Warfarin Toksisitesine Bağlı Bilateral Oksipital Hematom ve Kortikal Körlük

Year 2013, Volume: 4 Issue: 2, 73 - 75, 01.04.2013

Abstract

Kanama, antikoagülan ajanlarının sık gözlenen bir komplikasyonudur.
Warfarinin artan sayıda hasta tarafından uzun süreli kullanımı,
çeşitli kanama komplikasyonlarını beraberinde getirir. İntraserebral
kanamalar da bu komplikasyonlardan biridir. Seksensekiz yaşında
erkek hasta sabah saatlerinde başlayan ani bilateral görme kaybı
şikayeti ile acil servisimize başvurdu. Laboratuar incelemelerinde
INR değeri; 6.24 ölçüldü. Üç yıl önce inme geçirdiği ve sonrasında
oral warfarin sodyum (5 mg/gün) aldığı öğrenildi. Beyin tomografisinde
bilateral oksipital bölgede lokalize serebral hemoraji ile
uyumlu görünüm izlendi. Kanama alanında regresyon gözlenen
hasta, yatışının 20. gününde nöroloji kliniğimizden taburcu edildi.
Sonuç olarak bu ilaçların kullanımlarının artacağı açık olup tedavi
gelişiminde ise anlamlı ilerleme olmaması bu tür mortalitesi ve
morbiditesi yüksek intrakranial kanamaların ileride daha sık görülebileceğini
düşündürmektedir..

Cortical Blindness and Bilateral Occipital Haemorrhage due to Warfarin Overdose

Year 2013, Volume: 4 Issue: 2, 73 - 75, 01.04.2013

Abstract

Bleeding is a common complication of anticoagulant agents. Rising numbers of patients requiring warfarin, as well as increasing long term use, causes some haemorraghic complications. Intracerebral haemorrhage is one of these complications. An 88 year old patient was admitted to our emergency department with acute loss of sodium (5 mg/day) visual acuity. INR was 6.24 in laboratary findings. The patient had a stroke three years previously and used warfarin sodium (5 mg/day) for anticoagulation. Bilateral occipital haemorrhage was diagnosed in cerebral tomography. The patient was discharged from neurological care 20 days after admission. We suggest that the incidence of cerebral haemorrhage due to warfarin overdose will increase due to growing rates of anticoagulant treatment in the population
