Objective: To evaluate safety and efficacy of endovascular treatment of middle cerebral artery dissecting aneurysms (MCADAs).
Methods: Between July 2009 and April 2016, 14 patients with MCADAs received endovascular treatment. MCADAs were identified by their unique radiographic features on cerebral angiography. Baseline characteristics, angiographic features, and angiographic and clinical outcomes were analyzed retrospectively.
Results: All 14 MCADAs (including 6 ruptured and 8 unruptured) were successfully treated with the endovascular approach. Stent-assisted coiling was used in 12 cases, coil alone in 1 case, and parent vessel occlusion in 1 case. Angiographic follow-up data were available for all patients at 6 months after treatment. Of 14 MCADAs, 10 were completely occluded, and 4 were improved (near occlusion). All parent arteries and covered perforators remained patent in the non-parent vessel occlusion group. No ischemic strokes or other complications were observed at 1-year clinical follow-up.
Conclusions: Our data suggest that endovascular treatment of MCADAs appears to be safe and effective. The choice of treatment method needs to be individualized. Larger studies are required to evaluate these promising results.

Introduction: Patients with peripheral artery disease (PAD) can experience intermittent claudication, which limits walking capacity and the ability to undertake daily activities. While exercise therapy is an established way to improve walking capacity in people with PAD, it is not feasible in all patients. Neuromuscular electrical stimulation (NMES) provides a way to passively induce repeated muscle contractions and has been widely used as a therapy for chronic conditions that limit functional capacity.

Endovascular intervention is a safe, effective treatment modality in the management of diverse pulmonary vascular pathologies, including acute or chronic thromboembolic disease, pulmonary arteriovenous malformations (pAVMs), pulmonary artery or bronchial artery hemorrhage, and foreign body retrieval. This article reviews indications, contraindications, techniques, and outcomes in endovascular management of common pulmonary vascular pathologies, with the goal of improving operator familiarity and facility with these procedures.

Objectives: This study assessed the association between chronic obstructive pulmonary disease (COPD) severity and postoperative mortality among patients undergoing thoracic endovascular aortic repair (TEVAR) and complex endovascular aortic repair (CEVAR).
Methods: A retrospective review of the Vascular Quality Initiative database identified elective TEVAR and CEVAR cases from 2013-2022 with endograft proximal landing zone ≥2 for thoracic or complex abdominal aortic disease. Symptomatic disease, ruptures, and urgent/emergent surgeries were excluded.

Objective: High D-dimer levels may increase the likelihood of unfavorable clinical outcomes in patients with acute ischemic stroke. However, the impacts of serum D-dimer levels on outcomes of reperfusion treatment in patients with acute ischemic stroke have not been evaluated. This study aims to assess a possible relationship between serum D-dimer and functional outcomes in stroke patients with endovascular treatment (EVT).
