Background: We report our experience in the endovascular treatment of type B aortic dissection
Methods: Over a period of 69 months, a total of 41 type B aortic dissections (12 acute, 8
subacute, and 21 chronic dissections) were treated with stent graft in 33 cases and
multilayer stents (MLSs) in 8 cases. Our series included 40 patients (One patient
was operated for a double location): 9 women and 31 men with an average age of 64.9
years (21–84 years). Results: We had 100% technical success. Hospital mortality occurred in one (1.4%) patient.
Follow-up was available for 39 patients at a median time of 26.5 months (1–69 months).
We had 12 (8% [5/39]) complications: endoleak type II in 2 cases, chimney endoleak
in 2 other cases, and 1 case of retrograde dissection. The late mortality rate was
10.2% (4/39). Late computed tomography scans' control was satisfying for acute dissections
treated in emergency with stent graft and localized dissections treated with MLS.
Regarding the dissecting aneurysms, the false lumen was patent in the abdominal aorta
in eight cases with dilatation of the celiac aorta in four cases. Conclusion: Endovascular treatment has remarkably improved the prognosis of type B aortic dissections;
however, long-term monitoring is mandatory.
