The development of thoracic endovascular aortic repair(TEVAR)technology avoids the risk of patients opening the chest and is widely used in Stanford B-type dissection.[1–3]However,because TEVAR technology has clear requirements for vascular anatomy of the lesion,it limits its application to some *** the shortcomings of the proximal anchor zone,coverage of the left subclavian artery(LSA)origin without revascularization during TEVAR appears to have increased risk of stroke,upper extremity ischemia and paraplegia.[4]

Background:Here we analyzed mid-term data of thoracic endovascular aneurysm repair(TEVAR)surgery with Castor single-branched stent graft placement for the management of Stanford type B aortic dissection(STBAD)involving the left subclavian artery(LSA).Methods:Between April 2014 and February 2019,32 patients with STBAD involving a Castor single-branched stent graft were *** analyzed their outcomes,including technical success rate(TSR),surgical duration(SD),presence of ischemia,perioperative complications,LSA patency,and survival rate(SR),using computed tomography angiography and clinical evaluation during mid-term ***:The mean patient age was 54.63±12.37 years(range,36–83 years).The TSR was 96.88%(n=31/32).The mean SD was 87.44±10.89 with a mean contrast volume of 125.31±19.30 *** neurological complications or deaths occurred during the study *** patients had a mean hospital stay of 7.84±3.20 *** a mean follow-up of 68.78±11.26 months,four non-aortic deaths(12.5%)were *** LSA patency rate was 100%(n=28/28).There was only one case of type I endoleak immediately after surgery(3.12%)(type I from LSA).However,none of the patients experienced type II endoleaks,and there were no cases of retrograde type A aortic dissection or stent graft-driven new distal ***,all patients exhibited good LSA ***:TEVAR using a Castor single-branched stent graft may be a highly feasible and efficient procedure for the management of STBAD involving the LSA.

Aortic dissection （AD） is a catastrophic disease involving the aorta. Most intimal tears are located in the ascending aorta or the first portion of the descending aorta.1 It is a rare case that the proximal tear originates from the left subclavian artery （LSA）. Virtual endoscopy （VE） technology could provide us a specific perspective to see from intraluminal to the outside and was especially helpful to look for and indentify complicated intimal tears.^2 Vascular occluder is a useful device to treat vessel diseases alone or combined with other appratus.

Aortic dissection is a rare but potentially life-threatening condition, with an estimated incidence of about three cases per 100 000 persons. Thoracic endovascular aortic repair （TEVAR） has emerged during the last decade as a less invasive treatment modality for aortic dissections, most commonly for Stanford type B aortic dissection （type B-AD）, that can lessen surgical morbidity and mortality, decrease hospital stay, and provide excellent short- and mid-term outcomes.

Background Most of endovascular stent-graft modifications to preserve side branch must be customized according to extensive pre-operative assessment, which may not be possible in many hospitals and emergency settings. The study was to develop a novel stent-grafts system that would allow in situ ＂fenestration＂, with less reliance on preoperative imaging. Methods The magnitude of pressure difference （PD） between left subclavian artery （LSA） and aortic arch were measured in 12 experimental pigs. Changes of PD before and after LSA was covered were analyzed respectively. The novel stent graft was made by multi-dimensional and multiple textiles forming technology. According to the PD measurement in pigs, we evaluated the feasibility of the stent-graft in a mock circulation system. Results In pigs, the blood pressure of aortic arch was significantly higher than that of LSA after it was covered （P 〈0.001） and PD was （42.78±5.17） mmHg. After target vessel was covered and when PD between the LSA and aorta reached the magnitude measured in pigs, contrast media oozed from the cranny of graft to the LSA, which was generated by sliding and deformation of yarns of novel stent-graft. Conclusions The study proposes the design of pressure difference-induced perforation aortic stent-grafts system and verifies that the PD between LSA and aortic arch is high enough to allow in situ ＂fenestration＂ by stent graft made by multi-dimensional and multiple textiles forming technoloav.

In patients with history of coronary artery disease angina pectoris is usually attributed to the progression of atherosclerotic lesions. However,in patients with previous coronary artery bypass graft operation(CABG) using internal mammary artery grafts,great vessel disease should also be considered. Herein we present two patients with history of CABG whose symptoms were suspicious for coronary ischemia. During cardiac catheterization reverse blood flow was observed from the left artery disease to the left internal mammary artery(LIMA) graft in both cases. After angioplasty and stent implantation of the left subclavian artery antegrade flow was restored in the LIMA grafts and both patients had complete resolution of symptoms.
