title: [Experiences with Dotter's percutaneous recanalization of chronic arterial occlusions].
abstract: Since 1971 141 patients (mean age 66 years, range 46-85 years) with chronic occlusions of the pelvic (19) and superficial femoral popliteal arteries (122) have been treated by the percutaneous recanalization technique first described by Dotter and Judkins in 1964. Since 1974 we have employed a modification of the original Dotter technique. The occluding material is removed with a double-lumen distensible catheter introduced over a guide wire. Primary success was achieved in 117 (83%) patients. Re-occlusions occurred in 18 patients after 6 months and in 5 patients in the second half of the first year, giving an overall patency rate of 75%. Up to now no further re-occlusions of dilated arterial segments have been observed. Indications for this treatment as compared with vascular surgery are discussed.
