Embarazo abdominal calcificado con 44 años de evolución / Calcified abdominal pregnancy with 44 years of evolution

Lithopedion (litho = piedra, pedion = niño), es el término utilizado para describir un feto intrabdominal calcificado. Es un evento raro, con aproximadamente 300 casos descritos en la literatura internacional. Este artículo trata del caso de una mujer de 84 años con dolor abdominal, donde se evidenció en el examen físico, una masa abdominal de consistencia pétrea, con dimensiones de 23 cm de altura y 32 cm de longitud. El examen radiológico del abdomen reveló la presencia de imagen de densidad ósea, sugiriendo la existencia de un feto abdominal calcificado. La tomografía computarizada confirmó tratarse de un litoquelifopedion de 29-30 semanas, con aproximadamente 44 años de evolución.

Lithopedion (litho = stone, pedion = child) is the term used to describe an intra-abdominal calcified fetus. In the international literature, about 300 cases were described. In this case, an 84-year old woman was admitted with abdominal pain and the abdominal physical examination showed a mass with hard consistency with 23 cm height and 32 cm width. The abdominal x-ray examination showed the presence of bone density image suggesting an intra-abdominal calcified fetus. The computer tomography confirmed that it was a litoquelifopedion of 29-30 weeks of pregnancy and with about 44 years of evolution.

Cardiac tamponade in an infant during contrast infusion through central venous catheter for chest computed tomography / Tamponamento cardíaco durante infusão de contraste em acesso venoso central para realização de tomografia computadorizada de tórax em lactente

Complications from central venous catheterization include infectious conditions, pneumothorax, hemothorax and venous thrombosis. Pericardial effusion with cardiac tamponade hardly occurs, and in infants is generally caused by umbilical catheterization. The authors describe the case of cardiac tamponade occurred in an infant during chest computed tomography with contrast infusion through a central venous catheter inserted into the right internal jugular vein.

Modificações eletrovetorcardiográficas após ablaçäo septal percutânea na cardiomiopatia hipertrófica obstrutiva e possíveis causas anatômicas / Vector electrocardiographic alterations after percutaneous septal ablation in obstructive hypertrophic cardiomyopathy. Possible anatomic causes

OBJECTIVE - Analyze the dromotropic disturbances (vector-electrocardiographic), and the possible anatomic causes, provoked by selective alcohol injection in the septal branch, for percutaneous treatment, of obstructive hypertrophic cardiomyopathy. METHODS - Ten patients with a mean age of 52.7 years underwent percutaneous septal ablation (PTSA) from october 1998; all in functional class III/IV). Twelve-lead electrocardiogram was performed prior to and during PTSA, and later electrocardiogram and vectorcardiogram according to Frank's method. The patients were followed up for 32 months. RESULTS - On electrocardiogram (ECG) prior to PTSA all patients had sinus rhythm and left atrial enlargement, 8 left ventricular hypertrophy of systolic pattern. On ECG immediately after PTSA, 8 had complete right bundle-branch block; 1 transient total atrioventricular block; 1 alternating transient bundle-branch block either right or hemiblock. On late ECG 8 had complete right bundle-branch block confirmed by vectorcardiogram, type 1 or Grishman. CONCLUSION - Septal fibrosis following alcohol injection caused a predominance of complete right bundle-branch block, different from surgery of myotomy/myectomy
