Objective: To report prenatal management and prognosis of a small series of ARSA (Aberrant Right Subclavian Artery) cases which were detected in the second trimester exam. Method: Computer based maternal-fetal medicine database of hospital was reviewed. Total 11 cases with ARSAfrom the 1859 singleton low risk pregnancies were identified. We reviewed medical records about diagnostic tests, pregnancy follow-up, delivery and neonatal exams. Results: Median maternal age of cases with isolated ARSA was 32 years old. Median gestational age at ultrasound scan was 21 weeks. All cases were isolated. All cases regretted invasive genetic diagnostic tests. Cell-free DNA (cell free DNA) tests were low risk in 7 of 11 casesPregnancy courses were uneventful in all cases and resulted in term uncomplicated delivery. No pathological finding was encountered in the neonatal examination. Conclusion: Prognosis is good in case of isolated ARSA diagnosis. Presence of ARSA is not only a marker for common trisomies also, it should be accepted as a caution for the conotruncal abnormalities of heart and 22q11.2 microdeletion. Cell free DNA test (Including 22q11.2 microdeletation) may an option for the who avoid invasive genetic test in case of positive ARSA, visualised thymus, optimally evaluated central nervous system and great vessels of heart.

The persistent sciatic artery is the continuation of the axial artery in fetal life and connects internal iliac arteries to popliteotibial vessels. It is a rare arterial variation. Although persistent sciatic artery is rare, atherosclerotic stenosis or aneurysm can be seen. If aneurysm is detected, treatment with interventional or surgical methods should be considered in order to prevent the risk of embolization or rupture. In this case report, we present a 33-year-old female patient with severe ischemic lesions on her feet who had femoral artery originated from internal iliac artery together with aberrant right subclavian artery and our treatment strategy.

Aberrant right subclavian artery is the most common congenital anomaly of the aortic arc. This situation which is usually asymptomatic, has to be corrected surgically if it becomes symptomatic. Since the surgical approach and method differs from patient to patient, a well made management should have done in order to get positive results. We find suitable to share this case to remind this relatively common anomaly and to make our surgical method as a guide for our colleagues. [ABSTRACT FROM AUTHOR]
