Vascular closure devices (VCDs) are effective in reducing the time to ambulation for patients undergoing cardiac catheterization procedures and in reducing the risk of vascular complications in selected patient cohorts. However, the frequency and consequence of failure of VCDs is not well defined.
From a prospective registry of consecutive patients undergoing cardiac catheterization at our center, 9823 patients who received either a collagen plug-based (Angio-Seal) or a suture-based (Perclose) VCD were selected for the study. VCD failure was defined as unsuccessful deployment or failure to achieve hemostasis. Major vascular complication was defined as any retroperitoneal hemorrhage, limb ischemia, or any surgical repair. Minor vascular complication was defined as any groin bleeding, hematoma (> or = 5 cm), pseudoaneurysm, or arteriovenous fistula. Any vascular complication was defined as either a major or minor vascular complication. Among the 9823 patients in the study, VCD failed in 268 patients (2.7%; 2.3% diagnostic versus 3.0% percutaneous coronary intervention; P=0.029). Patients with VCD failure had significantly increased risk of any (6.7% versus 1.4%; P<0.0001), major (1.9% versus 0.6%; P=0.006), or minor (6.0% versus 1.1%; P<0.0001) vascular complication compared with the group with successful deployment of VCD. The increased risk of vascular complication was unchanged in a propensity score-matched cohort.
In contemporary practice, VCD failure is rare, but when it does fail, it is associated with a significant increase in the risk of vascular complications. Patients with VCD failure should be closely monitored.
血管闭合装置(VCD)可有效减少接受心导管术患者的活动时间,并降低特定患者群体血管并发症的风险。然而,VCD 失败的频率和后果尚未得到充分定义。
从我们中心连续进行心导管术的前瞻性注册研究中,选择了 9823 例接受胶原塞基(Angio-Seal)或缝线基(Perclose)VCD 的患者进行研究。VCD 失败定义为未能成功部署或未能实现止血。主要血管并发症定义为任何腹膜后出血、肢体缺血或任何手术修复。轻微血管并发症定义为任何腹股沟出血、血肿(≥5cm)、假性动脉瘤或动静脉瘘。任何血管并发症定义为主要或次要血管并发症。在研究中的 9823 例患者中,268 例(2.7%;诊断性 2.3%,经皮冠状动脉介入治疗 3.0%;P=0.029)VCD 失败。VCD 失败患者的任何(6.7%对 1.4%;P<0.0001)、主要(1.9%对 0.6%;P=0.006)或轻微(6.0%对 1.1%;P<0.0001)血管并发症风险显著增加与 VCD 成功植入组相比。在倾向评分匹配队列中,血管并发症风险的增加保持不变。
在当代实践中,VCD 失败很少见,但当它确实失败时,与血管并发症风险的显著增加相关。VCD 失败的患者应密切监测。
