The bicipital groove is an important landmark for humeral head placement in fractures of the proximal humerus. It contains the long head of the biceps brachii muscle, its synovial sheath and an ascending branch of the anterior circumflex humeral artery. The BG & LBT are intimately related. The shape of the BG has a great impact on the tendency for the LBT to be dislocated or subluxated. A shall...

The amount of cross-sectional area narrowing by atherosclerotic plaque in each 5-mm-long segment from the entire lengths of the right, left main, left anterior descending and left circumflex coronary arteries and the size, predominant location and extent of myocardial scarring were determined in 59 necropsy patients with a healed transmural myocardial infarct (MI). The mean number of the four m...

A 16-year-old woman with severe mitral regurgitation as a result of rheumatic heart disease underwent mitral valve repair with posterior mitral annuloplasty. ST elevation was observed in leads II, III and aVF after weaning from cardiopulmonary bypass. On transesophageal echocardiography, the stenosis of the circumflex artery was suggested by a modified midesophageal long axis. Since the patient...

It is becoming increasingly important for clinicians to identify a safer intramuscular (IM) injection site in the deltoid muscle because of possible complications following the vaccine administration of IM injections. We herein examined 4 original IM sites located on the perpendicular line through the mid-acromion to establish a safer IM injection site. Thirty healthy volunteers participated in...

Background: Fractional flow reserve (FFR) uses pressure-based measurements to assess the severity of a coronary stenosis. Distal pressure (Pd) is often at different vertical height that proximal aortic (Pa). The difference in between Pd and Pa due hydrostatic pressure, may impact FFR calculation. Methods: One hundred computed tomography angiographies were used measure differences ostia points t...

background :in addition to diagnosing the acute myocardial infarction (mi), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting mi. many studies have been conducted to predict the occlusion site by interpreting the st segment deviations in electrocardiogram (ecg).additional posterior and right precordi...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013010303 DESCRIPTION The posterior descending artery (PDA) arises from the right coronary artery (RCA) in approximately 85% of people in right dominant circulation. Whereas only in 10–15% of cases, it arises from the circumflex artery (LCX) or from both RCA and LCX. Rarely ...

Case History: A 62-year-old male with a history of hypertension and coronary artery disease with prior stenting to the left circumflex artery presented with chest pain. Echocardiography on admission demonstrated a globally reduced ejection fraction of 10% to 15% with regional wall-motion abnormality consistent with prior anterior and inferolateral infarction. End-diastolic volume of the left ve...

The inferior gluteal artery is described in standard anatomy textbooks as contributing to the blood supply of the hip through an anastomosis with the medial femoral circumflex artery. The site(s) of the anastomosis has not been described previously. We undertook an injection study to define the anastomotic connections between these two arteries and to determine whether the inferior gluteal arte...
