Summary
Iliac artery endofibrosis (IAE) is an underdiagnosed condition in athletes. This study highlights two distinct cases of IAE in competitive cyclists and triathletes, emphasizing varied clinical presentations and surgical interventions.
Area of Science:
- Vascular Surgery
- Sports Medicine
- Cardiovascular Research
Background:
- Iliac artery endofibrosis (IAE) is a condition involving subintimal fibrosis of the iliac artery.
- IAE is frequently associated with competitive athletics, particularly cycling.
- It remains an underappreciated diagnosis in clinical practice.
Observation:
- Case 1: A 38-year-old male cyclist presented with a groin bulge and acute monoplegia/paresthesia in the right lower extremity upon exertion.
- Case 2: A 50-year-old female triathlete experienced chronic left lower extremity claudication over four years, exacerbated by exertion.
Findings:
- The male cyclist underwent common iliac artery endarterectomy with patch angioplasty and embolectomy.
- The female triathlete received a left iliofemoral bypass for her condition.
Implications:
- These cases demonstrate the diverse clinical manifestations of IAE in athletes.
- Prompt diagnosis and tailored surgical management are crucial for restoring athletic function.
- Increased awareness of IAE is needed in the clinical evaluation of exertional leg symptoms in athletes.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

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 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...
