FIELD: medicine.
SUBSTANCE: method is implemented using a device for measuement of pressure and introduction of medicinal substances into the blood vessel aneurysm in several steps. The vessel is punctured with installation of an introducer therein. A conductor with a stopper at the distal end is introduced, so that the stopper is located in the distal part of the aneurysm cavity. The proximal end of the conductor is inserted into the end opening of the distal end of the tube of the said device. The proximal end of the conductor is withdrawn through the distal lateral opening of the device tube. To the proximal end of the device a detachable hollow tube is attached, or a device with an attached detachable tube is initially used. The device is moved distally along the conductor until the distal end of the device reaches the above stopper. The device is moved in the distal direction until the proximal end of the device reaches the aneurysm cavity. The stent graft is implanted so that the said device is located between the aneurysm wall and the stent graft wall. Pressure in the aneurysm is controlled and, if necessary, a drug substance is administered. Conductor, detachable tube, device and introducer, or only conductor, detachable tube and introducer are removed. According to the second version, the method for blood vessel aneurysm treatment is implemented using a device for blood pressure measurement and medicinal substances administration to the blood vessel aneurysm in several steps. The vessel is punctured with installation of an introducer therein. A conductor with a stopper at the distal end is introduced, so that the stopper is located in the distal part of the aneurysm cavity. The proximal end of the conductor is inserted into the end opening of the distal end of the tube of the said device. The proximal end of the conductor is withdrawn through the distal lateral opening of the device tube. The proximal end of the conductor is inserted into the extreme proximal lateral opening of the device tube. The proximal end of the conductor is withdrawn from the proximal end of the device tube. To the proximal end of the device a detachable hollow tube is attached, or a device with an attached detachable tube is initially used. The device is moved distally along the conductor until the distal end of the device reaches the above stopper. The device is moved distally along the conductor until the proximal end of the device reaches the aneurysm cavity. Conductor is removed. The stent graft is implanted so that the said device is located between the aneurysm wall and the stent graft wall. Pressure in the aneurysm is controlled and, if necessary, a drug substance is administered. Detachable tube, device and introducer, or only detachable tube and introducer are removed.
EFFECT: simplified course of surgical intervention and improved immediate and long-term results of treatment due to accurate and safe positioning of the device for pressure measurement and medical substance delivery through provision of a well-controlled device insertion process.
