This retrospective study aimed to evaluate the technical feasibility and safety of the delayed catheter removal technique in trans-hepatic portal vein embolization (PVE) and to explore a suitable technique. This was a retrospective study. In 278 consecutive patients, the puncture tract of the trans-hepatic PVE was treated using the delayed catheter removal technique after PVE. The existence of peripheral hepatic hematoma formation was assessed using ultrasound (US). Follow-up examinations such as magnetic resonance imaging (MRI), computed tomography (CT), and/or US were performed to evaluate perihepatic hematoma formation, hemoperitoneum, and other major complications. Instant hemostasis was achieved in all patients after the procedure. PVE-associated complications were observed in 9 patients (3.24%). No perihepatic hematoma or hemoperitoneum was found in any of the patients. With the appropriate technique, the delayed catheter removal technique can be reliably utilized as a substitute for hemostasis as it is simple and free. This technique should be further evaluated and compared with other methods. This study is the first to investigate the safety and feasibility of the delayed catheter removal technique for embolizing the puncture tract of the trans-hepatic PVE.
本回顾性研究旨在评估经肝门静脉栓塞术（PVE）中延迟导管拔除技术的技术可行性和安全性，并探讨一种合适的技术。这是一项回顾性研究。在 278 例连续患者中，在 PVE 后使用延迟导管拔除技术处理经肝 PVE 的穿刺道。使用超声（US）评估外周性肝血肿形成的存在。进行磁共振成像（MRI）、计算机断层扫描（CT）和/或 US 等随访检查，以评估肝周血肿形成、血腹和其他主要并发症。所有患者在手术后即刻止血。9 例（3.24%）患者出现与 PVE 相关的并发症。所有患者均未发现肝周血肿或血腹。通过适当的技术，延迟导管拔除技术可以作为一种简单且免费的止血替代方法可靠地应用。该技术应进一步评估，并与其他方法进行比较。本研究首次探讨了延迟导管拔除技术用于栓塞经肝 PVE 穿刺道的安全性和可行性。
