Abstract:
Objective To evaluate the feasibility,efficacy,and short to mid-term results of endovascular management of acute type B aortic dissection complicating visceral or lower limb malperfusion.Methods A retrospective study was conducted in 23 consecutive patients with acute type B dissection complicating visceral or lower limb malperfusion treated endovascularly at a single center between July 2001 to December 2012.Of the 23 patients identified [20 men,3 women; mean age (52 ±9) ranging 42-75]presented with clinical and imaging evidence of end-organ malperfusion:renal artary in 5 (21.7％),superior mesenteric artery in 9 (39.1％),celiac trunk in 3 (13％) and lower limb in 6 (20.1％),artary renal and lower limb in 2.Results All patients had stent-graft coverage of the proximal entry tear.11 (47.8％) patients needed additional branch vessel stenting.Successful correction of malperfusion was achieved in all the patients and the successful rate of operation and technology was 100％.In 1 patient,ischemia in the lower limb was resolved after a stent was implanted to the right iliac artery.In another patient,complicated with lower limb ischemic necrosis,amputation was performed after one stage stent-graft placement.The duration of follow-up was 6 months to 72 months,mean (21 ± 11)months.There was no migration of stent-graft and end-organ ischemia.No patients suffered from paraplegia in this group.Conclusions Endovascular coverage of the proximal entry tear in acute type B aortic dissections complicating end-organ malperfusion is a reasonable first line treatment.But some cases may need a combination branch vessel stenting.
