METHOD FOR VIDEOTHORACOSCOPIC EXTRAVASAL OCCLUSION OF OPENED ARTERIAL DUCT Russian patent published in 2005 - IPC

FIELD: medicine, cardio-vascular surgery.

SUBSTANCE: one should introduce three trocars into patient's thorax, perform videoendosurgical isolation of anterior, superior and inferior ductal walls followed by squeezing the duct with clips. After isolating anterior, superior and inferior ductal walls one should measure external diameter of its narrowest part and match a clip in accordance with the ratio of clips' sizes to external diameter of a vessel. At this ratio, external diameter of the vessel of 3.0 mm corresponds to clips of 5.0 mm and 6.0 mm in closed state, in case of external diameter of vessels being 3.5 mm, 4.0 mm and 5.0 mm one should match clips of 8.7 mm and 9.0 mm length, and at vessels' diameter being 5.5 mm and 6.0 mm it is necessary to take clips of 12.0 mm length. To perform clipping one should substitute instrumental trocar for that for clip-applicator in the desired point. As a result, it is possible to decrease traumaticity of operative interference, decrease cases of intraoperational hemorrhages and lesion of recurring-laryngeal nerve, save residual circulation or renew it along opened arterial duct.

EFFECT: higher efficiency.
