Ultrasound-guided percutaneous splenic biopsy using an 18-G core biopsy needle: our experience with 52 cases

摘要

Objective: The spleen is more commonly affected in multiorgan disease, but alternative sites are selected for biopsy owing to perceived haemorrhage risk. If these sites are inaccessible or, less commonly, the spleen is the only disease site, then splenic biopsy is considered, with most studies using a 20-to 22-G needle. The primary aim of biopsy is to exclude underlying malignancy or to obtain histological analysis in known malignancy, usually lymphoma, when reclassification is required for therapy. We present, to our knowledge, the largest series of 18-G ultrasound-guided splenic core needle biopsy assessing diagnostic and complication rates.
