(57) Abstract:

The invention relates to medicine, namely to surgery, and can be used for intraoperative catheter stem sclerotherapy. Veins balloon catheter and inflate it. During insertion of the catheter from the vein injected with a sclerosing agent. The method allows to completely bleed the vein and evenly to handle the intima of the sclerosant. This increases the effectiveness of the treatment. 1 Il.

The invention relates to medicine, namely vascular surgery.

The closest is the way stem sclerotherapy catheter, consisting in that vein catheter, which inject sclerosant with simultaneous extraction of the catheter. During the introduction of carry out manual compression of the tissues in the projection Vienna to elastic bandaging(Saveliev B. C., D. Konstantinov, Bogachev C. Y. and other Modern view on the sclerotherapy of varicose veins of the lower extremities. Thoracic and cardiovascular surgery. 1992; 7-8: 4-6.)

Reliability obliteration of the vein is provided by bonding the walls of the vessel without thrombosis. To the wall grown together, the intima of the vein should be uniformly treated sclerosant, and the vessel must be compressed. Eserotherapie) above full of bleeding vessel is achieved, resulting increases the risk of postoperative complications.

The objective of the invention is to increase the efficiency sclerosing by full bleeding veins before the introduction of sclerosing substances.

This object is achieved in that before the injection of sclerosing substance into a vein injected with a balloon catheter, which was inflated on the excretion of injected sclerosing substance.

The invention is illustrated in the drawing, which shows the main phase of the operation: in the distal end of the vein (1) introducing a balloon catheter (2) with hole at end (3), after the introduction of the bag is inflated through a syringe (5), in the process of pulling the catheter on him through a syringe (4) pour in sclerosing drug.

The method is as follows.

After mobilization at the mouth of the great saphenous vein cut by 0.7-1 cm distal to the anastomosis to the femoral vein and tied up on the line of anastomosis. On the first impose a second ligature with flashing. In the distal end of the vein introducing a balloon catheter with a hole at the end, after the introduction of the balloon inflate. In the process of pulling the catheter through it pour sclerosing drug, after which the vein periasami: B. I., 57 years. Diagnosis: Varicose disease, the stage of decompensation left, with trophic disorders. Trophic ulcer of the left tibia. The diagnosis is confirmed by phlebography: Deep vein passable, valves saved. Retrograde blood flow is not defined. Large saphenous vein varix changed (diameter 1.5 cm), lower large insolvent perforating veins in the area of the inner ankle; ultrasound deep veins passable identified valvular insufficiency of deep veins of right hip and a large subcutaneous Vienna, deep veins of the leg on the left. The operation has been performed. stage 1: gas endoscopic dissection of perforating veins of the lower leg, stage 2: EAST (instead of removing the trunk of the great saphenous vein on Babcock): great saphenous vein is mobilized at the mouth, crossed at 1 cm distal to the anastomosis to the femoral vein, tied in the line of anastomosis. Over the first overlay and the second ligature with flashing. In the distal hole of Vienna introduced the balloon catheter is inflated in the process of excretion in Vienna introduced sclerosant: 3% p-p trumbower quantity 7 ml After injection of sclerosant Vienna was bandaged. During the introduction was made manual compression of the tissues in the projection of Vienna. In the postoperative period the patient received anasti, healed venous ulcer, no pain. On the 14th day in a satisfactory condition and was discharged home.

The proposed method operated 6 patients with a positive result.

Thus, the method allows to remove blood from a vein before sclerotiorum, which makes it possible, firstly, to eliminate the occurrence of deep vein thrombosis and pulmonary embolism, second: to expand the indications for IOST; sclerotherapy possible when the vessel diameter more than 2 cm, there is no dependence on the thickness of the subcutaneous fat layer (in obese patients), varicose veins under trophic disorders is not an absolute contraindication for YOST.

The way intraoperative stem sclerotherapy catheter, consisting in that vein catheter, which inject sclerosant, characterized in that it further destabilize the vein before injection of sclerosing substances by introducing a balloon catheter, which was inflated on the excretion of injected sclerosing substance.

