Operative Technique, Paraplegia, and Mortality After Blunt Traumatic Aortic Injury

摘要: Hypothesis The use of mechanical circulatory support (MCS) during repair traumatic aortic injuries is associated with a decreased incidence postoperative paraplegia and mortality. Design Setting Historical cohort study contemporaneous but nonrandomized controls in tertiary care hospital from July 1, 1988, through December 31, 1999. Patients Interventions Consecutive cases undergoing operation for injuries. Use MCS (with or without systemic heparinization) determined by surgeon preference. Main Outcome Measures Incidence Results Twenty-two patients underwent using MCS, resulting no 4 deaths, 3 them cerebral ischemia. Thirteen had their repaired "clamp-and-sew" passive shunt technique deaths 2. Compared an earlier report our group January 1975, June 30, the annual has decreased, whereas age proportion operations have increased. A review recent literature on reveals average 1% 16% MCS. Overall mortality similar, others also reported ischemia after repair. Conclusions paraplegia. occasional occurrence deserves further study.
