MID-TERM RESULTS OF LEFT SUBCLAVIAN ARTERY REVASCULARIZATION IN PATIENTS WITH THORACIC ENDOVASCULAR AORTIC REPAIR
Main Article Content
Abstract
Background: Revascularization procedures of the subclavian artery to create a convenient proximal area for stent graft placement to treat thoracic aortic disease are necessary. According to research by author Scali and colleagues (n=139) [3], stroke complications related to the left subclavian artery occlusion group accounted for a higher rate than the left subclavian artery revascularization group, times 15.8% and 8.9% of the study sample, respectively. Author Feezor RJ and colleagues (n=196), evaluating brain and spinal cord complications, noted that the left subclavian artery occlusion group had a higher risk than the left subclavian artery revascularization group [1]. Therefore, revascularization procedures should be considered in patients with thoracic aortic disease requiring stent graft placement. Methods: Retrospective description of case series. Results: The study had an average age of 65, ± 10.2 years; the majority were male, and hypertension and smoking accounted for 88.2% and 76.5% of the study sample, respectively. Aneurysm and dissected thoracic aortic lesions accounted for 52.9% and 41.2% of the sample. Transposition of the left subclavian artery into the left common carotid artery accounted for 53.3%, and the left subclavian artery to the left common carotid artery bypass with prothese accounted for 53.3% of the sample. Technical success rate reached 88.2%, complications recorded hematoma accounted for 11.8%, and stroke accounted for 5.9%. In the mid-term period, the rate of blood circulation in the head accounted for 94.1% of the sample. Conclusion: Left subclavian artery revascularization procedures in patients with stent grafts to treat thoracic aortic disease were performed safely and effectively, with few complications.
