那是早上五点半。.m. when Claudia Sims awoke to the sound of wheezing. "Odd," she thought; her husband, Gary Seifer, hadn't had an asthma flare-up for years. 拼命地听, she realized that he was gasping as he struggled to pull himself up from a fall next to the bed. 奔向她丈夫的身边, she found him partially paralyzed, his mouth drooping and lopsided – a hallmark of a stroke.

Sims拨打了911.

At 75, Seifer was healthier than many of his peers, still taking on small construction projects and working out several times a week on an exercise bike. But he had a history of atrial fibrillation (A-fib), an irregular heart rhythm that raises the risk of blood clots and strokes. Years earlier, he had undergone two surgeries to correct his A-fib and reduce his stroke risk.

当救护车到达时, Seifer was taken to nearby Sonoma Valley Hospital, 是加州大学旧金山分校健康中心的附属机构, where he underwent a CT扫描 to confirm the stroke. The Sonoma team transferred him to UCSF, which has a 综合冲程中心, the highest certification awarded to hospitals that can treat the most complex cases. "We deliver outstanding innovative care, from the emergency department to the in-hospital setting, 提供急症治疗, 促进中风预防, and enhance recovery and rehabilitation,” the center's medical director, Dr. 安东尼金, who would oversee Seifer's care.

When Seifer arrived at UCSF Helen Diller Medical Center at Parnassus Heights, a plan for his care was already in place.

By then, it was too late to use clot-dissolving drugs, explained Dr. 史蒂文Hetts, co-chief of neuro-endovascular surgery. "Too many hours had elapsed between the time when he was last seen well. Generally, you have to get those medications within three to four-and-a-half hours of symptom onset."

而不是, 塞弗接受了栓子切除术, 其中导管(细), flexible tube) was threaded from an artery in his thigh to the clot in his brain. The clot was then removed using a device inserted into the catheter. "This was a life-threatening stroke or one that could have left Seifer with serious disabilities,” Dr. Luis Savastano, Hetts' co-chief of neuro-endovascular surgery, who performed the procedure. "Early recognition and transfer to our center changed his life."
