Cheney on the mend

Washington, D.C.

Vice President Dick Cheney returned home from a Washington hospital this week after successful surgery to repair aneurysms behind both knees. The aneurysms, which are ballooning weak spots in arteries that can burst if untreated, were the latest in a string of health problems for the 64-year-old vice president. Cheney has had four heart attacks, the first at age 37. He has undergone two angioplasty procedures to clear blocked arteries, and had quadruple bypass surgery. He also has a special pacemaker implanted in his chest to restart his heart with a jolt of electricity, should it fail again.
