Super-selection intubation can not only significantly improve the efficacy of peripheral intervention treatment, but also greatly reduce surgical complications. However, during the treatment of peripheral vascular intervention (such as liver tumor arterial chemotherapy embolism, hemoptysis bronchial arterial embolism, gastrointestinal hemorrhagic gastrointestinal arterial embolism, etc.), vascular mutation is often large, and there are many branches, and the direction of blood flow is into the direction of blood flow, the horns are even reverse, and even the use of straight-headed microstructures will have difficulty interpolation difficulties or even failure, which increases the risk of surgery and affects safety treatment. To overcome this, pre-plasticized microcatheters have emerged, among which the InstantPass Swan-Neck Microstructure is a catheter with a head-end morphology similar to Cobra. Our research aims to explore the feasibility, safety, and technical advantages of the use of swan-neck microcatheter in peripheral vascular hyperboloid intubation. Materials and Methods: From January 2023 to March 2024, 31 patients with swan-neck microstructure were used in the peripheral vascular intervention therapy outside the hospital. Among them, there were 23 men and 8 women, aged 32 - 81 years old, an average (55 ± 13) years, and the average irradiation time was 35.1 ± 24.7 minutes. 10 cases of iodide oil arterial chemotherapy embolism, 7 cases of microspheres of hepatic arteries, 3 cases of gastric duodenal artery selective embolism, 3 cases of vein embolism with esophageal stomach, and 2 cases of sperm varicose vein embolism, 2 cases of selective embolism of the intestinal membrane, 2 cases of uterine arteries embolism, and 2 cases of renal arterial embolism. 11 of these patients switched to the swan-neck microstructu展开更多
