Interventional Radiology Center
Specialized medical services
Our center offers minimally invasive non-surgical procedures known as interventional radiology (IVR). A wide variety of diseases are examined or treated using angiographic catheters or needles under radiological image guidance by angiography, ultrasound, or computed tomography (CT). Most procedures are performed under local anesthesia in the Clinic of Radiology. Procedures requiring general anesthesia and those for trauma or acute critical care are occasionally performed in the operation rooms and emergency rooms. As on-call responsibility, we respond to requests for emergency procedures at night and on holidays. We also have outpatient clinic, providing patient examinations and consultation on indicated treatments. We have organized a dedicated team of physicians, radiology technologists and nurses to provide the latest interventional techniques as below:
- Tumor embolization
- Chemoembolization of liver cancers
Uterine fibroid embolization (UFE)
Renal tumors, head and neck tumors, bone and soft tissue tumors
- Embolization for vascular lesions
- Visceral aneurysms, arteriovenous malformations (AVMs), aortic aneurysm endoleaks, gastrointestinal varices, varicoceles
- Peripheral arterial diseases, renovascular hypertension, hemodialysis shunt failure, vascular stenosis after liver transplantation
- Venous interventions
- Sclerotherapy of venous malformations, IVC-filter placement, central venous catheter/port placement, adrenal venous sampling
- Traumatic and iatrogenic bleeding, gastrointestinal bleeding, hemoptysis, postpartum hemorrhage, epistaxis
- CT-guided tumor biopsy
- CT-guided tumor ablation
- Radiofrequency ablation for liver cancer, cryoablation for renal cancer
- Biliary drainage and stenting
- Abscess and cyst drainage
IVR procedures, as they are minimally invasive, have become an essential option in the diagnostic and treatment process of current clinical practice. Therefore, we cooperate with the relevant departments and facilities in various fields as follows in a multi-disciplinary manner: oncology, vascular medicine, gastroenterology, respiratory medicine, trauma and acute critical care, pediatric care, maternal care, organ transplantation, infection control, risk management, and so on. We are also working to improve radiation safety and share information to minimize particular complication risks such as internal bleeding, infection, embolism related to IVR procedures.
Patient referrals and consultations
- For in-house physicians:
- Our staff responds to phone consultation on the dedicated PHS. We may ask you to refer the patient to our outpatient clinic, depending on the procedure.
- For medical facilities in the community:
- To refer a patient to our outpatient clinic, the appointment service is available via the Social Service Department. Depending on the nature of the referral, consultation at another clinical section may be recommended first. Since diagnostic imaging is essential for the decision to use IVR please ask the patient to bring film or CD-R from your facility.
