The anterior communicating artery (ACoA) and its branches were examined in 22 human brains after injecting Indian ink or methylmethacrylate. The ACoA branches were divided into the small and the large. Small branches were from 1 to 5 in number (mean 2), and from 70 to 270 Μm in diameter (mean 151 Μm). Seventy-six percent of the branches originated directly(More)
OBJECTIVE Despite detailed studies of the perforating arteries, their relationships with the leptomeningeal arteries are almost unknown. These relationships can be of great significance during neurosurgical operations. METHODS The arteries of the hemispheres, which ranged in number from 17 to 36, were injected with india ink or methylmethacrylate. (More)
Interpeduncular perforating branches were found in all 69 examined posterior cerebral arteries. They varied in number from 1 to 10, with an average of 2. They arose directly from the posterior cerebral artery (47.8%), from the collateral branches of the posterior cerebral artery (30.3%), or by their own common stems (88.4%). Their extracerebral segments(More)
The distal segment of the posterior cerebral artery (PCA), which extends from the junction with the posterior communicating artery to its terminal division into the parieto-occipital and calcarine arteries, was examined in 37 brains. Three types of distal segment were distinguished. In the first type (42.9 %), the terminal division was located either in the(More)
The thalamogeniculate (TG) arteries of 30 forebrain hemispheres were examined. These vessels varied from 2 to 12 in number (mean, 5.7), and from 70 to 580 microns in caliber (mean, 345.8 microns). The average caliber of all the TG vessels per posterior cerebral artery ranged from 700 to 3400 microns (mean, 1972 microns). The TG arteries most often(More)

Thirty-three injected human brains were examined, and anastomotic vessels were found in 26 (79%) of them. Anastomoses varied in number from one to six. The mean diameter was 148 microns, and the mean length was 3.3 mm. Anastomoses were observed among the following: the branches of the single thalamoperforating vessel of the posterior cerebral artery (PCA),(More)
The authors examined the lenticulostriate (perforating) arteries in the vascular casts of 48 middle cerebral arteries (MCA), as well as in the MRI or CT scans of 32 patients with cerebral infarcts in the MCA territory. The lenticulostriate arteries ranged between two and 12 in number, and from 80 microm to 1,400 microm in size. They originated from the main(More)
The presence, position, extent, relationships to neighboring structures and size of the human pyramidal lobe were investigated in 58 human post-mortem specimens in order to determine the variability of this structure. The pyramidal lobe is found in 55.2% of cases as a single conical extension of the thyroid gland. It was present more often in male (53.1%)(More)
BACKGROUND There is limited data in the literature related to the microanatomic features of the perforating branches of the vertebral artery. METHODS The 44 vertebral arteries and their branches were injected with india ink or a radiopaque substance and examined under the stereoscopic microscope. RESULTS The perforating arteries were noted to range in(More)
