Abstract

Objectives: Cervical aortic arch with aneurysm formation is considered an extremely rare condition. Here, we summarize our experience in treating 8 patients. We validated extra-anatomic ascending-to-infrarenal abdominal aorta bypass through the retroperitoneal cavity without circulatory arrest as an alternative treatment for patients with a tortuous arch that was unsuitable for endovascular repair.

Methods: From March 2015 to April 2018, 8 patients (7 women; median age 46 years) diagnosed with cervical aortic arch complicated with aneurysm formation were treated at Peking Union Medical College Hospital and the Affiliated Hospital of Qingdao University. After assessment of the anatomical characteristics, 4 patients underwent endovascular repair. Three patients with a tortuous aortic arch and saccular aneurysm formation between the left common carotid artery and the left subclavian artery were treated with an extra-anatomic ascending-to-infrarenal abdominal aorta bypass and aneurysm indwelling. One patient refused surgical intervention and is being followed up on a yearly basis at our outpatient clinic. No circulatory arrest was required during surgery.

Results: No severe postoperative complications were observed during follow-up (6-36 months). Postoperative computed tomography angiography revealed patent blood flow in the prosthetic aortic graft bypass. No endoleak, migration or stenosis of the stent grafts was observed in patients following endovascular repair. The left subclavian artery was preserved in 3 patients. Follow-up computed tomography angiography revealed satisfactory postoperative results in all patients, with no signs of aortic dilation or coarctation.

Conclusions: Ascending-to-infrarenal abdominal aorta bypass through the retroperitoneal cavity is a safe and effective treatment for cervical aortic arch with a tortuous aorta complicated by aneurysm formation and coarctation.
