Karpaltunnelsyndrom auf Grund einer Arteria mediana – Thrombose – Vier Fallbeispiele und Literaturzusammenfassung

Zusammenfassung

Die Ätiologie des Karpaltunnelsyndroms ist in den meisten Fällen unklar. In unserem Patientengut haben wir vier Fälle gefunden, bei denen eine thrombosierte Arteria mediana Ursache einer akuten Karpaltunnelsymptomatik war. Ziel dieser Arbeit ist der Vergleich unserer Fallbeispiele mit denen aus der vorhandenen Literatur sowie das Aufzeigen allfälliger Thromboseursachen und Risikofaktoren. Schlussfolgernd muss festgestellt werden, dass eine Arteria mediana-Thrombose sicherlich sehr selten ist, aber dass bei akut einsetzenden Karpaltunnelsymptomen, begleitet von über das normale Maß hinausgehenden Schmerzen, an diese Ursache gedacht werden muss. Präoperativ kann die Thrombose mittels Ultraschall festgestellt werden.

Abstract

The aetiology of the carpal tunnel syndrome is unknown in most cases. Among our patients we found four with acute thrombosis occurring in a persistent median artery which led to acute carpal tunnel symptoms. The purpose of this study was to compare our cases with those from the literature and to show possible causes for the thrombosis. In conclusion, thrombosis of a persistent median artery as a cause of acute carpal tunnel syndrome is certainly very rare. Sudden onset of pain, local tenderness at the palm and decreased sensation in the median nerve distribution may provide clues for the diagnosis. Prior to surgery ultrasound can be performed to confirm the diagnosis.
