In CTO, both forward and reverse techniques will be applied to the balloon. At present, in the interventional treatment of coronary bifurcation lesions, the necessary stent technology is used in a high proportion, while the balloon protection technology can ensure the continuous opening of the collateral vessels during the operation. However, compared with the guidewire protection technology, the balloon protection technology of the collateral vessels is more complicated to operate. Generally speaking, the balloon protection technology is recommended to predict the high risk of branch occlusion after the main branch stent is implanted under the condition of simple guide wire protection for the diseased parts with large blood vessels, large branch domination range and small bifurcation angle. Balloon collateral protection technology is a preventive measure. When collateral occlusion occurs after the stent is released from the main branch, the operator can calmly handle the occlusion and ensure the blood supply of collateral.

Selection of balloon in CTO opening

In CTO interventional therapy, the reasonable selection of balloon can effectively improve the success rate of CTO-PCI. The basic principles to be followed when selecting pretreatment balloons are as follows:

Balloon with good selectivity: Generally, a single embedded marker balloon with super-slippery coating on its surface and small outside diameter is selected. When passing through calcified lesions, a balloon with short and hard head is selected, and when passing through tortuous lesions, a balloon with small and round head is preferred.

Select the balloon with strong pushing force: strong pushing force makes the transmission more efficient;

Choose a balloon with better flexibility and tracking.

With the development of ADR technology, related instruments are constantly updated and iterated.

As one of the imported balloons, CTO balloon dilation catheter has outstanding performance in the success rate of CTO opening. Its smooth and round head design is not easy to be calcified, which not only improves the passability, but also improves the durability of the head, and also reduces the damage to blood vessels and stent structures.

Operation of the balloon

1. Try a long ball bag with a small Profile and a single marker band. The mark is the largest position of capsule Profile, and it is often the most difficult place to pass through. Selecting the long bulb can make the part in front of the marker band as deep as possible into the lesion. 2. Keep the forward pushing force, fill the balloon and expand the proximal fiber cap as much as possible. 3. Repeat the Hammer action. 4. Replace the new balloon.

As the last "fortress" of CTO PCI, its clinical cases are complex and changeable, and there are often various difficulties in actual treatment. However, with the progress of technology and the establishment of multi-disciplinary cooperation mode, it provides a better operating platform for the majority of interventional physicians. Intervening physicians should actively learn new technologies and base themselves on solid basic theories, make sufficient preparations while being courageous and practical, and constantly try to overcome the difficulties in the opening of CTO. The selection and application of the balloon is an important link in the opening of CTO. Accurate operation of the balloon can greatly improve the opening efficiency of CTO. Therefore, every surgeon who opens CTO needs to master the specification and skills of CTO balloon, and apply it flexibly in clinic to bring better surgical effect to patients. At the same time, KOSSEL provides the most professional CTO balloon dilation catheter, Which could make you rest assured absolutely, and welcomes your consultation.
