        <p>Die Polycythaemia vera (PV) gehört zu den Philadelphia-(Ph-)Chromosom-negativen myeloproliferativen Erkrankungen und ist durch die Erhöhung aller drei Blutzellreihen charakterisiert. Die V617F-Mutation im JAK2-Gen in Exon 14 ist in mindestens 95% der Fälle nachweisbar und gilt als eines der beiden Hauptkriterien für die Diagnose [1, 2]. Bei einem Grossteil der V617F-negativen Patientinnen und Patienten mit einer PV kann eine JAK2-Mutation in Exon 12 nachgewiesen werden [3]. Die Betroffenen sind bei Diagnosestellung oft oligosymptomatisch [4], in ca. 20% der Fälle führen vaskuläre Komplikationen zur Diagnose [5]. Diese können in mikrovaskuläre (zum Beispiel Erythromelalgie) oder makrovaskuläre Komplikationen (tiefe Venenthrombose [TVT] / Lungenembolie, abdominelle Venenthrombosen, periphere arterielle Verschlusskrankheit [PAVK] und chronisch venöse Insuffizienz [CVI]) unterteilt werden. Bei der Pathogenese spielen der erhöhte Hämatokrit und aktivierte Thrombozyten, sowie entzündliche Prozesse eine Rolle [6]. Wir berichten von einem Patienten mit multiplen Milzinfarkten als Erstmanifestation der Erkrankung.</p>
