We report two hemodialysis patients who underwent cardiac surgery and unremitting exertional dyspnea and intradialytic hypotension despite improved leftheart function. In case 1, a 74-year-old man demonstrated an AVF flow of 2.91 l/min with a resistance index of 0.47. In case 2, a 74-year-old man had an AVF flow of 3.84 l/min and resistance index of 0.46. Both patients underwent surgical closure of the high-flow AVF. Following intervention, estimated pulmonary artery systolic pressure decreased from 55 to 25 mmHg in case 1 and from 35 to 25 mmHg in case 2. In both cases, patients became hemodynamically stable during dialysis sessions without need for vasopressors. These outcomes underscore that persistent PH after cardiac surgery in dialysis patients may be attributable to excessive AVF flow, which is a potentially manageable factor. Quantitative flow measurement (Qa) and the Qa/cardiac output ratio should be incorporated into routine evaluation, and timely intervention should be considered. Our experience highlights the clinical importance of recognizing high-flow access as a treatable cause of post-cardiac surgery PH.</p>","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

Although conservative management is usually the initial approach, persistent high-output chylous effusion may require surgical intervention, for which accurate identification of the leakage site is important. We describe two cases of refractory postoperative chylothorax following aortic surgery, in which surgical management was guided by intranodal lipiodol lymphangiography combined with computed tomography (CT). The first patient developed chylothorax after descending aortic replacement via left thoracotomy for chronic Stanford type B aortic dissection. Despite fasting, total parenteral nutrition, and octreotide administration, chylous drainage persisted. Lymphatic imaging suggested a localized leak adjacent to the distal anastomosis of the descending aortic graft, and direct local ligation was performed. The second patient developed chylothorax after total aortic arch replacement for a distal arch aneurysm. Imaging demonstrated chyle leakage from the dorsal aspect of the arch graft, where local repair was considered difficult;therefore, thoracoscopic thoracic duct ligation via a right-sided approach was selected. In both cases, chylothorax resolved promptly after reoperation without recurrence.
