ObjectiveTo evaluate efficacy and safety of treatment of Kommerell diverticulum with endovascular technique.MethodThe retrospective analysis was made on the preoperative clinical data, surgical treatment, and postoperative status of patient with Kommerell diverticulum who underwent the endovascular treatment in the Department of Vascular Surgery, Xuanwu Hospital of Capital Medical University.ResultsAccording to the different types and clinical symptoms, the effective endovascular treatment was adopted. The thoracic endovascular aortic repair and coil embolization of Kommerell diverticulum were successfully performed. The postoperative aortic blood flow was unobstructed and the aneurysmal lesion was completely isolated. No endoleakage and intracranial and upper limb ischemia were occurred. The operation time was 55 min and the blood loss was 20 mL. The patient was discharged on day 6 after the operation. No endoleakage, dizziness, and upper limb numbness were found following-up for 12 months.ConclusionFor patient with different types of Kommerell diverticulum and different symptoms, who could be treated by appropriate endovascular treatment and it is effective and safety.
Objective To explore the effective surgical approaches in treating subclavian artery occlusion. Methods Between December 2005 and February 2010, 53 patients with subclavian artery occlusion were treated, including left subclavian artery occlusion (35 cases) and stenosis (5 cases), right subclavian artery occlusion (5 cases) and stenosis (4 cases), and bilateral subclavian artery occlusion (4 cases). There were 40 males and 13 females with an average age of 64 years (range, 22-77 years), including 49 cases of arteriosclerosis obl iterans and 4 cases of aortic arteritis. The disease duration was 15 days to 20 months (6.5 months on average). In 49 patients with unilateral subclavian artery occlusion, 39 cases compl icated by carotid or / and cerebral artery lesion underwent axillo-axillary bypass grafting, and 10 cases without carotid or /and cerebral artery lesion underwent carotid-subclavian bypass grafting. Ascending aorta to bisubclavian bypass graftings were performed on 4 cases with bilateral subclavian artery occlusion. After operation, patients received routine treatment with anticoagulant and antiplatelet agents. Results The operations were successfully performed in 52 cases with a successful rate of 98.11%. Thrombogenesis at anastomotic site occurred in 1 case of aortic arteritis after 48 hours. Two cases had brachial plexus crush injury and 4 had hematoma around the bilateral anastomosis after axillo-axillary bypass grafting, and all recovered with nonoperative therapy. A total of 52 patients were followed up 1-52 months (24.5 months on average). All patients survived and the symptoms of basilar and upper l imb artery ischemia disappeared. Doppler ultrasonography showed that the blood flow was patent through anastomosis and polytetrafluoroethylene graft, and the vertebral artery flow was normal. Pseudoaneurysm at anastomosis was found in 1 case after 18 months and treated by interventional embol ization. The postoperative graft patency rate was 100% at 1 year and at 2 years. Conclusion Both thoracic and extrathoracic surgical approaches are effective for treating subclavianartery occlusion. The reasonable surgical approach should be selected according to the arteriopathy and the patient’s condition. Perioperative treatment and strict intraoperative manipulation are important to guarantee the success of surgery.
