Summary
Pulmonary hilum anatomy shows significant variations, particularly on the left side, impacting lung lobectomy procedures. Understanding these anatomical differences is crucial for successful surgical outcomes.
Area of Science:
- Anatomy
- Thoracic Surgery
Background:
- Pulmonary hilum variations are critical knowledge for lung lobectomy.
- Anatomical understanding aids surgical planning and patient safety.
Purpose of the Study:
- To investigate the morphological and morphometric variations of the pulmonary hila in adult cadaveric lungs.
- To compare variations between left and right pulmonary hila.
Main Methods:
- Studied 54 left and 49 right adult cadaveric lungs.
- Recorded morphologic and morphometric details of the pulmonary hila.
- Noted variations in the number and arrangement of hilar structures.
Main Results:
- Classical pulmonary hilum anatomy observed in 35.19% of left and 40.82% of right lungs.
- Higher incidence of morphological variations on the left (64.81%) versus right (59.18%) hilum.
- Identified variations in bronchi, pulmonary arteries, and veins, with specific counts and measurements, and found significant correlations between lung and hilum dimensions.
Conclusions:
- Pulmonary hilum morphology is highly variable.
- These variations have significant implications for pulmonary resection surgeries.
- Detailed anatomical knowledge of pulmonary hila is essential for thoracic surgeons.

35.9K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
