Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an intravascular false lumen plugging support.
Technical Field
In the present invention, the term "proximal" refers to the end closer to the heart in the direction of blood flow, and "distal" refers to the end farther from the heart in the direction of blood flow.
Aortic disease is a group of cardiovascular diseases that seriously threaten human health, in which aortic dissection is a catastrophic disease. The aortic dissection refers to a true-false separation state of two cavities formed by tearing blood in an aortic lumen from an aortic intima into an aortic media to separate the media and expanding the media along the major axis of the aorta. At present, the method of adopting the endoluminal isolation technique and using the covered stent for treating the aortic dissection disease is a great progress of aortic dissection disease treatment in recent years, and compared with the traditional treatment method, the method has the advantages of slight trauma, few complications, low mortality and the like. The technique is to implant a blood vessel stent in the aorta true lumen to block the near-end crevasse of the aorta and avoid the blood flow from the near-end primary crevasse to continuously flow into the false lumen. However, the distal end of the aortic dissection in the chronic stage generally has a plurality of lacerations, and a plurality of distal lacerations are far away from the proximal primary lacerations and close to the important branch artery, and the size of the lacerations is larger than 5mm, so that the covered stent in the true lumen cannot effectively close the distal lacerations. This distal breach will become an inflow channel for the prosthetic lumen, rendering the prosthetic lumen ineffective for thrombolysis and even allowing the prosthetic lumen to continue to expand until the aorta ruptures.
At present, doctors clinically use longer covered stents to plug distal lacerations, the technology is easy to cause spinal ischemia, and the distal lacerations close to important branch arteries cannot be plugged. Meanwhile, the distal laceration is clinically blocked by using the congenital heart disease blocking device, so that the risk of falling off of the blocking device exists, and the distal laceration closer to the important branch artery cannot be blocked. In addition, foreign clinicians implant the artificial cavity with the vascular stent after the repacking and then implant the shutoff that the mode of plugging device carries out distal end breach blood backflow for the faster thrombus of artificial cavity, but this technique has the support compliance relatively poor, causes the risk of new breach of blood vessel easily, has also influenced postoperative artificial cavity shrink simultaneously, the effect of true chamber remolding.
