Polycythaemia vera is a chronic condition that results in erythrocytosis and puts customers prone to peri-operative problems including thrombotic events and paradoxical haemorrhage. Little research exists in the perfect peri-operative management of uncontrolled polycythaemia vera if the proposed treatment carries a top risk of haemorrhage. Our patient presented with a pre-operative haemoglobin of 197 g.l-1 (haematocrit 65%) and had not been phlebotomised pre-operatively. Intra-operatively he destroyed 2700 ml of bloodstream, reducing his haematocrit to 48per cent, after which experienced deadly thrombotic complications postoperatively. The individual did not get any bloodstream product transfusions during his peri-operative program. We examine the readily available proof to guide the peri-operative management of customers with polycythaemia vera. The inherent dangers of thrombosis and haemorrhage related to polycythaemia vera must be weighed contrary to the certain medical and transfusion-related risks. Phlebotomy to obtain a pre-operative haematocrit under 45% is recommended and intra-operative phlebotomy reveals vow for reducing blood loss during hepatectomies. Management of postoperative erythrocytosis could be an important and underappreciated element of reducing the peri-operative risk of thrombosis in patients with polycythaemia vera. © 2019 Association of Anaesthetists.The decision to administer thrombolysis in submassive pulmonary embolism is done centered on risk stratificat
