Summary
Transvenous biopsies using intravascular ultrasound enable targeted sampling of difficult-to-reach lesions. This image-guided technique offers a viable alternative for percutaneous biopsies when location or depth poses challenges.
Area of Science:
- Interventional Radiology
- Medical Imaging
- Ultrasound Technology
Background:
- Image-guided biopsies are common radiological procedures.
- Percutaneous sampling is not always feasible due to lesion location or depth.
Purpose of the Study:
- To present a technique for transvenous biopsies using intravascular ultrasound.
- To demonstrate the feasibility of this method in clinical practice.
Main Methods:
- Utilized intravascular ultrasound for direct visualization of lesions.
- Employed principles of non-targeted transvenous solid organ biopsy.
- Performed targeted transvenous biopsies of solid organ and perivascular lesions.
Main Results:
- Successfully performed targeted transvenous biopsies.
- Demonstrated direct visualization and sampling of challenging lesions.
- Presented three illustrative case examples.
Conclusions:
- Transvenous biopsy with intravascular ultrasound is an effective technique.
- This method expands the capabilities of image-guided biopsy for difficult lesions.
