Objectives: To assess the effects of filtered blood reinfusion (FBR) on procedural outcomes of aspiration thrombectomy for pulmonary embolism (PE).
Materials And Methods: A total of 171 patients who underwent aspiration thrombectomy for intermediate-high-risk or high-risk PE between December 2018 and September 2022 were included, 84 of whom underwent thrombectomy with FBR and 87 without. Demographic data, vital signs, laboratory values, procedural details, pulmonary arterial pressures, transfusion needs, length of hospital stay, and procedure-related adverse events were recorded.
Results: The groups did not differ at baseline, other than the FBR cohort having a higher percentage of women. There was no significant difference in postprocedural vital signs or pulmonary arterial pressure. Mean fluoroscopy time and volume of contrast medium used were lower in the FBR cohort. The drop in hemoglobin level was lower in the FBR group at both 12 (FBR, -1.065; No FBR, -1.742; P > .001) and 24 hours (FBR, -1.526; No FBR, -2.380; P > .001) after procedure; accordingly, fewer patients required transfusions in the FBR cohort (FBR, 8 (9.5%); No FBR, 20 (23.0%); P = .016). There was no difference in the number or severity of adverse events or duration of intensive care unit or hospital admission.
Conclusions: FBR use during aspiration pulmonary thrombectomy reduced blood loss and transfusion requirements but had no significant effect on procedural success or adverse event rates.

Purpose: To evaluate access site adverse events following ClotTriever-mediated large-bore mechanical thrombectomy via small upper extremity deep veins (<ā6-mm).
Materials And Methods: Twenty patients, including 24 upper extremity venous access sites, underwent ClotTriever-mediated large-bore thrombectomy of the upper extremity and thoracic central veins for symptomatic deep vein obstruction unresponsive to anticoagulation. Patients without follow-up venous duplex examinations (nā=ā3) were excluded.

Hepatocellular carcinoma (HCC) stands as the predominant type of primary liver cancer, frequently accompanied by portal vein tumor thrombosis (PVTT). PVTT is a harbinger of a grim prognosis, with current treatment modalities falling short of expectations. Delving deeper into the pathophysiology of PVTT, researchers have come to recognize that PVTT and HCC may originate from different clones.

Background: While endovascular thrombectomy (EVT) has become standard of care for patients' acute ischemic stroke (AIS) due to large vessel occlusion (LVO), many patients still suffer profound neurological disability, also termed futile recanalization (FR). The BAND score, which incorporates baseline disability, age, stroke severity, and treatment time window, is derived as a simple tool for upfront prediction of FR prior to EVT. This study aims to externally validate the BAND score and to incorporate upfront imaging biomarkers into the prediction tool.

The treatment of CIRI has been extensively investigated through a multitude of clinical studies. Acupuncture has been demonstrated to be effective in treating CIRI.

Rationale: We report the efficacy of combination prednisolone and intravenous (IV) rituximab as an immunosuppressive regimen for a young male presenting with extensive venous thromboembolism including a submassive pulmonary embolism secondary to life-threatening nephrotic syndrome from very high risk anti-phospholipase-A2 receptor (PLA2R) positive membranous nephropathy. Initial treatment was with mechanical thrombectomy and anticoagulation. Thereafter, oral prednisolone was initiated to induce remission, during a period of uninterrupted anticoagulation.
