Iatrogenic Left Internal Mammary Artery to Great Cardiac Vein Anastomosis Treated With Coil Embolization

Inadvertent left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomosis is a rare complication of coronary artery bypass graft surgery. Patients with iatrogenic aortocoronary fistula (ACF) were usually treated surgical repair, percutaneous embolic occlusion with coil or balloon. We report a case of iatrogenic LIMA to GCV anastomosis successfully treated with coil embolization and protected left main coronary intervention through the percutaneous transfemoral approach.

Prevalence and Patterns of Left Ventricular Dysfunction in Patients with Pheochromocytoma

BACKGROUND: Excessive catecholamine release in pheochromocytoma is known to cause transient reversible left ventricular (LV) dysfunction, such as in the case of pheochromocytoma-associated catecholamine cardiomyopathy. We investigated patterns of clinical presentation and incidence of LV dysfunction in patients with pheochromocytoma. METHODS: From January 2004 to April 2011, consecutive patients with pheochromocytoma were retrospectively studied with clinical symptoms, serum catecholamine profiles, and radiologic findings. Patterns of electrocardiography and echocardiography were also analyzed. RESULTS: During the study period, a total of 36 patients (21 males, 49.8 +/- 15.8 years, range 14-81 years) with pheochromocytoma were included. In the electrocardiographic examinations, normal findings were the most common findings (19, 52.8%). LV hypertrophy in 12 cases (33.3%), sinus tachycardia in 3 (8.3%), ischemic pattern in 1 (2.8%) and supraventricular tachycardia in 1 (2.8%). Echocardiographic exam was done in 29 patients (80.6%). Eighteen patients (62.1%) showed normal finding, 8 (27.6%) revealed concentric LV hypertrophy with normal LV systolic function, and 3 (10.3%) demonstrate LV systolic dysfunction (LV ejection fraction < 50%). Three showed transient LV dysfunction (2 with inverted Takotsubo-type cardiomyopathy and 1 with a diffuse hypokinesia pattern). Common presenting symptoms in the 3 cases were new onset chest discomfort and dyspnea which were not common in the other patients. Their echocardiographic abnormalities were normalized with conventional treatment within 3 days. CONCLUSION: Out of total 36 patients with pheochromocytoma, 3 showed transient LV systolic dysfunction (catecholamine cardiomyopathy). Pheochromocytoma should be included as one of possible causes of transient LV systolic dysfunction.

A Case with Upper Extremity Deep Vein Thrombosis after in vitro Fertilization

Deep vein thrombosis (DVT) is a predisposing condition of pulmonary embolism which can be fatal. Usually, DVT is found in the lower extremities. However, DVT can be occurred in the upper extremities. The usual predisposing conditions of the upper extremity DVT include insertion of central venous catheters and pacemaker wires. Here, we report a case of upper extremity DVT after in vitro fertilization and embryo transfer. The patient was successfully controlled with subcutaneous administration of low molecular weight heparin.

A Case of Acute ST-Segment Elevation Myocardial Infarction Mimicking Stress Induced Cardiomyopathy; Demonstration of Typical Echocardiographic Finding Correlated with Unusual Distribution of Left Anterior Descending Coronary Artery

Stress-induced cardiomyopathy (SCMP) is diagnosed in 1-2% of patients presenting with symptoms suggestive of acute coronary syndrome. Because of sharing many common clinical features with SCMP, acute ST-segment elevation myocardial infarction (STEMI) can be misdiagnosed as SCMP. However, it can be associated with fatal outcome of the patient. Also, diagnosis of SCMP seems to be always challenging to clinicians, especially in the decision of taking coronary angiography which is still invasive and even risky. Here, we present a case with acute STEMI mimicking SCMP as a result of anatomical variation of coronary circulation. In this patient, prompt and early coronary angiography and stent implantation was very helpful.

Development of Total Body Irradiation Program / 의학물리

In total body irradiation (TBI) for leukemia, we have a two methode. One is a AP (anterior-posterior) method and the other is a Lateral methode. Our hospital used lateral methode. TBI must consider about body contour, because of homogeneous dose distribution. For compensation about irregular body contour, we use compensator. For TBI treatment, we must be considered, accurate manufacture of compensator and accurate calculation of dose. We developed the automatic program for TBI. This program accomplished for compensator design and dose calculation for irregular body. This program was developed for uses to use in a windows environment using the IDL language. In this program, it use energy data for each energy: TMR, output factor, inverse square law, spoiler, field size factor. This program reduces the error to happen due to the manual. As a development of program, we could decrease the time of treatment plan and care the patient accurately.
