Aberdeen Surgeon Gets Number One Ranking for Renal Network 11

Dr. Christopher Larson, of Aberdeen Surgical Associates and a medical staff member of Avera St. Luke’s Hospital, has been ranked number one out of 279 vascular surgeons in the Renal Network of the Upper Midwest (Renal Network 11), which serves South Dakota, North Dakota, Minnesota, Michigan and Wisconsin.

The Centers for Medicare & Medicaid Services (CMS) has established a goal to increase the arteriovenous fistula (AVF) prevalence rate for hemodialysis patients, and is partnering with renal networks and other organizations to help meet this target. An AVF is the connection of a vein and an artery, usually in the forearm, to allow access to the vascular system for hemodialysis, a procedure that performs the functions of the kidneys in people whose kidneys have failed. The surgical creation of an AVF provides a long-lasting site through which blood can be removed and returned during hemodialysis.  If the vein and artery can’t be directly joined, then an arteriovenous graft (AVG) is needed for hemodialysis, to surgically connect an artery to a vein using a graft.

Physicians were ranked based on the ratio of AVF placements to AVG procedures in 2011, and Dr. Larson had the top ranking.
