Summary
A dilated inferior mesenteric artery provided collateral blood flow to the lower leg due to celiac axis stenosis in an elderly woman with peripheral vascular disease.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
Background:
- Peripheral vascular disease (PVD) can lead to critical limb ischemia.
- Celiac axis stenosis is a potential cause of visceral and non-visceral arterial compromise.
Observation:
- An 83-year-old woman with PVD presented with left lower extremity discomfort.
- Peripheral multidetector CT angiography was performed for evaluation.
Findings:
- CT angiography revealed a significantly dilated inferior mesenteric artery (IMA).
- The dilated IMA was identified as a crucial source of retrograde collateral perfusion.
- This collateral flow compensated for a stenosis in the celiac axis.
Implications:
- The IMA can serve as a vital collateral pathway in cases of proximal arterial stenosis.
- Understanding these collateral pathways is essential for managing complex vascular disease.
- This case highlights the importance of comprehensive vascular imaging in PVD evaluation.

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.

01:16Blood Supply to the Digestive System
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

01:14The Aorta
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

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,...
01:19Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

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.
Encircling the heart, the coronary arteries form a ring-like structure before...
