The patient was a 61-year-old man who underwent total right hip replacement due to osteoarthritis in July 2015. Infection occurred during his postoperative course, and reimplantation was performed in December 2015. Around 2 weeks postoperatively, progression of anemia and pain in the inner aspect of his right thigh appeared. Contrast-enhanced CT confirmed a pseudoaneurysm of the right deep femoral artery branch, surrounded by a hematoma, and embolization for the pseudoaneurysm was scheduled. Angiography was performed, which revealed interruption of the right deep femoral artery branch and a pseudoaneurysm of 68 mm in its greatest dimension. A 6-mm×20-cm interlocking detachable coil (IDC coil) was placed in the ruptured blood vessel, but it was shed into the bloodstream, and the coil prolapsed in the aneurysm. Additional placement of an 8-mm×20-cm IDC coil was attempted, but it was not detached because of instability and was removed. Next, a 4 Fr angiographic catheter was inserted into the culprit vessel, and an 8-mm-diameter Amplatzer Vascular Plug 4 was placed, which resulted in blockage of the ruptured blood vessel. Subsequent contrast-enhanced CT did not show vascular recanalization, indicating that good results were obtained. We report the present case and review the literature.
