VALIDAÇÃO DE TÉCNICA HEMOSTÁTICA DO COMPLEXO ARTERIOVENOSO OVARIANO NA OVARIOSALPINGOHISTERECTOMIA DE GATAS

Abstract

The present study aimed at describing ovarian arterial venous complex (OVAC) obliteration technique consisting in tying a knot over its own axis. It also aimed at evaluating the efficacy of this hemostatic technique in queens ovariosalpingohisterectomy, as well as checking partial OVAC obliteration time and total procedure time. After previous training – based on alternative methods – for the demanded surgical skills acquisition, in vivo surgical procedures were conducted. Once gathered the necessary skills, an experimental study was carried in order to compare this technique with the linking technique in which three hemostatic clamps are used. In vivo training, firstly applied in healthy queens, and later in uterine affection carriers, helped consolidating the dexterity previously acquired through alternative practice methods, and also contributed to the feasibility verification of the described technique, which showed to be effective. Comparative study did not reveal any significant statistic difference between both groups on total surgical elapsed time (p=0.2848) and time spent for the right OVAC obliteration (p=0.1036), however significant difference was observed on the left OVAC obliteration (p=0.0001). The results obtained during transoperatory observation led to the conclusion that the described technique is feasible and provides appropriate OVAC hemostasis.
