External iliac artery thrombosis after common iliac artery balloon occlusion during cesarean hysterectomy for placenta accreta in cervico-isthmic pregnancy

摘要

Although the role of interventional radiology in the field of obstetrical hemorrhage has been widely reported upon recently, the rate of procedure-related complications has not been fully determined. We present the case of a patient who developed an external iliac artery thrombosis, a rarely reported complication associated with prophylactic common iliac artery balloon occlusion (CIABO). After CIABO, we found that the dorsalis pedis artery of the right foot was weak and the foot was cold, despite the fact that the patient had no complaints. Computed tomography demonstrated a linear thrombus in the right external iliac artery. We managed the patient conservatively using a heparin drip without the need for thromboembolectomy. Our experience suggests that it is important to consider the risk of thrombosis formation after CIABO. Physical examination post-procedure is key to identifying this complication early.
