Persistent primitive hypoglossal artery (PPHA) is a rare form of persistent embryonic carotid-basilar anastomosis. We present an unusual case of PPHA and an anterior choroidal artery (AChoA) aneurysm associated with Chiari type I malformation.

The effect of rhegmatogenous retinal detachment on retinal oxygenation
Abstract Purpose Little is known about the effects of retinal detachment on oxygen extraction from retinal vessels. The role of oxygen supply from the retinal vessels in a detached area has not previously been investigated in vivo in humans. Retinal oximetry is a non‐invasive measurement of retinal oxygen saturation.

The origin and relations of the anterior choroidal artery: an anatomical study [PDF]
There has recently been an increase in surgical interventions to the inferior temporal lobe. The aim of the present study is to examine the anatomical structure and relations of the anterior choroidal artery, which extends to this region.

Cerebral infarction due to anterior choroidal artery occlusion caused by posterior communicating artery aneurysm compression [PDF]
SummaryCerebral infarction may be associated with underlying aneurysms. Such episodes of ischemia may be caused by thromboembolism, emboli originating from a thrombosed aneurysm, or may be secondary to an occlusion of the parent vessel with a thrombus.1 ...

Inter‐eye microvascular asymmetry across stages of diabetic retinopathy: An OCT angiography study
Abstract Purpose To evaluate inter‐eye asymmetry in macular microvascular parameters across different stages of diabetic retinopathy (DR) using OCT angiography, and to explore the associations with clinical factors. Methods This cross sectional study included 442 eyes of 221 patients with diabetes mellitus type 2. Central subfield thickness (CST), area

Anterior choroidal artery territory infarction: a small vessel disease.
To investigate the cause(s) of infarction in the anterior choroidal artery territory, we studied 31 patients (18 men, 13 women) aged 19-82 (mean 58) years, with infarction in this territory documented by computed tomography.
