“…Her face showed severe congestion with severe bleeding in the conjunctiva, tongue and scalp, since she was found death in a head-down tile and her internal jugular veins were incomplete [1]. Since then we have studied and reported about morphological and distributional variations in blood vessels in the neck and Willis circle [2][3][4][5][6]. In this study we show morphological and distributional variation of the blood vessel in the cranial-cervical legion.…”

The blood vessels in the head and neck have several main roots for supplying blood to the brain and returning of blood to the heart. It was well known that each artery and vein in the head and neck has its variation. The variation of the vessels sometimes gives rise to un-expectable findings, which are not described in the textbook. In this study we will show the morphological variations observed at routine autopsy cases and some forensic pathological findings caused by those variations.

“…1,2 These valves typically are located 0.5to-2 cm above the union of either the subclavian vein or the innominate vein depending on laterality. 3 On the second attempt with ultrasound guidance, we again met resistance when we tried to advance the catheter off of the dilator assembly. Although the wire continued to move freely and elicit narrow-complex ectopy, we removed the dilator and catheter assembly.…”

“…It inhibits retrograde flow from the right atrium to the brain. [ 1 ] This valve prevents a sudden increase in the jugular venous pressure during positive pressure ventilation or conditions with raised abdominal pressure (e.g., ascites). Thereby it prevents cerebral congestion by avoiding excessive backward flow to the brain.…”
