A persistent superior vena cava sinistra in the cat transmitting coronary blood

Abstract

a study of the literature of this form of variation was undertaken, the results of which are here given.This anomaly was found in a young and apparently normal cat. Upon opening the thoracic cavity, a long slender vein, of uniform diameter, was exposed, which reached from the left innominate vein to the coronary sinus, about 4 mm. distant from its atrial end. This was recognized as a left superior vena cava .The coronary veins were all of normal size and distribution, and their openings into the coronary sinus were normal. But, the coronary sinus ended blindly about 5 mm. short of the point at which it should have opened into the right atrium. At this end of the sinus it received the vena cordis media. No remnant of a connection could be found upon the blind sinus end or the right atrial wall. Upon tracing the anomalous vena cava upward it was found to open into the left innominate vein at the point where this vein joined with the right to form the normal superior vena cava ( fig. 1). In the upper third of its extent the left superior vena cava received the superior intercostal vein, which was composed of two intercostal branches.Upon examining the interior of the right atrium, no trace of an opening of the coronary sinus was seen. However, the wall 45

Is Surgical Ligation of an Accessory Left Superior Vena Cava Always Safe?

“…The association of ostial atresia of the coronary sinus with LSVC was reported by Grant [3] in 1917 in a cat. Harris et al (1927) were the first to report autopsy findings on a 22-month-old boy with complete transposition and an LSVC draining the blind coronary sinus.…”

Case report: A novel occurrence of persistent left cranial vena cava coexisting with polycystic kidney disease in a cat

“…In humans and dogs, PLCVC is sometimes found incidentally during echocardiography, central venous catheterization, and surgical procedures ( 2 , 6 , 8 , 18 , 19 ). The available literature on cats primarily focuses on their anatomical characteristic ( 1 , 20–24 ), with limited reports on its effects on the heart based on echocardiographic features or disease progression. In this case, a diagnosis of PLCVC was established during a cardiac ultrasound, prompted by tachycardia and the presence of cardiac murmurs.…”
