AbstractDuring routine dissection for undergraduate students, two venous end cardiac anomalies were noted In a male cadaver, in addition to a normal right sided superior vena cava, a persistent left superior vena cava (PLSVC) was seen opening into the right atrium via coronary sinus. Left brachiocephalic vein was of a small caliber. In addition, left atrium showed only two pulmonary ostia. No other cardiac anomalies were found Both these anomalies rarely cause any haemo-dynamic compromise and hence may remain asymptomatic throughout life. They are usually found as a chance finding during imaging studies or in post mortem studies as was seen in this case. However, both are known to be associated with cardiac arrhythmias. Their concomitant occurrence suggests a common timing of their development and / or a common causative agent that halted their development. Knowledge of these anomalies is invaluable for the cardiac surgeons and interventionists.

Anomalous Pulmonary Venous Connection

Cor triatriatum may be associated with abnormalities of pulmonary venous anatomy. This case report describes a unique form of partial anomalous pulmonary venous connection. The patient presented at 5 weeks of age with symptoms of tachypnea and poor feeding. Echocardiography demonstrated cor triatriatum and partial anomalous pulmonary venous drainage of the right upper lung. The patient underwent urgent repair of cor triatriatum. It was elected to not address the partial anomalous pulmonary venous connection at that time. The patient returned at age 19 months for elective repair of the anomalous pulmonary venous connection. There was also a large vein connecting the right lower pulmonary veins to the superior vena cava. This was repaired by dividing the superior vena cava along a vertical axis to redirect the flow of the anomalous pulmonary veins through the connecting vein to the left atrium. This report describes the anatomy and surgical approach to a unique form of anomalous pulmonary venous connection.

Background: Presented is a case of persistent left superior vena cava draining into the right atrium through coronary sinus and finally opens into right atrium. Abnormalities of the vascular system are more commonly seen due to its importance in circulation. Persistent left superior vena cava is rare but important congenital vascular anomaly. It results when the left superior cardinal vein caudal to the innominate vein fails to regress.The venous anomaly of a persistent left superior vena cava (PLSVC) affects 0.3%–0.5% of the general population. Normally the superior vena cava is a single vascular structure formed by the union of right and left brachiocephalic veins which are in turn formed by the union of internal jugular and subclavian veins of corresponding side, draining the head and neck as well as the superior extremity. Aims and Objective: To evaluate the accuracy of persistent left superior vena cava and to find out the opening of PLSVC and formations of both SVC. Materials and Methods: During routine dissection of Thorax, we have opened the thoracic cage and take out the Heart. during that we found separate SVC and then we did the study on this PLSVC in the Department of Anatomy, Jaipur National University Institute for Medical Sciences and Research Centre (JNUIMSRC) Jaipur and National Institute of Medical Sciences and Research (NIMS & R). Results: We found persistent left superior vena cava in two cadavers out of 30 cadavers (6.66%) one was 64-year-old male cadaver and another 72-year-old male cadaver. Both the vena cavae were formed as of brachiocephalic veins of the corresponding side. The persistent left superior vena cava opened into the enlarged coronary sinus that drained into the right atrium between the opening of inferior vena cava and right atrio-ventricular orifice. Conclusion: It has important clinical implications in certain clinical interventions. It may complicate placementof cardiac catheters or pacemaker leads.

Venous Pulse

Internal jugular veins (IJVs) are the largest veins in the neck and are considered the primary cerebral venous drain for the intracranial blood in supine position. Any reduction in their flow could potentially results an increase in cerebral blood volume and intracranial pressure (ICP). The right internal jugular vein communicates with the right atrium via the superior vena cava, in which a functional valve is located at the union of the internal jugular vein and the superior vena cava. The atrium aspiration is the main mechanism governing the rhythmic leaflets movement of internal jugular vein valve synchronizing with the cardiac cycle. Cardiac contractions and intrathoracic pressure changes are reflecting in Doppler spectrum of the internal jugular vein. The evaluation of the jugular venous pulse provides valuable information about cardiac hemodynamics and cardiac filling pressures. The normal jugular venous pulse wave consists of three positive waves, a, c, and v, and two negative waves, x and y. A normal jugular vein gradually reduces its longitudinal diameter, as described in anatomy books; it is possible to segment IJV into three different segments J3 to J1, as it proposed in ultrasound US studies and CT scan. In this review, the morphology and methodology of the cerebral venous drainage through IJV are presented.

