Asymptomatic Isolated Calf Deep Vein Thrombosis: Does It Worsen after Varicose Vein Surgery?

In our varicose vein center, on a trial basis, among the patients with asymptomatic calf deep vein thrombosis (CDVT) we carefully selected the patients for varicose vein surgery using the requirements as follows; 1) the patients had varicose veins with incompetent saphenous veins, 2) sequential examination including DUS confirmed stability and clinical insignificance of asymptomatic CDVT, 3) the patients do not have any risk factors for DVT such as a coagulation profile disorder (antithrombin deficiency, protein C deficiency, protein S deficiency, or antiphospholipid syndrome) or malignancies, 4) surgery is possible under local anesthesia alone, and 5) the patients can understand the concept of asymptomatic CDVT and undergo the surgery on their own will and informed consent. The patients who fulfilled these conditions underwent the varicose vein surgery. Twenty-eight patients with 30 limbs with varicose veins had asymptomatic CDVT, found by preoperative duplex ultrasonography (DUS).

Prevalence of Isolated Asymptomatic Deep Vein Thrombosis in Varicose Vein Patients with Superficial Thrombophlebitis: A Single Center Experience in Japan.

Objective: Prevalence of asymptomatic deep vein thrombosis (DVT) in patients with primary varicose veins remains unclear.

Materials And Methods: Here, we conducted a retrospective study to clarify the incidence of asymptomatic DVT in patients with varicose veins, especially focusing on those with superficial thrombophlebitis (STP).

Results: Among 431 patients with primary varicose veins with saphenous vein incompetence, 20 (4.
