Hyperkalemia in an intravenous catheter direct thrombolysis patient: a case report

Heparin may cause hyperkalemia by blocking aldosterone biosynthesis in the adrenal gland. A 68-year-old female patient was diagnosed as deep vein thrombosis and received intravenous catheter direct thrombolysis. The patient suffered hyperkalemia without systemic infection, cardiac or renal failure, adrenal insufficiency, or sudden anemia. The plasma potassium level normalized after heparin changed to fraxiparine. Here, we have reviewed the literature and discussed risk of heparin-induced hyperklamia.
