Venous aneurysm of the cephalic vein: report of a case
1Department of Cardiovascular Surgery, Akita University, Hondo, Japan.
Insights
This study details a rare venous aneurysm of the cephalic vein in a Japanese woman. Histology showed reduced muscle and elastic fibers, suggesting a congenital defect contributed to its development.
Area of Science:
- Vascular Surgery
- Histopathology
- Anatomy
Background:
- Venous aneurysms are uncommon vascular malformations.
- The cephalic vein is a major superficial vein in the arm.
- Surgical excision is a treatment option for symptomatic venous aneurysms.
Observation:
- A rare case of a venous aneurysm in the left cephalic vein is presented.
- The patient was a 41-year-old Japanese woman.
- The aneurysm was successfully excised under local anesthesia.
Findings:
- Histological examination of the aneurysm wall revealed a significant decrease in both the number and size of muscle and elastic fibers.
- These structural changes suggest a potential weakness in the vein wall.
Implications:
- The findings suggest that a combination of endophlebohypertrophy and a congenital focal defect in elastic and muscle fibers may contribute to venous aneurysm formation.
- This case highlights the importance of considering congenital factors in the etiology of venous aneurysms.
- Further research into the underlying mechanisms of venous aneurysm development is warranted.
Abstract:
We herein report the rare case of a 41-year-old Japanese woman in whom a venous aneurysm in the left cephalic vein was excised under local anesthesia. Histological examination revealed significant diminution in the number and size of muscle and elastic fibers in the aneurysm wall. Conceivably, a combination of endophlebohypertrophy and a congenital focal defect of the elastic and muscle fibers might have contributed to the development of this venous aneurysm.
