Summary
Percutaneous ethanol injection (PEI) via a transthoracic approach is a safe and effective method for targeting the subphrenic liver region in rats. Minor complications resolved quickly, demonstrating the procedure
Area of Science:
- Veterinary Medicine
- Interventional Radiology
- Surgical Techniques
Background:
- Percutaneous ethanol injection (PEI) is a common treatment for liver lesions.
- Accessing the subphrenic region of the liver can be challenging.
- Transthoracic approaches offer an alternative route for liver interventions.
Purpose of the Study:
- To evaluate the safety and efficacy of a transthoracic approach for PEI in the subphrenic liver region of rats.
- To assess the complication rate and resolution following this technique.
Main Methods:
- Fourteen normal rats underwent PEI in the subphrenic liver region using a 22G needle via a transthoracic approach.
- Procedure success and complications were monitored.
- Follow-up CT scans were performed one week post-procedure.
Main Results:
- The transthoracic PEI procedure was successful in all fourteen rats.
- Three rats experienced minor complications: pneumothorax, hemorrhage, and pleural effusion.
- All observed complications resolved completely by the one-week follow-up CT scan.
Conclusions:
- The transthoracic approach is a useful and safe method for performing PEI in the subphrenic region of the liver in rats.
- This technique demonstrates a low rate of transient complications.
- Further studies may explore its applicability in clinical settings.
