الخثار الوريدي العميق البعيد المعزول: البروتوكول بعد امتداد الخثرة على تصوير الأمواج فوق الصوتية المراقبي

Isolated distal DVT ("calf DVT") is VTE below the popliteal vein.

In contrast, patients with a low risk of thrombus extension (ie, they do not meet the criteria in Table 1) should be monitored for extension with serial ultrasonography once weekly for 2 weeks, as well as for worsening of symptoms.

For patients with evidence of proximal extension, there is a strong recommendation to anticoagulate for 3 months.

For extension confined to distal veins or for new distal thrombosis, the recommendation is to anticoagulate for 3 months, but this is a weak recommendation with a very low certainty of evidence.
