Abstract

A study was made of delayed embolectomy in 45 patients (55 limbs). In 5 patients (11%) the cause of arterial embolization was rheumatic heart disease, and 40 patients (89%) suffered from atherosclerotic cardiovascular disease. The study was divided into 3 phases: I (1960-1964), II (1965-1974) and III (1975-1981). In phases II and III surgery was carried out using the Fogarty catheter technique. In 5 patients the embolus was located in the upper extremity. Seven patients died and 8 major amputations were performed within 30 days of surgery. Use of the Fogarty catheter technique and persistent anticoagulant therapy effected 71.8% limb salvage in phase II and 91.6% limb salvage in phase III. Successful revascularization was achieved in 70.9% of the limbs in which peripheral emboli had occurred on an average of 2.7 days prior to surgical intervention. A theoretical basis for the late development of the acute embolic onset is presented.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
