Abstract:
During laparoscopic enucleation of an interstitial pregnancy, adequate hemostatic control is of paramount importance due to the high vascularization of the uterine cornus. However, no consensus or guidance exists regarding the optimal hemostatic technique. We report laparoscopic reversible uterine arteries occlusion as hemostatic technique during laparoscopic enucleation by cornuostomy of an interstitial pregnancy at advanced gestational age (46 × 40 mm gestational sac). Preliminary identification of the uterine arteries and bilateral reversible occlusion by Hem-o-Lok clips allowed bleeding control during surgery. The laparoscopic procedure was performed without complications and with limited blood loss. The reported case reinforces the feasibility of this minimally invasive technique in interstitial pregnancy.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