SUBSTANCE: it is necessary to carry out draining and sanitation of restricted pleural empyema in a patient. Then the drainage should be substituted with a balloon catheter into the balloon of which under roentgenocontrol one should introduce isotonic NaCl solution with water-soluble contrast till complete filling the empyemic cavity and, correspondingly, occlusion of fistula-carrying bronchus. Filled up catheter should be kept for 7 d and then under roentgenocontrol gradually for 14-21 d one should remove the introduced solution. Te quantity of simultaneously removed solution should be determined according to the presence or absence of air drop out of empyemic cavity. After cavitary reduction the catheter should be removed. The innovation enables to provide reduction of pleural empyemic cavity along with occlusion of bronchopleural fistula and, also, prevent aerogenic contamination, stimulate granulation and subsequent cicatrisation of cavitary walls due to the pressure of balloon catheter upon them being filled by the cavitary volume.

SUBSTANCE: the present innovation deals with reconstructing permeability of occluded coronary arteries due to removing occlusion out of affected parts of arteries. So, a coronary guide with a soft tip should be applied to achieve the site of occlusion by not entering a lateral artery. As balloon catheters one should apply two-lumen ones, moreover, the first is designed to be shortened from its distal edge and ends with a balloon segment. The present balloon catheter should be applied up to the site of occlusion onset and simultaneously up to bifurcation region to install it, to be blown up to overlap the mouth of lateral artery. Then a rigid direct guide should be applied along the same balloon catheter - according to its conduit mine after preliminary removing a coronary guide with a soft tip. After directing this rigid guide through occlusion into distal part of occluded main artery and its recanalization with it is important to remove the first modeled balloon catheter and apply the second balloon catheter instead. It should be moved along occlusion to reach the center and dilate the artery. In particular case, one should remove a two-lumen tip by not interrupting the hermetic nature of a balloon catheter. The innovation enables to remove occlusion of the main artery in the site of branching, exclude "falling down" of coronary guide into lateral artery and, thus, provide the disposition of coronary guide especially in the stump in occluded artery and obtain its central position and movement strictly along the center of occlusion avoiding vascular wall traumatism due to subintimal application of coronary guide and, also, avoid arterial perforation in the site of occlusion.

EFFECT: higher efficiency.

SUBSTANCE: hemostatics and uterotonic agents are parenterally introduced. Previously folded intrauterine rubber balloon catheter with delivery and support in the form of tubular element rounded at distal end with length that is comparable to but not less than total length of uterine cavity and vagina is introduced into cavity of birth canal. Irrigation and drain tubes from elastic shape-holding material are located on external surface of balloon. Length of tubes exceeds length of tubular element for delivery and support of balloon catheter with possibility of exit beyond the limits of birth canal - from vagina. Distal ends of tubes are rounded with openings on the surface for contents outlet and collection. One of tubes is arranged with the possibility of connection with syringe for introduction of hemostatic into uterine cavity, other tubes are connected with reservoir for collection of drained liquid. Tubular element for delivery and support of balloon catheter is connected with reservoir for filling of balloon catheter with sterile liquid, the second tube installed in reservoir above liquid level is connected to manometer, and pump for pressure charging is located at its end. This device is located from entry to vagina to uterus bottom, fixing proximal end of balloon catheter with tubes in entry to vagina. Then sterile physiological solution is pumped into catheter by means of pump until visually controlled bleeding is arrested. After bleeding has been stopped, pressure value is fixed, then pressure changes are registered in filled balloon catheter, at that pressure rise is treated as restoration of uterus contractive activity, afterwards pulled pressure is reduced in successive steps down to fixed value. If pressure value in catheter drops, it is increased up to fixed value. In both cases fixed pressure of bleeding arrest is maintained for at least 30 minutes, reduction is carried out in successive steps by 10 mm of mercury column every 5-10 minutes. Hemostatics are introduced into uterine cavity by irrigation tube in appropriate doses, then all tubes are isolated for the time sufficient for creation of blood clot. If no bleeding takes place through drain tubes in process of stepwise pressure reduction, pressure is dropped, liquid is removed from balloon catheter, and it is withdrawn outside.

EFFECT: fast and efficient arrest of metrorrhagia by coverage of the whole area of possible bleeding and simultaneous additional effect at local hemostasis by introduction of medicines into uterine cavity.
