Aberrant subclavian artery (ASA) is the most frequently encountered congenital anomaly of aortic arch. The ASA aneurysms are rare but potentially lethal disease, it has been recognized that the presence of an aneurysm of an ASA itself is an indication for surgery. We experienced 4 cases with ASA during the past 23 years. ⋯ Three patients had a right-sided aortic arch. Among the 4 patients, only 1 underwent total arch replacement, but the other 3 patients could be followed conservatively for 1, 7 and 23 years, respectively. We reviewed the problem of the diagnosis and treatment of the ASA including surgical indication.

Case Reports
[Stenting for postoperative airway stenosis due to traumatic tracheobronchial rupture].
A 43-year-old man underwent repair for the broken trachea, left main bronchus and right main brouchus due to trauma. Twenty-seven months after the initial surgery, he developed dyspnea and required ventilatory support. Computed tomography showed severe stenosis of the left main bronchus, tracheomalasia and bronchomalasia of right main bronchus. ⋯ SEMS developed granulatory and cicatricial stenosis of the airway, which caused severe dyspnea. Replacement of SEMS with Dumon stents was successfully done and dyspnea was disappeared. A silicon stent should be used for treating postreconstructive airway stenosis including tracheobronchomalasia.

Case Reports
[Total removal of infected pacemaker lead with cardiopulmonary bypass; report of a case].
The incidence of infection after pacemaker implant has been reported to occur rarely but it's one of the severe complication. Pacemaker lead sometimes imbedded in the right atrial and ventricular wall, and it seemed to be difficult to remove the pacemaker lead by closed techniques. ⋯ Following antibiotic therapy, the lead was successfully removed by cardiotomy on cardiopulmonary bypass. Total removal with cardiopulmonary bypass would be recommended.
