BACKGROUND: Obtaining the left internal mammary artery (LIMA) is currently done using an electrocautery knife under small incisions and direct visualization. This technique is associated with greater damage to the chest wall, poor hemostasis with the scalpel, and multiple use of titanium clips. In contrast, thoracoscopic ultrasonic knife acquisition produces low heat loss to the surrounding tissue.
METHODS: 32 cases of MICABG patients who underwent LIMA procurement in our hospital during 2023.01-2023.05 were randomly divided into two groups: the experimental group was to use ultrasonic knife to obtain the LIMA under the full thoracoscopic procedure, and the control group was to use the electro-knife to obtain the LIMA under the direct vision of the small incision, to compare and analyze the baseline information of patients in the two groups, the length of the LIMA obtained, the blood flow, the PI, and the time, to evaluate the feasibility and safety of obtaining theLIMA using ultrasonic knife under total thoracoscopy.
RESULTS: A total of 32 patients were selected, including 18 patients in the experimental group and 12 patients in the control group, aged around 65 years old. There was no significant difference in LIMA acquisition length, time, blood flow and PI between the two groups, and the number of titanium clips used intraoperatively in the experimental group was significantly less than that in the control group (0.2 vs 16.6).
CONCLUSIONS: Total thoracoscopic acquisition of the LIMA using ultrasonic knife has certain feasibility and safety.
