Analysis of a streamlined pathway for aortic surveillance for Turner syndrome in a single centre

The risk of aortic dissection (AoD) is increased in women with Turner syndrome (TS) but predicting those with this heightened risk is difficult. In response to this, we sought to create a pathway to monitor TS patients to improve efficiency and resource utilisation in our dedicated TS clinic, and to monitor more closely those women thought to be at increased risk of AoD.Our pathway was designed based on evidence derived from International Guidelines for the management of aortic disease in women with TS. Women were divided according to those with known risk factors for AoD, and those with no known risk factors. These groups were further subdivided into 4 pathways depending on ascending aortic size which in-turn determined the frequency of outpatient appointments and imaging.Out of the 168 patients included in the analysis, 7 have had ascending aorta replacements, all in the highest risk group. Of the remaining 4 patients in the highest risk groups: 1 dissected whilst awaiting planned aortic surgery, 1 is currently awaiting surgery, 1 has low body mass index, therefore, making her aorta proportionally larger but not necessitating surgery and one has declined surgery. No women changed pathways.The risk-stratified pathway safely allowed consolidation of resources to women perceived to be at highest risk of AoD (excluding pregnancy), supporting the efficacy of the pathway and allowing the diversion of resources to those most at risk of AoD.
