PURPOSE: Mediastinal radiation therapy (RT) for Hodgkin lymphoma (HL) is associated with late cardiotoxicity, but there are limited data to indicate which dosimetric parameters are most valuable for predicting this risk. This study investigated which whole heart dosimetric measurements provide the most information regarding late cardiotoxicity, and whether coronary artery dosimetry was more predictive of this outcome than whole heart dosimetry. METHODS AND MATERIALS: A random sample of 125 HL patients treated with mediastinal RT was selected, and 3-dimensional cardiac dose-volume data were generated from historical plans using validated methods...

BACKGROUND: Knowledge of the vascular supply of the femoral head is crucial for hip-preserving surgical procedures. The critical area for reshaping cam deformity is at the retinacular vessel penetration, an area with ill-defined topographic anatomy. We performed a cadaver study of the extension of the lateral retinaculum near the head-neck junction, distribution of the arterial vascular foramina, and initial intracapital course of these vessels. METHODS: In 16 fresh proximal parts of the femur without head-neck deformities, the deep branch of the medial femoral circumflex artery was injected with gadolinium for magnetic resonance imaging (MRI) sequences to identify arterial structures...

A neck scar contracture can severely and negatively affect the function of mastication, phonic, or breathing and result in neck pain and issues with esthetics. The best way is of course to avoid such contracture by means of non-surgical treatment such as use of a growth factor. The basic fibroblastic growth factor is clinically well proven in decreasing scar formation and improving healing. There are numerous reconstructive methods for neck contracture, especially when the lesions are relatively limited in part of the neck...

In free-flap reconstruction of the lower extremity, due either to trauma or pre-existing vascular disease, healthy vessels may not be readily available in the proximity of the defect. A variety of options including a cross-leg free flap, vein grafts, arteriovenous loops, and "bridging" flaps have been used to address the issue. The purpose of this report is to present a case in which a 72-cm long extended bilateral deep inferior epigastric artery perforator (DIEP) free flap was used for coverage of a 20 × 25 cm soft tissue defect of the lower leg following a Gustilo grade IIIC fracture in a 29-year-old man...

A 54-year-old gentleman presented with pulmonary oedema secondary to anterolateral papillary muscle (PPM) rupture and acute mitral regurgitation subsequent to myocardial ischaemia (MI). Angiography revealed complete occlusion of the first obtuse marginal (OM1) branch of the circumflex coronary artery and a 70% occlusion of the left anterior descending (LAD) coronary artery. Operatively, unusual anatomy was noted; an accessory head was attached superiorly to the anterior lateral PPM. This gave rise to chordae that were subsequently attached to the posterior second (P2) scallop...

BACKGROUND: An aberrant origin of the left coronary artery (LCA) from the right coronary cusp (RCC) is an extremely rare congenital anomaly. We here report on successful percutaneous coronary intervention (PCI) in a patient presenting with acute coronary syndrome and an aberrant origin of the LCA from the RCC. CASE PRESENTATION: A 50-year-old man presented at our emergency department with recurrent resting chest pain. Following unsuccessful attempts at visualizing the left coronary artery using Judkins left and Amplatz catheters, an aortogram using a pigtail catheter suggested anomalous left coronary artery origin and showed a significant occlusive lesion at proximal left anterior descending artery...

The circumflex aorta is a rare type of true vascular ring anomaly. It consists of a retroesophageal right aortic arch, a left-sided descending thoracic aorta, and a left-sided ligamentum arteriosum. The "aortic uncrossing procedure" described by Planché and Lacour-Gayet is the procedure of choice for managing this aortic anomaly in patients with a biventricular heart. The presence of a circumflex aorta in a patient with heterotaxy syndrome and univentricular congenital heart disease requiring Norwood palliation is highly unusual...

