Sylvia Booker

Sylvia Booker was a patient admitted to Seattle Grace along with her husband Kyle following an embarrassing accident. It was later revealed that before admission she had been diagnosed with a large brain aneurysm, which previous surgeons had declared inoperable.

History
Following the original diagnosis that her aneurysm was inoperable, Sylvia and her husband Kyle took a trip to Seattle so they could visit the Space Needle. Whilst having brunch, Sylvia slipped under the table to give Kyle "some special attention". A sudden twinge caused her to bite him, who without thinking grabbed a fork and plunged it into her neck. After the fork was removed by Meredith, Sylvia disclosed that her aneurysm may have been the cause and Derek was brought in for a consult. Despite being told how good a surgeon Derek was, Sylvia was reluctant for him to see her, saying that so many surgeons had given hope and taken it away and that her terminal prognosis had brought her and Kyle closer together. Derek eventually convinced Sylvia to let in him operate; saying if he was successful she could have years of decades of time with Kyle instead of just weeks.

Double Barreled Brain Bypass
As the aneurysm was too big to clip, Derek proposed a double barreled brain bypass, where arteries would be harvested from Sylvia's scalp and implanted into the brain the bypass the aneurysm. According to Derek this procedure had been performed less than a dozen times, he had performed 2, 1 was botched the other was successful. In spite of the risks, Sylvia went ahead with the surgery which ultimately proved successful.
