Surgical treatment of varicose veins occasionally can be followed by severe limb ischemia either after surgery or sclerotherapy. We report here two cases with the clinical features and the therapeutic strategy. The first case concerned a woman operated by venous stripping. A post-operative acute ischemia occurred and was treated by femoro-femoral bypass and lumbar sympathectomy. However this procedure did not avoid persistent chronic ischemia, sciatica paralysis and equinus ankle blockage. A secondary arterial procedure associated with intensive physiotherapy and ankle arthrodesis led to a poor functional result, partly because of an irreversible algodystrophia. The second case concerned a woman treated by sclerotherapy. An injection of the drug in the retro-malleolar area was immediately followed by an acute foot ischemia. Heparin, xylocaine and sodium nitroprusside perfusion avoided a foot amputation, however osteoporosis and algodystrophia occurred. A sympathectomy was necessary two years later. These dramatic complications although unusual, may occur even with experienced physicians. Therefore a great attention is always necessary during these simple procedures. In case of acute ischemia, early diagnosis and aggressive treatment are necessary, but prevention remains more secure.

Disseminated intravascular coagulation (DIC) was recently observed intraoperatively in two patients who required correction and stabilization of scoliosis with Harrington instrumentation and spinal fusion. Despite negative bleeding history and normal preoperative coagulation parameters, each patient developed sudden massive bleeding soon after decortication of spinous processes and facet joints. Coagulation profile revealed decreased platelets, plasma coagulation factors, and fibrinogen in association with elevated fibrin split products. Cessation of all bleeding occurred within a few hours. There was rapid correction of the coagulation parameters with blood component replacement therapy, indicating that the defibrination was short-lived and had ceased by the end of surgery. A review of the literature revealed six similar cases of DIC occurring during elective orthopedic surgery, four of which involved spinal arthrodesis and/or bone grafts. We suggest that injury secondary to decortication or chipping at bone can serve as a trigger for defibrination. This type of DIC is self-limited, and ends with completion of the operation. The treatment is blood component replacement. Heparin should be avoided.
