Superselective interventional angiography uses a coaxial catheter system for precise vascular access. This minimally invasive technique offers targeted treatments with reduced side effects for revascularization and occlusion procedures.

Area of Science:

  • Interventional Radiology
  • Vascular Surgery
  • Medical Devices

Context:

  • Superselective angiography enables precise navigation within peripheral vascular networks.
  • A coaxial catheter system, including a guiding and a flexible internal catheter with a steerable guidewire, facilitates advanced microcatheter placement.

Purpose:

  • To describe the clinical application and benefits of superselective interventional angiography.
  • To highlight its utility in both revascularization and occlusion procedures.

Summary:

  • The technique employs a coaxial catheter system for superselective probing of peripheral vessels.
  • Interventional measures, such as embolization or local lysis, are performed via the microcatheter.
  • Indications include preoperative vascular occlusion, haemangioma embolization, liver tumor chemoembolization, and peripheral vessel revascularization.

Impact:

  • Superselective angiography allows for on-target interventions, significantly reducing the incidence of side effects compared to conventional methods.
  • This approach enhances treatment efficacy and patient safety in complex vascular interventions.
