Creating hemodialysis autogenous access in children and adolescents.

OBJECTIVE: End-stage renal disease (ESRD) in childhood and adolescence is rare, with relatively few published reports of pediatric ESRD vascular access. This study analyzes a 10-year experience creating arteriovenous fistulas (AVFs) in children and adolescents. Our goal is to review our strategy for creating functional autogenous vascular access in younger patients and report our results. METHODS: We retrospectively reviewed data and outcomes for consecutive vascular access patients aged ≤19 years during a 10-year period. Each patient had preoperative vascular ultrasound mapping by the operating surgeon in addition to physical examination. A distal forearm radiocephalic AVF was the first access choice when feasible, and a proximal radial artery inflow AVF was the next option. Demographic data, inflow artery, venous outflow target, and required transposition vs direct AVFs were variables included in the analysis. Primary and cumulative patency were calculated by Kaplan-Meier analysis. RESULTS: Thirty-seven AVFs were created in 35 patients. No grafts were used. Ages were 6 to 19 years (mean, 15 years), and 20 were male. Causes of ESRD included glomerular disease (n = 18) and urinary obstruction or reflux (n = 7), among others. Three had previous AVFs, and 10 were obese. The proximal radial artery supplied AVF inflow in 25 patients and the brachial artery in only seven. Eleven individuals required a transposition and one a vein translocation to the contralateral arm. No patients developed hand ischemia, although two later required banding procedures for high flow. Eleven patients had successful transplants. A single patient died, unrelated to the vascular access. Five AVFs failed. Of these, two had new successful AVFs created, two regained renal function, one was transplanted, and one declined other procedures. Primary and cumulative patency rates were 75% and 85% at 12 months, 70% and 85% at 24 months, and 51% and 85% at 36 months, respectively. Median follow-up was 16 months. CONCLUSIONS: Creating an AVF for hemodialysis is a successful vascular access strategy for pediatric and adolescent patients. Proximal radial artery AVFs provided safe and functional access when a distal AVF was not feasible. Cumulative AVF patency was 85% at 36 months.

Vascular Surgery Training Positions and Applicant 10-Year Trends with Consideration for Further Expansion.

BACKGROUND: There is a significant shortage of vascular surgeons in the United States and projections for these practicing surgical specialists continue to worsen. Annual appraisal of our workforce recruitment and growth is imperative. MATERIALS AND METHODS: Retrospective data were analyzed using the National Resident Matching Program from 2012-2022 applicant appointment years (specialty code for vascular surgery 450). Simple linear trend analysis was performed for the number of positions available and the number of applicants, stratified by fellowship or residency. RESULTS: Over the 10-year study period, the total vascular surgery trainee positions expanded from 161 to 202. Integrated residency positions increased (41 positions in 2012 vs. 84 in 2022) while available fellowship positions remained stagnant (120 in 2012 vs. 118 in 2022). Total applicants rose as well, from 213 to 311. In 2022, unmatched applicants have increased for both paradigms (25 fellowship and 84 residency applicants) and 100% of programs filled. On average, the number of residency positions offered increased by 4 each year (P < 0.0001) and the number of fellowship positions increased by 0.5 each year (P = 0.1617). The number of integrated residency applicants increased by approximately 9 per year (P = 0.001), while the number of fellowships applicants increased by approximately 1.5 per year (P = 0.121). CONCLUSIONS: Applicants for both vascular tracks have increased since 2012 indicating successful recruitment; however, all 2022 programs filled, leaving many applicants unmatched. Residency positions have continued to expand while fellowship positions have not. With the demonstrated surge among applicants, the disproportionate lack of increasing training positions, and the existing shortage of vascular surgeons, there is an urgency to meet the increasing demand. A concerted effort should be made toward adding additional residency and fellowship positions where feasible.
