Summary
A patient with trigeminal neuralgia (TN) found relief after microvascular decompression (MVD). This surgery addressed a primitive trigeminal artery (PTA) compressing the trigeminal nerve, leading to successful pain reduction.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Trigeminal neuralgia (TN) is a debilitating neuropathic pain condition.
- Vascular compression of the trigeminal nerve is a common etiology for TN.
- Primitive trigeminal artery (PTA) is a rare congenital vascular anomaly.
Observation:
- A 66-year-old male presented with classic trigeminal neuralgia symptoms.
- Magnetic resonance angiography (MRA) identified a PTA in close proximity to the trigeminal nerve.
- Intraoperative findings confirmed the PTA's contact with the trigeminal nerve.
Findings:
- Microvascular decompression (MVD) was successfully performed to alleviate the neurovascular conflict.
- Post-operative assessment showed complete resolution of the patient's trigeminal neuralgia pain.
- No surgical complications were reported following the MVD procedure.
Implications:
- This case highlights the importance of identifying rare vascular anomalies like PTA in TN.
- MVD is an effective surgical treatment for TN caused by PTA compression.
- Accurate pre-operative imaging (MRA) is crucial for successful surgical planning and outcomes in TN.

01:26Transient Ischemic Attack l: Introduction
4
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. One...

01:10The Arch of Aorta
2.2K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

5.8K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:29Increased Intracranial Pressure ll: Pathophysiology
5
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins...

01:27Angina II: Classification

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...
