Introduction/Background Vascular malformations and variations are commonly recognized in pelvic and paraaortic area which makes retroperitoneal surgery challenging. Laparoscopic approach is gaining popularity in every aspect of gynecologic oncology and vascular complications could rarely occur in these regions. Laparoscopic surgeon should be aware of and prepared for vascular complications which carry a high morbidity rate.

Methodology Video presentation of four cases

Results In this video in the first two cases the management of bleeding due to injury to branhces of hypogastric artery (vesical and obturatory) during laparoscopic pelvic lymphadenectomy is presented. The third case is about management of plexus bleeding just above the anteriror vertebral ligament in interaorticocaval region during laparoscopic paraaortic lymphadenectomy. Fourth case presents an aberrant ovarian artery located just under IMA which was recognized and preserved without any complications in paraaaortic lymphadenectomy.

Conclusion There is a small but significant risk of vascular injury and related morbidities in laparoscopic pelvic and paraaortic lymphadenectomy due to vascular anomalies, variations, suboptimal visiulisation of surgical field and patient parameters such as obesity and previous surgeries. Laparoscopic surgeon should be familiar with vascular complications and should be able to manage the complicaitons to mimimize the morbidity related to vasuclar injury.
