背景:尽管在急性下肢深静脉血栓形成(DVT)患者中通常使用the静脉入路进行导管溶栓(CDT)治疗,CDT通过新的访问路由,胫骨后静脉,也被使用,并已显示出良好的效果。然而,这种胫骨方法尚未在大样本中进行测试。
目的:比较应用胫静脉和骶静脉入路CDT治疗急性混合性下肢DVT的早期疗效。
方法:在这项回顾性队列研究中,选择珠海市人民医院介入医学科收治的87例急性混合性下肢深静脉血栓形成患者,采用胫静脉入路和肱静脉入路的患者作为观察组(n=55)和对照组(n=32)。分别。通过收集和比较静脉通畅等指标,探讨经胫骨静脉入路CDT的安全性和有效性,血栓清除效果,大腿和小腿围的区别,患肢的肿胀减少率,手术并发症,两组患者出院后并发症发生率。
结果:观察组术后血栓清除效果明显优于对照组(P<0.05)。观察组术后静脉通畅率为83.2±15.7%,高于对照组(62.2±38.2%)(P=0.005)。观察组下肢肿胀减轻率为74.0±33.8%,对照组为51.4±30.0%,差异有统计学意义(P=0.002)。然而,大腿肿胀减轻率差异无统计学意义(P>0.05),出血相关并发症,或两组患者术后并发症。
结论:经胫骨静脉入路的CDT是安全的,有效,可能是CDT访问的更好方法,提供优越的血栓清除,静脉通畅,术后下肢肿胀减轻。
BACKGROUND: Although the popliteal vein approach is commonly used for catheter-directed thrombolysis (CDT) treatment in patients with acute lower extremity deep vein thrombosis (DVT), CDT via a new
access route, the posterior tibial vein, is also used and has demonstrated good results. However, this tibial approach has not been tested in large samples.
OBJECTIVE: To compare the early efficacy of CDT using the tibial and popliteal vein approaches for the treatment of acute mixed lower extremity DVT.
METHODS: In this retrospective cohort study, 87 patients with acute mixed lower extremity DVT treated at the Department of Interventional Medicine of Zhuhai People\'s Hospital were enrolled; those with tibial vein
access and popliteal vein
access were included in the observation (n = 55) and control (n = 32) groups, respectively. The safety and efficacy of CDT via tibial vein
access were investigated by collecting and comparing indicators such as venous patency, thrombus removal effect, thigh and calf circumference difference, swelling reduction rate of the affected limb, surgical complications, and post-discharge complication rate of the patients in the two groups.
RESULTS: The postoperative thrombus clearance effect of the observation group was significantly better than that of the control group (P < 0.05), and the postoperative venous patency rate of the observation group was 83.2 ± 15.7%, which was higher than that of the control group (62.2 ± 38.2%) (P = 0.005). The swelling reduction rate of the lower extremity was 74.0 ± 33.8% in the observation group and 51.4 ± 30.0% in the control group, with a statistically significant difference (P = 0.002). However, there was no statistically significant difference (P > 0.05) in the rates of thigh swelling reduction, bleeding-related complications, or postoperative complications between the two groups of patients.
CONCLUSIONS: CDT via the tibial vein approach is safe, effective, and may be a better approach for CDT
access, offering superior thrombus clearance, venous patency, and lower extremity swelling reduction postoperatively.
