Method for myocardial revascularization in case of coronary artery disease

FIELD: medicine.

SUBSTANCE: combined effect on the myocardium is provided, including laser treatment and intramyocardial administration of autologous bone marrow stem cells (ABMSC). Through channels in the left ventricular wall in the myocardial ischemia area or areas are performed, with diameter of 0.3-1.0 mm and frequency of one channel per 1 cm2 of the left ventricle wall. Each channel is perpendicular to the left ventricle outer wall surface in the channel forming area. Channels are formed using the impact of CO2 laser, with a power of 800-1000 W and pulse duration of 20-50 ms. The pulse duration is chosen sufficient to form a channel by one pulse within the refractory period of the cardiac cycle. Then, 200 l of a solution containing 8.3 million of ABMSC is administered around each channel along its entire length using one injection. The needle is directed in the avascular zone at a distance of 1-2 mm from the outer channel wall. ABMSC is introduced when extracting the needle.

EFFECT: reduction of intervention trauma, while maintaining its efficiency, reducing the volume of fluid injected with ABMSC, as well as application of one pulse to form a through channel in the myocardium, prevention of intraoperative complications and induced arrhythmia due to the laser pulse impact by forming channels in the myocardium within the refractory period of the cardiac cycle.

SUBSTANCE: transurethral bladder resection enables the exposure of tumour bed tissues to pulse laser light of wave length 970 nm and emitting power from 10 to 15 Wt. The exposure involves contacting a light guide to bladder wall wound tissues until visualising the coagulation changed within the contact exposure. That is combined with advancing the light guide spirally from the wound periphery to the tumour bed centre. A method involves improving the therapeutic effect by preventing the tumour recurrences, preventing erythrocyturia and developing complications caused by intraoperative complications, as well as preventing complications caused by the deep thermal exposure on the bladder wall.
