Hybrid treatment for complex aortic problems combining surgery and stenting in the integrated operating theater.
OBJECTIVE
Conventional surgical treatment of complex aortic pathologies involving several thoracoabdominal aortic segments necessitates extended incisions or subsequent surgeries, resulting in significant mortality and morbidity rates. The combination of surgery and simultaneous stenting in the operating theater may reduce the surgical trauma.


METHODS
A total of nine patients (62 +/- 10 years, range 44-70) underwent a combined surgical and endovascular treatment of thoracic or thoracoabdominal aortic aneurysms or chronic dissection. Five patients were treated with viscero-renal artery translocation followed by transfemoral stenting of the entire thoracoabdominal aorta. Two patients underwent debranching of the supraaortic vessels followed by immediate transfemoral stenting of the aortic arch, and two patients with a history of an ascending aortic aneurysm repair were treated with open surgical debranching of the supraaortic trunks and repair of the ascending aorta and aortic arch with elephant trunk technique. Preoperatively, magnetic resonance imaging was used to check supraaortic and intracranial vessels as well as the completeness of the Circle of Willisi prior to arch stenting and/or supraaortic vessel surgery. Cerebrospinal fluid drainage and induced mild hypertension have been used for one-step thoracoabdominal aortic stenting.


RESULTS
Thirty-day mortality rate and incidence of paraplegia was 0%. There was a single reversible perioperative stroke after aortic arch stenting. One patient required temporary renal replacement therapy using continuous arterio-venous hemofiltration. There was one early reoperation at the superior mesenteric artery after viscero-renal translocation. Four type I endoleaks occurred in three patients requiring two interventions. All patients have been discharged to home.


CONCLUSIONS
The innovative combination of simultaneous conventional surgery and stenting reduces the operative burden for patients with complex aortic pathologies involving several segments of the thoracic and thoracoabdominal aorta. Arch debranching and viscero-renal artery translocation may avoid the use of thoracoabdominal incisions, cardiopulmonary bypass techniques, deep hypothermia, and circulatory arrest.
