Indication, Timing and Results of Endovascular Treatment of Type B Dissection

Comparison of medical, surgical and endovascular treatment in patients with acute type B aortic dissection.²¹

Malperfusion of distal aorta by occlusive type B dissection. Stent-graft placement in the true lumen of the proximal descending aorta re-established flow to the abdomen and legs.

Type B aortic dissection in a 48-year-old man; note that there is a dynamic obstruction of the true lumen (TL) in the acute phase. In the chronic phase, there is still a partial perfusion of the false lumen with additional partial thrombosis. After stent-graft placement across the proximal thoracic entry, the entire true lumen of the thoracic aorta is reconstructed with time, with complete ‘healing’ of the dissected aortic wall and shrinking of the completely thrombosed false lumen (FL). TH: thrombus.
