Review Case Reports
Persistent left superior vena cava: what the interventional nephrologist needs to know.
Variations in the course of the blood vessels are often incidental findings during clinical examination. Persistent left superior vena cava (PLSVC) is an uncommon anomaly, estimated to be present in about 0.3-0.5% of healthy individuals and in about 3-10% of patients with congenital heart disease. ⋯ Since it frequently goes undiagnosed because of lack of symptoms when not accompanied by other anomalies, variations of the superior vena cava should be considered, especially when central venous catheterization via the subclavian or internal jugular vein is difficult. The embryological development, diagnosis, and clinical implications of a PLSVC are therefore reviewed in this article.

Review Case Reports
Surgical excision of infected arteriovenous grafts: technique and review.
Infected prosthetic arteriovenous grafts for hemodialysis present a profound risk to patient well being. Here we present five recent cases and describe our technique for total graft excision. We also review the literature and discuss the much debated role of partial, subtotal, and total graft excision.
