A New York public relations executive underwent successful liver transplant surgery on Saturday night, ending an aggressive three-week public campaign to locate a suitable liver by family, friends, and co-workers.

Last night Shari Kurzrok was listed as stable in the intensive care unit of the New York University Medical Center.

On July 20, her supporters, including her employer, Ogilvy Public Relations Worldwide, launched a drive to raise awareness, holding a rally in Union Square, creating a toll-free hotline for information and potential donors, posting flyers in local hospitals, and creating a Web site titled “Help Shari Kurzrok.”

The ambitious search tactics led a spokesperson for the New York Organ Donor Network to ask dozens of area hospitals to disallow the distribution of a “Save Shari” flyer that sought a directed liver donation to Ms. Kurzrok.

According to Ogilvy, Ms. Kurzrok, 31, was admitted to the hospital the weekend of July 17 and was soon told that she needed an emergency liver transplant within a few days to survive an unknown illness.

In April, Ms. Kurzrok led a nationwide blood drive that collected more than 3.2 million pints of blood and registered more than 38,000 potential donors, prompting Ogilvy to call it “the largest ever blood donor campaign” in a press release. Ms. Kurzrok is scheduled to be married to October 15 in Long Island.

Ms. Kurzrok received her transplant through the standard procedure of the national Organ Procurement and Transplantation Network’s matching system, based on medical need.

A statement from the executive director of OPTN posted on Ms. Kurzok’s Web site said that a matching procedure based “not on personal characteristics or social status” is “fundamental to insuring public trust in the transplant system.”

On the Web site, supporters said they were glad that the drive raised awareness to the issue of organ donation. According to the United Network for Organ Sharing, there are about 89,000 people in America awaiting a life-saving organ transplant.
