Síncope neurocardiogênica em cão com doença valvular crônica de mitral - Relato de caso / Neurocardiogenic syncope in a dog with chronic mitral valvular disease - Case report / Síncope neurocardiogénico en perro con enfermedad valvular mitral crónica - Relato de caso

A doença valvular crônica de mitral é a enfermidade cardíaca mais comumente relatada em cães de pequeno e médio porte, adultos ou idosos. A síncope cardíaca é uma manifestação comumente observada, causada por diversos mecanismos. Objetivou-se relatar um caso desta doença em uma cadela da raça Teckel, com 16 anos de idade, que apresentava episódios recorrentes de síncope. Os episódios estavam associados com bradicardia, palidez de mucosas e aumento da pressão intratorácica. Excluindo-se outras causas de síncope, foi realizado o diagnóstico presuntivo de síncope neurocardiogênica, sendo a primeira descrição na medicina veterinária.(AU)

Chronic mitral valvular disease is the most commonly acquired heart disease in middle-aged to elderly dogs in small to medium-size breeds. Cardiac syncope is a common manifestation observed in such disease, caused by several mechanisms. The purpose of this study is to report a case of several syncope episodes in a Teckel dog aged 16 years, presenting chronic mitral valvular disease. The episodes were associated with bradycardia, pale mucous membranes and increased intra-thoracic pressure. The presumptive diagnosis of neurocardiogenic syncope was reached by excluding other causes of syncope, which is the first description in veterinary medicine.(AU)

Laparoscopic correction of experimentally induced diaphragmatic rupture in dogs

To describe the dog as a model for studying laparoscopic correction of experimental diaphragmatic ruptures. Five male dogs were used in this study. Under laparoscopic approach, a defect of 7cm was created on the left ventral insertion of the diaphragm. Fourteen days after this procedure, the abdomen was explored using laparoscopic access and the diaphragmatic defect was corrected with intracorporeal suture. The dislocated organs, surgical time, and suturing time were recorded. Analgesia and clinical condition were monitored during the postoperative period.RESULTS:All animals recovered well from the diaphragmatic rupture creation. After 14 days, abdominal organs (liver, spleen, omentum and/or intestine) were found inside the thoracic cavity in all animals. It was possible to reposition the organs and suture the defect by laparoscopic access in three animals. These animals showed excellent postoperative recovery. It was not possible to reposition the liver safely when it was friable. Laparoscopic creation of diaphragmatic rupture in dogs is feasible. Dogs are a good model for training and studying the correction of experimentally created diaphragmatic rupture by the laparoscopic approach. A friable liver is a complicating factor that should be taken into account. Animals submitted to laparoscopic correction showed excellent postoperative recovery.(AU)
