Radiation exposure during non-thrombotic iliac vein stenting

In plain language

In 40 iliac vein stenting procedures guided by intravascular ultrasound at one center, fluoroscopy time and air kerma were low, and higher with more stents. Staff dose was not measured directly, so implications for the fluoroscopy team are inferred.

Who was studied: Patients, Vascular surgeons
Size: n = 40 procedures
Topics: Patient dose Dose reduction techniques Dosimetry and monitoring
Summary based on: the abstract

What it found

Iliac vein stenting with intravascular ultrasound used low fluoroscopy time and air kerma.
Key figures: mean fluoroscopy time 76.5 s; mean cumulative air kerma 1.08 mGy
Placing more than one stent was associated with higher cumulative air kerma.
Key figures: 1.44 vs. 1.02 mGy; p = 0.04
Fluoroscopy time was longer when more than one stent was placed.
Key figures: 120.1 vs. 68.8 s; p = 0.0004
Patient-worn abdominal badge recorded a low deep dose equivalent per procedure.
Key figures: 0.221 mSv

Limits to keep in mind

Small single-center retrospective series of 40 procedures with a mobile C-arm and no comparison group; dosimeters were worn by patients, so operator dose was not directly measured.
