Abstract Background Vascular anomalies of the Aortic arch can cause respiratory symptoms in children due to tracheal compression. Treatment consists of division of the vascular rings, nevertheless data regarding mid- term results is scarce. The purpose of this study was to evaluate clinical results of vascular ring surgery. Methods Between2007–2014, 85 children underwent vascular ring surgery. 51 had Double Aortic Arch (DAA, 60%), 31 Right Arch with Aberrant Subclavian Artery (RAA & ALSA, 36.5%) and 3 had RAA, mirror image branching & left ductus arteriosus (3.5%). Mean age and weight at operation were 12.4±13months and 8.6±4.1 kg respectively. Mid-term follow-up included clinical follow up by a pulmonologist (38 patients, 44.7%) and a telephone questionnaire (71 patients, 83%) performed 57±25.7 months after surgery. Results In most patients, symptomatic relief occurred in less than 6 months (table 1). Mid –term follow up revealed that although most parents described a significant improvement in their child's respiratory symptoms (95%), a significant number of patients described some residual respiratory symptoms (table 2). We did not find any significant association between age at surgery (under 6 month), or vascular ring anatomy (DAA vs. RAA&ASA) and the presence of residual symptoms at follow up Conclusions Surgical division of vascular rings results in a significant clinical improvement within one year, nevertheless many patients remain symptomatic to some degree. We found no association between the age at surgery or anatomic variant to the presence of symptoms in mid- term follow up. Further evaluation whether a more aggressive surgical approach is warranted in order to decrease the incidence long-term symptoms. Funding Acknowledgement Type of funding source: None

McAllister, Richard M., and M. Harold Laughlin.Short-term exercise training alters responses of porcine femoral and brachial arteries. J. Appl. Physiol. 82(5): 1438–1444, 1997.—The primary purpose of this study was to test the hypothesis that short-term exercise training enhances endothelium-dependent relaxation of porcine femoral and brachial arteries. Miniature swine ran on a treadmill for 1 h at 3.5 miles/h, twice daily, for 7 consecutive days (Trn; n = 8). Compared with sedentary controls (Sed; n = 7), Trn swine exhibited increased skeletal muscle citrate synthase activity ( P < 0.05). Vascular rings ∼3 mm in axial length were prepared from segments of femoral and brachial arteries, and responses to vasoactive agents were determined in vitro. Sensitivity to bradykinin (BK) was enhanced in brachial vascular rings from Trn swine compared with those from Sed swine, as indicated by lower concentration of vasorelaxing agent eliciting 50% of maximal response values [Sed, 8.63 ± 0.09 (−log M); Trn, 9.07 ± 0.13; P < 0.05]. This difference between groups was preserved in brachial rings in which formation of nitric oxide and vasodilator prostaglandins were inhibited [Sed, 8.57 ± 0.17 (−log M); Trn, 8.97 ± 0.13; P < 0.05]. Sensitivity to BK was not different between Sed and Trn in femoral arterial rings. Relaxation responses to the calcium ionophore A-23187 and sodium nitroprusside were not altered with training. Femoral and brachial arterial rings from Trn swine, compared with those from Sed swine, exhibited augmented vasocontraction across a range of concentrations and increased sensitivity to norepinephrine (all P < 0.05). These findings indicate that responses of porcine femoral and brachial arteries change in response to short-term training. Together with findings from previous studies involving longer term training, our data suggest that vascular adaptations may differ at different time points during long-term endurance exercise training.
