Outcomes of thoracic endovascular aortic repair with physician-manufactured partial micropore stent grafts for aortic arch pathologies

Objective Thoracic endovascular aortic repair has been extensively utilized in the management of thoracic aortic diseases. Numerous efforts have been made to enhance clinical outcomes through the use of stent grafts. This study aimed to investigate the effectiveness and safety of physician-manufactured partial micropore stent grafts in thoracic endovascular aortic repair. Methods Between December 2017 and June 2022, data were collected from 56 patients who underwent thoracic endovascular aortic repair using physician-manufactured partial micropore stent grafts. The evaluation encompassed technical success, perioperative and follow-up morbidity and mortality, stroke incidence, and branch artery patency. Results In this investigation, 56 patients received treatment with physician-manufactured partial micropore stent grafts. Of these patients, 46 were male, with a mean age of 62.1 ± 11.2 years. Aortic pathologies comprised aortic dissection (n=31, 55.4%), aortic aneurysms (n=10, 17.9%), penetrating aortic ulcer (n=8, 14.3%), and intramural hematoma (n=7, 12.5%). During a median follow-up of 18 months (IQR, 13-25), the stroke rate, supra-aortic branch patency rate, and endoleak rate were 0%, 100%, and 7.1%, respectively. There were no occurrences of all-cause mortality, stroke, or the necessity for open conversion. Conclusions Thoracic endovascular aortic repair with physician-manufactured partial micropore stent grafts is a viable alternative for addressing aortic arch pathologies in proficient medical centers. The approach demonstrates favorable branch patency, a low complication rate, and minimal postoperative mortality.
