Background: Lymphatic leaks are associated with significant mortality and morbidity. Intranodal lymphangiography (ILAG) involves the direct injection of ethiodised lipid into the hilum of lymph nodes. It is diagnostic procedure that can have therapeutic effects secondary to a local sclerosant effect.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.

The anatomical characteristics of middle cerebral artery aneurysms make endovascular treatment difficult. This study evaluated the efficacy and safety of endovascular treatment of unruptured middle cerebral artery aneurysm in preventing rupture. A retrospective review of patients who underwent coil embolization for unruptured middle cerebral artery aneurysm between 2006 and 2022 at Nagoya University Hospital with at least 12 months followed up was conducted.

Selecting an appropriate microcatheter tip shape for paraclinoid aneurysms is difficult. Therefore, we devised an original simple and uniform three-dimensional (3D) spiral-shaping method of microcatheter and validated the characteristics and usefulness of this method for coil embolization of paraclinoid aneurysms using patient-specific silicone models. These silicone models were produced based on clinical data from four patients with four paraclinoid aneurysms that underwent endovascular treatment using the 3D spiral-shaping method.

Purpose: To investigate the safety and efficacy of endovascular embolization combined with external drainage for poor-grade ruptured cerebral aneurysms and risk factors.
Materials And Methods: Forty-six patients with poor-grade ruptured cerebral aneurysms treated with endovascular embolization combined with decompressive craniectomy and drainage were retrospectively enrolled.
Results: Coil embolization alone was performed in 29 (63.
