Deep venous thrombosis is 50 times less frequent in upper than in lower limbs. Data remain poor in the literature. Forty consecutive patients (24 males, 16 females, mean age: 54.5 years) were retrospectively analysed from 161 subjects who underwent venous explorations of the upper extremity for a 3.5 year period in the same center. Diagnosis of
thrombosis was made by duplex ultrasonography (n =37) or phlebography (n =3). Main clinical manifestations were
edema (n =36) and
pain (n =29). Location of
thrombosis was humeral (n =1), axillary (n =2), or sub-clavian (n =37, 2 bilateral). The majority of
thrombosis (n =29) were secondary to
cancer and venous
catheter (n =19, 15 implanted ports), to central
catheter alone (n =3) or
cancer alone (n =7). The 11 others were associated with
thoracic outlet syndrome (n =6) or apparent primary
thrombosis (n =5).
Thrombophilia was identified in 6 out of these 11. During follow up [mean of 9 months (0,5-36)], two patients developed
pulmonary embolism, 14 a post-thrombotic syndrome and 16 patients died. Initial
therapy included
heparin (n =36) or fibrinolysis (n =4). Upper extremity
deep venous thrombosis are mostly associated with
cancers and venous
catheters.
Thrombophilia is frequent in the other cases.
Heparin followed by oral anticoagulation is the optimal
therapy whose duration depends upon underlying condition. Fibrinolysis has not been useful for preventing post-thrombotic syndrome in our study.
