About the Lab
Professor Gwang Bo Park's research lab specializes in interventional radiology, with a primary focus on endovascular and percutaneous interventions for vascular and biliary pathologies. The lab investigates minimally invasive techniques such as stent placement, balloon angioplasty, and embolization to treat complex vascular stenoses, including portal vein stenosis after liver transplantation and malignant obstructions of the biliary and gastrointestinal tracts. A key emphasis is on improving long-term outcomes and managing rare but severe complications, such as delayed hemorrhage after stent placement. The lab combines clinical interventional radiology with hemodynamic and radiologic evaluation to optimize patient care and therapeutic strategies.

15The described angiographic classification provides considerable information concerning the characteristics of AVMs in the body and extremities, the optimal therapeutic approach, and the likely therapeutic outcome.
Flexible covered metallic stent placement can be useful for palliation in patients with malignant obstruction of the gastric outlet or duodenum.
Percutaneous transhepatic balloon angioplasty is an effective treatment for the portal vein stenosis that occurs after liver transplantation, and our results showed good mid-term patency with using this technique.
Iliac arterial stent placement is a safe treatment with favorable long term patency. Lesions in the EIA or lesions in both the EIA and CIA, poor run off vessels and a stent having the same or a larger diameter than 10 mm were the poor prognostic factors for long term stent patency.
Objective: We wanted to valuate the mid-term therapeutic results of percutaneous transhepatic balloon angioplasty for portal vein stenosis after liver transplantation. Materials and Methods: From May 1996 to Feb 2005, 420 patients underwent liver transplantation. Percutaneous transhepatic angioplasty of the portal vein was attempted in six patients. The patients presented with the clinical signs and symptoms of portal venous hypertension or they were identified by surveillance doppler ultrasonog
BACKGROUND: Life-threatening, delayed hemorrhage after self-expandable metallic stent (SEMS) insertion for malignant biliary obstruction is very rare. Clinical manifestations, radiologic characteristics, treatment, and prognosis of this complication are not well-known. PURPOSE: To present the clinical manifestations, radiologic findings, and endovascular treatment of life-threatening, delayed hemorrhage secondary to SEMS placement. MATERIAL AND METHODS: A total of six patients (five men and one
