Summary
Pulmonary sequestration, a rare lung malformation, typically arises from the aorta. This case details an infant’s extralobar sequestration with a unique arterial supply from the innominate artery, diagnosed non-invasively with CT scans.
Area of Science:
- Medical imaging
- Pediatric surgery
- Thoracic medicine
Background:
- Pulmonary sequestration is a rare congenital anomaly involving abnormal lung tissue with anomalous vasculature.
- Typically, the arterial supply originates from the descending thoracic or abdominal aorta.
Observation:
- A 5-week-old infant presented with an extralobar pulmonary sequestration.
- The anomalous arterial supply was found to originate from the innominate artery.
Findings:
- This specific arterial supply pattern from the innominate artery is exceedingly rare, with only one prior case documented.
- Helical CT scanning effectively visualized the malformation and its vascular supply.
Implications:
- This case expands the known vascular supply variations for pulmonary sequestration.
- Helical CT scanning offers a non-invasive alternative to arteriography for diagnosing pulmonary sequestration.
- Accurate pre-operative imaging is crucial for surgical planning in pediatric congenital lung malformations.

01:21Coronary Circulation
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:15Thoracic Aorta
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
01:25Abdominal Aorta
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
01:19Overview of Pulmonary Circulation
The pulmonary circulation is a vital system in our body that acts as a bridge between the respiratory and cardiovascular systems. It serves as a transport network for deoxygenated blood from the heart to the lungs and then returns oxygen-rich blood back to the heart.
The process begins with the right ventricle of the heart pumping deoxygenated blood into the pulmonary trunk. This large vessel extends about 5 centimeters before splitting into the left and right pulmonary arteries. These arteries...
