vasospasm
Very lowHighly technical/medical
Definition
Meaning
A sudden, involuntary constriction or spasm of a blood vessel, reducing blood flow.
A clinical condition, often pathological, characterized by the narrowing of a blood vessel due to hypercontraction of its muscular wall. It is a key mechanism in conditions like Raynaud's phenomenon, subarachnoid hemorrhage-induced cerebral ischemia, and coronary artery spasm (Prinzmetal's angina).
Linguistics
Semantic Notes
The term almost exclusively denotes a pathological or undesirable event. It is a compound noun: 'vaso-' (vessel) + '-spasm' (involuntary contraction). Its use implies a disruption of normal vascular physiology.
Dialectal Variation

Not applicable.
Academic
Used in medical, biomedical, and physiological research papers and textbooks.
Everyday
Virtually never used. A layperson might describe the symptoms (e.g., 'my fingers went white and numb') rather than use the term.
Technical
The primary context. Used in clinical diagnoses, patient notes, surgical reports, and pharmacology (e.g., discussing calcium channel blockers to manage it).
Examples
By Part of Speech
verb
British English
- The cerebral artery may vasospasm following a haemorrhage, leading to ischaemia.
American English
- If the coronary arteries vasospasm, it can mimic a heart attack.
adjective
British English
- The vasospastic response was observed angiographically.
American English
- She was diagnosed with a vasospastic disorder affecting her digits.
Examples
By CEFR Level
- The doctor explained that cold weather can sometimes cause a painful vasospasm in small blood vessels.
- Nimodipine is routinely administered to prevent cerebral vasospasm, a dangerous complication following an aneurysmal subarachnoid haemorrhage.
- The angiogram confirmed a severe vasospasm of the left anterior descending coronary artery, necessitating immediate intervention.
Learning
Memory Aids
Mnemonic
Think: 'VASe' (like a tube or vessel) goes into a SPASM (sudden cramp). A vessel in a cramp.
Conceptual Metaphor
A HOSE PINCHING ITSELF SHUT. The blood vessel is conceptualized as a flexible tube that suddenly squeezes itself, stopping the flow.

Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод 'вазоспазм' существует и является медицинским термином, но важно не путать с более общим 'спазм сосудов'.
- Не переводить дословно как 'сосудоспазм' – это калька, в русском медицинском языке принят термин 'вазоспазм' или 'спазм сосудов'.
Common Mistakes
- Misspelling as 'vasospazm' or 'vaso-spasm'.
- Using it as a verb (e.g., 'The vessel vasospasmed'). The correct verb form is 'to go into vasospasm' or 'to develop vasospasm'.
- Confusing it with general 'muscle spasm'.

FAQ
Frequently Asked Questions
No. High blood pressure (hypertension) is a sustained increase in the pressure within arteries. Vasospasm is a temporary, localised, often severe narrowing of a specific blood vessel. While vasospasm can cause a temporary spike in pressure, they are distinct conditions.
Yes, depending on location. Cerebral vasospasm in the brain can lead to stroke, and coronary vasospasm in the heart can cause a heart attack (myocardial infarction), both of which can be fatal.
Treatment targets the cause and symptoms. It often involves medications like calcium channel blockers (e.g., nifedipine, nimodipine) to relax the vessel walls, avoiding triggers (like cold or stress), and in severe cases, intra-arterial medications or angioplasty.
No. It is a highly specialised medical term unknown to most general English speakers. You will only encounter it in medical textbooks, research, or clinical discussions.
