Isaac Hanson, the frontman for Hanson, says he hopes to be playing guitar again in a few days after having a blood clot removed from his lungs.

Hanson, 26, had surgery Thursday in Dallas. He was diagnosed with venous thoracic outlet syndrome, spokesman Ken Phillips said. Also known as Paget-Schroetter Syndrome, the potentially fatal ailment occurs when a blood clot forms in a deep arm or shoulder vein.

Dr. Bradley Grimsley, who performed the surgery, said he expected Hanson to make a full and swift recovery.

He will need to have a rib removed in the next few months to help open his vein and prevent another clot, Grimsley said.

The guitarist checked into Baylor University Medical Center after his arm became swollen and discolored during a show earlier this week.

Isaac Hanson performs with his brothers, Taylor, 24, and Zac, 2l.

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