Current role for endovascular treatment of ruptured abdominal aortic aneurysms


Veith, Frank J; Cayne, Neal S; Berland, Todd L; Mayer, Dieter; Lachat, Mario (2012). Current role for endovascular treatment of ruptured abdominal aortic aneurysms. Seminars in Vascular Surgery, 25(3):174-176.

Abstract

Endovascular repair of ruptured abdominal aortic aneurysms seems to have better outcomes than open repair if certain strategies, techniques, and adjuncts are employed. These include a standard approach or protocol; use of fluid restriction (hypotensive hemostasis), performance of the procedure in a site equipped for excellent fluoroscopic imaging and open surgery, use of percutaneous approaches and local anesthesia for initial guide wire and catheter placement, placement of a large supraceliac aortic sheath, and obtaining balloon control only when absolutely necessary. Details of obtaining this control are critical, and aortic control must not be lost until the rupture site is excluded. Multiple balloons might be required, including ones placed within the endograft. Sheath placement and fixation until the balloon is removed are also critically important. Bifurcated and unilateral endografts can be used successfully. Abdominal compartment syndrome must be looked for and treated aggressively; endovascular repair must be used in the highest-risk patients, including those in profound hemorrhagic shock, to gain the greatest advantages of this approach.
