OBJECTIVE: To retrospectively evaluate the technical feasibility and midterm results of uncovered thoracoabdominal stent placement in complicated acute @entity1580 Stanford type B (cAADB). @entity1 AND METHODS: Fourteen consecutive @entity1 (3 females; range, 44-71 years) with cAADB who had symptomatic @entity344 and claudication underwent immediate uncovered stent implantation (diameter, 7-28 mm; length, 40-100 mm) into the true lumen of the thoracoabdominal aorta (n = 23) and visceral arteries (n = 5). RESULTS: Stenting resulted in elimination of @entity344 and symptoms in 13 of 14 @entity1 ; persisting symptoms led to secondary surgical revascularization in only 1 @entity1 . More than 1 stent ( <= 4) was placed in 7 @entity1 (2 celiac, 1 mesenteric, 2 renal, 8 aorto-iliac). Follow-up computed tomographic angiography (CTA) revealed collapse of 4 aortic stents (diameter, 9-25 mm; length, 100 mm) at 1 week in the absence of symptoms. Balloon reexpansion was possible in all 4 stents, but recollapse occurred within 1 month. Despite stent collapse, the @entity1 remained asymptomatic; ultrasonography and CTA documented sufficient perfusion of the visceral arteries in all @entity1 . Follow-up ranged from 6 months to 5 years (average, 2.5 years). Except for the @entity1 who underwent iliacomesenteric bypass for unspecific @entity490 , no other @entity1 required additional interventional or surgical therapy. CONCLUSIONS: Acute @entity1580 with suspicion of @entity63 should prompt for immediate intervention. Thoracoabdominal uncovered stent implantation is a technically feasible and effective minimally invasive approach that provided successful relief of acute @entity63 and claudication in cAADB. Stent size should be less than the normal aortic diameter to avoid possible stent collapse.
