Overview
Indications
- 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:
- Chronic lung diseases
- Cyanotic heart diseases
- Post-renal transplant patients with hypertension and erythrocytosis, not responding to optimal doses of angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARB) [1] [2]
