Intraoperative Hemorrhage During Patent Ductus Arteriosus Ligation in Dogs

Abstract

The technique described in this report permits simple ligation of a range of different ductus morphologies in dogs of varying breeds, weights, and ages. In the event of serious hemorrhage, prompt ventricular outflow occlusion and ductus ligation followed by rapid whole blood transfusion is life saving in most cases.

Evaluation of survival rate and prognostic indicators for surgical treatment of left-to-right patent ductus arteriosus in dogs: 52 cases (1995–2003)

“…6,13,15,16,27 The perisurgical mortality rate in dogs in our study was 0%, despite the occurrence of acute intraoperative bleeding in 8 dogs. Surgeries were performed by experienced surgeons, which contributes to lower surgical mortality rates.…”

“…In our study, none of the dogs that had acute intraoperative hemorrhage died in the first 5 days after surgery, although early deaths were reported by Birchard et al 13 Different techniques have been recommended to control bleeding at the time of dissection or ligature of the DA. 27,28 Limitations of our study include the retrospective design, which makes investigators dependent on the details included in records, especially those concerning complementary examinations before and after surgery. Echocardiographic results would have provided more accurate information regarding cardiac function in the dogs.…”

Comparison of the Incidence of Residual Shunting Between Two Surgical Techniques Used for Ligation of Patent Ductus Arteriosus in the Dog

“…It is a commonly reported congenital cardiac defect 1–6 . PDA is more common in purebred dogs than mixed breeds, 2,7,8 but reported breed dispositions show definite geographic variations 1–3,6–10 . Female dogs are at greater risk for developing PDA 1,2,4,5,8,10 .…”

Perioperative red blood cell transfusion requirement for various surgical procedures in dogs: 207 cases (2004–2013)

“…12,13 If our study population contained a greater number of dogs that underwent cardiovascular procedures, intrathoracic procedures could have been analyzed in subcategories rather than as a single group. This was because preliminary statistical analysis comparing the need for transfusion and survival rate among intrathoracic procedures revealed that there were no significant differences among specific procedures within this category.…”
