Imaging Studies VII: Vascular Imaging

46
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

145
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Area of Science:

  • Neuroradiology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Spinal angiography (SpAn) is essential for diagnosing spinal dural fistulas and arteriovenous malformations.
  • Traditional transfemoral access for SpAn can be challenging.
  • Transradial access is gaining popularity for endovascular procedures, but its use in SpAn is under-documented.

Purpose of the Study:

  • To evaluate the safety and efficacy of transradial access for spinal angiography.
  • To assess the feasibility of transradial access for diagnostic and interventional SpAn procedures.

Main Methods:

  • A retrospective review of patients undergoing SpAn between July 2019 and December 2020 was conducted.
  • Institutional Review Board (IRB) approval was obtained.
  • Patient records and imaging data were analyzed.

Main Results:

  • Nine SpAn procedures were performed using transradial access in eight patients.
  • Eight procedures were diagnostic, and one involved treatment of a type I spinal dural arteriovenous fistula.
  • No complications were reported during or after the procedures.

Conclusions:

  • Transradial access is a safe and successful method for performing spinal angiography.
  • This approach provides a stable platform for interventional procedures, expanding treatment options.
