Abstract:
Objective To investigate the influence of the hematoma involving the aortic arch in endovascular aortic repair of complicated type B intramural aortic hematoma. Methods A total of 69 patients[58men; mean age(58.1±8.9)years; range 38-77]underwent endovascular repair between February 2011 and June 2015 were retrospectively reviewed. Patients with hematoma involving about the left subclavian artery level were categorized as group A(n=28) and patients without hematoma involvement to the aortic arch were categorized as group B (n=41). Results All the patients were treated with coverd aortic stents. The success rate was 97.1％ with complete isolation of lesion in 67 patients. The average follow-up period was(19.6±14.1)months. During perioperative period, no procedure related deaths was recorded. Perioperative complications include paraplegia in 1case(1.4％) in group B and stent graft-induced new entry in 2 cases(2.9％) in group A. During the follow-up period 1 case in group A within 1 month and another 1 case in group B within 1 year developed new entries at proximal end of stents. 1 case (1.4％) in group B had asymptomatic type Ⅰ endoleak 2 years after TEVAR. Conclusions Type B aortic intramural hematoma with arch involvement is not a risk factor of stent-induced new entry in perioperative period after endovascular treatment and further studies are needed. Strict control of blood pressure is essential for the prevention of stent-related complications.
