Introduction
Under normal circumstances, stents are made of shape-memory metal and, once placed inside a blood vessel, provide stable fixation, so displacement rarely occurs. If you wish to check whether the stent has shifted, a bronchoscopy is generally recommended. The specific procedure is as follows: 1) Administer lidocaine via nebulized inhalation for anesthesia. 2) After the anesthesia takes effect, have the patient lie flat.
Under normal circumstances, stents are made of shape-memory metal and, once placed in a blood vessel, remain securely fixed without displacement. If one wishes to check whether the stent has shifted, bronchoscopy is typically used. The specific procedure is as follows:
1. Administer lidocaine via nebulized inhalation for anesthesia.
2. After the anesthesia takes effect, have the patient lie flat.
3. Gently and slowly insert the bronchoscope through the patient's mouth or nose into the nasopharynx, advancing gradually until reaching the lower pharynx.
4. Assess whether displacement has occurred based on the findings. If emphysema is observed, this may indicate that the stent has migrated into the distal bronchial lumen and should be promptly removed.
5. After completing the examination, withdraw the bronchoscope.
If any abnormalities are detected during the examination, it is recommended to seek medical attention promptly and receive treatment under the guidance of a qualified physician to avoid delays in diagnosis and treatment, which could impair recovery.
