Abstract

None:

We report a case of a 30-year-old female with bilateral lower extremity weakness where computed tomography angiography (CTA) demonstrated a rare variant of abdominal aortic visceral branching pattern with a common trunk arising from the aorta subsequently dividing into celiac axis, superior mesenteric artery, and bilateral renal arteries. Additionally, significant stenosis was seen involving abdominal aorta distal to this common trunk suggesting midaortic syndrome. A hypertrophied arc of Riolan was also noted. This is an exceedingly rare anatomical variant discovered on CTA reflecting pivotal role of imaging in identifying such variant anatomy which can attribute to patients' symptoms and guide further management.

Abdominal Aorta

Abdominal 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.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Thoracic Aorta

Thoracic 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,...

Veins of the Abdomen and Pelvis

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Arteries of Lower Limbs

Arteries 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...

The Arch of Aorta

The 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...

Anastomoses

Anastomoses

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.
Arterial Anastomosis: These occur between arteries. They...
