Takayasu arteritis Therapeutic alternatives and long term outcomes

The aim of this study was to describe the long term prognosis of 34 patients with Takayasu arteritis and the results of surgical and endovascular treatment. A total of 5 central surgeries and 53 endovascular procedures were performed including 18 bypass surgeries (33.8%) and 35 angioplasties (66.2%). The median follow-up was 7.5 years, interquartile range [IQR] 2.6-12.5. Among the 18 bypass surgeries 6 (33.3%) had events, while in the 35 patients with endovascular treatment there were 16 events (45.7%). The overall 1-, 3-, 5-, and 10-year death and arterial complication-free survival rates were 80% (95% CI between 74 and 89%), 68% (95% CI between 58 and 79%), 65% (95% CI between 54 and 76%) and 47% (95% CI between 41 and 62%). Both revascularization techniques were initially successful. In long term follow-up there was a high restenosis recurrence rate with endovascular treatment requiring repeated revascularization to the same vessel in 41% of the cases. Surgery had higher mortality in patients with aortic and ascending aortic valve disease, combined coronary artery disease and carotid disease. In long term follow up Takayasu arteritis frequently requires revascularization and restenosis or new lesions are common. Surgical treatment had better results with less restenosis than angioplasty.
