Pelvimetria radiográfica em cadelas: estudo retrospectivo de distocia em cadelas atendidas no Hospital Veterinário Prof. Ivon Macêdo Tabosa da Universidade Federal de Campina Grande.

Abstract

Dystocia occurs when there is difficulty in expelling the fetuses and is considered a critical situation in veterinary clinics, and it is extremely important that it is identified quickly. Among the causes of this condition in dogs, obstructive dystocia stands out, caused by the disproportion between the maternal pelvis and the fetus and the physiological changes caused by the use of contraceptives. Thus, the objective was to characterize the profile of female dogs with dystocia treated at the Prof. Ivôn Macedo Tabosa University Veterinary Hospital between 2019 and 2023 and to evaluate the applicability of the method of analysis of pelvic proportions called radiographic pelvimetry. For this purpose, the clinical history of 32 female dogs with gestational age greater than 50 days was analyzed, emphasizing age, breed, previous gestational history, use of contraceptives and treatment performed. Radiographic pelvimetry consisted of measuring pelvic diameters through radiographs of female dogs to analyze the proportions, namely: hip diameter (CD), transverse diameter (DT), acetabular diameter (DA) and lateral ischial diameter (LID). The results found allowed us to outline the profile of the female dogs treated that presented dystocia, characterized as primiparous SRD females with an average age of 1 year who used contraceptives and suggest the effectiveness of the radiographic pelvimetry method as a preventive alternative that can be performed during the gestational monitoring of female dogs, enabling the evaluation of their reproductive aptitude for eutocic or dystocic delivery.
