Insights
A rare Kommerell diverticulum, a type of incomplete vascular ring, caused vomiting and stridor in an infant. Surgical treatment was successful, highlighting the importance of embryological understanding for vascular ring malformations.
Area of Science:
- Cardiology
- Pediatric Surgery
- Medical Imaging
Background:
- Vascular rings are congenital anomalies of the aortic arch system.
- Kommerell diverticulum is a rare variant, often associated with other cardiovascular abnormalities.
- Symptoms in infants can include respiratory distress and feeding difficulties.
Observation:
- An 11-month-old girl presented with vomiting and laryngeal stridor.
- A Kommerell diverticulum was identified as the cause of the incomplete vascular ring.
- While magnetic resonance imaging is typically preferred, cardiac catheterization defined the vascular ring structures in this case.
Findings:
- The patient had a Kommerell diverticulum causing an incomplete vascular ring.
- Cardiac catheterization successfully delineated the anatomy of the vascular ring.
- Surgical intervention resulted in a successful outcome for the patient.
Implications:
- This case underscores the diagnostic utility of cardiac catheterization in complex vascular ring cases.
- Successful surgical management highlights the importance of timely intervention.
- Understanding aortic arch embryology is crucial for diagnosing and managing diverse vascular ring anomalies.
Abstract:
A case of an 11-months-old girl with vomiting and laryngeal stridor is presented, and in whom a Kommerell diverticulum was demonstrated, which is a rare variant of the incomplete vascular ring. It is well known that the magnetic resonance is the best study to define this malformation. In this patient, it was the cardiac catheterization which allowed to define the structures that constituted the vascular ring. The patient was surgically treated in a successful way. The embryological knowledge of the transformations of the aortic arches offers great assistance in the understanding of all the types of vascular rings.

Large Intestine
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
