Abstract

Thoracic aortic surgery often causes massive bleeding due to coagulopathy. Hypofibrinogenemia is one of the major causative factors, but the utility of the intraoperative administration of fibrinogen concentrate has not yet been proven. The aim of this study was to estimate incidence of hypofibrinogenemia and to evaluate efficacy of using fibrinogen concentrate intraoperatively. The perioperative serum fibrinogen levels (SFL) had routinely been measured in consecutive 216 thoracic aortic surgeries performed from 2010 to 2012. Fibrinogen concentrate was principally used for hypofibrinogenemia (< 150 mg/dl of SFL) at cardiopulmonary bypass (CPB) termination. The patients who received fibrinogen concentrate (FIB group) were compared with the patients who did not received (non Fib group). There were 147 patients (68%) in FIB group at a dose of 5.5±3.5 g. The SFL were dramatically decreased with values of 164±71 mg/dl at CPB termination, compared to the preoperative SFL of 352±131 mg/dl. In the FIB group, the intraoperative and postoperative SFLs were 139±53 and 262±75 (mg/dl), respectively. Thus the SFL was recovered quickly by the administration. 110 cases (51%) showed hypofibrinogenemia at the termination of CPB. The predictors o...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
