One hundred six patients who underwent a total of 141 operations, on 156 limbs for peripheral arterial emboli from 1964 to 1979 were studied. The average age of the patients was 68.5 years. The source of the emboli in 76.4% of the patients was arteriosclerotic heart disease and atrial fibrillation. The presenting clinical symptoms and signs were the most accurate determinate of limb salvage. Our overall limb salvage was 86.5% and in the survivor population 93.9%. The overall hospital mortality was 21.7%. There were much higher morbidity and mortality rates associated with each subsequent embolic event. Particular attention was paid to factors related to recurrent emboli. The use of antigoagulants in the post embolectomy period does not have a statistically significant effect of preventing recurrent emboli.
A retrospective review was done of all patients undergoing surgical repair of abdominal aortic aneurysm (AAA) on whom coagulation studies were obtained. Those patients with laboratory documented disseminated intravascular coagulation (DIC) were selected and their clinical records reviewed. This included 7 patients studied in the periods 1964-1965 and January 1971-July 1973. Of these 7 cases, 4 occurred in patients undergoing emergency operation for ruptured aneurysm and 3 were in elective cases. All 7 patients exhibited clinical evidence of abnormal bleeding, while 6 of the 7 progressed rapidly to renal shutdown. The seventh patient recovered spontaneously. Of the 6 patients with full blown clinical and laboratory evidence of DIC, 2 recovered. Both cases received heparin therapy and multiple hemodialyses. A third patient was started on heparin but died at 36 hours in heart failure. All 3 patients receiving heparin showed clinical cessation of abnormal bleeding and disappearance of soluble fibrin monomer complexes within 24 hours of starting therapy. The study suggests a higher incidence of DIC than has previously been appreciated in both the emergency and elective repair of AAA. The prompt recognition and treatment of this complication may reverse the abnormal intravascular clotting, minimize its more serious results and avoid futile and dangerous operative intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
