The present study was carried out to provide information about outcome of the Jetstream atherectomy device for treatment of infrainguinal arteries. From February 2006 to February 2007, 172 patients with Rutherford class 1 to 5 lower limb ischemia were enrolled at 9 study sites. The endpoints were evaluation of quality of life according to the walking impairment questionnaire (WIQ) besides technical parameters. In the total study cohort, the WIQ scale maintained improved up to 12-month follow-up. Furthermore, target lesion revascularization rate was 26% (42/162), ankle-brachial index (ABI) increased from 0.59 ± 0.21 at baseline to 0.82 ± 0.27 (P < 0.05), and mean Rutherford class dropped from 3.0 ± 0.9 at baseline to 1.5 ± 1.3 at 1 year (P < .05). The results of this prospective, multicenter, clinical study demonstrate that the Jetstream atherectomy device is a potential treatment alternative for the endovascular management to improve clinical outcome in patients with peripheral arterial occlusive disease.

Article Synopsis
- An 83-year-old woman with leg pain underwent endovascular therapy (EVT) for severe stenosis in the right superficial femoral artery (SFA) using the Jetstream™ atherectomy system and a paclitaxel-coated balloon (PCB).
- Although the initial procedure showed lumen improvement, her symptoms returned 9 months later due to the development of a pseudoaneurysm and severe stenosis.
- This case highlights the risk of pseudoaneurysm as a complication of EVT with the Jetstream™ system, despite its benefits in treating calcified arterial lesions.

Although intravascular atherectomy is widely used for debulking calcified atheromas in peripheral arterial disease, it is associated with complications. Delayed rupture with pseudoaneurysm formation is rare. We report the case of a 73-year-old man who developed a 24 mm×20 mm×27 mm popliteal artery (PA) pseudoaneurysm after rotational atherectomy.

Endovascular treatment of lower-extremity peripheral disease (PAD) is associated with higher complication rates and suboptimal outcomes in women. Atherectomy has shown favourable outcomes in calcified lesions, minimising the incidence of stent placement caused by recoil or flow-limiting dissection. To date, there are no published mid-term outcomes evaluating the performance of atherectomy differentiated by sex.

Objective: We evaluated the midterm results of atherectomy-assisted angioplasty for the treatment of femoropopliteal lesions and the identification of possible subgroups of patients with superior outcomes.
Methods: We conducted a single-center, physician-initiated, nonindustry-sponsored retrospective analysis of patients with Rutherford category ranging from II to V and de novo occlusive or stenotic lesions of the superficial femoral (SFA) and/or popliteal arteries treated with atherectomy-assisted angioplasty (Jetstream rotational atherectomy + drug-eluting ballooning). In cases of subintimal recanalization or patients without an SFA stamp, with previous ipsilateral bypass surgery, systemic coagulopathy, end-stage renal disease requiring hemodialysis, life expectancy of <12 months, and intolerance to aspirin, clopidogrel, and/or heparin were excluded.
