Historical aspects of the problem of surgical treatment of hemorrhagic stroke. The role of intracranial pressure in the choice of treatment tactics (review of literature)

Abstract

This article provides a literature review of the past 60 years, conducted using keywords through the PubMed Internet resource, dedicated to the methods of surgical treatment of hemorrhagic stroke. The existing published results of clinical studies do not allow us to draw unambiguous conclusions about the superiority of conservative or neurosurgical treatment in relation to the functional recovery of patients. There is a statistical significance of the advantages of surgery based on the prevention of dislocation syndrome, control of intracranial hypertension, and prevention or at least reduction of the effect of blood and its degradation products on the surrounding healthy tissue. However, large randomized controlled trials have failed to demonstrate this benefit in terms of mortality or functional outcome.There are two main areas of hemorrhagic stroke surgery – open surgery and minimally invasive methods. The practice of open surgery is associated with high trauma rates, as well as with certain risks and complications. However, craniotomy is a lifesaving measure in critical situations with signs of persistent increased intracranial pressure leading to neurological impairment. The ability to control intracranial pressure provides a chance for the choice of more optimal tactics of surgical treatment.Today, the gold standard for intracranial pressure monitoring is the installation of invasive intraventricular or intraparenchymal transducers. The method is appreciated for its accuracy, however, there are a number of disadvantages in the form of the possibility of hemorrhagic and infectious complications, as well as the high cost of the sensor itself, which limits its routine use. The inability to measure intracranial pressure before surgery causes an unreasonable expansion of indications for choosing an open method of surgery, which reduces the possibility of a better functional outcome.All of these points make it urgent to search for a non-invasive method for measuring intracranial pressure, which would contribute to the timely choice of a surgical method without the danger of worsening the clinical outcome.
