AI Article Synopsis
- Positional vertebrobasilar ischemia, or Bow hunter stroke, happens when the vertebral artery is compressed, often leading to symptoms like near syncope during head movements.
- The patient, a 61-year-old man, experienced near loss of consciousness when turning his head left, and tests showed significant issues like total occlusion of the left subclavian artery and abnormal blood flow in the vertebral arteries.
- After diagnosing these problems, an axillary-axillary bypass surgery was performed, successfully restoring proper blood flow in the left vertebral artery post-surgery.
Article Abstract
Positional vertebrobasilar ischemia, also known as Bow hunter stroke, is typically caused by mechanical compression of the vertebral artery (VA). On the other hand, subclavian steal syndrome is incidentally detected by vertigo, syncope or loss of consciousness due to the steal phenomenon. A 61-year-old man suffered from near syncope when he turned his head to the left side. Although asymmetric arm blood pressure of the right dominant was observed, arm claudication was not detected. Computed tomographic angiography and magnetic resonance imaging revealed total occlusion of the left subclavian artery, hypoplasia of the right VA and an incomplete circle of Willis. Furthermore, carotid Doppler ultrasonic echography revealed retrograde blood flow of the left VA. It means that head rotation might occur in the left VA ischemia. An axillary-axillary bypass surgery was performed and ultrasonic echography showed anterograde effective blood flow of the left VA after the procedure.

An 80-year-old man was admitted to our hospital with acute cerebellar infarction. Conventional magnetic resonance angiography and computed tomography angiography (CTA) showed occlusion of the right vertebral artery (VA). Carotid ultrasonography revealed that the right VA was narrowed at its entry point into the transverse foramen near C6.

Background: Vertebral artery (VA) stenosis can be caused by several factors, including arteriosclerosis, arterial dissection, and mechanical compression. Symptomatic vertebrobasilar insufficiency caused by VA stenosis due to mechanical compression associated with head rotation is well-known as Bow Hunter's syndrome. However, an accurate diagnosis of asymptomatic osteophyte compression-induced nonrotational VA stenosis is difficult.

Vestibular syncope is a rare condition in which vertigo may cause syncopal attacks; however, the term has been associated with confusion because it has been ascribed to completely different vestibular and neurological conditions, from dizziness to Menière disease (MD), to the neurovegetative symptoms in benign paroxysmal positional vertigo (BPPV) and central vertebrobasilar hyperfusion. A 75-year-old woman with vasodepressive vasovagal syncope, confirmed by a tilt test with trinitrine administration, was referred for an audiological and vestibular assessment showing an acute unilateral peripheral vestibular deficit on the right side. The diagnosis is peripheral acute vestibular deficits.

Article Synopsis
- Bow hunter's stroke (BHS) occurs when the vertebral artery gets compressed during head rotation, leading to temporary neurological issues and a risk of stroke.
- A case study of a 25-year-old woman who developed multiple cerebral infarctions after sleeping with her head rotated showed that her vertebral artery was affected by this position.
- The treatment involved a surgical procedure to stabilize the cervical vertebrae, which successfully prevented further incidents, highlighting the importance of considering sleep position in similar cases.

Background: Vertebral artery compression syndrome is a rare condition defined as the clinical presentation of dizziness, vertigo, ataxia, dysarthria, dysphagia, progressive or acute paralysis, hemisensory loss, and cervical myelopathy secondary to compression of the medulla and upper spinal cord by the vertebral artery.
Case Description: Here we describe a 57-year-old Mexican-American male with bulbar symptoms, positional vertigo, and diplopia. The patient's symptoms were managed through microsurgical decompression of the medulla utilizing a far lateral transcondylar approach.
