[Percutaneous transluminal angioplasty via dorsalis pedis artery for chronic total occlusion of superficial femoral artery: a case report].

A 60-year-old woman with intermittent claudication underwent angiography, which showed total occlusion of the left superficial femoral artery and no distal flow. Computed tomography with contrast medium revealed that the occlusion extended to the popliteal artery but distal flow was maintained to the dorsalis pedis artery. Percutaneous transluminal angioplasty was attempted via the right femoral artery, but the guidewire could not be advanced. Therefore, a 4F sheath was inserted into the dorsalis pedis artery and the guidewire was passed through the occluded lesion. After pre-dilation, the guidewire was re-crossed from the right femoral artery and two stents were successfully implanted. Finally sufficient antegrade blood flow was achieved after the procedure. The trans-dorsalis pedis artery approach is a valuable option for the percutaneous transluminal angioplasty of long superficial femoral artery occlusion if the antegrade approach is impossible.

Double target method (double marker-guided extrathoracic introducer insertion).

Incidence of damage to pacemaker and implantable cardioverter defibrillator leads is an emerging problem that should be prevented. The extrathoracic venipuncture approach has been suggested as a technique for venous access to avoid the problem. This report describes the method of double marker-guided venipuncture of extrathoracic subclavian and/or axillary vein. This approach achieves definite, safe, and speedy extrathoracic venipuncture and may be especially suitable for multiple lead placement for cardiac resynchronization therapy.

Immediate and 3-month follow-up outcome after cutting balloon angioplasty for bifurcation lesions.

Balloon angioplasty of a bifurcation lesion is associated with lower rates of success and higher rates of complications than such treatment of lesions of most other morphologies. To date, the best device or procedure for bifurcation lesions has not been determined. The aim of this study was to compare the immediate and 3-month follow-up outcome of cutting balloon angioplasty (CBA) versus conventional balloon angioplasty (PTCA) for the treatment of bifurcation lesions. We treated 87 consecutive bifurcation lesions with CBA (n = 50) or PTCA (n = 37). Paired angiograms were analyzed by quantitative angiography, and angiographic follow-up was achieved for 93% of the lesions. The procedural success was 92% in the CBA group and 76% in the PTCA group (P < 0.05). Major in-hospital complications occurred in two lesions in the CBA group and six in the PTCA group (P = 0.05). The incidence of bail-out stenting in the CBA group was lower than in the conventional PTCA (8% vs 24%, P < 0.05). At the 3-month follow-up, the restenosis rate was 40% in the CBA group versus 67% in the PTCA group (P < 0.05). Clinical events during follow-up did not differ between the two groups. In conclusion, in comparison with PTCA, procedural success was greater and the restenosis rate lower with CBA. The results of this study support the use of the cutting balloon as optimal treatment for bifurcation lesions.
