Does endovascular treatment prevent mortality and major complications in patients with complicated type B aortic dissections?
Endovascular treatment for complicated type B aortic dissections appears feasible and safe in a small initial series, offering a promising alternative to high-risk open surgery.
May support feasibility in select cases of complicated type B aortic dissection; leaves open need for larger prospective trials.
The purpose is to describe our experience with endovascular treatment of type B aortic dissections. Five patients were treated for complications following type B dissections like, false channel aneurysm formation, rupture and arterial obstruction. They were treated in general anaesthesia using a 'homemade' endoprosthesis or a commercially available endoprosthesis (Excluder) deployed during fluoroscopy. The patients have been followed at regular intervals with a median observation time of 18 months (range 12--36). One patient needed a secondary intervention due to dislodgement of the proximal stentgraft with haemorrhage into both the false and the true lumen. Otherwise there have been no early or late mortality or major complications in this series. Even if our experience with endovascular treatment of type B dissections is rather limited, the results so far are promising. Open surgery in many of these cases is complicated with high morbidity and mortality rate and the endovascular technique offers great advantages. A longer follow-up period is necessary to define the place of endovascular treatment.

Jan Lundbom (2001) conducted a case report in Type B aortic dissections (n=5). Endovascular treatment (endoprosthesis) was evaluated on Early or late mortality or major complications. Endovascular treatment of complicated type B aortic dissections in 5 patients resulted in no early or late mortality, with one patient requiring a secondary intervention over 18 months.
