Introduction: It is difficult to manage that pruritus complicated with jaundice, for invalidity of almost all antihistamines. Recently, effects of paroxetine for pruritus are reported, but the report to invalid cases of paroxetine is rare. We report a case treated effectively with mirtazapine for pruritus of the paroxetine invalid. Case report: A 56-years old woman was diagnosed cancer of head of pancreas and peritoneal dissemination.After stenting by a plastic stent for obstructive jaundice in previous hospital, she came to our hospital. But, her total bilirubin (T-bil) were very high (9.9 mg/dl), and she was suffering from systemic pruritus. The NRS (numerical rating scale) score for pruritus was 9-10. Though she was prescribed an antihistamine in previous hospital, it was invalid. We had changed it to paroxetine, but pruritus were protraction two weeks later. After changing it to mirtazapine, the pruritus became NRS 1 on the next day, and recurrence was not seen subsequently. Conclusion: For pruritus of the paroxetine invalid, mirtazapine is important as one of the choices.

Entrapment of an intravascular ultrasonography (IVUS) catheter is an infrequent but serious complication associated with percutaneous coronary intervention (PCI). We report a case of successful surgical treatment of an IVUS catheter entrapped in a coronary stent after PCI. An-80-year-old man was admitted to a hospital with sudden anterior chest pain. He underwent PCI to left circumflex branch (Cx) and left anterior descending artery (LAD), followed by IVUS to ascertain stent expansion of the LAD stent. The IVUS catheter became entangled in the stent and could not be withdrawn from the outside. The patient was transferred to our hospital for its surgical removal. For the emergent surgery, we opened the stent region in the LAD and directly removed the IVUS catheter with the twisted stent. The opened place in the LAD was directly closed. Additional coronary bypass grafting involving two vessels was performed. The postoperative course was uneventful with no graft occlusion.

Aortic dissection presents with acute chest or back pain. However, it can be asymptomatic in the acute phase with delayed symptomatic presentation or incidental diagnosis upon chest imaging. We report a case of acute type B aortic dissection subsequent to chronic type A aortic dissection which was difficult to distinguish from acute type A aortic dissection. A 45-year-old man was admitted to a hospital with sudden back pain. An enhanced chest CT revealed a suspected acute type A aortic dissection. The patient was transferred to our hospital and we performed an emergent total arch replacement. Intraoperative findings showed that there were two entries at the origin of the brachiocephalic artery and the left subclavian artery. The ascending aorta presented wall thickening but the descending aorta did not present wall thickening. Histopathologically, the adventitia was obviously thickened with dissection findings in the tunica media. Thus it was diagnosed as acute type B aortic dissection subsequent to chronic type A aortic dissection. Great caution should be taken in asymptomatic chronic aortic dissection.
