[Endoscopic biopsy of a frontal lobe tumor infiltrating the lateral ventricle using intraoperative navigation]. / Endoskopicheskaya biopsiya opukholi lobnoi doli golovnogo mozga, prorastayushchei v bokovoi zheludochek, s ispol'zovaniem intraoperatsionnoi navigatsii.

The authors describe the clinical observation of a patient with a paraventricular tumor of the left frontal lobe and demonstrate the effectiveness of endoscopic biopsy of a volumetric mass of such localization through the lateral ventricle using intraoperative navigation. The disease manifested with convulsive seizures two years before the patient was admitted to the hospital. During this period of time, he was repeatedly examined. The dimensions of the volumetric formation remained unchanged. Based on the data obtained, it was not possible to accurately verify the type of tumor. Anticonvulsant therapy was ineffective. The patient underwent surgery - endoscopic partial removal of the tumor (biopsy) and opening of the tumor cyst through the left lateral ventricle using intraoperative navigation. Clinical improvement in the patient's condition was achieved. After the operation, the headaches and the seizures stopped.

[Embolization of cerebral aneurysms in acute period of hemorrhage complicated by the development of vasospasm].

Results of endovascular treatment of cerebral aneurysms in acute period of hemorrhage complicated by the development of vasospasm in 80 patients were analyzed. The results of treatment of patients with vasospasm were worse. The appearance of vasospasm did not depend of the severity of the patient's state, so all the patients independent on their state need prophylactic measures against this complication. Based on the analysis a strategy of embolization of aneurysms in acute period of hemorrhage complicated by the development of vasospasm was worked out.

[Minimally invasive surgery of patients with hypertensive intracerebral bleedings].

An analysis of results of surgical treatment of 79 patients aged from 41 to 72 years with hypertensive intracerebral hematomas of supratentorial localization has shown that results of surgical treatment depended on the severity of the patients' state, the degree of impairment of consciousness, volume and localization of hematoma, ventricular hemorrhage and in less degree on the terms of operation and the degree of displacement of the median structures of the brain. The endoscopic techniques proved to be preferential in hematomas of the lateral and mixed localizations with the volume not more than 60 cm3. The developed method using a cannula allowed abandon open operations in most patients with the lateral and mixed hematomas. The postoperative lethality became less by 9.9%.

[Assessment of implication of transcranial ultrasonography in the diagnostics of acute disturbances of cerebral blood circulation in adults].

Implication of transcranial ultrasonography (TUS) in diagnostics of acute disturbances of cerebral blood circulation (ADCBC) was studied in 324 subjects, aged from 20 to 83 years, including group I (208 subjects without neurological disturbances), group II (56 subjects without the structural intracranial changes which, along with TUS, underwent MRT), group III (60 patients with diagnosis of ADCBC which underwent TUS and then CT of the brain). The brain areas where intracranial hemorrhages (ICH) were most often localized in hemorrhage stroke (HS) were found in 166 subjects (80%) of group I. The second and third cerebral ventricles were seen in 187 (90%) people. The third ventricular was seen in 19 patients (the effectiveness was corresponded to Echo-EG). The comparison of US-, CT- and MRT-images did not reveal significant differences as in the total assessment of the intracranial structural state of the brain as well in the most relevant measurements. TUS revealed no significant changes in 40 patients from group III but the diagnosis of infarction was confirmed by CT. The specific US signs of ICH were found in HS. In 19 patients the CT revealed and verified the ICH of supratentorial localization. In conclusion, TUS with using portative US equipment provides the possibility of screening-diagnostics and monitoring of ICH in strokes.
