Аннотация
During the last 9 years, aortic root preservation using gelatin-resorcin-formalin (GRF) glue was performed in 63 patients as a part of surgery for acute type A aortic dissection. Residual aortic regurgitation (AR) was evaluated, grading 0 to IV+ by echocardiography. The survival and root reoperation-free rates were also assessed. The operative mortality was 9.5% (6 patients). Early postoperative AR < or = I+, = II+ and > or =III+ were 93, 7 and 0%, respectively. Late postoperative AR > or =III+ was observed in 4 patients. Root reoperation was performed in 4 patients (7.0%). In a case of reoperation, medial degeneration was found in the aortic wall, suggesting toxic effect of GRF glue. The actuarial survival and root reoperation-free rates at 9 years were 73 and 80%, respectively. In conclusion, aortic root preservation with the proper use of GRF glue has long-term durability with very low adverse effect.
