Overview
- Phlebotomy: the backbone of therapy, treatment with phlebotomy alone associated with a longer median survival compared to the use of chlorambucil or radioactive phosphorous based on a trial conducted by PV study group. Repeated phlebotomies help in cytoreduction and reduce hyper-viscosity in addition to induce a state of iron-deficiency which can help retard red-cell proliferation. Weekly sessions are conducted, by remove 500ml of blood until a target hematocrit of under 45% is obtained. This can lower rates of cardiovascular deaths and major thrombotic episodes in patients kept under this threshold based on a trial conducted in Italy. For secondary polycythemias, phlebotomy is usually reserved for the following conditions:
Indications
The mainstay of treatment for TT is medical therapy.
