Laparoscopic systemic devascularization of uterine cornu for cornual resection in interstitial pregnancy

Cornual pregnancies carry a greater maternal mortality risk than ampullary ectopic pregnancies and they may cause significant hemorrhage. A woman aged 36 years with a six-week history of amenorrhea, slight vaginal bleeding, and low abdominal pain of three days duration presented to our clinic. A diagnosis of right cornual ectopic pregnancy was made using ultrasonographic findings. Laparoscopic exploration confirmed the diagnosis. We occluded the uterine artery at its origin and also transected vessels within the mesosalpinx and uteroovarian ligament to successfully accomplish avascularization of a cornual pregnancy. Occlusion of the uterine arteries is reported to be a safe and blood-sparing technique. Severe hemorragia may occur during the operation; therefore, techniques to minimize blood loss are reported. In our case, occlusion of the uterine artery and transection of the mesosalpinx and uteroovarian vessels provided a bloodless operation and there was no need to bilaterally occlude vessels.
