Medical History

PatNum: 67


Birthdate: 11/1/1957

Age: 58

Cause of death: Likely complications due to frontal lobe brain tumor, diabetes, and hypertension.


Patient was already signed up with the Cryonics Institute.   He had a terminal brain tumor, but passed away unexpectedly while still fairly asymptomatic.  He was living alone at the time, and the body was not found for a number of days. The coroner refrigerated the body, but did not release it for an additional two days while other next of kin were sought.


A discussion with his significant other regarding cryonics revealed that he would have wanted preservation even if there was very low chance of recovering any memories.  We took this case in order to respect his last wishes rather than because the prognosis was reasonable.  The funeral director described the body as being in a state of decomposition.  Because of this and because the patient was obese, it was not possible to ship the entire body to Oregon.  We depended on a local autopsy technician to remove the brain.


Funds had been set aside, but the sudden death caused the funds to become tied up in probate for a few months.  We were able to begin diffusion of cryoprotectant while waiting for cryopreservation funding to become available.
