[Experiences with Dotter's percutaneous recanalization of chronic arterial occlusions]
Insights
Percutaneous recanalization effectively treats chronic arterial occlusions, achieving an 83% primary success rate. This minimally invasive technique offers a high patency rate for pelvic and leg artery blockages.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Therapy
Context:
- Chronic arterial occlusions in the pelvic and superficial femoral popliteal arteries affect patient mobility and quality of life.
- Traditional surgical bypass grafting carries significant risks and morbidity.
- Percutaneous recanalization offers a less invasive alternative for treating these conditions.
Purpose:
- To evaluate the efficacy and long-term outcomes of a modified Dotter percutaneous recanalization technique for chronic arterial occlusions.
- To compare the indications and outcomes of percutaneous recanalization versus traditional vascular surgery.
Summary:
- A modified Dotter technique using a double-lumen catheter was applied to 141 patients with chronic pelvic (19) and superficial femoral popliteal artery (122) occlusions.
- The procedure achieved a primary success rate of 83% (117 patients).
- Overall patency rate was 75% after the first year, with no further re-occlusions observed in dilated segments.
Impact:
- Percutaneous recanalization demonstrates a high success and patency rate for chronic arterial occlusions, offering a viable alternative to surgery.
- The technique provides a durable solution for restoring blood flow in affected limbs.
- Further analysis of indications can guide treatment decisions, optimizing patient care.
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.
