Method for brain protection in case of carotid reconstruction during acute ischemic stroke
SUBSTANCE: degree of the internal carotid artery (ICA) stenosis is determined and the initial blood pressure (BP) is measured. If the degree of ICA stenosis on the stroke side is up to 79% or in case of contralateral ICA occlusion and initial systolic blood pressure (SBP) less than 150 mm Hg, the main stage of surgery is arterial bed clamping, common carotid artery (CCA) longitudinal dissection with transition to the ICA, temporary internal bypass (TIB) installation, arteriotomical hole suturing, TIB removal and blood flow restoration in the carotid arteries, is performed at SBP level of 100-120 mm Hg, and if the initial SBP is 150 mm Hg and more - the main stage of surgery is carried out at SBP level of 120-140 mm Hg. If the degree of ICA stenosis on the stroke side is 80% or more, the main stage of surgery is arterial bed clamping, CCA dissection with transition to the ICA, arteriotomical hole suturing, TIB removal and blood flow restoration in the carotid arteries, is performed at SBP equal to the initial SBP plus 30%, but no more than 160 mm Hg.
EFFECT: invention reduces intraoperative complications, which is achieved by SBP regulating depending on the degree of stenosis.

SUBSTANCE: planned skin incision is first configured on an anteriolateral neck surface by projection zoning of a clavisternomastoid and a neck median line to be marked with colour graphic lines. A first line extends along a medial border of the clavisternomastoid. A second line extends from a suprasternal notch to the middle of a hyoid shaft. Both of the lines are then combined by drawing a perpendicular third line from a lower border of the middle of a hyoid shaft to the medial border of the clavisternomastoid, thereby forming a projection triangle. Cutaneofascial layers, platysma and subcutaneous fat are incised along the first and third lines to cut out a musculocutaneous flap, which is brought outwards. Underlying soft tissues are dissected to an anterior surface of cervical spinal bodies by splitting subcutaneous fat between a neurovascular bundle and a pharynx, detaching an intracervical fascia, splitting perioesophageal subcutaneous fat and displacing midline organs of the neck in the medial direction, and the neurovascular bundle - in the lateral direction.
EFFECT: method enables reducing a risk of treatment-induced traumatic injuries of the midline organs of the neck, an upper laryngeal nerve, upper and lower thyroid arteries, as well as a parenchyma and an excretory duct of a submandibular salivary gland with optimising topographo-anatomical relations of the incision wound structures, thus providing a surgical angle approaching 90 degrees.

SUBSTANCE: the method is applied for the purpose to correct combined deformations of external nose due to oral-vestibular operative access. The method deals with dissecting mucosal membrane and periosteum in oral vestibule followed by separating soft tissues of the upper lip. Then one should perform internal incision along the edge of alar cartilages to connect two incisions together.

SUBSTANCE: the present innovation deals with affecting the sclera and applying deformation-correcting sutures at the background of medicinal erection. Along lateral surfaces of cavernous bodies symmetrically from both sides one should make incisions of scleral surface layer. Then comes manual derotation, moreover, at the side of derotation incision's lower edge should be shifted downwards and backwards, its upper edge - upwards and to the front, and at contralateral side the lower edge is shifted downwards and to the front, and the upper edge - upwards and backwards. After manual penile derotation one should apply sutures onto the edges of dissected scleral layer in incision area by shifting needle's puncture out towards the side being opposite to shift direction of the lower edge against incision's perpendicular axis. The quantity of incisions should be calculated by the following formula: Q = N/n, where Q - the desired quantity of incisions, N - the angle of total initial rotation, n - the angle of derotation achieved after applying sutures onto the first pair of incisions. The method enables to decrease the risk for development of either new or residual penile deformation in postoperational period.
EFFECT: higher efficiency of correction.
