Preoperative Embolization of the Inferior Mesenteric Artery in Colorectal Surgery

"The procedure is performed in a dedicated angiography room. After local anesthesia, a common femoral arterial approach is performed according to the Seldinger technique with the placement of a 4 French valve introducer.~Catheterization of the superior mesenteric artery with a Cobra 4F catheter and angiography to confirm patency of the border arcade.~Catheterization of the inferior mesenteric artery with a 4F cobra/shepherd hook catheter and angiography. Microcatheterization of the artery with a 2.7F or 2.8F microcatheter and embolization with microcoil leaving the first centimeters of the IMA in order not to interfere with the surgery.~Catheterization of the superior mesenteric artery and final angiography to confirm the reinjection of the inferior mesenteric by the border arcade.~Removal of the material and manual compression of femoral access. Clinical monitoring for 6 hours and discharge the same day of the procedure."
