Spontaneous Disruption of Mycotic Aneurysm Involving Innominate Artery

We report a case of ruptured mycotic aneurysm involving innominate artery requiring an urgent surgical treatment. A 62-yr-old woman presented with fever and dyspnea. Previously, she was diagnosed with colon cancer and received right hemicolectomy and one cycle of adjuvant chemotherapy. On echocardiogram, pericardial effusion was noted and emergency pericardiocentesis was performed. CT scan revealed aortic aneurysm involving ascending aorta and innominate artery, and thrombi surrounding those structures. Patch repair of the defect in the ascending aorta and ringed Goretex graft to bypass the innominate and ascending aorta were performed. We believe that this is the first case of ruptured mycotic aneurysm involving innominate artery.

Tick Bites / 대한피부과학회지

Tick bites are dermatoses not commonly encountered in Korea. Identification of causative ticks as well as recognition of clinical signs and histopathologic findings are important in making a diagnosis in tick-related dermatoses. Hard ticks which belong to the Family Ixodidae are responsible for most tick-related diseases. Since the first human case of tick bite in Korea was reported in 1982, seventeen cases have been reported up to the present. All the inflicted ticks belonged to the genus Ixodes except a case by Haemaphysalis flava. Among 16 ticks, collected from 16 cases of tick bites caused by the genus Ixodes, nine I. nipponenses, an I. ovatus and I. persulcatus were identified. Recently we experienced 8 cases of tick bites, 6 of them were caused by the genus Ixodes including 4 I. nipponenses. One of them, whose essential complaint was fever and chills, showed the clinical course of tick bite pyrexia which had not been reported in Korea. The clinical and epidemiological findings of tick bites reported in Korea were reviewed, including these 8 cases.
