“…8 Closure may be accomplished via surgical occlusion, use of hemostatic clips, or transcatheter embolization. 2,4,6,[8][9][10][11] If the DA is successfully occluded, it has been posited that heart size may return to normal dimensions and the mitral valve may again become competent. 6 Surgical occlusion yields the best results, in terms of survival rates and minimizing postoperative complications, when the occlusion procedure is performed as soon as possible after diagnosis.…”

“…Los animales no tratados usualmente padecen de insuficiencia cardiaca congestiva izquierda y edema pulmonar y muere entre el 54 y el 70 % antes del primer año de vida (5,9,17,23), por esta razón se recomienda el cierre del ducto a temprana edad (9).…”

“…Este seguimiento ecocardiográfico con Doppler no fue realizado en la paciente, lo cual no permite descartar la presentación de flujo residual en ella. El flujo residual es mayor en pacientes con cierre por transcatéter (9). La recanalización del ducto oscila entre 1 a 3 % de los pacientes (7,9,25) y se desarrolla entre 6 semanas y 37 meses postoperatorio (7); a pesar de que la paciente se encontraba clínicamente sana, dos meses después de la cirugía, en este caso no fue posible evaluar la presencia de esta complicación u otras complicaciones debido a que la paciente no volvió a asistir a la clínica y no se logró entablar comunicación con sus propietarios.…”

ResumenEl presente artículo reporta el caso de una hembra canina cocker spaniel entera de dos meses de edad, que fue llevada a la Clínica para Pequeños Animales de la Universidad Nacional de Colombia, con tos de seis días de evolución, poca ganancia de peso e historial de soplo cardiaco detectado con anterioridad en un centro veterinario. Tras realizar el examen médico, se perciben estertores en ambos campos pulmonares, aumento del reflejo tusíge-no, pulso yugular positivo, un soplo cardiaco 6/6 y aumento del tiempo de llenado capilar. Se diagnostica la persistencia de ducto arterioso mediante ecocardiografía, por lo cual se plantea la ligadura del ducto como tratamiento definitivo. La paciente se recuperó satisfactoriamente del procedimiento quirúrgico sin tener ningún tipo de complicación; en el postoperatorio presentó tos que se resolvió a los pocos días con ayuda de un tratamiento con furosemida (2 mg/kg TID IM). Tres meses después de realizarse el procedimiento quirúrgico la paciente se encontraba clínicamente sana, sin ninguna manifestación de origen cardiaco.Palabras clave: ducto arterioso persistente, canino, ligadura, poliéster trenzado. Persistent ductus arteriosus ligation in a two-months-old cocker spaniel: A case report AbstractThis article reports the case of a two-months-old female cocker spaniel, who was taken to the Clinic for Small Animals at the Universidad Nacional de Colombia, with a cough of six days of evolution, poor weight gain, and a history of heart murmur detected previously in a veterinary center. A medical examination evidenced crackles in both lung fields, increased cough reflex, positive jugular pulse, a 6/6 heart murmur, and increased capillary refill time. Persistent ductus arteriosus was diagnosed by echocardiography; for this reason, ductus ligation was suggested as definitive treatment. The patient satisfactorily recovered from the surgical procedure without any complications; she presented postoperative cough that resolved within a few days with the help of a treatment with furosemide (2 mg/kg IM TID). Three months after the surgical procedure, the patient was clinically healthy, without any symptom of cardiac origin.

“…PDA has been traditionally treated via surgical ligation, in which the chest cavity of the dog is opened via thoracotomy and the ductus is ligated (Birchard et al, 1990; Eyster, 1976; Jackson and Henderson, 1979; Nguyenba and Tobias, 2008). While effective, surgical ligation is invasive, and carries non-trivial operative risks including, nonfatal hemorrhage, pneumothorax, and chylothorax as reported in 11–15% of cases (Bureau et al, 2005; Goodrich et al, 2007; Stanley et al, 2003; Van Israel et al, 2002) and operative mortality in up to 11% of cases (Birchard et al, 1990; Bureau et al, 2005; Eyster, 1976; Goodrich et al, 2007; Stanley et al, 2003; Van Israel et al, 2002). These complications motivate the development of improved minimally invasive closure techniques (Tobias and Stauthammer, 2010).…”

Patent ductus arteriosus (PDA) is a congenital cardiovascular defect in which a fetal connection between the aorta and pulmonary artery does not spontaneously close shortly after birth. If left uncorrected serious complications and even death can occur. Surgical ligation is the traditional treatment method; however, it is an invasive procedure, that motivates development of a minimally invasive option. Shape memory polymer (SMP) foams are unique materials that hold promise in the field of minimally invasive occlusion devices. In this work, a prototype nitinol foam cage (NFC) incorporating SMP foams has been designed and evaluated in multiple mechanical and in vitro verification tests. The NFC demonstrated acceptable fatigue resistance in a preliminary strut integrity test, withstanding one million cycles without complete strut fracture. Radial force analysis of both thick- and thin-walled prototype variations generated less vessel distension and wall tension in a vessel mimic compared to a commercial device. The NFCs exhibited negligible in vitro migration, comparable to that of a commercial device, using simplified, ideal models of PDA. Deployment characteristics of the prototypes were evaluated and compared to that of a commercial device when delivered into physiological models of PDA. During mock deployments, a veterinary cardiologist noted that, while deliverable, the thin-walled NFC prototype exhibited poor deployment characteristics, however the thick-walled NFC had deployment characteristics comparable to that of a commercial device. The promising results of this study warrant further investigation of the NFC device for canine PDA closure.

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

Abstract: Ideal PDA closure should result in no residual ductal flow to prevent possible adverse long-term sequelae, such as recanalization and infective endocarditis.
