Ommaya reservoirs are an important surgical therapy for the chronic intrathecal administration of chemotherapy for patients with leptomeningeal carcinomatosis. Surgical accuracy is paramount in these patients with typically normal sized ventricles, and may be improved with stereotactic guidance. This paper aimed to review a large series of stereotactic Ommaya catheter placements, examining accuracy and complications. We conducted a retrospective review of 109 consecutive adult patients who underwent stereotactic Ommaya catheter placement for leptomeningeal carcinomatosis or central nervous system lymphoma at Columbia University Medical Center, USA, from 1998-2013. The rate of accurate placement in the ventricular system was 99%, with the only poor catheter position due to post-placement migration. The rate of peri-operative complications was 6.4%. Hemorrhagic complications occurred in patients with thrombocytopenia or therapeutic anti-coagulation pre-operatively or during the post-operative period. Use of stereotaxy for catheter placement of Ommaya reservoirs is safe and effective, and should be considered when placing a catheter into non-hydrocephalic ventricles.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at our hospital from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided transforaminal endoscopic lumbar discectomy (Ng-TELD) group (30 cases), while those treated with the conventional X-ray fluoroscopy method were defined as the control group (31 cases).

Background: Machine learning is pivotal for predicting Peripherally Inserted Central Catheter-related venous thrombosis (PICC-RVT) risk, facilitating early diagnosis and proactive treatment. Existing models often assess PICC-RVT risk as static and discrete outcomes, which may limit their practical application.
Objectives: This study aims to evaluate the effectiveness of seven diverse machine learning algorithms, including three deep learning and four traditional machine learning models, that incorporate time-series data to assess PICC-RVT risk.

Interventional Radiology (IR) can be a crucial player in managing placenta accrete spectrum disorder (PAS), offering minimally invasive angiographic techniques that can prevent or control hemorrhage and preserve fertility. These include prophylactic balloon occlusion of the aorta or iliac arteries, preoperative catheter placement in the iliac or uterine arteries for subsequent embolization, or pre-emptive arterial embolization preceding hysterotomy and delivery. This review provides obstetricians with an overview of IR's role in the management of PAS by describing specific endovascular techniques; existing outcomes data; and considerations for protocol development, preoperative planning, and intraoperative dynamics for when IR assists with PAS cases.

Patent ductus arteriosus (PDA) stenting is a vital intervention for neonates with ductal-dependent blood flow, offering an attractive alternative to surgical shunt placement. Despite its benefits, the procedure poses risks such as ductal spasm, branch pulmonary artery compromise, and pseudoaneurysm formation. This report presents two complex neonatal cases with distinct outcomes.
