METHOD FOR CLAMPING OF OPEN ARTERIAL DUCT IN NEWBORNS Russian patent published in 2017 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: skin is cut together with subcutaneous fat in the projection of the fourth intercostal space on the left behind the scapula in a muscle-free region, 1.5-2 centimeters long, muscles are bluntly exfoliated, ribs are separated. A self-fixing retractor is installed after instrumental detachment of the mediastinal pleura. The pleural cavity integrity is retained. The retractor is used to push the lung forward and to identify the vagus nerve and the recurrent nerve, the left subclavian artery, using them as anatomical landmarks for arterial duct detection. Mobilization of the latter is limited by allocation of the upper and lower duct edges. The Small (S), Medium (M) or Medium-Large (ML) clamp is applied using a clamp-applicator with a diameter of 5 or 10 mm. During clamping, two or more clamps may be applied. In particular cases, a retractor is used that represents an elongated plate curved longitudinally under the obtuse angle with formation of two sections of greater and smaller lengths connected by a curved section. The latter is connected with a line of smaller length through a cervix. At that, the length of the neck is 1.5-2 of the shorter length.

EFFECT: method allows to reduce the invasiveness of surgical intervention, pre-and postoperative load, to review the area of intervention, prevent complications, preserve the residual bloodflow in the arterial duct through the use of original extrapleural mini PDA access, as well as selection and clamping methods for newborns.
