[The endovascular repair of aortic dissection: early clinical results of 178 cases].
OBJECTIVE
To discuss the safety, feasibility, efficacy and problems of endovascular repair for aortic dissection.


METHODS
From June, 1998 to Dec, 2004, 178 aortic dissections were treated by stent-grafts, including 76 acute cases and 102 chronic cases, 19 cases with Stanford A and 159 cases with Stanford B. Under local or general anesthesia, every stent-graft was deployed at the proper position of first tear entry through femoral artery under X-ray fluoroscopic. The changes of hemodynamic in true and false lumen, visceral and limbs blood supply were investigated after operation.


RESULTS
10 cases combined with left common carotid artery or left subclavian artery or hepatic artery and superior mesenteric artery bypass. 36 left subclavian arteries were covered simultaneously without bypass and the average blood pressure of left brachial artery was (61.6 +/- 23.7) mm Hg. The stent-grafts were deployed above thoracic 8 in 159 cases and below thoracic 8 in 19 cases. This group included 3.4% 30-day death rate, 12.9% endoleak rate after deployment, and without misplace of stent grafts, migration, rupture, conversion to open surgery and paraplegia complication. The average operation time 1.5 h (0.5-4.3 h), blood loss 140 ml (30-500 ml), movement recover time 1.8 d (0.5-21.0 d), food recover time 1.5 d (0.5-9.0 d). The true lumen blood supply in most of damaged visceral arteries were improved. Follow up between 1 month to 76 months, the endoleak rate was 6.4% one month later.


CONCLUSIONS
The endovascular repair is a safe, efficacy and feasible method to aortic dissection. The long term results keep in follow up.
