DALLAS (AP) _ Isaac Hanson, the frontman of pop group Hanson, left the hospital Friday after doctors removed a blood clot that caused his right arm to painfully swell during a concert this week.

Hanson underwent surgery Thursday for venous thoracic outlet syndrome, which doctors said interrupted the blood flow from his arm back to his heart.

``It was definitely difficult to finish the rest of the show noticing that there was something serious going on,'' said Hanson, 26, whose arm remains bandaged.

Dr. Brad Grimsley, who performed the surgery, said Hanson will need to have a rib removed in the next few months to help open his vein and prevent another clot. He will remain on blood thinners in the meantime.

Hanson said he took some aspirin during the band's set at the House of Blues on Tuesday when his arm began hurting. Hanson, who also had a blood clot removed about four years ago, said he recognized he was probably going through the same thing again.

Grimsley said that while the condition isn't usually life threatening, there's a 40 percent chance of permanent disability if the condition isn't treated promptly.

``It's fortunate that he's so attune with his body,'' Grimsley said.

Hanson, best known for their 1997 hit ``MMMBop,'' plan to resume their tour Monday in Knoxville, Tenn., according to their Web site.

The three members of Hanson, who are all brothers, are from Tulsa, Okla.
