Objective To summarize the cl inical experience of vascular bypass grafting combined with endovascularaortic repair (EVAR) for aortic dilatation disease. Methods Between January 2008 and August 2011, 12 patients with aorticdilatation disease were treated with vascular bypass grafting combined with EVAR. Of 12 patients, 11 were male and 1 wasfemale, aged 47-81 years (mean, 65.9 years). All cases were diagnosed through computed tomography angiography (CTA),including 1 case of Stanford type A dissection, 5 cases of Stanford type B dissection, 4 cases of aortic arch aneurysm, and 2 casesof abdominal aortic aneurysm. Eight patients received neck artery bypass grafting before EVAR, and 4 patients underwentfemoral artery bypass grafting after EVAR. Results After operation, pulmonary infection occurred in 3 patients, renalinsufficiency in 2 patients, cerebral infarction in 1 case, decreased hemoglobin and platelets in 7 cases, and poor healing of groinwound in 1 case. Eleven patients were followed up 3-42 months, with an average of 18.6 months. In 1 case undergoing EVARof the thoracic and abdominal aorta, EVAR was performed again because new aneurysms formed at 6 months after operation,and the patient achieved good recovery after 3 months. CTA showed reduced false lumen, thrombosis formation, no endoleak,no deformation or displacement of stent, and anastomotic patency of artificial blood vessels in the other patients at 3, 6, and12 months after operation. Conclusion Vascular bypass grafting combined with EVAR can expand the indications forendovascular repair. It not only provides sufficient anchoring area, but also ensures the blood supply to vital organs, simplifiesthe surgical procedure, and reduces the difficulty of endovascular treatment.
ObjectiveTo review clinical techniques and outcomes of one-stage hybrid surgery for complex Stanford type B aortic dissection (AD), and explore the feasibility of this surgery in basic-level hospitals. MethodsSeven patients with complex Stanford type B AD underwent one-stage hybrid surgery from December 2010 to March 2013 in Department of Cardiothoracic Surgery of Xiangyang Central Hospital. There were 2 males and 5 females with a mean age of 50.0±8.3 years. Preoperative computed tomography angiography (CTA)found that the distance between breach and left subclavian artery opening was less than 15 mm in 4 patients, and left subclavian artery root were involved in 3 patients. One patient had several calcification sites of the thoracic aorta and coronary arterial stenosis near the middle segment of anterior descen-ding coronary artery by about 70%. All the patients received general anesthesia and endotracheal intubation. Firstly, bypass surgery of the branches of the aortic arch was performed via neck incision in the operating room, then endovascular aortic repair (EVAR)using femoral artery incision was performed in the catheter room. The patient with coronary artery disease received concomitant stenting of the anterior descending artery. ResultsAll the patients successfully received the operation and EVAR. Postoperatively, 1 patient had mild type Ⅰ endoleaks. No death or severe complication occurred in this group. Intraoperative angiography showed that blood flow in true lumen of AD became normal, all the bypass grafts were unobs-tructed, the positioning of stent grafts was accurate, and no stent displacement was found. All the 7 patients were followed-up for 3-24 (12.0±3.6)months, and all the patients were alive and resumed normal life during follow-up. In 6 patients, CTA at 3 months, 1 year or 2 years after the operation showed no stent graft translocation, endoleak, bypass or graft obstruction. In 1 patient with typeⅠendoleaks, CTA at 3 months after the operation showed contrast agent in the false lumen, but partial thrombosis occurred, the size and scope of false lumen were smaller than preoperative values, and the true lumen significantly became larger. CTA at 6 months after the operation showed that leakage had disappeared. None of the patients had any sign of brain or limb ischemia. ConclusionOne-stage hybrid surgery is safe and effective for the treatment of complex Stanford type B AD, expands the treatment indications of EVAR, and is worthy of widely application in basic-level hospitals.
