Mechanical Thrombectomy Using Kissing Y-Solitaire as a Rescue Treatment for Refractory Acute Popliteal and Infrapopliteal Occlusion in Elderly Patients.

Six patients were included to retrospectively review the preliminary efficacy and safety of mechanical thrombectomy using kissing Y-Solitaire as a rescue treatment. This technique was performed following failed single Solitaire thrombectomy in 5 patients (5/6), and the remaining patient (1/6) underwent unsuccessful AngioJet thrombectomy (Boston Scientific, Marlborough, Massachusetts). The ranges of the target vessel clot length and diameter were 4.9-6.9 mm and 27-38 mm, respectively. Technical success was achieved in all patients (6/6). They (6/6) had notable acute limb ischemia (ALI) symptom relief after 1 or 2 passes of retrieval, and clinical success was achieved in all patients (6/6). No complications were observed other than reversible vasospasm in 1 patient (1/6). Amputation or death did not occur. Mechanical revascularization with the use of kissing Y-Solitaire seems to be a potentially rapid, safe, and effective modality for selected patients with refractory short-segment occlusion of ALI secondary to popliteal and infrapopliteal arteries.
