CONTEXT: The internal mammary artery perforator vessels (IMPV) as a recipient in free flap breast reconstruction offer advantages over the more commonly used thoracodorsal vessels and the internal mammary vessels (IMV). AIMS: This study was designed to assess the anatomical consistency of the IMPV and the suitability of these vessels for use as recipients in free flap breast reconstruction. PATIENTS AND METHODS: Data from ten randomly selected female patients who did not have any chest wall or breast pathology but had undergone a computed tomography angiography (CTA) for unrelated diagnostic reasons from April 2013 to October 2013 were analysed...

OBJECTIVE: Minimally invasive coronary artery bypass grafting (MICS CABG) via a small left thoracotomy is a novel technique for coronary revascularization that is increasingly used around the world. However, multivessel MICS CABG is difficult, and concerns about repeat revascularization (RR) have been raised. This longitudinal study describes the rates of RR among patients who have undergone MICS CABG and identifies targets for improvement. METHODS: A prospective observational study was performed on the 306 MICS CABG patients operated on by a single surgeon from 2005 to 2015...

We present an uncommon and underreported complication of coronary artery bypass graft surgery: erroneous anastomosis of the left internal mammary artery to the great cardiac vein. The iatrogenic aorto-coronary arteriovenous fistula with left-to-right shunting resulted in dilation of the coronary sinus, a supporting secondary finding. Factors predisposing to this inadvertent anastomosis include an intramyocardial segment of the left anterior descending coronary artery, demonstrated in this case, as well as epicardial fat and potentially fibrosis of the underlying myocardium...

Anomalous origin of the right coronary artery originating from the pulmonary trunk (ARCAPA) is a rare congenital coronary anomaly with an estimated prevalence of 0.002%. Most patients are asymptomatic and the anomaly is detected incidentally during evaluation for other problems. Occasionally, ARCAPA may lead to myocardial ischemia and/or sudden cardiac arrest. We present a case of a 55-year-old female with a history of hypertension who presented to the emergency department with intermittent chest discomfort for three days...

BACKROUND: Coronary bypass surgery using the internal mammary artery (IMA) is among the most commonly performed procedures in treatment of advanced coronary vessel disease. Further, bilateral harvesting of the IMA is associated with increased rates of sternal wound infections. OBJECTIVE: This study aimed to explore changes in sternal perfusion, following left internal mammary artery (LIMA) harvesting. METHODS: 60 patients were divided equally into intervention- and control cohorts and underwent assessment of oxygen saturation (sO2) and relative blood flow (RBF) by laser doppler flowmetry remission spectroscopy preoperatively, 24 h and 72 h postoperatively...

Castleman's disease (CD) is a rare lympho-proliferative disorder due to faulty immune regulation resulting in proliferation of lymphatic tissue. The vascular supply to these lesions have been reported to arise from the bronchial, internal mammary and the intercostal arteries. We report a case of hemoptysis secondary to intrathoracic CD with vascular supply arising from the left inferior phrenic artery which was successfully embolised with polyvinyl alcohol (PVA) particles.

The clinical benefits of using the left internal mammary artery (LIMA) to bypass the left anterior descending artery are well established making it the most frequently used conduit for coronary artery bypass surgery (CABG). Coronary subclavian steal syndrome (CSSS) occurs during left arm exertion when (1) the LIMA is used during bypass surgery and (2) there is a high grade (≥75%) left subclavian artery stenosis or occlusion proximal to the ostia of the LIMA resulting in "stealing" of the myocardial blood supply via retrograde flow up the LIMA graft to maintain left upper extremity perfusion...

Coexistence of aortic coarctation with aneurysm of subclavian artery is a uncommon situation and may require unusual treatment in patients. A 40-year-old patient diagnosed incidentally with left subclavian artery aneurysm coexisting with aortic coarctation. Patient was initially referred for hybrid treatment. Initially ostium of the left subclavian artery was covered with a stent-graft. Over a 30-month follow-up period aneurysm became thrombosed all the way up to the ostium of internal mammary artery. The patient did not present with neurological symptoms or signs of upper limb ischemia...
