MR imaging features of uterine necrosis following modified B-Lynch sutures: a case report

B-Lynch braided compression sutures are applied as a lifesaving procedure to control atonic post-partum hemorrhage if the patient is not responding to uterotonics and other conservative methods. These sutures are applied to avoid hysterectomy so as to preserve fertility. However, if not applied properly, these can lead to a rare but serious complication of uterine necrosis secondary to uterine ischemia and sepsis. The patient then ends up in hysterectomy defeating the sole purpose of maintaining fertility for which the sutures were applied at the first place. Here we describe a case of primipara who had caesarian section complicated by post-partum hemorrhage which was managed with modified B-Lynch compression sutures for achieving hemostasis. The patient presented three weeks post-procedure with signs and symptoms of inflammation and sepsis. The MR imaging revealed features of uterine necrosis. The patient underwent hysterectomy unwillingly as no other option was left to save her life. A detailed MR imaging of this case has been described given the scarcity of MR features of uterine necrosis following compressive sutures in medical literature. The case is reported to make the clinicians aware of the possibility of such a dreaded complication following compressive sutures for post-partum hemorrhage and to emphasize on early and timely follow-up of such patients so that uterus could be salvaged.
