[Renal infarction by cannabis consumption].

Abstract

Introduction:  Renal infarction is a rare cause for an acute renal failure. At the time being, there is no sufficient correlation to the consumption of cannabis described.

Case history:  A 40-year-old male patient presented to our emergency room because of pain in the right renal bed.

Examination and findings:  The duplex ultrasound showed no ectasia, but the computed tomography confirmed a renal infraction on the right side. The further diagnostics gave no indication of a classical pathogenesis, but there was a constant consumption of cannabis documented.

Therapy and course:  We decided for a conservative treatment with analgesia, diagnostic laboratory controls and anticoagulants because of the prolonged process. The complaints decreased.

Discussion:  The correlation between thrombo-embolic events and the consumption of cannabis has to be more explored because of its recent legalization in Germany. It should be considered as a cardiovascular risk factor. Until today there are no recommendations for the anticoagulants.
