Vibration Method for Removal of Hypertensive Intracerebral Hematomas

Background. The issues of surgical treatment of hypertensive intracerebral hematomas are complex and far from resolved. The current trend in neurosurgery is the use of minimally invasive operations, the purpose of which is the most complete removal of the hematoma with minimal damage to the surrounding brain tissue. Purpose of the research is to propose a new device and method for the removal of hypertensive intracerebral hematomas. Material and methods. A blunt-ended cannula 100 mm long was used, which has a constant diameter of 10 mm over 90 mm, after which it conically narrows. At the border of the narrowing, the cannula has 3 longitudinal symmetrical oval holes 8 mm long and 6 mm wide. A micro vibration motor is located flush with the holes inside the cannula, which is an electric motor on the shaft of which there is an unbalanced load in the form of an eccentric. The device operates as follows: the truncated end of the cannula is punctured and positioned in the center of the hematoma. The vibration motor is connected to a power source with a voltage of 3.0 to 4.5 V DC. The vibration creates a limited vibrating circuit, which destroys and crushes the hematoma clots through the holes in the cannula. A metering peristaltic pump is connected to the outer end of the cannula to remove the blood clots. Results. A new device and method for removing hypertensive intracerebral hematomas are described. Preliminary data from a pilot study showed the possibility of using the device and method in patients with this pathology. Conclusions. A new vibration method for removing intracerebral hematomas is proposed. Further accumulation of clinical material and determination of indications for the use of the device and method are necessary.
