Update on Senator Johnson

According to Johnson's attending physician:

Subsequent to his admission to George Washington University Hospital, Senator Tim Johnson was found to have had intracerebral bleed, caused by Congenital Arteriovenous Malformation.  He underwent sucessful surgery to evacuate the blood and stablize the malformation.

Senator Johnson's wife, Barbara Johnson, released a statement saying:

The Johnson family is encouraged and optimistic.  We are grateful for the prayers and good wishes of friends, supporters and South Dakotans.  We are especially grateful for the work of the doctors and all medical personnel in GWU Hospital.

The medical specialist on CNN describes "Congenital Arteriovenous Malformation" as, "a cluster of blood vessels that grow too close together and can sometimes bleed. It's often congenital, meaning someone has it their entire lives...hypertension or some other factor causes can cause it to bleed."

Senator Johnson remains in critical condition, but that was described as standard after a surgery like this.  A press conference will be held this morning to give further updates on the Senator's condition.

Update:  From the AP:

The senator is recovering without complication," the physician, Adm. John Eisold, said. "It is premature to determine whether further surgery will be required or to assess any long-term prognosis.
