Graft Strategy for Coronary Artery Bypass Grafting in Patients with Severe Left Ventricular Dysfunction

BACKGROUND@#Optimal graft selection for coronary artery bypass grafting (CABG) in patients with severe left ventricular (LV) dysfunction remains debatable. We report an analysis of our experiences of isolated CABG in patients with severe LV dysfunction and the impact of graft strategy on long-term outcomes.@*METHODS@#We analyzed 209 patients with severe LV dysfunction (ejection fraction [EF] <30%) who underwent primary isolated CABG. Of these, 169 were revascularized with a bilateral internal thoracic arterial (ITA) graft (BITA group) and 40 were revascularized with a single ITA graft (SITA group). The mean follow-up duration was 22±32 months.@*RESULTS@#There were 18 early deaths (8.6%). Overall survival at 5 years was 66.7%. The rate of freedom from cardiac-related death at 5 years was 74.1%, and was significantly higher in patients who underwent off-pump CABG (p=0.005) and in the BITA group (p=0.023). Multivariate analysis demonstrated that old age (hazard ratio [HR], 2.548; 95% confidence interval [CI], 1.134–5.762; p=0.024), off-pump CABG (HR, 0.245; 95% CI, 0.090–0.661; p=0.006), and BITA grafts (HR, 0.333; 95% CI, 0.146–0.757; p=0.009) were correlated with cardiac mortality.@*CONCLUSION@#CABG in patients with severe LV dysfunction (EF < 30%) showed reasonable long-term outcomes. The rate of freedom from cardiac-related death was significantly higher in patients who underwent off-pump CABG and in the BITA group. Off-pump BITA grafting strategies can be accepted as a viable primary option in patients with severe LV dysfunction if performed by an experienced surgeon.

Thoracic Splenosis after Splenic and Diaphragmatic Injury

Thoracic splenosis is a rare disease that develops as a result of autotransplantation of splenic tissue into the thoracic cavity following splenic and diaphragmatic injury. We report the case of a 53-year-old man with a chief complaint of heartburn and cough. He had a history of traumatic diaphragmatic rupture treated with surgical repair and splenectomy 15 years ago. Imaging studies revealed a paraesophageal mass, and surgical resection was performed considering the possibility of Castleman disease or an esophageal submucosal tumor. Pathologic results showed findings of normal splenic tissue. The patient was discharged on postoperative day 5 without any complications.

Sibutramine (Reductil(R))-Induced Cutaneous Leukocytoclastic Vasculitis: A Case Report

A 24-year old woman presented with hemorrhagic vesicles on her legs. She had taken sibutramine (Reductil(R), Abbott Labs., Seoul, South Korea) for 3 months and developed skin lesions the week before. A skin biopsy showed leukocytoclastic vasculitis with conspicuous eosinophilic infiltration of the tissue. These lesions showed improvement after discontinuation of sibutramine. However, 3 months later the skin lesions recurred on other sites on the lower extremities when the patient was rechallenged with the same drug for 2 weeks. Herein, we report the first case of necrotizing vasculitis induced by sibutramine.

Aplasia Cutis Congenita of the Scalp Accompanied by Limb Hypoplasia: Adamson-Oliver Syndrome / 대한피부과학회지

Aplasia cutis congenita (ACC) is an uncommon condition which is characterized by congenital, localized or widespread absence of skin or scar formation. Lesions can be multiple and may occur on any body surface, although they are mostly seen on the scalp as a solitary lesion. ACC is most often a benign isolated defect; but it can be associated with other physical anomalies or malformation syndromes. Adams-Oliver syndrome is a distinct subtype in which distal limb reduction is found in association with a solitary scalp defect. There is no single underlying cause of ACC; it may reflect a disruption of intrauterine skin development. A 25 day-old boy was referred to our clinic with a thick hemorrhagic crust, and a surrounding hairless atrophic scar on the midline over the skull vertex. He also had hypoplasia of the left 2nd to 5th toes since birth. The rest of the physical examination as well as an ultrasound examination of the brain were normal. Herein we report a rare case of ACC of the scalp accompanied by distal limb hypoplasia, Adamson-Oliver syndrome.

A Case of Congenital Dacryocystocele

A 6-day-old infant presented with a deeply bluish cystic mass below the right medial canthus. She had been born healthy. Under the impression of a hemangioma brain computed tomography was conducted. As a result, a diagnosis of congenital dacryocystocele was made. We present this case to show that it is important for a dermatologist to correctly identify congenital dacryocystoceles and appropriately refer the infant to a pediatric ophthalmologist prior to performing invasive measures.
