[Severe thromboembolic complications following lumbar spinal phlebography]

From a series of 400 cases of lumbar spine phlebography by selective catheterisation, 4 serious thrombo-embolic episodes were observed, including 2 cases of severe pulmonary embolism which responded favourably to medical treatment. In 3 cases, risk factors were found (prolonged immobilisation in bed past history of phlebitis). One case developed severe phlebitis of the lower limbs despite prophylactic treatment with low dose calcium heparin. In the other cases, no anticoagulant therapy was prescribed before or during the examination.
