Graft Replacement for Adult Aortic Coarctation

: Case 1:a 47-year-old woman who complained of sweating, finger tremor, and chest pain was diagnosed with coarctation of the aorta and hyperthyroidism. She had been diagnosed with hypertension at 25 years of age but had not undergone further examination. Graft replacement was performed without cardiopulmonary or temporary bypass. Case 2:a 30-year-old woman was diagnosed with coarctation during infertility treatment. Although health screening had revealed hypertension 8 years previously, no further assessment took place. She underwent graft replacement with partial cardiopulmonary bypass. In both cases, we conducted a clamp test to decide whether cardiopulmonary or partial bypass was necessary for graft replacement. Blood pressure discrepancy between upper and lower extremities disappeared immediately after surgery, and no ischemic complications were observed. Hypertension in young adults should prompt further scrutiny for anatomical disorders such as coarctation. A clamp test is considered helpful regarding the surgical approach to graft replacement for coarctation.
