Bilateral ligation of the anterior division of the internal iliac arteries can be a lifesaving intervention for severe pelvic hemorrhage. The procedure results in decreased pelvic perfusion and promotes coagulation. The classical method of internal iliac artery ligation involved extensive retroperitoneal dissection with complete circumferential isolation of the vessel to allow the passage of a suture around the artery. This can be surgically challenging and fraught with risks of inadvertent injury to the surrounding iliac veins. We propose a contemporary technique that requires limited dissection of the anterior division of the internal iliac artery. A few millimeters of space is created on either side of the artery by spreading right-angle forceps parallel to the vessel. The artery is occluded by 2 large vascular clips. Because circumferential vessel dissection is not necessary with this technique, there is limited disruption of the delicate underlying internal iliac vein. In addition, this approach may decrease the risk of inadvertent injury to the adjacent external iliac vein. By showcasing the ease of our approach to internal iliac artery ligation, we hope to empower surgeons with an alternative approach to this lifesaving procedure.
双侧髂内动脉前支结扎术可作为治疗严重骨盆出血的救命干预措施。该手术可减少骨盆灌注,促进凝血。经典的髂内动脉结扎术需要广泛的腹膜后解剖,完全环绕血管隔离,以便在血管周围穿过缝线。这可能具有挑战性,并且存在周围髂静脉意外损伤的风险。我们提出了一种需要对髂内动脉前支进行有限解剖的现代技术。通过将直角钳平行于血管展开,在动脉的两侧创建几毫米的空间。用 2 个大血管夹闭塞动脉。由于这种技术不需要环绕血管解剖,因此对下方精细的髂内静脉的破坏有限。此外,这种方法可能会降低对相邻髂外静脉意外损伤的风险。通过展示我们进行髂内动脉结扎的简便方法,我们希望为外科医生提供一种替代这种救命手术的方法。
