A woman was rushed to hospital in an ambulance after her partner comment she had become unresponsive for several minutes . By the time the 44 - year - old arrived in hospital , she was amply witting and her critical signs had revert to normal .
She was ache from a restrained head ache , snitch it 6 out of 10 on the pain graduated table . Initially , her doctors conceive she had suffered a seizure , given her symptoms and the fact her cognitive role had returned to normal . Other than occasional drinking , mild asthma , and a smoking substance abuse , she had been sound and had no pregnant aesculapian job prior to her hospitalization .
Upon further review , the doctors came to believe she had suffered a reflex - mediated syncope ( a amnesia due to a sudden deficiency of blood supplying to the brain ) related to sexual activity .
" On closer history pickings , the patient reported nearing sexual climax while receive oral sex activity from her partner before losing consciousness , " the authors write inBMJ Case Reports . Her spouse report that during the episode her trunk became stiff and she lost consciousness for 2 - 3 min .
The team trust that she may have sustain an intracerebral hemorrhage , give her on-going head ache , and continue to give her a CT scan , followed by a CT angiography , which showed she had a in good order - sided 7 - millimeter anterior communicating artery aneurysm ( a jut in the artery ) . This aneurism had lead to a subarachnoid bleeding , which is a kind of accident .
The team note that changes in blood pressure during sexuality can be a broker in the onset of a accident .
" activity that ask sudden increases in blood insistency and intimate natural action is well delineate as a precipitant , " they indite in the eccentric report . " Studies with intra - arterial monitoring during coitus demonstrate that during sexual activity profligate atmospheric pressure , as well as heart rate , is very labile , with particular rise during orgasm . "
However , they say that this case is slightly unlike , in that it ask oral rather than penetrative sex .
The patient recovered follow endovascular coiling of the aneurysm ( where clotting is promote to prevent blood from entering the aneurysm ) and there was no further bleeding . Upon run , she had no neurologic shortfall .
The authors , led by Dr Jonathan Holmes of West Middlesex University Hospital , UK , reported that four calendar month after discharge the patient role continue well .
