1 Μαΐ 2024 · The pulmonary arteries accompany the bronchi on their course towards the periphery and thus there are lobar, segmental and subsegmental branches. Differentiation can be made by tracing the arterial divisions in correlation to the bronchi.
23 Ιουλ 2024 · Bronchopulmonary segmental anatomy describes the division of the lungs into segments based on the tertiary or segmental bronchi. Gross anatomy. The trachea divides at the carina forming the left and right main stem bronchi which enter the lung substance to divide further.
11 Αυγ 2024 · Identify the appropriate indications for segmental lung resection in patients with early-stage non–small cell lung cancer and other localized pulmonary diseases. Screen patients for segmental lung resection eligibility based on their pulmonary reserve and comorbid conditions.
Primary lung cancers are classified broadly as non-small cell lung carcinoma (NSCLC) or small cell lung carcinoma (SCLC). The former makes up ~85% of cases and the latter 15%. SCLC is distinguished by rapid growth rate, early regional lymph node dissemination, and spread to distant sites. 8 , 9 Survival percentages for lung cancer drop ...
The segmental bronchus that runs down the center of the segment gives rise to two or three subsegmental bronchi. Further branching of the bronchial tree occurs until the last division, which is called the “lobular bronchus” because it ends in the pulmonary lobule (physiologic unit of the lung).
1 Μαΐ 2021 · The lobar bronchus of the LUL has an upper branch which bifurcates into apical and posterior bronchi (B1 + B2) usually with a common origin and anterior bronchus (B3); and a lower or lingular branch which bifurcates into superior (B4) and inferior (B5) bronchi.
23 Ιουν 2021 · Moreover, sublobar resection, particularly segmentectomy, is considered a definitive surgery for small lung cancers, with non-inferior prognosis and better postoperative lung function than lobectomy [6].
