Abnormal Superior Yena Caya. 



By Professor A. C. Geddes, Royal College of Surgeons in Ireland. 



With 4 Figures. 



A specimen of interest, illustrating one of the rare vascular ab- 

 normalities was recently obtained in the dissecting room of the 

 Royal College of Surgeons in Ireland. It occurred in the body of a 

 senile male who died in the workhouse infirmary. Age and history 

 are alike unobtainable but the body had the appearance of that of a 

 man of not less than 70 years and was well nourished. In the 

 specimen four right pulmonary veins open, below the level of entrance 

 of the vena azygos major, into the superior vena cava which in turn 

 oj)ens by a wide funnel shaped orifice equally into the right and 

 left auricles. The inter-auricular septum has a free crescentic upper 

 margin which stretches across the mouth of the vein and must in 

 life have divided the blood stream so that approximately equal volumes 

 of blood were delivered into each of the auricles. The heart other- 

 wise is normal. There is a small valvular opening at the site of the 

 foramen ovale such as is found in approximately 30 ^ of subjects 

 examined (1). The tricuspid valve is healthy. The pulmonary artery 

 is large but not unduly so when the age of the individual is con- 

 sidered. The left auricle receives one right and two left pulmonary 

 veins ; the mitral valve is normal. The aorta is normal. The heart 

 and great vessels are shown in Fig. 1. 



Veins emerging from the right lung and opening into the superior 

 vena cava are recurrently met with. Such veins are of two types : 

 true pulmonary veins; and false "pulmonary veins". The false may 

 be considered first.
