Utility of transmanubrial osteomuscular sparing approach and its modification in vascular surgery: a case series study of surgeries related to subclavian artery

Abstract

Abstract Background The operative field in subclavian vessel surgery is limited by thoracic inlet and outlet structures. Although endovascular therapy for the subclavian artery could be an option, open repair management is occasionally required in cases of large aneurysms, infectious vasculopathy, and trauma. The transmanubrial osteomuscular sparing approach, commonly used in thoracic surgery area to resect superior sulcus tumors, is a simple and safe procedure providing an excellent view of the operative field. Herein, we present three cases that underwent open repair of the subclavian artery using the transmanubrial osteomuscular sparing approach, and we also highlight the utility of the technique along with the procedural details. Case presentation Case 1: A 54-year-old man presented with a true aneurysm of the proximal portion of the right subclavian artery. The aneurysm measured 50 × 80 mm and compressed the right lung and trachea. We performed an aneurysm resection and a right subclavian artery reconstruction via the transmanubrial osteomuscular sparing approach under cardiopulmonary bypass support. Case 2: A 72-year-old man who presented with an abscess that formed around the left subclavian artery due to an unremoved guidewire during thoracic endovascular aortic repair for an aortic arch aneurysm in another hospital. After the antibiotics administration, debridement and axillary-axillary bypass were performed, and the guidewire was removed via a transmanubrial osteomuscular sparing approach with a use of cardiopulmonary bypass. Case 3: A 60-year-old man presented with misplacement of an indwelling dialysis catheter inserted for acute renal failure and hyperkalemia. The catheter was placed through the right neck, but had penetrated the right internal jugular vein and was misplaced from the right subclavian artery into the proximal aortic arch. Emergently, we removed the catheter using the transmanubrial osteomuscular sparing approach. Conclusions The transmanubrial osteomuscular sparing approach to the subclavian artery provides an excellent view and a wide surgical field, even in different pathological situations. This is a simple, safe, and highly useful procedure and could be the standard approach for subclavian artery surgeries.
