经导管主动脉瓣置换术预留两把ProGlide缝合失败后联合应用ExoSeal血管闭合器的单中心研究

Single-center study of combined application of ExoSeal vascular closure device after two

目的评价ExoSeal血管闭合器在经导管主动脉瓣置换术预留两把ProGlide缝合失败患者中的应用效果。方法回顾性分析2020年5月至2024年1月在河北医科大学第一医院心内科住院行TAVR后应用两把ProGlide缝合失败后联合应用ExoSeal血管闭合器的35例患者。总结ExoSeal血管闭合器的疗效,观察患者术后止血时间、徒手压迫时间、下肢制动时间、弹力绷带压迫时间、压迫过程出血量、术后股动脉并发症发生情况以及股动脉超声情况。通过上述指标评价ExoSeal血管闭合器在经导管主动脉瓣置换术患者中的疗效。结果(1)术后止血效果:股动脉入路的术后止血时间(6.89±2.66)min、徒手压迫时间(4.65±1.33)min、弹力绷带压迫时间(3.79±1.57)h、下肢制动时间(13.74±5.51)h、压迫过程出血量(12.74±3.61)g。(2)股动脉并发症发生情况:止血成功率为85.7%;需要止血的局部出血、血肿4例(11.4%);发生假性动脉瘤、动静脉瘘、血管撕裂伤或腹膜后出血1例(2.8%);无同侧血管功能不全或栓塞表现、穿刺处感染、入路相关神经损伤、需要手术或非手术技术修复血管发生。(3)术前及术后股动脉超声情况:股总动脉平均直径和股总动脉收缩期峰值流速差异均无统计学意义(均P>0.05)。结论ExoSeal血管闭合器在经导管主动脉瓣置换术两把ProGlide缝合失败患者中的应用安全有效。

Objective This study was to evaluate the application effect of ExoSeal vascular closure device in patients with failed ProGlide suturing af ter transcatheter aortic valve replacement.Methods Retrospective analysis of 35 patients who underwent TAVR surgery at the Heart Center of the First Hospital of Hebei Medical University f rom May 2020 to January 2024 and experienced failure in suturing with two ProGlide sutures,and subsequently underwent combined application of the ExoSeal vascular closure device.The ef f icacy of the ExoSeal vascular closure device was summarized,and the patients’postoperative hemostasis time,manual compression time,lower limb immobilization time,elastic bandage compression time,bleeding volume during compression,postoperative femoral artery complications,and femoral artery ultrasound were observed.The efficacy of the ExoSeal vascular closure device in patients undergoing transcatheter aortic valve replacement was evaluated through the above indicators.Results(1)Postoperative Hemostatic Effect:The time for postoperative hemostasis through the femoral artery was(6.89±2.66)min,the manual compression time was(4.65±1.33)min,the elastic bandage compression time was(3.79±1.57)h,the lower limb immobilization time was(13.74±5.51)h,and the amount of bleeding during compression was(12.74±3.61)g.(2)Complications of the femoral artery:The success rate of hemostasis was 85.7%;there were 4 cases of local bleeding and hematoma requiring hemostasis(11.4%);there was 1 case of pseudoaneurysm,arteriovenous fistula,vascular laceration or retroperitoneal bleeding(2.8%);there were no ipsilateral vascular insufficiency or embolic manifestations,puncture site infection,related nerve injury,surgical or non-surgical techniques for repairing blood vessels.(3)Preoperative and postoperative ultrasound of the femoral artery:There was no significant difference in the average diameter of the common femoral artery and the peak systolic flow velocity of the common femoral artery(both P>0.05).Conclusions The application of the ExoSeal vascular closure device in patients with f ailed ProGlide suturing during transcatheter aortic valve replacement is safe and effective.
