Clinical, Functional, and Quality-of-Life Outcomes after Computer Assisted Vacuum Thrombectomy for Pulmonary Embolism: Interim Analysis of the STRIKE-PE Study.

Purpose: To report the first interim analysis of the STRIKE-PE study, evaluating the safety and effectiveness of computer assisted vaccum thrombectomy (CAVT) for the treatment of acute pulmonary embolism (PE).

Materials And Methods: This prospective, international, multicenter study will enroll 600 adult patients with acute PE of ≤14 days and a right ventricle (RV)-to-left ventricle (LV) ratio of ≥0.9 who receive first-line endovascular treatment with CAVT using the Indigo Aspiration System (Penumbra, Alameda, California).

Initial experience with a continuous mechanical aspiration system for thrombus removal before percutaneous coronary intervention.

Objectives: Here we investigate the safety and efficacy of a continuous mechanical aspiration system when used before percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS).

Background: Historically, trials of routine manual aspiration thrombectomy in ACS patients have reported mixed results. This may be due to the technical limitations of manual aspiration, which suffers from decreasing vacuum power as aspiration is performed.

Contrast medium-induced acute kidney injury: comparison of intravenous and intraarterial administration of iodinated contrast medium.

Purpose: To compare the incidence of contrast medium-induced acute kidney injury (AKI) after intravenous (IV) administration of iodixanol for computed tomographic (CT) angiography versus intraarterial (IA) injection of iodixanol or low osmolar contrast medium (LOCM) for digital subtraction angiography (DSA) within the same population suspected of peripheral arterial occlusive disease (PAOD).

Materials And Methods: CT angiography was performed with IV iodixanol 320 mgI/mL. After a washout period of 3-14 days, DSA was performed with IA iodixanol or LOCM.

Contrast-induced acute kidney injury (CI-AKI) following intra-arterial administration of iodinated contrast media.

Background: We report the incidence of contrast-induced acute kidney injury (CI-AKI) following administration of iodixanol or low-osmolar contrast media (LOCM) in patients for suspected peripheral arterial occlusive disease (PAOD) undergoing intra-arterial digital angiography (IA-DSA).

Methods: IA-DSA was performed according to site standard for contrast agent type and volume following computed tomography (CT) of the abdominal aortoiliac and lower extremity arteries and a washout period of at least 3 days. Serum creatinine was measured at baseline and 24 ± 4 hours after contrast administration.
