| Popis: | Objectives Open repair is still the first choice for thoraco-abdominal and para-renal aortic aneurysms, but surgical treatment is burdened by significant morbidity and mortality, especially in urgent setting. Endovascular treatment by fenestrated or branched endografts is feasible and safe; but in urgent/emergent settings, custom-made endografts are hardly available in due time, and the repair with standard multibranched devices is still debated in cases with complex anatomy. Parallel grafting, on the other hand, which exploits covered stents to preserve patency of the visceral vessels, has been shown as a valuable option and can be performed in urgency, though some concerns still remain regarding its durability and complications. The purpose of this case series is to review the outcomes of all consecutive cases of complex aortic diseases treated with this technique in emergent/urgent setting. Materials and methods All cases of endovascular aortic repair of thoraco-abdominal and para-thoraco-abdominal performed in urgency or emergency from 2016 to June 2019 were retrospectively reviewed, recording clinical records, operative technique, primary technical success, and long-term outcomes. Each patient was followed-up by computed tomography angiography three months after the procedure and yearly thereafter. Results Twenty consecutive patients (median age: 68, range: 47–89, male/female ratio: 16:4) affected by para-thoraco-abdominal (12) or thoraco-abdominal (8) were treated in urgent or emergent setting by chimney and/or periscope technique. A total number of 37 visceral vessels were stented (29 renal arteries, 1 polar artery of the kidney, 3 superior mesenteric arteries, and 4 coeliac trunks). Primary technical success was 100%, with one perioperative death. One patient died on post-operative month III for unrelated cause. Two type II endoleaks were detected at the first post-operative imaging studies and were managed conservatively. One type IB endoleak was treated by endovascular repair with a custom-made endograft (overall re-intervention rate: 5%). Over a median 22 months follow-up (range: 4–40, interquartile range: 12 months), all stentgrafts were patent. Conclusion Parallel graft is a feasible and safe option that should be considered in urgent and emergent treatment of para-thoraco-abdominal and thoraco-abdominal, when fenestrated and branched endografts cannot be used. |
