Renal vein aneurysms (RVAs) are considered rare clinical entities. RVAs can be secondary to thrombosis, venous hypertension, or renal arteriovenous fistula (RAVF). RVAs secondary to RAVF are rare. Patients with RVA may present with hypertension, abdominal pain, hematuria, or may even be asymptomatic. However, there may be life-threatening emergencies including aneurysm rupture, thrombosis, and pulmonary embolism. The treatment of RVAs includes reconstruction of the renal vein, nephrectomy, and endovascular treatment. In this technical note, we report the endovascular treatment of a giant RVA that developed secondary to an acquired RAVF by the placement of multiple vascular plugs. Endovascular occlusion of the RAVF with vascular plugs is effective to prevent a life-threatening rupture of RVA. Clinical follow-up is crucial to detect leakage or migration of the vascular plugs.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

Objective: This study was to explore the factors associated with prolonged hospital length of stay (LOS) in patients with intracranial aneurysms (IAs) undergoing endovascular interventional embolization and construct prediction model machine learning algorithms.
Methods: Employing a retrospective cohort study design, this study collected patients with ruptured IA who received endovascular treatment at Jingzhou First People's Hospital during the inclusion period from September 2022 to December 2023. The entire dataset was randomly split into training and testing dataset with a 7:3 ratio.

Unlabelled: Carotid Blowout Syndrome (CBS) is a rare and life-threatening condition that necessitates prompt intervention to prevent fatal hemorrhage. This study compares the outcomes of two primary endovascular approaches: reconstructive interventions, which aim to preserve carotid artery function using stents or balloon angioplasty, and deconstructive interventions, which involve vessel occlusion to halt bleeding. A systematic review and meta-analysis were performed by searching multiple databases for relevant studies published from January 2000 to August 2023.

Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Rationale: The Chemical Optimization of Cerebral Embolectomy (CHOICE) trial suggested that the administration of intra-arterial alteplase after successful endovascular thrombectomy (EVT) may improve neurological outcomes in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO) in the anterior circulation. However, the use of adjunctive intra-arterial alteplase following successful EVT in acute posterior circulation stroke remains unexplored.
Aims: This study aims to investigate the efficacy and safety of intra-arterial alteplase after successful EVT for AIS-LVO in the posterior circulation.
