Abstract：Objective: To explore the value of transthoracic echocardiography(TTE) on observation the catheter tip of the internal jugular vein long-termcatheter in hemodialysis patients. Methods: From January 2016 to July 2017, 52 hemodialysis patients with the internal jugular vein long-termcatheter undertook TTE and X-ray, to observe the catheter tip, including its position, and other complication such as thrombosis. Results: In the 52 cases, catheter tips of 49 cases could be observed clearly by TEE(94.2%). Cathetertip localization rate was 87.8%(43/49), ectopic rate was 12.2%(6/49); while catheter tips of 48 cases could be observed clearly by X-ray(92.3%), the cathetertip localization rate was 89.6%(43/48), and ectopic rate was 10.4%(5/48). There was no statistically significant difference(P>0.05). Kappa test showed a better consistence(P<0.05). Thrombosis was found in fourteen catheter tips by TTE, while none could be found by X-ray. All the ectopic severe cases were retreated to ideal position under the guidance of TTE, and the success rate was 100%. For the thrombosis patients, treatment of thrombolysis was guided. Conclusion: TTE can clearly display catheter tip, observe its position and the presence of thrombus. It can help to adjust ectopic catheter tip and evaluate thrombolysis effect. It’s noninvasive, convenient, safe, rapid and accurate. It shows an important clinical value.
