However, their clinical use has been limited by coil stiffness and time constraints for deployment. Recently developed second-generation hydrogel coils are softer and offer improved deliverability. This study aimed to evaluate their feasibility and effectiveness in transcatheter arterial embolization (TAE) for acute arterial bleeding in the body trunk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective study included 24 TAE procedures performed in 23 patients (15 men, 8 women; median age, 72\u00a0years; range, 14-88\u00a0years) between March 2019 and November 2024. Indications for TAE included iatrogenic injury (n = 7), gastrointestinal bleeding (n = 5), trauma (n = 3), aneurysm rupture (n = 3), tumor invasion (n = 3), and others (n = 3). Second-generation hydrogel coils were used in all cases, comprising a median of 78% (range, 13-100%) of the total coil length. Technical success was defined as complete occlusion of the target artery on digital subtraction angiography. Clinical success was defined as the absence of rebleeding within 24\u00a0h of embolization.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Anemia, hemorrhagic shock, and coagulopathy were present before TAE in 92% (22\/24), 21% (5\/24), and 25% (6\/24) of procedures, respectively. The mean total coil length was 40\u00a0cm (range, 4-127\u00a0cm), and the mean procedure time was 111\u00a0min (range, 58-207\u00a0min). Both technical and clinical success rates were 100% (24\/24).
