Editing Vasospasm (section)

==Complications==

Vasospasm can occur in a wide variety of peripheral vascular beds under poorly understood mechanisms. Prinzmetal angina, Buerger's disease, contrast mediated selective renal vasospasm, hypercoagulability and cryoglobulinemia likely represent just a few of the known pieces of this puzzling phenomena. Ischemia in the heart due to prolonged [[coronary vasospasm]] can lead to [[angina]], [[myocardial infarction]] and even death. Vasospasm in the hands and fingers due to prolonged exposure to vibration (30 – 300&nbsp;Hz){{failed verification|date=June 2019}}{{dubious|date=June 2019}} and triggered by cold can lead to [[Hand-arm vibration syndrome]] in which feeling and manual dexterity are lost.<ref>{{cite web |url=http://www.vibrosense.eu/knowledge-bank/medical-background/hand-arm-vibration-injuries |title=Hand-Arm Vibration Syndrome (HAVS) |publisher=www.vibrosense.eu |date=2019-01-15 |access-date=2019-01-15 |archive-date=2019-01-16 |archive-url=https://web.archive.org/web/20190116150021/http://www.vibrosense.eu/knowledge-bank/medical-background/hand-arm-vibration-injuries |url-status=dead }}</ref>

===Angiography===
In angiography, vascular access through femoral and axillary arteries are preferred because they are less prone to vasospasm. Meanwhile, brachial artery is more prone to vasospasm during instrumental access.<ref>{{Cite journal|last=Lindbom|first=Åke|date=June 1957|title=Arterial spasm caused by puncture and catheterization|journal=Acta Radiologica|language=en|volume=47|issue=6|pages=449–460|doi=10.3109/00016925709170919|pmid=13444055|issn=0001-6926|doi-access=free}}</ref>

===Hypothermia Rewarming===
In a case study in 2000, following surgery for head trauma, a patient developed mild [[hypothermia]], a typical defense mechanism the brain uses to protect itself after injury. After the hypothermia rewarming period, the patient died from increased intracranial pressure and [[anisocoria]]. A sample of the cerebrospinal fluid and autopsy results indicated cerebral vasospasm.<ref>{{cite journal |last1=Jimbo|first1=H|last2=Dohi|first2=K|last3=Nakamura|first3=Y|last4=Izumiyama|first4=H|last5=Ikeda|first5=Y|last6=Matsumoto|first6=K|last7=Kushima|first7= M|last8=Takaki|first8=A|title=Fatal severe vasospasm due to rewarming following hypothermia--case report |journal=Neurologia Medico-Chirurgica |year=2000 |volume=40 |issue=9 |pages=463–6 |doi=10.2176/nmc.40.463 |pmid=11021078 |doi-access=free}}</ref>
