Summary
This study reports a rare case of double aortic arch with a dominant right arch, leading to pulmonary embolism and left subclavian steal syndrome. Awareness of this rare vascular anomaly is key to preventing diagnostic and treatment errors.
Area of Science:
- Cardiology
- Radiology
- Vascular Surgery
Background:
- Double aortic arch is a rare congenital anomaly of the aortic arch.
- Vascular rings can cause significant cardiovascular and respiratory symptoms.
Observation:
- A 59-year-old woman presented with dysphagia, chest discomfort, and left arm claudication.
- Imaging revealed a double aortic arch with a dominant right arch, distal left arch narrowing, descending aorta dilatation, pulmonary embolism, and left subclavian steal syndrome.
Findings:
- Diagnosis was established using pulmonary CT-angiography, highlighting characteristic features of a double aortic arch and vascular ring.
- The complex vascular anatomy contributed to the patient's presenting symptoms and associated complications.
Implications:
- Accurate diagnosis of this rare condition is critical for appropriate management.
- Misclassification can lead to surgical or endovascular complications.

01:16Vascular Spasm
1.6K
The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

21
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
