Christine Coffey was diagnosed as having a “berry aneurysm.” The vascular surgeon assigned to Coffey was Dr. Henry Woo who reviewed Coffey’s images and advised her that an untreated aneurysm could cause sudden death.
Dr. Woo performed an Onyx brain aneurysm procedure. During the procedure, Coffey suffered brain damage that has left her with permanent hemiparesis. Hemiparesis, or unilateral paresis, is the weakness of one side of the body. Hemiparesis can be caused by different medical conditions, including stroke.
Coffey had worked at a hospital, but she is now unable to work. She also has an impaired ability to take care of her young child.
Coffey sued Dr. Woo alleging negligence in that he chose not to obtain an informed consent. The lawsuit claimed that Dr. Woo had forced the liquid Onyx embolic agent into Coffey’s small aneurysm, causing the Onyx particles to escape the aneurysm and cause a stroke. Coffey also asserted that Dr. Woo decided not to advise her of the dangers of the surgery and safer available alternatives.
