On table fenestrated stent graft in zone 0 and zone 1 for aortic arch diseases / 中华普通外科杂志

ABSTRACT

Objective To evaluate fenestrated thoracic endovascular aortic repair (f-TEVAR) using fenestrated stent graft on table in zone 0 and zone 1 for aortic arch diseases.Methods 13 patients undergoing f-TEVAR by using physician modified fenestrated stent grafts (PMSGs) on table in zone 0 and zone 1 for aortic arch diseases between Nov 2015 and Mar 2018 were retrospectively reviewed.Results The median age was 59 years(range,33-81 years).PMSGs were deployed from Z0 in 5 patients and Z1 in remaining 8 patients.All but 3 patients underwent elective procedure.The technical success rate was 92.3％.Overall mortality was 7.7％ (1/13).There were no perioperative neurologic complications and paraplegia.One patient suffering from acute left leg ischemia and renal failure recovered after openembolectomy and dialysis.Median length of stay was 9.0 days (range,4-35 days).12 patients were survival at a median follow-up of 11.5 months (range,1.0-19.0 months).Retrograde dissection occurred in one patient and resolved after open repair.During follow up,all target vessels remained patent,with no fenestration-related type Ⅰ or Ⅲ endoleaks.Conclusions f-TEVAR using modified fenestrated stent grafts on table in Z0 and Z1 is feasible for the treatment of aortic arch diseases.
