WASHINGTON - The husband of U.S. Rep. Barbara Cubin, R-Wyo., has been released from the Wyoming Medical Center after spending more than two weeks there and undergoing surgery on his spleen for a blood clotting condition.

Dr. Frederick "Fritz" Cubin underwent surgery on his spleen July 9 and had at least one additional surgery while he remained hospitalized.

He had been diagnosed with thrombocytopenia, a condition in which there is a deficient number of circulating blood platelets, the cells that help blood clot, her office said in a statement at the time of the first surgery.

The congresswoman vowed to remain at her husband's side in Casper until his condition significantly improved.

She was traveling from Wyoming to Washington on Monday and could not be reached for comment, her office said. Cubin was not expected to arrive in time to make House votes on Monday evening but planned to do so the rest of the week.

The procedure Dr. Cubin had on July 9 was in an initial attempt to halt function of his spleen. It was being performed by an interventional radiologist in phases because medical experts did not feel he would survive surgery to remove the spleen, the statement by Cubin's office had said. He was expected to undergo two more procedures to completely halt his spleen's function.

In addition to the interventional procedures, Dr. Cubin underwent a multi-pronged effort to spur the natural production of blood platelets, the statement said.

He also had been hospitalized from the third week of April through much of May. He suffered from aggressive pneumonia and a critically low blood count resulting from previous chemotherapy, her office said at the time. He continued to receive outpatient care after his release.

Cubin's husband has battled an immune disorder for years. Her office said his earlier hospitalization was for complications relating to that illness.

Cubin missed all 71 votes in the House last week and more than 40 percent of votes this year.

She has missed votes because of her husband's illness before; it became an issue in previous campaigns, especially in 2001 and 2002. Her husband was very ill at the time, and Cubin defended her need to stay by his side.

Cubin has missed more votes this Congress than all but one living House member, according to a Washington Post vote database. As of Wednesday, its most recent update, Cubin had missed 284 votes, or 39.2 percent of the total 725 votes, the database showed.

Cubin's brother died in February, accounting for some of the missed votes.
