Surgical Experience of Behcet's Disease Involving the Peripheral Artery

Background:: Behcet's disease with arterial involvement shows rapid poor progression compared with Behcet's disease without arterial involvement, such that it may be thought of as a different disease. With arterial involvement, high rates of postoperative recurrence and anastomotic complications are observed.Methods:: The medical records of 1,361 patients diagnosed with Behcet's disease who visited our hospital from January 2007 to December 2019 were reviewed. Overall, 118 patients with blood vessel involvement were considered. Those with only vein involvement, intracerebral arterial involvement, and coronary arterial involvement were excluded. The 8 patients who underwent surgical treatments and the 9 patients who underwent conservative treatments were included and reported in this study.Results:: The mean age and mean follow-up duration of the 17 patients with peripheral arterial involvement were 49.82 +/- 13.24 years and 89.85 +/- 52.70 months, respectively. In all cases where the operations were performed, the first operation was an emergency operation for rupture of the aneurysm, impending sign of rupturing, or acute ischemia. Eight patients received a total of 18 operations. The average number of operations per patient and the reoperation rate were 2.25 +/- 0.89 times and 75%, respectively. The 5-year and 10-year survival rates of the patients who underwent surgery were 75.0% and 30.0%, respectively. When arterial involvement occurs in the form of an aneurysm, the hazard ratio for death is 9.644 (P = 0.040, confidence interval 1.11-83.74).Conclusions:: When the artery invades in the form of an aneurysm, the mortality rate is higher regardless of surgery. The main cause of mortality is complications that occur in the anastomosis sites after the operation. Postoperative short-term and regular imaging of the anastomosis area can be beneficial to detect such complications early to decrease the frequency of emergency surgeries, which will help reduce mortality.
