New Cross-linked Hyaluronan Gel to Prevent Adhesion After USG-MVA: RCT

Modification of Hyaluronic acid structure to 3-dimensional self-cross-linked network structure enables all-dimensional coverage of tissue surface to enhance better healing process. Self-cross-linked HA hydrogels can maintain the biocompatibility and biodegradability that characterize the unmodified material. Moreover, high dynamic viscosity enables continuous indwelling in the uterine cavity. The gel could provide precise regulation, and degradation and absorption time prolonged to 7-14 days post operatively, which completely cover key postoperative healing period (5-7 days), at the highest time of intrauterine adhesion formation.
