Extensive Operation as One of the Solution for Patients with the Insufficient Proximal Landing Zone for TEVAR in Aortic Dissection - short term results.

Abstract

OBJECTIVE:

In our study we wanted to showed the safety, feasibility, efficacy and way how to solve the problems of endovascular repair for aortic dissection with insufficient proximal Landing Zone.

METHODS:

The clinical data of all the patients with insufficient proximal Landing Zone (PLZ) for endovascular repair for aortic aneurism and dissection Stanford type B for the period from October 2013 to June 2014 was prospectively reviewed. According to the classification proposed by Mitchell et al, aortic Zone 0 was involved in 3 cases, Zone 1 in 1 case, Zone 2 in 9 cases and Zone 3 in 6 cases (19 patients in total). A hybrid surgical procedure of supraortic debranching and revascularization, with direct anastomosed truncus brachiocephalicus and left common carotid artery, were performed to obtain an adequate aortic PLZ. Revascularization of the left subclavian artery was carried out on the patient with dissection Stanford type B and short PLZ 2.

RESULTS:

There was no significant difference of risk factors between Zone 0, Zone 1, and Zone 2 (Table 1.), but the length of the PLZ significantly differed between groups (p<0.01) and there is no significant difference in technical and clinical success rate among the groups.

CONCLUSION:

The procedure of extending insufficient PLZ for endovascular repair for aortic arch pathology is feasible and relatively safe. The TEVAR applicability in such aortic disorders could be extended.
