Abstract
We present in this paper an in-depth study and analysis of bronchiectasis haemoptysis by multirow CT tomography and a multifaceted treatment and analysis of the interventions monitored by the scan. Although coronary CT is of great clinical value in the diagnosis and monitoring of coronary artery disease, the potential radiation damage caused by coronary CT should not be underestimated because CT imaging is based on X-rays and the actual effective dose is 5–30 mSv, which is reported in the literature to be high when using conventional imaging modalities for coronary CT. Although there is no direct evidence of a definite causal relationship between X-ray exposure during CT examinations and tumorigenesis, theoretically, even small doses of radiation exposure may pose some potential health risk. Therefore, in clinical practice, coronary CT examinations should be performed in strict compliance with the radiation protection rule “as low as reasonably achievable” (ALARA) recognized by the radiation industry. For longitudinal openings in the range of 0° to 59° and transverse openings in the range of 0° to 44°, the CB2 catheter is significantly more stable than the MIK catheter, and for longitudinal openings in the range of 60° to 119° and transverse openings in the range of 0° to 44°, the CB2 catheter is more stable than the MIK catheter. For longitudinal openings from 0° to 120° and lateral openings from 45° to 90°, there was no significant difference in cannulation stability between the CB2 and MIK catheters. There was a potential tendency for MIK cannulation stability to be higher than CB2 for longitudinal openings in the range of 120° to 180° and lateral openings in the range of 45° to 90°, but there was no significant difference.

Most scholars believe that either primary or metastatic lung cancer is generally supplied by bronchial artery (BA), which is the most common and important responsible vessel involved in lung cancer, while the pulmonary artery does not participate in blood supply, Journal of Healthcare Engineering and only a few reports can have pulmonary circulation to participate in lung cancer blood supply [4]
The blood flow is blocked and the blood vessels rupture causing massive haemoptysis. Both FIB and D-dimer increased significantly in patients after surgery compared to preoperative levels, and the concentrations were positively correlated with the efficacy of surgery, suggesting that surgery in BAE activates the coagulation system and thrombus formation contributes to sealing the ruptured vessel, which is positively correlated with the efficacy of surgery. e results of this study indicate that fibrinogen and D-dimer concentrations can be used as clinical indicators to assess recurrent haemoptysis after BAE
Summary
We present in this paper an in-depth study and analysis of bronchiectasis haemoptysis by multirow CT tomography and a multifaceted treatment and analysis of the interventions monitored by the scan. With the rapid development of CT imaging equipment, the display of microstructures has reached the millimetre level; coupled with the continuous improvement of CT-related postprocessing technology, CTA has been recognized by increased physicians because of its powerful spatial display capability, especially for microvascular lesions, which can show the origin and course of dilated bronchial arteries and the relationship between vessels and lesions. It can show whether there is extrapulmonary circulation involved in the haemoptysis supply so that the responsible vessels for the haemoptysis can be detected in a one-stop scan
