN Inception cohort, with minimum 5-year follow-up. SETTING Tertiary referral center. PATIENTS Eight hundred forty-three consecutive patients undergoing lower extremity arterial rec...

Atherectomy in treatment of lower extremity peripheral arterial disease

‘Optimal’ Directional Coronary Atherectomy

Background—Previous clinical trials of directional coronary atherectomy (DCA) have failed to show significant improvement in early or late outcomes compared with balloon angioplasty (PTCA). The present study tested the hypothesis that more aggressive “optimal” atherectomy could be performed safely to produce larger initial lumen diameters and a lower late restenosis rate. Methods and Results—Th...

Directional Coronary Atherectomy

Background. Directional coronary atherectomy has recently become available to treat coronary stenoses. This study was performed to determine the relation of patient characteristics and stenosis morphology to procedural outcome with directional coronary atherectomy to gain insight into which patients might be best treated with this device. Methods and Results. Four hundred stenoses from 378 pati...

Simultaneous hybrid revascularization for symptomatic lower extremity arterial occlusive disease

Multilevel revascularization, using a combination of endovascular and open (hybrid) surgery, is increasingly being used. Hybrid surgery allows complex anatomy to be treated by minimally invasive procedures in medically high risk patients. The aim of the present study was to report a novel hybrid surgery for lesions in the multilevel lower extremity arteries and to evaluate the clinical outcomes...
