A 79-year-old male patient with chronic atrial fibrillation and a history of mitral valve repair including ring annuloplasty several years ago underwent coronary angiography (fig. 1) for acute coronary syndrome, which showed the culprit lesion in the proximal left circumflex (LCx) artery. Angiography also showed a branch that arose just proximal to the culprit lesion, coursed on the left and th...

Femoral artery is frequently accessed by radiologists and surgeons. Anatomical knowledge of the variations of femoral artery and its branches including profunda femoris, medial and lateral femoral circumflex arteries is required to minimize complications and hence it is suggested for the clinicians planning surgery and intervention around the aforementioned vessels. Present study was undertaken...

Primary cardiac hemangioma is a very rare benign vascular tumor, with valvular hemangiomas being even less frequent as valves are generally avascular structures. We present the first case of mitral valve hemangioma in a renal transplant recipient. Patient presented with progressive dyspnea. Transesophageal echocardiogram (TEE) demonstrated a 0.8x0.9-cm pedunculated tumor mass on the posterior l...

Background The lateral arm flap is used for composite defects in need of vascularized soft tissue, skin, and bone. From its original description, the distal humeral metaphysis can be included with the flap, supplied by the periosteal extensions of the posterior branch of the radial collateral artery. We sought to reexplore the anatomy of the lateral arm to determine its utility as a donor site ...

The success of anatomic reattachment of the tuberosities in proximal humeral fractures, treated with hemiarthroplasty, correlates with functional results. The purpose of this study was to determine the value of the upper edge of the pectoralis major insertion (PMI) as a landmark to establish the proper height and version of hemiarthroplasty implanted for proximal humeral fractures. Twenty cadav...

We compared myocardial infarct size produced by permanent occlusion of the middle left anterior descending (LAD) or circumflex (LCx) coronary artery in the anesthetized dog. The dogs were killed 3-10 days later, and the occluded coronary bed was visualized by postmortem arteriography. The outlines of the infarct and occluded bed were marked on tracings of weighed left ventricular (LV) rings and...

Restoration of joint stability during total shoulder arthroplasty can be challenging in the face of severe glenoid retroversion. A novel technique of humeral head component anterior-offsetting has been proposed to address posterior instability. We evaluated the biomechanical benefits of this technique in cadaveric specimens. Total shoulder arthroplasty was performed in 14 cadaveric shoulders fr...

Displaced Lisfranc fracture with the arterial supply of the foot superimposed. The division of the dorsalis pedis artery (not shown) at its junction with the plantar arterial arch is present in all degrees of this fracture and is not in itself a dangerous injury. When to this injury is added excessive torsion of the main lateral plantar artery or of the posterior tibial artery behind the medial...

Chronic posterior glenohumeral joint instability can be a challenging clinical entity for patients and surgeons alike. In the setting of a posterior dislocation, a large anterior humeral impaction injury (reverse Hill-Sachs [HS]) may occur, leading to engagement of the humerus with the posterior glenoid bone, especially during internal rotation of the joint. A reverse HS is especially debilitat...
