Survival of Dogs with Bilateral Phrenectomy and Extensive Transection of Intercostal Nerves

Abstract
Eight grown dogs were subjected to bilateral phrenectomy during a single operation. In most of these dogs intercostal nerves were extensively severed some days or weeks following phrenectomy. Completeness of phrenectomy was checked by electrical stimulation and histological examination of the severed nerves. All animals survived the phrenectomies and intercostal sections to the extent of leaving only the upper 3 pairs of intercostal nerves intact. This work is in contrast to a recent report stating that dogs will not survive after bilateral phrenectomy, and substantiates earlier work on the effects of this procedure.
