Incidental thrombocytosis: Should it concern the anesthesiologist?

Abstract

Preoperative thrombocytosis, often detected incidentally in surgical patients and inadvertently overlooked, has important implications for the anesthesiologists. The primary form is a chronic clonal myeloproliferative disorder usually affecting adults while the secondary type is a benign reactive disease commonly found in children. Serious perioperative hemostatic complications are reported in primary thrombocytosis and hence, a detailed preoperative evaluation and initiation of therapy to lower the platelet count (PC) is required before undertaking surgery. Patients with reactive thrombocytosis however, usually have complication-free surgeries, and if there is no prior evidence of hemostatic complications and the reactive cause can be identified, no specific perioperative intervention may be required. A thorough preanesthetic checkup and implementation of basic thrombo-prophylaxis measures in all patients with a raised PC is advocated. We present here our experience with three infants diagnosed with high preoperative PC, presumably due to reactive causes, who underwent uneventful neurosurgeries at our institution.
