Popliteal Pseudoaneurysm Complicated by Massive Hematoma following Catheter-Directed Thrombolysis for a May-Thurner Syndrome Patient with Deep Vein Thrombosis

We present a patient with massive deep vein thrombosis (DVT) resulting from May-Thurner syndrome as known as the iliac vein compression syndrome. He underwent an angioplasty procedure in which stents were placed at ileofemoral vein and catheter-directed thrombolysis was performed. This angioplasty procedure was complicated by blood vessel wall injuries such as pseudoaneurysm at his right popliteal blood vessel. Manual compression, thrombin injection to pseudoaneurysm and hematoma aspiration could not resolve the complications. Finally, surgical drainage could completely resolve the hemorrhagic complications. Therefore, catheter-directed thrombolysis requires particular attention to post-procedure close observation, especially, within one week of onset of DVT as well as within 48 hours of procedure.
