Subclavian Artery
Palliation first when the child is very small, has hypoplastic pulmonary arteries or anomalous coronaries: a Blalock-Taussig shunt (subclavian artery to pulmonary artery) to raise pulmonary blood flow, with later complete repair.
What our notes say
- Palliation first when the child is very small, has hypoplastic pulmonary arteries or anomalous coronaries: a Blalock-Taussig shunt (subclavian artery to pulmonary artery) to raise pulmonary blood flow, with later complete repair.

- In coarctation of the aorta distal to the subclavian artery origin, blood is diverted through the subclavian artery (Aponeurosis — Anatomy Question Bank)
- The pharyngeal branches, the cardiac branches, and the right recurrent laryngeal nerve (in the neck on the right, hooking round the right subclavian artery) also arise in the neck or at its base. (MBChB/BDS EXAMINATION QUESTIONS AND MARKING SCHEME)
- Narrowing of the aorta — most commonly just DISTAL to left subclavian artery (juxtaductal) (🫀 MISSING TOPICS — ULTRA DEEP NOTES)
- Narrowing of aorta, usually juxtaductal (distal to left subclavian artery) (CARDIOVASCULAR PATHOLOGY)
- Recurrent laryngeal nerve: right loops under subclavian artery; left loops under aortic arch → larynx below vocal cords and all intrinsic laryngeal muscles except cricothyroid (Master First-Year Anatomy: Must-Know Essays & Key Concepts)
