Image-guided percutaneous splenic biopsy and drainage

Area of Science:

• Interventional Radiology
• Diagnostic Imaging
• Abdominal Surgery

Background:

• Percutaneous splenic interventions are crucial for diagnosing and managing splenic pathologies.
• Splenectomy carries significant morbidity and mortality, necessitating less invasive alternatives.
• Image guidance is essential for the safety and efficacy of splenic procedures.

Purpose of the Study:

• To evaluate the safety and accuracy of percutaneous splenic biopsy and drainage.
• To compare the outcomes of fine-needle aspiration cytology versus core needle biopsy for splenic tissue sampling.
• To assess the role of imaging modalities in guiding these procedures.

Main Methods:

• Review of percutaneous splenic biopsy and drainage procedures.
• Analysis of complication rates and diagnostic accuracy.
• Comparison of fine-needle aspiration cytology and core needle biopsy techniques.
• Utilization of computed tomography and ultrasound for image guidance.

Main Results:

• Percutaneous splenic biopsy and drainage are safe and accurate, with a major complication rate of 1.3%.
• The complication rate is comparable to other intra-abdominal organ biopsies and lower than splenectomy.
• Core needle biopsy demonstrated superior diagnostic accuracy compared to fine-needle aspiration cytology.
• Both CT and ultrasound are effective for image guidance.

Conclusions:

• Percutaneous splenic biopsy and drainage are safe, accurate, and less invasive alternatives to splenectomy.
• Core needle biopsy is recommended for higher diagnostic yield, while fine-needle aspiration offers a better safety profile.
• Image-guided percutaneous techniques are valuable tools in the management of splenic conditions.
