A Case of Eisenmenger Syndrome with Brain Abscess

The Eisenmenger syndrome is characterized by severe irreversible pulmonary hypertension and right-to-left shunting of blood through the pulmonary-systemic communication. The resultant right-to-left shunt leads to clinical cyanosis and secondary manifestations of chronic hypoxemia. Clinical features include dyspnea on exertion, fatigue, palpitation, hemoptysis, syncope, chest pain and predisposition to brain abscess and cerebrovascular accident. Brain abscess is a serious complication of cyanotic congenital heart disease and major cause of death. We report a patient with Eisenmenger syndrome in whom the presence of right-to-left shunt and paradoxical embolism appears to be critical for the development of brain abscess.

Retained Sleeve Marker Ring of a Stent Delivery System in the Coronary Artery Following Coronary Artery Stenting

There are many various complications associated with coronary artery stenting, in cluding thrombotic and hemorrhagic complications, in-stent restenosis, side branch occlusion, stent embolization. The retention of equipment components is the uncommon, unexpected and often problematic situations that can arise requiring ingenuity, skill, and creativity. We reports on a patient in whom an sleeve marker ring of a stent balloon catheter retained within the lumen of the coronary artery following coronary stenting. The sleeve marker ring was extracted by dilatation and withdrawal of balloon catheter which readvanced over a guidewire positioned in the center of ring.

Two Cases of Emphysematous Pyelonephritis in a Diabetic Patients: Experience of Successful Management by Medical Treatment / 대한신장학회잡지

Emphysematous pyelonephritis is an uncommon, but life-threatening necrotizing inflammation of renal parenchyme and perinephric tissue by gas-forming organisms. This disease is encountered mainly in patients with uncontrolled diabetes mellitus and/or urinary tract obstruction etc. Though the pathogenesis of this diseases is still poorly understood, radiographic demonstration of gas shadow in renal parenchyme and peri-nephric tissue establishes the diagnosis of emphysematous pyelonephritis. The identification of this finding has been believed to consider incision and drainage or nephrectomy in addition to medical treatment, because of high mortality rate of this disease in spite of vigorous medical management. We report two cases of emphysematous pyelonephritis complicated in 62-year-old female and 48- year-old male patients with diabetes mellitus. Nephrectomies were not performed because of bilateral emphysematous pyelonephritis in one patient and of refusal of nephrectomy by the other patient. But patients were recovered completely on medical management.
