“…This finding is comparable to those reported in the literature on angioplasty of the femoropopliteal artery [15][16][17]. At 1 year follow-up of this relatively small series, the cumulative success rates for PTA and PLA were 46% and 59%, respectively.…”

“…Most angioplasty series have shown that the condition of the crural vessels affects long-term prognosis [15][16][17]. Because of the relatively small number in our patient population (n = 44) no relation could be established between the status of the distal vascular bed (one, two, or three crural vessels patent before the procedure) and the patency rate after 5 year (p = 0.28).…”

“…The reasons for such a discrepancy might be manifold: the use of different laser sources, the use of catheters with an effective ablation area of only 11%, different laser protocols, and, nally, the heterogeneity of the treated lesions, consisting of stenosis and occlusions varying from 2 to 19 cm in length. 21 Femoral endathrectomy, representing the earliest method to treat occlusions, is controversially discussed, and restenosis rates seem not to differ signi cantly from PTA.…”

AIM: To demonstrate the range of applying laser angioplasty after unsuccessful recanalization of the superficial femoral artery (SFA) with conventional interventional techniques. MATERIALS AND METHODS: In a prospective trial in 94 cases with occlusion of the SFA and formerly unsuccessful conventional percutaneous transluminal angioplasty, laser angioplasty for recanalization was applied. The average occlusion length of the SFA was 17.5 cm (range 4-36 cm). The recanalization attempt was made using the crossover technique in 78 patients, in eight patients with the antegrade technique and in another eight patients using the transpopliteal technique. The primary recanalization attempt was performed with Terumo wires (curved and straight) as well as different catheters (Multipurpose/Vertebralis/Cobra). After the unsuccessful recanalization attempt the laser catheter was applied. RESULTS: The application of laser angioplasty demonstrated a successful recanalization of the SFA in 76/94 patients (80.9%). In 18 patients (19.1%) the recanalization was not possible even with percutaneous transluminal laser angioplasty (PTLA). The reason for the unsuccessful PTLA was in 10 cases due to obstructing calcified material, which was resistant to PTLA application. In four cases obstructing calcifications caused the laser catheter to be positioned in subintimal tissue, resulting in perforation of the SFA. In another four patients there was an aberrant anatomy of the SFA which resulted in a direct vessel injury after advancing the laser catheter. After a follow-up period of 12 months primary, primary-assisted and secondary patency rates were 50.0%, 65.8% and 73.7%, respectively. DISCUSSION: In primarily unsuccessful recanalization of the SFA, PTLA allows in 80% of cases a successful recanalization of the SFA. The technical success rate and the patency rate support the application of PTLA.

“…The initial success rates of Excimer laser angioplasty in superficial femoral artery occlusions varies in older literature from 50% to 80% [10]. The majority of studies quote a 70-75% patency rate at 12 months, regardless of the laser used [11]. Nonetheless, the largest series of SFA occlusions treated by Excimer laser comes from Biamino et al [12].…”

Percutaneous Peripheral Revascularisation with Excimer Laser: Equipment, Technique and Results

Laser angioplasty has been evaluated for coronary applications since the early 1980s. Early complications of dissection, perforation and thermal injury led to a loss of enthusiasm for this technique. Recent advances in catheter development, including optimally spaced laser fibres, athermic 308 nm wave-length catheters, and saline infusion techniques have produced larger laser channels, minimised thermal injury and significantly reduced vessel dissection. This improvement in equipment and technique has led to the growing use of lasers in the field of percutaneous treatment of peripheral vascular interventions. Convincing data supporting laser use in thrombus may lead to widespread use of laser in diffuse, thrombotic, long occlusions in the SFA (superficial femoral artery) and for infrapopliteal disease treatment in patients with non-healing ulcers. Little literature exists on the specific results of 308 nm Excimer laser catheter use for peripheral angioplasty. Significant research is still needed to prove the role of debulking in peripheral applications, but upcoming clinical trial data from the PELA (peripheral angioplasty vs. laser study in long SFA occlusions) and LACI (laser angioplasty in chronic ishaemia) may help to solve these questions in the near future. This article attempts to outline the technical issues of laser catheter use in percutaneous peripheral interventions, including access, sheath selection and wire techniques to cross even the most challenging obstructions in the peripheral circulation.
