Phlebosclerosis: An overlooked complication of varicose veins that affects clinical outcome: A case report.

BACKGROUND

Phlebosclerosis is a common age-related fibrotic degeneration of the venous wall. It is a disorder rather than a disease, which may cause venous dysfunction and even venous thrombosis. It is rarely reported in patients with varicose veins.

CASE SUMMARY: The present report describes the case of a 70-year-old man with varicose veins, vitiligo, and phlebosclerosis. Venous angiography revealed blood reflux in the superficial and deep veins. The patient underwent surgery to remove the saphenous veins. During the operation, a calcified vein resembling a wooden stick was found, which was surprisingly extracted from the thickened venous wall. A cross-section of this wooden stick-like vein revealed venous fibrosis and calcification, obvious thickening of the venous wall, extensive collagen deposition on the venous wall, hyaline degeneration, and venous sclerosis causing closure of the venous lumen.

CONCLUSION

This is probably the first report of a wooden stick-like structure being found in the venous wall in patients with varicose veins and venous ulcers. Phlebosclerosis can be observed in the late stage of varicose veins complicated by frequent infections and worse clinical outcomes. Therefore, it is important to be aware of this condition and address it rather than overlook it.