The most important factor for preventing contrast-induced nephropathy (CIN) during percutaneous coronary intervention (PCI) in patients with severe renal dysfunction is to minimize the contrast volume. Herein, we report a successful case of complete revascularization after 3 separate PCI procedures using a super-low volume of contrast medium in a patient with 3-vessel disease, including two chronic total occlusions (CTOs). A 70-year-old man having exertional angina despite maximal medical therapy was referred to our hospital...

Large defects after skin malignant tumors resection were difficult to repair. We introduced a partition concept, in which the large defects were divided into several subunits, and each subunit was repaired by a certain pedicled flap to achieve a complete coverage.Between May 2012 and Oct 2016, 8 patients with skin malignant tumors underwent radical resection. Prior to surgery, the dimension of the potential defect after tumor ablation was estimated and outlined. After evaluation, the partition concept was applied and the defects were divided into several subunits...

Single coronary artery is an extremely rare congenital coronary anomaly in which the entire coronary arterial system arises from a solitary ostium. The Lipton's classification is used for single coronary artery anomalies. Herein, we present a 72-year-old woman with single coronary artery anomaly admitted with atypical chest pain. Coronary angiography and multidetector computed tomography coronary angiography findings were shared.

BACKGROUND: Several recipient vessels can be used in free microsurgical fibula flaps (MFFs) for the treatment of avascular necrosis of the femoral head (ANFH). Few articles investigate the influence of different recipient vessels on outcomes of MFF for ANFH. METHODS: A comprehensive literature search of databases including PubMed-Medline, Ovid-Embase, and Cochrane Library was performed to collect the related studies. The Medical Subject Headings used were "femur head necrosis" and "bone transplantation...

A 53-year-old man underwent percutaneous coronary intervention of a chronic total occlusion of the circumflex artery. A mini-crush stent technique with two drug-eluting stents was performed. To the best of our knowledge, this is the first case of coronary artery aneurysm affecting a bifurcated chronic total occlusion treated with a two-stent technique.

INTRODUCTION: Neck burn sequelae remain a major challenge for the reconstructive surgeon. To achieve satisfactory functional and aesthetic results, the anterior neck aesthetic unit must be covered as a single unit. In cases where free flaps are required, harvesting a flap of sufficient size can cause major donor site morbidity. In 1994, we published our favorable 6-year experience of reconstructing neck burn sequelae with an extended circumflex scapular flap (ECSF). Since then, we have made several modifications to the technique, resulting in improved long-term functional and aesthetic results...

Anomalous coronary artery origin is a rare, but important cause of cardiac ischemia, particularly in younger patients. These anomalies of origin can be divided into two groups, benign or malignant, based on their propensity to cause ischemia or sudden death. Symptomatic, or malignant coronary artery anomalies are usually described with respect to anomalous origins of the right coronary artery or left main coronary artery. We present a unique case of a previously unreported entity, an anomalous left circumflex coronary artery causing ischemia...

We describe a 4-year-old girl with anomalous origin of the left circumflex coronary artery from the right pulmonary artery and large atrial septal defect. This is the first reported case of such association. Surgical reimplantation of the anomalous left circumflex coronary artery to the aorta and atrial septal defect surgical closure was performed, with no postoperative complications.

BACKGROUND: Coronary anomalies are frequently present in children with transposition of the great arteries (TGA). Such anomalies significantly increase the complexity of arterial switch operations and may have an effect on postoperative outcomes. In this study, we aimed to assess the frequency of coronary anomalies in children with TGA and describe their effect on postoperative outcomes. METHODS: All patients with TGA who underwent an arterial switch operation between 1991 and 2015 were consecutively enrolled in this study...

AIM OF THE STUDY: Alprostadil (A) induces smooth-muscle relaxation by stimulating the increasing of intracellular cAMP. Intra-urethral administration is an alternative to its intra-cavernose injection in inducing erection. In order to understand the functional and anatomical basis for drug transfer, the possible communications of the corpus spongiosum with the corpora cavernosa were studied. MATERIAL OF STUDY: A "Spongiogram" (SP) was performed in 44patients (pt...
