A rare case of isolated right subclavian artery (RSCA) originating from the pulmonary artery in a newborn with d-transposition of the great arteries (D-TGA) caused differential cyanosis. Surgical reimplantation of the RSCA was successfully performed.
Area of Science:
- Cardiology
- Pediatric Surgery
- Vascular Surgery
Background:
- Aberrant origin of the subclavian artery (SCA) is a known congenital vascular anomaly.
- Complete isolation of the SCA is rare, particularly the right SCA (RSCA).
- Isolation of the RSCA in patients with d-transposition of the great arteries (D-TGA) is exceptionally infrequent.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
