[Surgical treatment of acute aortic dissections--a clinical study using a ringed intraluminal graft].
From 1984 to 1994, surgery was performed using a ringed intraluminal graft (RIG) in 75 patients with acute aortic dissection (DeBakey's type I in 37 cases, type II in 10 cases and type III in 28 cases). The operative death rate was 24% for type I, 30% for type II and 21% for type III. The average time from onset to surgery was short (47 +/- 67 hours for type I, 34 +/- 36 hours for type II and 47 +/- 77 hours for type III). The outcome of these cases indicated that this technique was effective for saving the lives of patients in the acute early stage of aortic dissection. No characteristic complications developed after this surgery. The postoperative course of patients was followed by using CT scans, MRI, angiography. No patients developed aneurysmal formation in the ligated area or dislocation of the RIG. There were no deaths directly attributable to the RIG. Patients who were autopsied in the late postoperative period showed no aneurysm of the ligated area or necrosis of the aortic wall. In conclusion, RIG surgery effectively saved the life of patients with acute aortic dissection and the RIG could be used as prosthetic graft for long-term periods.
