Abstract
With the rapid development of imaging technology and the improvement of people's health awareness, more early lung cancers are found. For very early lung cancer (mainly manifested as ground glass nodules), lobectomy is still the standard surgical treatment for lung cancer, and segmental resection has been used clinically as a treatment method. 3D navigation is an effective tool for precise lung segment and sub-segment resection. Three-dimensional vascular reconstruction technology is an advanced imaging technology. Accurate segment resection under thoracoscopy is considered the best surgical treatment for early stage lung cancer. It is difficult to accurately estimate the morphology, nature and other characteristics of the tumor and its surroundings by two-dimensional imaging alone. Therefore, the precise resection operation adds great difficulty and risk to the surgeon. In recent years, 3D navigation and vascular reconstruction techniques have been widely developed and applied in the medical field, and they are rarely used in thoracic surgery. This article has conducted a more in-depth study on the application of 3D navigation technology and vascular reconstruction technology in precision lung resection, and has achieved certain research results.
Highlights
In the past 20 years, with the development of biomedicine and the rise of evidence-based medicine and humanistic medicine, the concept of surgery has been constantly changing
2.2 Vascular reconstruction technique Three-dimensional CT bronchial vascular reconstruction technology refers to the thin-layer enhanced CT scan of the patient, the obtained two-dimensional image is extracted and segmented by software to construct threedimensional geometric figures, and a three-dimensional digital model is formed through computer visualization technology to locate an imaging technique for the location of the lesion [13]
Some scholars conducted a study on 68 patients with early stage lung cancer who underwent thoracoscopic precision segmentectomy
Summary
In the past 20 years, with the development of biomedicine and the rise of evidence-based medicine and humanistic medicine, the concept of surgery has been constantly changing. The lung tissue has a certain degree of collapse and centripetal or rotational deformation, and in the thoracoscopic view, the operation field cannot be fully observed due to the limitation of the visual field [5] For this reason, in order to be safe and effective, it is very important to understand the branch form of the blood vessel before surgery. 2.2 Vascular reconstruction technique Three-dimensional CT bronchial vascular reconstruction technology refers to the thin-layer enhanced CT scan of the patient, the obtained two-dimensional image is extracted and segmented by software to construct threedimensional geometric figures, and a three-dimensional digital model is formed through computer visualization technology to locate an imaging technique for the location of the lesion [13]. Threedimensional CT bronchial vascular reconstruction software commonly used in my country includes IQQA, Osiri X and so on [16]
