The Use of Branch with Slot Coated Stent in the Treatment of Complex Thoracic Aortic Dissection
Abstract: Objective: To research the use of branch with slot coated stent for endovascular exclusion in the treatment of complex thoracic aortic dissection. Methods: Totally 2 patients with complex thoracic aortic dissection were treated by EVAR (Endovascular Aneurysm Repair) with branch slot coated stents between Oct. 2012 to Dec. 2012 at our department. Because the bow of thoracic aortic dis-section and the crevasse are close to the left subclavian artery and common carotid artery which are unsuitable for standard EVAR, we choose EVAR with branch slot coated stent. During the procedure, by femoral artery incision, we introduced a guide wire through the thoracic aorta and another guide wire through the left brachial artery to reach the left subclavian artery, descending aorta, thoracic aorta and eliciting it from the femoral artery incision. And then, the main stent was placed through the guide wire in the thoracic aorta and the branch stent was placed through the guide wire in the left subclavian artery. Then make an angiography from the unknown artery puncture to make sure the placement of the stent is right, and release the main stent and the branch stent subsequently. Results: The success rate of the procedure was 100%. Angiography at the end of the operation showed normal blood flow into the left subclavian artery, common carotid artery and the crevasse of thoracic aortic dissection was well-separated. There is no inner leakage in the two cases. Conclusion: Branch slot coated stent is an effective supplement of conventional EVAR which is unsuitable for patients with complex thoracic aortic dissection. Further study is necessary to observe its long-term outcomes.
