PHLEBOTHROMBOSIS AND PULMONARY EMBOLISM BRITIS special facilities, special instruments, and special skill. Femoral thrombectomy requires none of these things.The indications for femoral thrombectomy are: (1) when pulmonary embolism has occurred and mercifully the patient is yet in a fit condition to withstand operation, and (2) when phlebothrombosis decubiti has been diagnosed with some precision.To endeavour to stimulate surgeons, house-surgeons, and practitioners to undertake a careful clinical examination for phlebothrombosis in relevant cases is my main object in writing this paper.
