Summary
Dynamic compression of the dorsalis pedis artery can mimic fixed stenosis. Positional changes during angiography confirmed this vascular phenomenon, preventing misdiagnosis and unnecessary interventions.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Interventional Cardiology
Background:
- Dynamic compression of the dorsalis pedis artery is an underrecognized vascular condition.
- This phenomenon can present as focal stenosis during specific foot positions.
- Misinterpretation can lead to unnecessary interventions for presumed atherosclerotic disease.
Purpose of the Study:
- To report a case of dynamic dorsalis pedis artery compression.
- To highlight the importance of positional maneuvers in diagnosis.
- To emphasize avoiding misinterpretation as fixed atherosclerotic disease.
Main Methods:
- Angiography was performed during foot dorsiflexion, revealing severe stenosis.
- Repeat angiography with plantar flexion demonstrated complete resolution of the lesion.
- Positional maneuvers were key to confirming dynamic arterial compression.
Main Results:
- A 52-year-old asymptomatic male presented with apparent severe stenosis of the dorsalis pedis artery.
- Stenosis resolved completely upon changing foot position from dorsiflexion to plantar flexion.
- This confirmed a diagnosis of position-dependent arterial compression.
Conclusions:
- Dynamic dorsalis pedis artery compression is a positional phenomenon.
- Positional angiography is crucial for accurate diagnosis, differentiating it from fixed atherosclerotic disease.
- Recognition prevents misdiagnosis and avoids unnecessary vascular interventions.

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

01:30Peripheral Artery Disease I: Introduction
646
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

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...
