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

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.
