Recurrent artery of Heubner
Encyclopedia
Heubner's artery named after the German
paediatrician Otto Heubner
is a branch from the anterior cerebral artery,, typically from the distal A1 segment or proximal A2 segment, or at the level of the optic chiasm. Its vascular territory is the anteromedial section of the caudate nucleus
and the anterioinferior section of the internal capsule
, as well as parts of the putamen
and septal nuclei
. Heubner's artery is the distal part of the medial striate artery
.
In cases of obstructed flow in the Heubner's artery, the individual may experience infarction in those subcortical areas and thus hemiparesis
. More proximal portions of the medial striate artery
may cause spastic paraparesis and sensory loss contralateral to the lesioned side. Urinary incontinence
and gait apraxia are also not uncommon findings.
Of note, occlusive damage to the medial striate artery
may also present with contralateral grip reflex issues, and symptoms of Dysexecutive Syndrome
. Contralateral gaze preference with or without transcortical motor aphasia may present in instances where the left hemisphere is affected in this type of occlusion.

Caudate nucleus
The caudate nucleus is a nucleus located within the basal ganglia of the brains of many animal species. The caudate nucleus is an important part of the brain's learning and memory system.-Anatomy:...
and the anterioinferior section of the internal capsule
Internal capsule
The internal capsule is an area of white matter in the brain that separates the caudate nucleus and the thalamus from the lenticular nucleus. The internal capsule contains both ascending and descending axons....
, as well as parts of the putamen
Putamen
The putamen is a round structure located at the base of the forebrain . The putamen and caudate nucleus together form the dorsal striatum. It is also one of the structures that comprises the basal ganglia. Through various pathways, the putamen is connected to the substantia nigra and globus pallidus...
and septal nuclei
Septal nuclei
The septal area are structures that lie below the rostrum of corpus callosum in front of lamina terminalis , composed of medium-size neurons grouped into medial, lateral, and posterior groups...
. Heubner's artery is the distal part of the medial striate artery
Medial striate artery
a branch of anterior cerebral artery, distal to anterior communicating arteries. Clinicians may refer to this artery as Huebner's artery. This artery supplies mainly the head of the caudate nucleus....

Hemiparesis
Hemiparesis is weakness on one side of the body. It is less severe than hemiplegia - the total paralysis of the arm, leg, and trunk on one side of the body. Thus, the patient can move the impaired side of his body, but with reduced muscular strength....

Urinary incontinence
Urinary incontinence is any involuntary leakage of urine. It is a common and distressing problem, which may have a profound impact on quality of life. Urinary incontinence almost always results from an underlying treatable medical condition but is under-reported to medical practitioners...

Dysexecutive syndrome
Dysexecutive syndrome consists of a group of symptoms, usually resulting from brain damage, that fall into cognitive, behavioural and emotional categories and tend to occur together. The term was introduced by Alan Baddeley to describe a common pattern of dysfunction in executive functions, such...
