Official title: Triple-branch Stent Graft Placement for the Treatment of Acute DeBakey I Aortic Dissection: A Prospective, Single-center, Open-label, Non-controlled Clinical Trial
The purpose of this study is to evaluate triple-branched stent placement in the treatment of acute DeBakey I aortic dissection . The investigators design a prospective, single-center, open-label, non-controlled clinical trial.
Read the detailed description
From November 2015, 150 consecutive patients with acute DeBakey I aortic dissection were treated with triple-branched stent placement.
In all cases, surgery was performed under general anesthesia with tracheal intubation and cardiopulmonary bypass (CPB). During surgery arterial pressures at the upper and lower limbs were monitored. An esophageal echocardiography probe was placed routinely, and a sternal incision was performed. To establish CPB, the perfusion tube was placed in the right axillary artery and the drainage tube was placed in the superior and inferior vena cava through the right atrium. The CPB flow rate was of 2.4-2.6 L/kg/min. Intermittent cold blood cardioplegia was perfused through the left and right coronary arteries for myocardial protection.
The innominate artery and the left common carotid artery were fully isolated during the CPB cooling process. The ascending aorta proximal to the innominate artery was occluded, and the ascending aorta was transected slightly above the sinus tube connection; the left and right coronary arteries were directly perfused with blood-containing cold cardioplegia. Proximal procedures such as aortic valve repair, sinus reconstruction, and root replacement were performed first. Afterwards, the stumps were reconstructed. The reconstructed aortic root stump was anastomosed with a Dacron graft of corresponding size using 4-0 polypropylene suture (ascending aorta replacement). The nasopharyngeal temperature was then decreased to 25° (usually a rectal temperature of 27-29°C), the aortic perfusion flow was set to 10-15 ml/kg/min, and the innominate artery and the left common carotid artery were occluded 5-6 cm above the aortic arch. The aortic occlusion clamp was removed and a half aortic arch transection was made about 2 cm proximal to the innominate artery. Through the incision, the true lumens of the aortic arch, the proximal descending aorta, and the three aortic branches were identified. The triple-branched stent graft was inserted into the true lumens of the aortic arch and proximal descending aorta; the three stent graft branches were then placed into the corresponding true lumens of the aortic arch branch vessels followed by the sequential release of the vascular stent backbone and the branch stents in the left subclavian artery, the left common carotid artery, and the innominate artery. A catheter with a balloon or a probe was used to expand the vascular stents and the graft and branches were examined for kinks or folding of the backbone. A sandwich reconstruction was performed between the aortic stump, the aortic external Dacron graft, and the proximal stentless suture zone of the intraluminal artificial vessel backbone. The reconstructed stump was anastomosed with the Dacron graft that replaced the ascending aorta using 4-0 polypropylene suture. The occlusions of the left common carotid artery and the innominate artery were then relieved, and air was fully flushed out from the heart and the aorta. The right axillary artery perfusion was stopped, and systemic perfusion via an aortic perfusion tube at the artificial portion of the ascending aorta was performed. The patient was rewarmed after oxygen debt repayment, followed by the cardiac resuscitation.
Telephone contact was maintained with the patients after discharge. At 3,6,12 months postoperatively , patients received a follow-up examination, chest radiography, echocardiography, bilateral carotid artery Doppler examinations and CT angiography (CTA) examinations Numerical data were expressed as percentages. Quantitative data were expressed as mean ± standard deviation. The primary end point is the occluded rate of the false lumen one year postoperatively. The secondary end point are the survive rate ,complication, reoperation rate, the growth rate of thoracic descending aorta, security index perioperatively, life quality postoperatively.Statistical analysis were performed with SPSS 11.5 software. A value of P < 0.05 was considered statistically significant.
