Blood flow velocities in the basal cerebral vein after head trauma: a prospective study in 82 patients.

Background And Purpose: The authors' aim was to evaluate the time course of the basal vein's (BVR) mean flow velocity (VBVR) in patients after traumatic brain injury and its relation to intracranial pressure (ICP), cerebral perfusion pressure (CPP), and the clinical outcome.

Methods: In 82 head-injured patients (13 women and 69 men, median age = 31 years, Glasgow Coma Score = 15 to 3), daily measurement of the basal cerebral vein's and the middle cerebral artery's (MCA) flow velocities and pulsatilities was performed during each patient's entire stay in the intensive care unit. No angle correction was performed.

First appearance and sense of the term "spinal column" in ancient Egypt. Historical vignette.

In contemporary anatomical nomenclature terms have often been derived from an ancient perspective of the human body. The term "spinal column" was used in ancient Egypt, symbolized by the "djet column." The authors discuss the first appearance of the term "spinal column," taking the ancient Egyptian interaction between religion and daily life into consideration, and they describe the different segments of the spinal column known to the ancient Egyptians.
