Evaluation of the incidence of complications after transsphenoidal hypophysectomy in cats and the possible relation to the tumor size

Abstract

This retrospective study evaluates the incidence of post-operative complications in 48 cats undergoing transsphenoidal hypophysectomy at the University Clinic for Companion Animals in Utrecht between January 1994 and December 2020. It aims to determine if a correlation exists between tumor size and the severity of these complications. Pre-operative data included tumor size measured by CT or MRI scans, and various clinical parameters. Post-surgical data encompassed survival, diabetes status, hospital stay duration, insulin dosage, and hematological values. The findings reveal no significant correlation between tumor size and post-operative complications, such as admission time, diabetes, electrolyte concentrations, and wound dehiscence. Although larger tumors were hypothesized to cause more
