Summary
Transient alopecia, a temporary hair loss, can occur after endovascular coiling for posterior circulation cerebral aneurysms. This side effect, observed in the occipital scalp, typically resolves within six months.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Radiology
Background:
- Endovascular coiling is a primary treatment for complex cerebral aneurysms, especially in the posterior circulation.
- Neurosurgeons manage the clinical aspects of these procedures, despite the endovascular approach.
Observation:
- A case report details the occurrence of transient alopecia following endovascular coiling of posterior circulation aneurysms.
- The hair loss was localized to the occipital and suboccipital scalp regions.
Findings:
- The observed alopecia was temporary, resolving spontaneously over approximately six months.
- This specific post-procedural complication has not been previously documented in neurosurgical literature.
Implications:
- Highlights the potential for radiation-induced side effects, such as alopecia, during complex endovascular interventions.
- Emphasizes the need for patient counseling regarding potential risks and implementing measures to minimize radiation exposure.

01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms.
