There is an ideal temporal artery biopsy length after all.

Purpose
Temporal artery biopsy(TAB) is the most accurate modality of diagnosis for Giant Cell Arteritis(GCA).Due to segmental nature of GCA, it is important to obtain a sufficient length of the specimen ,to determine an accurate diagnosis of this sight-threatening condition. Literature suggests aiming for biopsy of>2cm to account for a possible shrinkage of the sample. This study determines the amount of reduction in length in-situ and when it is received by pathology in real-life terms.
Methods
22 consecutive TABs were carried out at James Cook University Hospital, Middlesbrough as part of diagnosis of GCA. Patient demographics, measurements of the initial skin incision, the temporal artery distance between ties, the estimated length of specimen in-situ and the length of the sample measured prior to histological analysis were recorded.
Results
There were 22 samples in this study. Mean age of the patients was 71(SD=11.6mm).27% of the TABs were proven to be GCA on pathology. The mean skin incision measurement was 43.9mm(SD=12.8mm). The mean TAB measurement between the sutures ties prior to sample being excised was 19.3mm(SD=5.5mm). The estimated length of specimen in-situ was 16.5 mm(SD=5.6mm). Interestingly, the average TAB sample size of the same samples, measured prior to histological analysis was 11mm(SD=7.3mm).Therefore, the difference between samples measured by histologist prior to analysis and the measurement of the same samples in-situ demonstrates 5.5mm(33%)length reduction.
Conclusion
Our study demonstrated a significant reduction in the length of TAB sample size available for histological analysis following excision, highlighting the importance of ensuring that the sample size is as long as possible in order to ensure the most accurate result of TAB. This, however, may be limited by practicality of the artery available for sampling.
