Successful Hysteroscopic Removal of a Retained Karman Cannula Tip: A Case Report.

The most frequently performed procedure for first-trimester abortions is suction evacuation due to its excellent safety profile. Complications of suction evacuation include bleeding, infections, sepsis, retained products, and, very rarely, retention of the broken tip of the Karman cannula. The literature on the retention of a broken Karman cannula tip is very scarce. We present a case of a retained Karman cannula tip during suction evacuation for a medical termination of pregnancy in a 37-year-old woman with G2P1L1 and a previous cesarean section at 12 weeks of gestation. Ultrasonography (USG)-guided retrieval with forceps was attempted but was unsuccessful. The patient was managed with hysteroscopic removal of the broken Karman cannula tip using hysteroscopic polyp forceps. The purpose of this case report is to highlight this rare but challenging complication, document the management method, and discuss points to consider during suction evacuation to prevent such occurrences.
