Key result
Isolated calf deep venous thrombosis is common after lower extremity fractures, and individualized treatment is recommended, with high-risk patients receiving anticoagulation and low-risk patients undergoing observation.
Why the study?
There are no consistent international recommendations or optimal management strategies for isolated calf deep venous thrombosis, and whether to use anticoagulant therapy remains controversial.
Does anticoagulant therapy or elastic compression stockings prevent proximal thrombosis progression or pulmonary embolism in patients with isolated calf deep venous thrombosis after fractures?
Does anticoagulant therapy or elastic compression stockings prevent proximal thrombosis progression or pulmonary embolism in patients with isolated calf deep venous thrombosis after fractures?
Individualized management based on risk stratification is recommended for isolated calf deep venous thrombosis after fractures, reserving anticoagulation for high-risk patients.

May guide selective anticoagulation for post-fracture calf DVT; leaves open need for prospective trials to validate risk stratification.
Isolated calf deep venous thrombosis (ICDVT) includes thrombosis located at the far end of the popliteal vein, such as the anterior tibial vein, posterior tibial vein, fibular vein, and intramuscular vein of the soleus and gastrocnemius. This type of thrombosis has the highest incidence, accounting for approximately half of all deep vein thrombosis (DVT) cases; however, there is no consistent recommendation for ICDVT treatment across countries, and there is also no optimal management strategy. In recent years, increasing evidence has shown that ICDVT can develop into proximal DVT, even causing pulmonary embolism (PE). Therefore, some experts suggest anticoagulant therapy for this type of DVT, while others hold an opposing attitude. Therefore, the treatment strategy for this type of DVT has become a hot and difficult research topic. The purpose of this review is to summarize the characteristics of ICDVT and the effects of different treatment strategies by analyzing recent and important classical works in the literature in an attempt to provide recommendations for the treatment of this most common type of DVT in orthopaedic clinics.

Zhao et al. (2022) conducted a review in Isolated calf deep venous thrombosis (ICDVT) after fractures. Anticoagulant therapy vs. Nonanticoagulant therapy or conservative management was evaluated. Isolated calf deep venous thrombosis is common after lower extremity fractures, and individualized treatment is recommended, with high-risk patients receiving anticoagulation and low-risk patients undergoing observation.
