Ipsilateral decubitus position for percutaneous CT-guided adrenal biopsy

Area of Science:

• Radiology
• Interventional Radiology
• Surgical Oncology

Background:

• Percutaneous adrenal biopsy is crucial for diagnosing adrenal lesions.
• Traditional prone positioning may be limited by lung interference.
• Alternative patient positioning is needed to optimize safety and efficacy.

Purpose of the Study:

• To evaluate the efficacy and safety of the ipsilateral decubitus position for percutaneous adrenal needle biopsy.
• To determine if this position facilitates a direct posterior approach without lung traversal.

Main Methods:

• Patients were positioned in the ipsilateral decubitus position for adrenal biopsy.
• The technique focused on elevating and immobilizing the dependent diaphragmatic leaf.
• A direct posterior approach was utilized to access adrenal lesions.

Main Results:

• The ipsilateral decubitus position successfully allowed percutaneous adrenal needle biopsy in four cases.
• This positioning avoided traversing lung tissue, a common complication.
• Immobilization of the diaphragm enhanced the accuracy of needle placement.

Conclusions:

• The ipsilateral decubitus position is a safe and effective alternative for percutaneous adrenal needle biopsy.
• This technique is particularly useful when lung tissue obstructs a direct posterior approach.
• Improved diaphragmatic stability contributes to precise needle targeting in adrenal interventions.
