Background: Kommerell's diverticulum (KD) with aberrant left subclavian artery is a rare congenital deformity and also has very little research literature about it (35% of case study). There are three types of aortic arch diverticulum. Even literature concerning the treatment options are limited.
Case summary: We present a case report of a 50-year-old male with KD in the right aortic arch with aberrant left subclavian artery. We conducted a total endovascular repair procedure, which is innovative and will spread more light in the medical world. Our patient has no past medical history and is a non-smoker and non-alcoholic. Patient presented with shortness of breath, chest pain and dizziness for six months. Blood tests were done and computerized tomography (CT) angiogram of the chest confirmed the diagnosis, illustrating showed a 3.9 cm KD. On Day 1, the CT angiogram showed mild dilatation of the thoracic aorta, adjacent esophagus, trachea was compressed and displaced. Surgery was planned as the treatment modality. Carotid-Subclavian artery bypass and endovascular aortic repair was conducted. We used prolene 5-0 C1 sutures to precisely anastomose a 6-mm Dacron graft to the left subclavian artery. Haemostasis was secured and wounds were closed. Protamine was administered and patient was shifted to intensive care unit. Post-operative, patient responded favorably and was discharged. Regular follow-up is done.
Conclusion: The procedure we performed is novel. This will help the cardio-thoracic surgeons a better insight about the full procedures we conducted, thereby bringing more light and better treatment options in managing KD with aberrant subclavian artery.
