Interventional Radiology


Modern technology allows investigation and treatment of many conditions in a minimally invasive fashion that often previously required open operations. Dr Peter Nathaniel is one of a small group of radiologists in South Africa qualified and experienced in in this specialised area of radiology. He is based at our Sandton Medi-Clinic branch where our state-of-the-art interventional suite is situated.

Interventional Radiology is a clinical subspeciality that uses fluoroscopy, CT and ultrasound to guide percutaneous procedures such as biopsies, drainage of fluids, inserting catheters, or dilating or stenting narrowed ducts or vessels, or insertion of coils into aneurysms. Minimally invasive treatment of a wide range of conditions can be provided by interventional radiology. Examples include: diagnosis and embolisation of bleeding arteries following trauma, insertion of catheters for vascular access, insertion of vascular and biliary stents, embolisation of uterine fibroids or tumours, insertion of coils or stents into aneurysms, nephrostomy or ureteric stent placement, treatment of epistaxis, fibrinolysis of thrombi, and percutaneous abscess drainage.

Services provided include:

  • vascular angiography
  • vascular ballooning and or stenting
  • biliary stenting
  • embolisation of uterine fibroids (UFE)
  • embolisation of vascular tumours
  • emergency embolisation of internal bleeding vessels, e.g. following trauma, or severe nose beeds