ABSTRACT Anomalous pulmonary venous drainage is the anomalous drainage of one or more than one pulmonary vein draining into right atrium, superior vena cava, inferior vena cava, coronary sinus, or innominate vein. Right-sided pulmonary vein anomalous drainage is usually associated with sinus venosus type atrial septal defect. Pericardial patch repair and rerouting of the right pulmonary vein are commonly performed operations for such cases. These operations involve a risk of obstruction to the flow of superior vena cava or rerouted pulmonary vein in the postoperative period. The defects are well visualized on the transesophageal echocardiography (TEE). We are reporting three cases operated for anomalous drainage of right-sided pulmonary vein, highlighting the perioperative echocardiographic features.

Abstract Introduction We present a case of dual drainage of the right upper lobe of the lung into the left atrium and via partial anomalous venous pulmonary return (PAPVR) into a persistent left superior vena cava (SVC). Discussion It is only in the minority of PAPVR cases where the anomalous pulmonary veins cross the midline. We provide a review of current literature on this topic and an explanatory embryological model. Knowledge of embryonic development and possible anatomic variations, including the concept of dual venous drainage of the lung, leads to better interpretation of imaging, with more accurate description of the morphology at hand. High-resolution multidetector computed tomography (MDCT) helps to delineate the exact vascular anatomy. This will enhance a better understanding of and anticipation on the patient’s disease status, with more accurate planning of intervention, and possibly less complications.

AbstractAbnormalities of the vascular system are always of extreme interest due to its importance in circulation. Normally the superior vena cava is a single vascular structure formed by the union of right and left brachiocephalic veins which are in turn formed by the union of corresponding internal jugular and subclavian veins, draining the head and neck as well as the superior extremity. However during routine dissection in the Department of Anatomy, Kasturba Medical College, Manipal, we came across a case of double superior vena cava with persistent left superior vena cava in a 58-year-old male cadaver. Both the vena cavae were formed as continuations of brachiocephalic veins of the corresponding side. The persistent left superior vena cava opened into the enlarged coronary sinus that drained into the right atrium between the opening of inferior venacava and right atrioventricular orifice. No communication was observed between the two vena cavae. A persistent left superior vena cava does not by itself produce any physiological derangement. But it has important clinical implications in certain clinical interventions. It may complicate placement of cardiac catheters or pacemaker leads. Awareness of this anomaly may therefore reduce confusions and thus would help to avoid further complications.

There has been an increase in the use of central venous catheters (CVCs) in clinical practice. One of the most dangerous complications associated with their use is symptomatic or asymptomatic thrombosis (T), sometimes associated with superior vena cava (SVC) syndrome, resulting from impaired venous drainage. The right heart clots can induce an increased risk of mortality due the potential pulmonary embolism (PE). We report a case of asymptomatic 83-year-old woman in whom the thrombosis was detected after an echocardiogram. Echocardiography demonstrated a cardiac mass, and the T was confirmed by (magnetic resonance imaging) MRI. The clinical scenario, a high index of suspicion and routine use of echocardiogram in patients with CVC, can lead to a correct diagnosis, preventing dangerous complications.

Central Vein Stenosis

Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma. A case of left brachiocephalic vein stenosis due to the insertion and function of a temporary right subclavian hemodialysis catheter is presented. The purpose of the manuscript is to emphasize that, with the introduction of a temporary subclavian hemodialysis catheter via the right subclavian vein apart from causing concurrent stenosis/infarction of the right subclavian and right brachiocephalic vein, it is also possible to cause stenosis of the left brachiocephalic vein (close to its contribution to the superior vena cava) although the catheter tip is placed in the correct anatomical position in the superior vena cava.
