[Repeated Myocardial Infarction due to Intraluminal Thrombus in a Coronary Aneurysm Suspected to be Caused by Vasculitis in a Young Male:Report of a Case].

Coronary artery aneurysms are rare and are often associated with atherosclerosis in adults and Kawasaki disease in children. Thromboembolism and rupture of the aneurysm are common complications associated with this condition. We report a case of coronary aneurysm resection and coronary artery bypass grafting (CABG) in a 36-year-old man with a history of recurrent acute myocardial infarction. There was no coronary aneurysms in first acute myocardial infarction. Histopathological examination of the resected coronary artery aneurysm wall revealed features of vasculitis, although the patient showed no episodes and physical findings of vasculitis. Coronary vasculitis can cause vascular endothelial cell injury and therefore requires careful follow-up.

Unexpected migration of a sternal pin: A word of caution.

BACKGROUND: Sternal pins are adjuncts used to enhance sternal stability after sternotomy, but only a few complications associated with them have been previously reported. MATERIAL, METHODS AND RESULTS: A 42-year-old woman underwent pulmonary valve replacement through re-sternotomy for pulmonary valve regurgitation after repaired tetralogy of Fallot. Because of severe sternal deformity, the sternum was refixed using a sternal pin in addition to sternal wires. However, postoperative computed tomography unexpectedly revealed migration of the sternal pin towards the right coronary artery, necessitating emergency surgical removal of the pin. DISCUSSION: Sternal pins may not adequately fit the deformed sternum, resulting in sternal pin-induced sternal injury. CONCLUSION: Sternal pins are considered useful for sternal stabilization after sternotomy, we should take special care in applying sternal pins to patients presented severe sternal deformity.

A Primary Pulmonary Meningioma That Grew Over 10 Years: A Surgical Case Report.

Primary pulmonary meningiomas (PPMs) are rare meningothelial proliferation that lacks characteristic imaging findings, making their distinction from other peripheral lung tumors challenging. Therefore, surgical resection is often performed for the diagnosis and treatment of PPM. Herein, we describe a surgical case of PPM that grew over 10 years. A 63-year-old woman was referred to our department due to right middle lobe lung tumor enlargement. No significant symptoms were observed. Chest computed tomography revealed a tumor in the middle lobe of the right lung. F-18 fluorodeoxyglucose positron emission tomography showed accumulation in the nodule; thus, lung cancer could not be ruled out. Therefore, the preoperative differential diagnosis was cStageIB lung cancer. A right middle lobectomy was performed, and a histopathology examination revealed meningioma. There were no primary lesions in the head and whole spine magnetic resonance imaging, thus, a final diagnosis of PPM was made. Cautious observation is required postoperatively due to the possibility of recurrence.

Impact of central nervous system metastasis after complete resection of lung adenocarcinomas harboring common EGFR mutation - A real-world database study in Japan: The CReGYT-01 EGFR study.

OBJECTIVES: To clarify the impact of central nervous system (CNS) metastasis on performance status (PS) at relapse, on subsequent treatment(s), and on survival of patients with lung adenocarcinoma harboring common epidermal growth factor receptor (EGFR) mutation. METHODS: We conducted the multicenter real-world database study for patients with radical resections for lung adenocarcinomas between 2015 and 2018 at 21 centers in Japan. EGFR mutational status was examined at each center. RESULTS: Of 4181 patients enrolled, 1431 underwent complete anatomical resection for lung adenocarcinoma harboring common EGFR mutations. Three-hundred-and-twenty patients experienced disease relapse, and 78 (24%) had CNS metastasis. CNS metastasis was significantly more frequent in patients with conventional adjuvant chemotherapy than those without (30% vs. 20%, P = 0.036). Adjuvant chemotherapy did not significantly improve relapse-free survival at any pathological stage (adjusted hazard ratio for stage IA2-3, IB, and II-III was 1.363, 1.287, and 1.004, respectively). CNS metastasis did not affect PS at relapse. Subsequent treatment, mainly consisting of EGFR-tyrosine kinase inhibitors (TKIs), could be equally given in patients with or without CNS metastasis (96% vs. 94%). Overall survival after relapse was equivalent between patients with and without CNS metastasis. CONCLUSION: The efficacy of conventional adjuvant chemotherapy may be limited in patients with lung adenocarcinoma harboring EGFR mutations. CNS metastasis is likely to be found in practice before deterioration in PS, and may have little negative impact on compliance with subsequent EGFR-TKIs and survival after relapse. In this era of adjuvant TKI therapy, further prospective observational studies are desirable to elucidate the optimal management of CNS metastasis.

Hybrid operation for infectious thoracic and abdominal aortic aneurysms complicated with Bacillus Calmette-Guérin therapy for bladder cancer: A case report.

RATIONAL: Bacillus Calmette-Guérin (BCG) intravesical instillation therapy is a widely used treatment for bladder cancer; however, an infectious aneurysm has been reported as a rare complication. PATIENT CONCERNS: A 76-year-old man who underwent BCG intravesical instillation therapy for bladder cancer presented with prolonged dull back pain for 3 months. DIAGNOSIS: Computed tomography (CT) revealed both thoracic and abdominal aortic aneurysms (AAAs). Follow-up CT at 4 weeks after the initial examination showed rapid enlargement of both aneurysms and typical findings of inflammation. Therefore, he was diagnosed with an impending rupture of infectious aneurysms. INTERVENTIONS: Although open surgical resection of both aneurysms and vascular reconstruction were ideal, these operations were considered highly invasive for the patient. Therefore, a hybrid operation consisting of simultaneous endovascular repair of the thoracic aneurysm and open surgery of the abdominal lesion was performed. OUTCOMES: BCG "Tokyo-172" strain was identified in the resected sample from the aneurysmal wall, and he continued to receive oral antituberculosis drugs for 6 months. No sign of recurrent infection was observed 1 year after the operation. LESSONS: A hybrid operation might be justified as an alternative to the conventional open surgical procedure, especially for patients with infectious aneurysms caused by weak pathogenic bacteria such as, the BCG mycobacteria.
