摘要
Therapeutic strategies for treating Stanford type B dissection with endo-organ malperfusion remain controversial, and whether surgery or conservative treatment should be performed is a matter of ongoing debate. In this study, we examined the treatment strategies used in cases of malperfusion in which treatment was initiated conservatively at the onset of symptoms without superior mesenteric artery (SMA) or limb artery obstruction. A total of 16 patients had organ ischemia in this series. The obstructed branches were the SMA in 5 patients, the artery of Adamkiewicz in 2, the bilateral renal arteries in 3, the celiac artery in 3 and limb arteries in 3. The surgical procedure included bypass grafting in 2 patients with SMA obstruction and extra-anatomical bypass in 2 patients with limb artery obstruction. A total of 11 patients were treated without surgery. Three patients died, including 2 patients with SMA obstruction. The remaining patient who died had limb artery obstruction and did not undergo surgery. The results suggest that patients with acute type B aortic dissection with endo-organ malperfusion who develop SMA or limb artery obstruction require early surgery.
