To the Editor.—In their Contempo article, Drs Gordon and Levin1 published data for the target artery length for temporal artery biopsy specimens. I assume that they are recommending that a surgeon obtain a temporal artery segment that is at least 20 mm in length in situ. Smooth muscle retraction followed by formalin fixation may shorten such a surgical specimen. Do the authors have data on the degree of shrinkage in a processed temporal artery biopsy? (Most pathologists assume that formalin fixation that will cause a 10% reduction in the length of a nonbony structure, but documentation is hard to come by.) Alternatively, if a 2-cm-long portion of formalin-fixed artery is recommended, what is the recommended artery length that should be obtained? Without clarification, I fear that some surgeons will be called to task because of a lack of understanding of tissue-processing artifacts.
