Abstract:
Hemorrhagic
accidents under vitamin K antagonists (VKA) are the leading cause of iatrogenic
hospitalizations Hemorrhagic stroke associated with vitamin K antagonists in emergencies.
The
clinical relevance of vitamin K antagonists (VKA) has been demonstrated in many
pathological situations thromboembolic their prescription is increasing. The
occurrence of bleeding is the most feared complication of VKA and prevention
remains a key concern in the des patients monitoring under VKA. The purpose of
this study is to highlight the epidemiological, clinical and evolutive characteristics
of patients with hemorrhagic stroke in VKA and put the focus on support. We
conducted a retrospective study during the period of January 2018-December 2019
of 9 patients, performed service emergency of the military hospital Avicenna.
The
average age of our patients is 54.5 with a sex ratio of 1.25. We note in our
series multi- calibrated field VKA patients with more history involved.
Valve replacement was the main indication
identified. The majority of our patients did not have a good biological
monitoring based on international normalized ratio (INR). Externalized bleeding
was the most common. Conduct was different depending on the case based on the
judgment of VKA, administration saw K, transfusion of red blood cells and fresh
frozen plasma and surgical homeostasis. 1 patient admitted died. The index
Landefeld has proved useful, it allows to classify patients according to the
predictive risk of bleeding (high medium or low), which was consistent with the
results of our study. Its importance is all the more it is easy to measure
simply based on data clinques applicable by the physician -patient and to
define patients requiring increased surveillance. Polypharmacy, advanced age
and associated defects were identified as risk factor for bleeding under VKA.
Preventing the occurrence of these accidents is based on the assumption, hence
the importance of information and education of stakeholders in this iatrogenic
potentially lethal complication.
