Brain Stem Hemorrhage

Brainstem Hemorrhage


Presentation

  • Abstract A 38-year-old hypertensive woman presented with acute onset of cranial nerve and long tract signs referable to a lesion in the right dorsolateral pons. A hemorrhage in the suspected area was demonstrated by CT.[ncbi.nlm.nih.gov]
  • Abstract The authors present a case of a 29-year-old man who developed rapidly progressive cranial nerve palsies and a right hemiparesis secondary to a pontine hemorrhage.[ncbi.nlm.nih.gov]
  • Abstract A 76-year-old man presented with brain stem hemorrhage after burr-hole drainage for bilateral chronic subdural hematomas.[ncbi.nlm.nih.gov]
  • April 05, 2016 ; 86 (16 Supplement) April 16, 2016 First published April 8, 2015, Abstract Objective: We present a case of Superior Colliculi hemorrhage that was incidentally discover on head CT scan with the only presenting symptom of left hemi-body[neurology.org]
  • Secondary occipital lobe infarction was present in 3.5% of the patients. It is concluded that secondary brain stem hemorrhage is a common major contribution to the cause of death in stroke.[ncbi.nlm.nih.gov]
Hypothermia
  • Abstract Hypothermia increases clotting time, which is known as hypothermic coagulopathy.[ncbi.nlm.nih.gov]
Miosis
  • The fulminating malignant course is characterised by rapid onset of coma, miosis, tetraplegia and respiratory disturbances. Three quarters of all patients die within 24 hours ( 8 , 13 , 25 ).[link.springer.com]
Pupillary Abnormality
  • abnormality, and the hematoma volume were found to be associated with the 3-month poor outcome.[ncbi.nlm.nih.gov]
Suggestibility
  • Therefore, it can be suggested that the first 4 waves of BAEPs mainly originate in the ipsilateral pons, and the Vth in the contralateral higher regions.[ncbi.nlm.nih.gov]
  • Benedikt was a Viennese neurologist, best known for his controversial research suggesting that there were specific differences between normal and "criminal" brains.[dizziness-and-balance.com]
Motor Disturbances
  • OBJECTIVE: Primary brainstem hemorrhage (PBH) frequently causes severe disturbances of consciousness, papillary abnormalities, as well as respiratory and motor disturbances.[ncbi.nlm.nih.gov]

Workup

Activated Partial Thromboplastin Time Prolonged
  • However, prothrombin time and activated partial thromboplastin time prolongation associated with therapeutic hypothermia is usually mild and thus, hypothermic coagulopathy is not considered to cause clinically significant bleeding.[ncbi.nlm.nih.gov]

Treatment

  • He recovered after conservative treatment. Asymmetrical and rapid decompression, which leads to vascular disruption and/or sudden increase in cerebral blood flow, was probably responsible for the secondary brain stem hemorrhage.[ncbi.nlm.nih.gov]
  • One patient died on the second day and the other on the third day after onset despite supportive treatment. CONCLUSIONS: These cases of brain stem hemorrhage with fulminant hyperthermia should be distinguished from those with simple hyperthermia.[ncbi.nlm.nih.gov]

  • Recognizing the signs of stroke quickly is critical because the treatments are time sensitive.[massgeneral.org]
  • Patients should receive treatment as soon as possible for the best recovery. Like all strokes, brain stem strokes produce a wide spectrum of deficits and recovery.[strokeassociation.org]

Prognosis

  • CT indicates a more favorable prognosis for brain stem hemorrhage than has been previously suspected.[ncbi.nlm.nih.gov]
  • . • MRI may provide further detail and aid prognosis. • Surgery is reserved for select cases in which specific expertise is available.[medlink.com]
  • XenonCT study of regional cerebral blood flow around hematoma in patients with basal ganglia hemorrhage 160 Preliminary application of pyramidal tractography in evaluating prognosis of patients with hypertensive intracerebral hemorrhage 165 Experimental[books.google.de]
  • The prognosis has been reported to be highly dependent on the clinical severity at presentation and the presence of certain radiological markers.[ncbi.nlm.nih.gov]
  • Prognosis for Stroke Patients The prognosis for stroke patients varies dramatically between individuals. The most important factor in a patient’s brain stem stroke prognosis is time.[guidedoc.com]

Etiology

  • MRI is frequently needed to make a specific diagnosis and to separate vascular etiologies from tumor and other structural injuries. The pattern of sensory disturbance may be helpful.[dizziness-and-balance.com]

Epidemiology

  • […] by 30 days after the insult, [7] and half of the deaths occur in the first 2 days. [29] Even though the majority of deaths occurs in the first days after ICH, survivors have a long term excess mortality of 27% compared to the general population. [30] Epidemiology[en.wikipedia.org]

Prevention

  • Therefore, simultaneous and bilateral decompression with a slow rate of evacuation of massive bilateral chronic subdural hematomas is recommended to prevent serious complications such as secondary intracranial hematoma.[ncbi.nlm.nih.gov]

  • Surgical excision may prevent recurrences. Rarely, small hemorrhages may be secondary to lacunar disease (type II lacunae) ( Challa and Moody 1989 ).[medlink.com]
  • Proper care or preventing these issues can greatly lower your risk of stroke.[winchesterhospital.org]
