Subintimal recanalization of the femoropopliteal segment to promote healing of an ulcerated below-knee amputation stump.

摘要

PURPOSE: To describe the use of the subintimal technique to revascularize an ulcerated below-knee amputation stump. CASE REPORT: A 64-year-old man with persistent ulceration of a below-knee amputation stump underwent attempted percutaneous revascularization. Via antegrade puncture, the femoropopliteal occlusion was recanalized subintimally and eventually opened into a large medial geniculate collateral branch, improving the stump flow. The procedure was uneventful, and at 6 months, the patient was pain-free and able to mobilize with his prosthetic limb. CONCLUSION: Subintimal revascularization of a critically-ischemic below-knee amputation stump may be a useful option and should be considered in clinical situations like this.
