Dotter Interventional Institute


Establishing the Dotter Interventional Institute

Charles Dotter logo

The Dotter Interventional Institute was founded on a long tradition of excellence and achievement in cardiovascular and interventional radiology at OHSU. Dr. Charles Dotter who fathered interventional radiology had several creative and innovative coworkers and followers at OHSU.

It was at OHSU that Dr. Melvin Judkins developed the transfemoral technique for selective coronary arteriography. This technique, introduced in the mid 1960's, has since been used worldwide. Judkins also developed the "Cobra" catheter at OHSU. Dr. Vincent Hinck developed catheters for femorocerebral angiography at OHSU in the late 1960's.

Dr. Josef Rösch, a colleague of Dr. Dotter since 1967, developed the technique of transjugular intrahepatic portosystemic shunt (TIPS) in 1968. He also introduced embolic treatment of gastrointestinal bleeding and popularized transjugular liver biopsy in the early 1970's. Since the early 1980's Dr. Rösch has worked together with associates on the development of expandable metallic stents and their multiple uses. He was also a co-developer of the technique for selective fallopian tube catheterization, introduced at OHSU in the mid 1980's.

The Institute's roots can be traced the early 1980s, to discussions between Dr. Dotter and Mr. William Cook, President of Cook Group. They were concerned about the future of interventional radiology and the need for high quality interventional training for all interested radiologists and other physicians, technologists and nurses. Mr. Cook continued these discussions with Dr. Rösch in the mid and late 1980's at various interventional meetings. In April 1989, Mr. Cook took action. At the 25th anniversary of Dotter's first transluminal angioplasty and after a meeting with Dr. Peter Kohler, president of OHSU, Mr. Cook announced the donation of 2 million dollars to establish an interventional institute as a multidisciplinary center directed toward education, research and patient care in interventional treatment.

This donation was welcomed enthusiastically by OHSU, particularly by the Division of Vascular and Interventional Radiology in the Department of Diagnostic Radiology. This enthusiasm was initially tempered by disagreements among various factions within the radiology department concerning the intent of the grant. Once the disagreements were settled by separating the Institute from the Department of Diagnostic Radiology, all efforts were concentrated on formulating the structure of the Institute and preparing a formal proposal to the Oregon State Legislature.

Many advisors from inside and outside Oregon Health & Science University participated in this process. Drs. Frederick Keller, Wilfrido Castaneda, Ernest Ring, Barry Katzen and Thomas Meany were outside radiology experts consulted when forming the Institute. Furthermore, Mr. William Cook was always helpful with valuable advice. Within OHSU, Drs. Peter Kohler and Lesley Hallick were both guiding lights in developing the Institute's structure and in presenting it to the state legislature. After several hearings, the Oregon State Board of Higher Education approved the proposal and the Institute was established on April 1, 1990. Dr. Josef Rösch became its founding director.

Once this immediate goal was accomplished, the real work began. The administrative separation from the Department of Radiology, was accomplished smoothly thanks to the dedicated work of Ms. Enid Ruble. Originally, there was considerable friction between the Department of Diagnostic Radiology and the Institute. However, cooperation between both units progressively improved. Presently, with Dr. Frederick Keller as director of the Institute and Chairman of the Department of Diagnostic Radiology, both units are working closely together in teaching, research and patient care; although administratively and financially they are separate entities.
