Is Warfarin Indicated in Behcet's Syndrome Associated with Thrombosis? Reflections on Treatment and Death of a Patient

Prophylactic prosthetic wrapping for vascular anastomosis in patients with Behçet's aortic aneurysms: an experience from a resource-challenged setting

BACKGROUND

The objectives of the current study were to evaluate our technical and clinical results of surgical treatment of infrarenal Behçet's abdominal aortic aneurysm (AAA). In addition to the prosthetic wrapping of the constructed anastomosis as a prophylactic measure for patients with vasculo-Behçet's disease, together with the administration of per- and postoperative immunosuppressive therapy.

METHODS

A single-center retrospective case series included 16 patients with vasculo-Behçet's AAA who treated with open surgical repair, between January 2005 and December 2013. The administration of immunosuppressive treatment was done preoperatively to achieve complete remission of the disease activity before starting the surgical repair. Patients' data were retrieved and analyzed emphasizing the diagnostic procedures, the used surgical techniques, and suitable graft selection, as well as, graft-related complications. The patients were followed up for one month to a maximum of 72 months. The median follow-up period was 24.83±9.4 months.

RESULTS

This study included 16 patients, 10 (63%) males, and 6 (37%) females, with the median age of (30.50 years, range: 21-37 years). Moreover, all patients were anticoagulated and discharged on warfarin and aspirin therapy. All surgical procedures were done on an elective basis except for only one emergency laparotomy, which was performed for a life-threatening ruptured aneurysm. The vascular anastomoses were performed using either interposition tube graft (for isolated AAA), or Y-shaped graft (for concomitant aorto-iliac aneurysms). Furthermore, prophylactic prosthetic wrapping was applied encircling the graft to the host artery. In addition, all patients received systemic immunosuppressive therapy post-surgical intervention to prevent anastomotic site complications. Technical success was obtained in 100% of cases. Moreover, the patients were followed up for a period of 12-72 months. Two anastomotic pseudoaneurysms were developed postoperatively. More interesting is that both were infected (one low-virulent that was conservatively treated and one overt that was surgically repaired). Furthermore, there was no aneurysm-related mortality.

CONCLUSIONS

Prophylactic prosthetic wrapping of vascular anastomosis in patients with Behçet's AAA in resource-challenged settings, where the proximal anastomoses were all end-to-end with wrapping, is an affordable, simple, reliable, and feasible technique, and commonly associated with a lower incidence of anastomotic site false aneurysms and different complications related to the implanted graft, where endovascular procedures might not be applicable. Moreover, the proper preoperative medical preparation for controlling the activity of Behçet's disease, with the administration of immunosuppressive agents, followed by immediate postoperative therapy, may have a good impact on the operative technical success and the prevention of the development of serious postoperative complications; especially anastomotic pseudoaneurysms (which may be complicated by fatal hemorrhage), as well as other graft-related complications.

Demography of vascular Behcet's disease with different gender and age: an investigation with 166 Chinese patients

Background

The Clinical features of vascular Behcet’s disease (BD) are not well understood because there are few studies. Our study aimed to investigate characteristics of vascular BD in both genders in different age groups.

Results

We enrolled 923 patients with BD who presented to our hospital with adequate medical histories and proper vascular screening exams. The raw incidence rate of vascular BD was 17.98% (166/923). The ratio of vascular BD in male to female patients was 1.868 (p = 0.0004, 95% confidence interval (CI): 1.317 to 2.625). There was a tendency towards higher ESR and CRP in vascular BD patients than in mucocutaneous, but the difference was not significant. The most susceptible affected vessels were cerebral (29.6% in males, 59.4% in females) and lower limb vessels (31.2% in males, and 17.2% in females). The incidence of vascular involvement in younger (< 50 years old) and older (≥ 50 years old) patients were similar, with ratios of 16.58% (122/736) and 23.53% (44/187) respectively. However, in females, younger patients were less likely to have vascular involvement than were older patients (11.43% vs. 20% p = 0.0328, OR: 0.5161, 95% CI: 0.2874 to 0.912). Aneurysm or pseudoaneurysm was diagnosed in 1.84% (17/923) patients, mostly in male patients (p < 0.05, OR: 3.221, 95% CI: 1.097 to 9.112). Twenty vascular BD patients were followed up, and the age at BD diagnosis was 33.23 ± 11.56 year. This did not differ statistically with their age at vascular involvement (36.15 ± 9.52 years). Ages of vascular BD patients did not differ significantly from those of mucocutaneous BD patients (n = 143) in both males and females.

Conclusion

Vascular BD, including lethal types of aneurysm is more likely to occur in male patients. The female patients has a similar incidence rate with the males in their postmenopausal age. There was no evidence of progression course from mucocutaneous BD to vascular involvement.
