Use of the gamma probe in sentinel lymph node biopsy in patients with prostate cancer.

Objective: To describe the reproducibility of the sentinel lymph node technique in patients with prostate cancer and verify if there is improved accuracy over modified lymphadenectomy.

Material And Methods: Twenty-three patients with biopsy proven prostate cancer were enrolled in this study. Lymphoscintigraphy was performed after the transrectal administration of Tc sulfur colloid guided by ultrasound, with one injection in each prostate lobe.

[Thromboembolism of the right coronary after ventricular tachycardia with inferior wall myocardial infarction and normal coronary arteries and intracavitary thrombus].

A 47 year-old man, with signals of low cardiac output due to sustained ventricular tachycardia, without history of pain. After clinical control of the arrhythmia, he was underwent to coronary-angiography that showed no obstructive lesion, but a thrombus was present in the distal right coronary artery. There was hypocinesia of the inferior wall of the left ventricle and the presence of a mural thrombus in that region.

[Ostial occlusion of the left coronary artery in a female patient with chronic stable angina. The coronary cineangiographic aspect].

The left main coronary artery occlusion is the most dangerous presentation of arteriosclerotic coronary artery disease, often resulting in hemodynamics and electrical instability that ultimately lead to death (fatal acute episodes and/or sudden death). A 47-years-old female with multiple risk factors went on a cardiologic check-up, including coronary angiograms, as a preoperative evaluation of a routine abdominal surgical procedure. The angiograms provided definite information about the coronary vessels including total occlusion of the ostium of the left main coronary artery (LCA) and collateral circulation from the right coronary artery (RCA).
