Blood pressure and heart rate during ovariohysterectomy in pyometra and control dogs: a preliminary investigation.
Acta veterinaria Scandinavica, 2016Co-Authors: Odd V. Höglund, Johanna Lövebrant, Ulf Olsson, Katja HöglundAbstract:Surgery causes a stress response, a physiologic response to trauma. The intraoperative surgical stress response in dogs diagnosed with pyometra has not previously been described. The aim of this study was to investigate the intraoperative surgical stress response, assessed by blood pressure and heart rate measurements, in dogs diagnosed with pyometra and healthy controls. All dogs were premedicated with acepromazine and methadone, anaesthesia was induced with propofol and maintained with isoflurane, where after the dogs were subjected to ovariohysterectomy. Eight dogs diagnosed with pyometra and eight healthy controls were used. Systolic blood pressure and heart rate were measured to assess the surgical stress response. Additionally propofol dosage at induction of anaesthesia and the end-tidal isoflurane concentration were investigated. The surgery was split into four phases. Phase 0 was the period 10 min before the skin incision, phase 1 was skin incision and opening of abdomen, phase 2 was manipulation of uterine horns, lifting of the ovary with stretching of the Mesovarium, ligation and transection of Mesovarium and phase 3 was ligation and transection of cervix, removal of organs and closing of the abdomen. Dosage of propofol at induction of anaesthesia was 3.6 ± 1 mg/kg in dogs with pyometra and 4.1 ± 1 in healthy controls (P = 0.37). In both groups, systolic blood pressure increased between phase 1 and 2, from 87 ± 15 to 114 ± 19 mmHg in dogs with pyometra, and from 88 ± 18 to 106 ± 20 mmHg in healthy controls, (both P

Ligation of the Mesovarium in dogs with a self-locking implant of a resorbable polyglycolic based co-polymer: a study of feasibility and comparison to suture ligation
BMC Research Notes, 2016Co-Authors: Matheus Roberto Mota Costa, André Lacerda Abreu Oliveira, Renato Moran Ramos, Leonardo Waldstein Moura Vidal, Niklas Borg, Odd V. HöglundAbstract:Background Ligation of the Mesovarium in female dogs may be cumbersome with risk of complications and is associated with intense noxious stimuli. A resorbable implant, a self-locking loop designed for surgery, was developed as an alternative to traditional ligation. The study aimed to test the feasibility of ligating the canine ovarian pedicle with the implant and to compare its performance to traditional suture ligation. Results In total 45 intact female dogs destined for elective ovariohysterectomy and adoption were included. In 21 dogs the new resorbable implant was used to ligate the Mesovarium, and in 24 control dogs traditional suture was used with one encircling ligature. Mean weight of implant dogs was 10.7 ± 5.6 kg (range 3.5–22.0), and mean weight of control dogs was 12.8 ± 6.4 kg, (range 4.1–27.0). The body weight of dogs did not differ between groups (P = 0.25). In total, 42 ovarian pedicles were successfully ligated with the implant. In one control dog, intraoperative haemorrhage from the left ovarian pedicle was diagnosed. The Mesovarium was re-ligated and haemostasis was confirmed. All dogs recovered uneventfully. The ligation time of the Mesovarium was significantly shortened (P = 0.02) by using the self-locking implant versus a single ligature (3′28′′ ± 1′05′′ and 5′29′′ ± 3′54′′, respectively). Total duration of surgery differed between the groups (P = 0.02) with a shortened duration of surgery when using the self-locking implant (15′56′′ ± 2′47′′ and 20′39′′ ± 8′58′′, study group versus control group, respectively). In both groups, duration of surgery and time required to ligate the ovarian pedicle were longer in larger dogs than smaller dogs. Conclusion The results of this feasibility study suggested the implant can be used to ligate the canine Mesovarium. Compared with traditional suture ligation, the results suggested that time to ligate the ovarian pedicle and duration of surgery were significantly reduced with the implant. More time was required to perform surgeries in larger dogs.

A Testosterone-Producing Tumour in the Mesovarium
Pathology research and practice, 1991Co-Authors: G. Van Ingen, J. Schoemaker, Jan P. A. BaakAbstract:Summary An androgen-secreting adnexal tumour is presented. The tumour was a steroid cell tumour of the Mesovarium, without crystals of Reinke, hence the diagnosis was a steroid cell tumour (lipid cell tumour), not otherwise specified (in this case, because of its location in the Mesovarium, an adrenal rest tumour). The clinical presentation, diagnosis, prognosis and differential diagnosis of virilizing adnexal tumours are discussed.
