Radiology Case Reports
|June 23, 2021
Summary
A rare carotid diaphragm, a condition causing artery stenosis, was found in the common carotid artery (CCA) of a 59-year-old woman experiencing transient syncopes. This is only the third reported case of a CCA diaphragm.
Area of Science:
- Vascular Surgery
- Neurology
- Radiology
Background:
- Carotid diaphragm is a rare congenital anomaly that typically causes stenosis in the internal carotid artery (ICA).
- Symptoms often include transient ischemic attacks (TIAs) and ischemic stroke, particularly in middle-aged patients.
- Over 50 cases of ICA stenosis due to carotid diaphragm have been documented.
Observation:
- This article presents a rare case of a common carotid artery (CCA) diaphragm.
- The condition was identified in a 59-year-old female patient presenting with transient syncopes.
- This represents the third reported instance of a CCA diaphragm in medical literature.
Findings:
- The patient exhibited symptoms of transient syncopes.
- Diagnostic imaging revealed a diaphragm causing stenosis in the common carotid artery.
- This finding highlights the potential for carotid diaphragms to occur in the CCA, not exclusively the ICA.
Implications:
- This case expands the known anatomical locations for carotid diaphragm formation.
- It underscores the importance of considering CCA involvement in patients with unexplained syncopal episodes or stroke symptoms.
- Further investigation into the embryological origins and clinical significance of CCA diaphragms is warranted.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.

102
Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

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.

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
