Endovascular techniques in acute arterial mesenteric ischemia.

Rapid developments in preoperative noninvasive imaging as well as advanced endovascular techniques have made endovascular treatment of acute arterial mesenteric ischemia a feasible treatment option in many patients. Multidetector computed tomographic angiography will provide the diagnosis and guide treatment in most cases. The use of mechanical and aspiration embolectomy, sometimes in combination with thrombolytic therapy, is often successful in offering these very sick patients a good treatment option to open surgical revascularization. Underlying occlusive lesions can be treated in the same setting. Hybrid techniques using open abdominal exploration in combination with endovascular tools have the possibility of offering minimally invasive treatment to even more patients. Access to a hybrid operating room is very advantageous when performing these operations because it allows for performing both open and endovascular interventions in the same setting. A fixed angiographic system also minimizes radiation exposure and improves the imaging capabilities compared to a conventional, mobile C-arm. These tools must be used in conjunction with wise, careful clinical evaluation of the patient.
