[Percutaneous dynamic atherectomy with the aid of 12-F and 14-F transluminal atherectomy catheters (TEC): initial results]. / Perkutane dynamische Atherektomie mit Hilfe des 12-F- und 14-F-, transluminalen Atherektomiekatheters (TEC): erste Erfahrungen.

OBJECTIVE: The presented study reports on the first experience with the large diameter 12 F and 14 F TEC system for percutaneous dynamic atherectomy of peripheral vascular obstructions. METHODS AND PATIENTS: The 12 F and 14 F TEC-extraction catheter was used to recanalize peripheral vascular obstructions in 4 patients. The extracted material was continuously aspirated during the procedure. Three patients with intermittent claudication suffered from chronic arterial occlusion (two cases) or from stenosis of an implanted stent (one case) in the region of the superficial femoral artery. In another patient with long-term dialysis history an insufficient collier shunt was treated by atherectomy. RESULTS: Complete vascular recanalisation was achieved in all cases. Supplementary intervention was not necessary. There were no complications. CONCLUSION: Atherectomy with the large diameter 12 F and 14 F TEC allows a safe and complete recanalisation of complex peripheral vascular occlusions. Further studies must show whether the enlarged vascular intrusion is justified by more favourable results.
