One-stop hybrid surgery for treatment of complex Stanford type B aortic dissection

Abstract

Objectives To compare the efficacy and prognosis of one-stop hybrid surgery using the elephant trunk procedure for treatment of complex Stanford type B aortic dissection. Methods We retrospectively analyzed patients who underwent surgical treatment from January 2014 to July 2019. The patients were divided into those who underwent the elephant trunk procedure (n = 10) and those who underwent one-stop hybrid surgery (n = 10). The cardiopulmonary bypass time, mechanical ventilation time, length of hospital stay, and red blood cell usage were compared between the two groups. All patients’ 3-month postoperative aortic computed tomography angiography (CTA) findings were also reviewed. Results The cardiopulmonary bypass time, mechanical ventilation time, and length of hospital stay were significantly shorter and red blood cell usage was significantly lower in the one-stop hybridization group. The aortic cross-clamp time was not significantly different between the two groups. Aortic CTA review after hybrid surgery showed that the true lumen of the descending aorta was almost completely restored at 3 months. Conclusion One-stop hybrid surgery effectively alleviated the occlusion of the aortic dissection, prevented the need for additional surgery, and expanded the indications for covered-stent endovascular repair.
