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.
