- Abstract
Purpose: The purpose of this audit was to determine the success and complication rates from computed tomography (CT)-guided transthoracic percutaneous needle biopsies (PNBs) in a tertiary referral centre and compare these with the Society of Interventional Radiology (SIR) standards of practice. Materials and methods: Using the Picture Archiving and Communication System (PACS), all CT-guided transthoracic PNBs were isolated at St. Joseph's Healthcare Hamilton (SJHH) for the year of 2010. Reports, images, or both, were reviewed to determine lesion size, lesion site, needle size, number of core biopsies obtained, and complication rates. Post biopsy chest radiograph reports, images, or both, were reviewed in some cases. Pathology, microbiology, and surgical reports were also reviewed. Complication and diagnostic rates were then compared with published SIR standards of practice. Results: Two hundred and fifty-eight CT-guided transthoracic PNBs were performed at SJHH in 2010, of which 224 (86.8%) were successful. One hundred and twenty nine (50.0%) had minor complications, while none resulted in major complications. Thirtytwo (12.4%) biopsies were non-diagnostic. Five (1.9%) non-diagnostic biopsies were shown to be malignant by repeat biopsy or surgery. Two (0.8%) biopsies showed benign tissue but were proven malignant by repeat biopsy or surgery. Conclusion: CT-guided transthoracic PNB is a safe and effective technique to obtain tissue diagnosis, however regular audits are necessary to improve outcomes and minimize complications.
