USEFULNESS OF GASTRIC SUBMUCOSAL DISSECTION DEPTH TO EVALUATE SKILL ACQUIREMENT IN SHORT TERM TRAINING COURSES IN ESD: AN EXPERIMENTAL STUDY.

Arq Gastroenterol 2018 Jul-Sep;55(3):221-229

Universidade de São Paulo, Faculdade de Medicina, Departamento de Endoscopia Gastrointestinal, SP, Brasil.

Background: Endoscopic submucosal dissection (ESD) is a complex endoscopic procedure, with high rates of adverse events and technical difficulties. To overcome that problem, many training centers published the importance of animal models for skill acquirement in ESD. However, no study has used the submucosal dissection depth (DSUB) as a parameter to evaluate the learning curve in ESD, which might be a relevant factor since an optimal resection plane is important to achieve a curative resection and avoid intraoperative complications.

Myocardial infarction complicates approximately 1 in 10,000 pregnancies [1]. Coronary artery dissection is the leading cause of pregnancy-related myocardial infarction during the postpartum period. Proposed etiologies include altered endocrine status, hemodynamic stress, eosinophilic inflammatory infiltrate, and disruption of vasa vasorum. Read More

Multivessel spontaneous coronary artery dissection associated with hormonal infertility therapy in a 39-year-old female.

J Cardiol Cases 2012 Apr 6;5(2):e69-e72. Epub 2012 Mar 6.

Division of Cardiovascular Diseases, Mayo Clinic, Rochester, MN, USA.

Spontaneous coronary artery dissection (SCAD) is a rare and potentially lethal cause of chest pain and myocardial infarction in healthy young individuals. It more commonly affects females and has been correlated with hormonally-induced connective tissue changes in pregnancy and oral contraceptive use. We present the case of a previously healthy 39-year-old woman with multivessel SCAD associated with recent clomiphene and gonadotropin therapy for infertility, which is not a previously reported association, and we assert that this should be in the differential diagnosis of such patients with chest pain or myocardial infarction.

Coarctation of the aorta with some collaterals presenting as aortic dissection detected by 64-MDCT.

J Cardiol Cases 2012 Feb 4;5(1):e48-e50. Epub 2011 Oct 4.

Department of Cardiology, Fukuoka University School of Medicine, Fukuoka, Japan.

Coarctation of the aorta with aortic dissection is sometimes seen in cases of Turner syndrome, and most cases are type A aortic dissection, whereas coarctation of the aorta with type B aortic dissection is unusual. Only two cases of coarctation of the aorta presenting as aortic dissection have been reported in Japan, and only a few cases have been reported worldwide. We report here a case of coarctation of the aorta with some collaterals presenting as aortic dissection (type B) detected by 64-multidetector row computed tomography (MDCT). Read More

Silent pulmonary artery dissection in a centenarian.

J Cardiol Cases 2012 Feb 6;5(1):e36-e38. Epub 2011 Dec 6.

Department of Cardiology, Matsushita Memorial Hospital, Osaka, Japan.

Pulmonary artery dissection is an extremely rare and fatal disease that is difficult to diagnose. We report a case of a 97-year-old woman with heart failure, who was diagnosed as having silent pulmonary artery dissection by chance during transthoracic echocardiography. Surgical treatment for pulmonary artery dissection was not performed, but the patient has been doing well in a sanatorium for more than 2 years, being a centenarian. Read More

Postpartum multivessel coronary artery dissection treated with coronary artery bypass grafting.

J Cardiol Cases 2012 Feb 8;5(1):e23-e27. Epub 2011 Dec 8.

Hadassah University Hospital, Jerusalem, Israel.

Spontaneous coronary artery dissection is a rare but potentially life-threatening event associated with the peripartum period. We present a case of acute anterolateral ST elevation myocardial infarction in the postpartum period in a young woman. Thrombolytic therapy was successful, but later the patient required emergent coronary artery bypass grafting due to another acute inferolateral myocardial infarction that developed 4 h after cardiac catheterization which showed multivessel spontaneous coronary artery dissection.
