Abstract
During transluminal dilation of the iliac artery, occlusion resulting from dissection occurred in four patients. In all four, the deteriorating clinical findings prompted surgical intervention. In three patients, Fogarty balloon catheters easily passed the occluded segments and specimens much the same as surgical endarterectomy specimens were retrieved. A clamp was used to retrieve the dissected portion of the vessel wall in the fourth patient. Three of four vessels have remained patent for 18 months, 18 months, and 6 months, respectively. One patient underwent bypass surgery 4 months after the occlusion episode for recurrent stenosis in a segment of vessel above the occluded segment, which had also been dilated during the same procedure. It is therefore possible in some cases to salvage vessels occluded during angioplasty, making it unnecessary to resort to aortofemoral or other type of bypass.
