ABSTRACT
Splenic artery embolization is often used before laparoscopic splenectomy in cases of splenomegaly to reduce blood loss and facilitate the procedure. The aim of this study was to examine the general reliability of endovascular staplers when fired at the site of embolization coil deployment using a porcine model. Ex vivo and in vivo experiments were conducted on porcine abdominal aortas, which are similar in diameter to those of the splenic artery in the human. When the endovascular staplers were fired across the porcine vessels at the area of embolization coil deployment ex vivo, the staple lines all failed. In contrast, in vivo, the staple lines remained intact with no bleeding despite resistance imposed by the intravascular coils. Despite consistent failure in the ex vivo studies, in vivo all staple lines held and permitted safe transection of the vessel. We presume that the hemostatic properties of the coils caused sufficient thrombosis in this model, which mimics the clinical situation, to permit division of the previously embolized splenic vessel.
