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...

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...

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...

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,...

Radiology

Background:

Aneurysms of the lateral sacral artery are exceptionally rare vascular abnormalities.
Patients with a history of renal transplant may present with complex conditions requiring comprehensive diagnostic approaches.

Observation:

A 46-year-old female with a history of renal transplant presented with cauda equina syndrome symptoms, including bowel/bladder incontinence and decreased perianal sensation.
During attempted laminectomy and diskectomy for a presumed prolapsed disk, severe intraoperative hemorrhage occurred, leading to surgical abortion.

Findings:

Magnetic resonance imaging and angiography confirmed a lateral sacral artery aneurysm as the likely cause of the hemorrhage.
The aneurysm presented as a diagnostic challenge, mimicking or complicating the presentation of a prolapsed lumbar disk.

Implications:

This case underscores the necessity of considering lateral sacral artery aneurysms in the differential diagnosis for patients presenting with cauda equina syndrome, particularly those with a history of renal transplantation.
Thorough pre-operative assessment, including advanced imaging, is crucial for identifying such rare vascular pathologies to guide appropriate treatment strategies and prevent life-threatening hemorrhage.
