[Surgical treatment of aberrant subclavian artery]. / Khirurgicheskoe lechenie aberrantnoi podklyuchichnoi arterii.

OBJECTIVE: To determine the indications and optimal surgical treatment of aberrant subclavian artery. MATERIAL AND METHODS: There were 3 patients with aberrant subclavian artery with clinical manifestations such as dysphagia, shortness of breath, weight loss, cough and chest pain between 2005 and 2020. Right-and left-sided aberrant artery was observed in 2 and 1 case, respectively. Supraclavicular unilateral or bilateral access depended on the side of aberrant artery. Carotid-subclavian anastomosis was performed. RESULTS: All patients were discharged without any symptoms. CONCLUSION: Close location of aberrant subclavian artery to common carotid artery can disturb circulation in brain and upper limb. Abnormal discharge of subclavian artery can cause compression of nearby organs (esophagus, trachea). Abnormal vascular discharge does not always have clinical manifestations that do not require surgical correction. Only symptomatic patients are subjects to surgical correction of aberrant subclavian artery. Knowledge of variant anatomy of supra-aortic vessels can minimize the risk of complications.

The Efficacy of Resin Infiltrant and Casein Phosphopeptide-amorphous Calcium Fluoride Phosphate in Treatment of White Spot Lesions (Comparative Study).

BACKGROUND: White spot lesions (WSLs) are considered as the first sign of the progression of dental caries that can be reversed. Casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP) varnish can promote remineralization process of the demineralized tooth structure. Also, WSLs can be managed by using caries infiltrant (ICON), which infiltrates etched enamel surface of the WSLs. OBJECTIVES: The main aim was to evaluate and compare the efficacy of ICON versus CPP-ACFP varnish to treat WSLs in the same oral environments. MATERIALS AND METHODS: A total of 30 participants aged 20-40 years with at least two WSLs have participated in this trial. Split-mouth technique has been used in this trial where WSLs on the left side have been treated with ICON, whereas WSLs on the right side have been treated with CPP-ACFP varnish. Clinical evaluation using DIAGNOdent was carried out at baseline, 1 week, 1, 3, 6, and 12 months after application to determine the effectiveness of these materials in treating WSLs. RESULTS: Significant differences were observed between all follow-up DIAGNOdent scores compared to baseline readings of both ICON and CPP-ACFP (P = 0.000 for all comparisons). Statistically significant differences were observed between DIAGNOdent scores of ICON compared to CPP-ACFP at all follow-up intervals (P = 0.006, 0.008, 0.045, 0.036, and 0.000). CONCLUSION: Both ICON and CPP-ACFP were effective in the treatment of WSLs of smooth surfaces but the efficacy of CPP-ACFP was better than ICON.
