Insights
Catheter-directed thrombolysis (CDT) effectively treats acute lower-extremity deep venous thrombosis (LEDVT). The anterior tibial vein approach (ATVA) offers a safer alternative to the popliteal vein approach (PVA), with fewer complications.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Thrombosis Management
Background:
- Acute lower-extremity deep venous thrombosis (LEDVT) poses significant clinical challenges.
- Catheter-directed thrombolysis (CDT) is a key treatment modality for extensive LEDVT.
- Optimizing CDT approaches is crucial for improving patient outcomes.
Purpose of the Study:
- To compare the clinical efficacy and safety of CDT using the anterior tibial vein approach (ATVA) versus the popliteal vein approach (PVA).
- To evaluate complication rates and long-term outcomes, including post-thrombotic syndrome (PTS) and venous insufficiency.
Main Methods:
- A study involving 63 patients with unilateral acute extensive LEDVT.
- Patients were divided into two groups: CDT via PVA (36 patients) and CDT via ATVA (27 patients).
- Key metrics included thrombus score, limb circumference, complication rates, thrombolytic agent administration, and 1-year follow-up for PTS and venous insufficiency.
Main Results:
- Both ATVA and PVA groups showed significant thrombus reduction (P < 0.001).
- The ATVA group exhibited a lower limb circumference difference below the knee (P = 0.029) and fewer complications, particularly sheath bleeding (P = 0.025).
- No significant differences were observed in detumescence, thrombolytic rates, or thrombolytic times between groups. Long-term PTS and venous insufficiency rates were comparable.
Conclusions:
- CDT is an effective and safe treatment for acute LEDVT.
- The ATVA is a feasible and effective approach for CDT, demonstrating a lower incidence of complications compared to the PVA.
- ATVA may be a preferred route for CDT in select LEDVT cases.
Background:
To compare the clinical efficacy and safety of catheter-directed thrombolysis (CDT) using the anterior tibial vein approach (ATVA) and popliteal vein approach (PVA) for acute lower-extremity deep venous thrombosis (LEDVT).
Methods:
From March 2014 to October 2015, 63 patients with unilateral acute extensive LEDVT were enrolled in this study: 36 patients received CDT via the PVA group, and 27 patients received CDT via the ATVA group. Limb circumference, thrombus score, complications, thrombolytic time, and the amount of thrombolytic agents administered were recorded. Postthrombotic syndrome (PTS) and venous insufficiency were assessed at 1 year after treatment.
Results:
Thrombus scores were significantly decreased in both groups after CDT therapy (each P < 0.001). There was no significant difference in the detumescence and thrombolytic rates, thrombolytic times and administered amounts of thrombolytic agents between the 2 groups (each P > 0.050). The limb circumference difference below the knee in the ATVA group was lower than that in the PVA group (P = 0.029), and the ATVA resulted in fewer complications, especially sheath bleeding (P = 0.025). At the 1-year follow-up, popliteal venous insufficiency was present in 36.11% of the PVA group and 25.93% of the ATVA group (P = 0.390). In addition, PTS was observed in 13.89% of the PVA group compared with 7.41% of the ATVA group (P = 0.268).
Conclusions:
CDT is an effective and safe method for treating acute LEDVT. The ATVA is an effective and feasible approach for CDT with a lower incidence of complications than the PVA.

What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...
