While practicing oral sex with her partner, a 44-year-old woman was left unconscious. According to her partner, her body went rigid and for two or three minutes she lost consciousness, so she was rushed to the hospital in an ambulance. When she arrived, she was already conscious and his vital signs had returned to normal.
What could happen to her? The doctors thought, at first, that it was a seizure and studied the case. She had mild asthma, but her condition was healthy and she had no major medical problems, except for a slight continuous headache. After a second examination, the doctors opted for a syncope caused by a sudden lack of blood supply to the brain due to sexual activity. They then did a CT scan, in addition to an angiography, and the images showed that she had an anterior communicating artery aneurysm of 7 millimeters. This aneurysm could be the cause of her headaches and also of a, subarachnoid hemorrhage, which is a type of stroke.
According to the authors published in BMJ Case Reports, changes in blood pressure during sex can be a factor in the occurrence of a stroke. "Activities involving sudden increases in blood pressure and sexual activity are well described as a precursor," they write. "Studies with intra-arterial monitoring during intercourse show that, during sex, blood pressure, as well as heart rate, are very fragile, during orgasm." This episode is different, since it is about an oral sex and not a penetration.
The patient recovered and there was no bleeding. At the time of hospital discharge, there were no neurological deficiencies.
After the patient was dismissed from the hospital everything went back to normal.
