Surgically challenging inflammatory myofibroblastic tumor: A rare neoplasm of lung.

Inflammatory myofibroblastic tumor is considered one of the rarest benign tumors constituting 0.7% of all lung neoplasms. It was first described in 1939. We report a case of a 10-year-old child who presented with recurrent cough and fever. Chest radiography and computed tomography demonstrated complete involvement of right lung by the tumor. The tumor along with the affected lung was meticulously dissected from the surrounding structures and was delivered outside. The histopathology of the specimen revealed it to be inflammatory fibroblastoma.

"Y" incision and rectangular patch enlargement of aortic annulus and valve reconstruction with autologous pericardium in congenital aortic stenosis.

Surgical aortic valve replacement in children who have undergone prior balloon or surgical valvuloplasty or both is a formidable challenge. The aortic annulus is small, there is no ideal prosthesis and lifelong anticoagulation is highly undesirable. A "Y" incision and rectangular patch enlargement of the aortic annulus introduced by Dr. Bo Yang in 2020 combined with aortic valve reconstruction introduced by Dr. Shigeyuki Ozaki in 2011, is feasible, as described in this case.

Emergency valve preserving ascending aorta replacement following iatrogenic right coronary artery dissection: A life-saving procedure.

Iatrogenic aortocoronary dissection is a rare but potentially fatal complication of coronary catheterizations. Although the incidence is comparatively low, dissection often leads to procedure failure with increased risk of myocardial infarction and death. Iatrogenic aortocoronary dissection is principally caused by disruption of intima at the ostia of the right or left coronary artery during interventional procedures and appears as luminal filling defects, the persistence of contrast or intimal tear outside the coronary lumen. We present a case of right coronary artery dissection leading to type-A aortic dissection suffered during diagnostic coronary catheterization. This required emergency supracoronary replacement of the ascending aorta with an aortic interposition tube graft and venous grafts to coronary arteries.
