This paper considers abnormalities of flow patterns in the flow patterns in the cervical vasculature due to varying degrees of jugular venous reflux, and their influence on cerebral bloodflow studies. Two commonly encountered patterns are described. In the first group, the abnormal flow study resulted from reflux of the activity in the left internal jugular vein. In the second group, the observ...

The external jugular vein, which traverses the sternocleidomastoid muscle superficially, is known to exhibit variations in its formation and course. There are less reports on the communication of the external and internal jugular vein. During routine cadaveric dissection, we detected an abnormal communication of the external jugular vein and the internal jugular vein, in a 45 year male cadaver....

The jugular foramina were examined in 156 skulls. In 69% of cases the right was larger than the left and in 23% the left was larger, with the remainder being of equal size. An obvious dome caused by a superior jugular bulb was present bilaterally in 54%, on the right only in 30%, on the left only in 6% and was absent bilaterally in 10%. Of the 312 jugular foramina examined there was no evidence...

Superficial veins of the head and neck are utilised for central venous cannulation, oral reconstruction and parenteral nutrition in debilitated patients. Clinical and sonological examinations of these veins may provide clues toward underlying cardiac pathology. Hence, although variations in these vessels are common, a sound knowledge of such variations becomes clinically important to surgeons, ...

External jugular vein aneurysm with thrombosis presenting as neck swelling is a rare clinical entity and rarely encountered in routine clinical practice. We present a case of a 45-year-old female with external jugular vein aneurysm presenting as a painful lump in the neck. Ultrasound of the neck and CT angiography showed saccular dilation of the lower end of the external jugular vein with throm...
