A consecutive case series was conducted evaluating proximal splenic artery embolization (SAE) with the AMPLATZER Vascular Plug 4 (AVP4) (St. Jude Medical, Inc, St. Paul, Minnesota) in eight patients with high-grade splenic trauma. Three proximal and five combined proximal and distal subselective coiling procedures were successfully performed. Mean time from device deployment to splenic artery occlusion was 4.5 minutes (range, 2.1-10.0 min; standard deviation, 2.8 min). There were no immediate complications. One patient developed a perisplenic abscess requiring percutaneous drainage and antibiotics. Results of this initial study show the suitability of the AVP4, with its ease of deployment without a guiding sheath and accurate placement, as a viable adjunct to nonoperative management of blunt splenic injury.
一项连续病例系列研究评估了 8 例高分级脾外伤患者使用 AMPLATZER 血管塞 4（AVP4）（圣犹达医疗公司，明尼苏达州圣保罗市）进行的脾动脉近段栓塞（SAE）。3 例进行了近端和 5 例近端联合远端亚选择性线圈栓塞术，均获得成功。从器械部署到脾动脉闭塞的平均时间为 4.5 分钟（范围 2.1-10.0 分钟；标准差 2.8 分钟）。无即时并发症。1 例患者发生脾周脓肿，需要经皮引流和抗生素治疗。初步研究结果显示 AVP4 具有良好的适用性，其易于部署，无需引导鞘，且定位准确，可作为非手术治疗钝性脾损伤的一种可行的辅助手段。
