Wei Ding, Yinjia Ding, Hua Jiang
BACKGROUND: Although reduction mammaplasty is one of the most common procedures in plastic surgery, it is associated with some serious complications, especially in cases of severe hypertrophy or advanced ptosis, including necrosis of the nipple and areola, absence of normal sensation of the nipple-areolar complex, and loss of lactational function for future nursing. A thorough understanding of the breast anatomy is vital for successful reduction mammaplasty. This article describes the blood supply and innervation of the breasts, and introduces a modified round block technique for reduction mammaplasty based on this anatomy...

PURPOSE: Converting the measurable quantities to patient organ doses in projection radiography is usually based on a standard-sized patient model and a specific radiation quality, which are likely to differ from the real situation. Large inaccuracies can therefore be obtained in organ doses, because organ doses are dependent on the exposure parameters, exposure geometry and patient anatomy. In this study, the effect of radiation quality and patient thickness on the organ dose conversion factors were determined...

Cardiac late effects are a major health concern for long-term survivors after radiotherapy for breast cancer. Large cohort studies to better understand the exact dose-response relationship require individual estimates of radiation dose to the heart. To predict individual cardiac dose from information that is typically available for all members of a retrospective epidemiological cohort study, 774 female breast cancer patients treated with megavoltage tangential field radiotherapy in 1998-2008 were examined. All dose distributions were calculated using Eclipse with the anisotropic analytical algorithm (AAA) for photon fields and the electron Monte Carlo algorithm for electron boost fields...

AIM: Surgical treatment is still the cornerstone in the treatment of breast cancer, a very common neoplasia, particularly affecting the female elderly population. Axillary dissection is crucial in the treatment of some tumours, but variations in axillary vessels anatomy are poorly described in standard anatomy and surgical textbook. We aimed to describe anatomical variations in axillary vessels found in our institutional experience. PATIENTS AND METHODS: A prospective 3-year study was conducted in our institution from January 2012 to December 2014...

Limited data exist on the association between breast cancer treatments and coronary artery disease anatomy, particularly in males. We describe an unusual case of diffuse coronary ectasia in a man with breast cancer presenting with acute coronary syndrome (ACS). A 66-year-old man with breast cancer on paclitaxel, tamoxifen, and carboplatin chemotherapy regimen, presents with new onset chest pain. Electrocardiogram reveals anterolateral ST-segment depressions and elevated troponin I level. Emergent angiography revealed grossly ectatic coronary arteries with a total thrombotic occlusion of the mid right coronary artery...

BACKGROUND: Transoral endoscopic thyroidectomy by a vestibular approach (TOETVA) is a novel technique for thyroid gland excision. Compared to the transaxillary endoscopic and bilateral axillo-breast approaches, which require substantial dissection to reach the thyroid gland, TOETVA provides the most direct access to the target organ. METHODS: The aim of this video is to provide a step-by-step overview of TOETVA and demonstrate how to set up and utilize intraoperative nerve monitoring...

Over the past decades, imaging in oncology has been undergoing a "quiet" revolution to treat images as data, not as pictures. This revolution has been sparked by technological advances that enable capture of images that reflect not only anatomy, but also of tissue metabolism and physiology in situ Important advances along this path have been the increasing power of MRI, which can be used to measure spatially dependent differences in cell density, tissue organization, perfusion, and metabolism. In parallel, PET imaging allows quantitative assessment of the spatial localization of positron-emitting compounds, and it has also been constantly improving in the number of imageable tracers to measure metabolism and expression of macromolecules...

Autologous breast reconstruction utilizing a perforator flap is an increasingly popular method for reducing donor site morbidity and implant-related complications. However, aberrant anatomy not readily visible on computed tomography angiography is a rare albeit real risk when undergoing perforator flap reconstruction. We present an operative case of a patient who successfully underwent a bilateral breast reconstruction sourced from a unilateral abdominal flap divided into deep superior epigastric artery and superficial circumflex iliac artery flap segments...

RATIONALE AND OBJECTIVES: Different computed tomography imaging protocols and patient characteristics can impact the accuracy and precision of the calcium score and may lead to inconsistent patient treatment recommendations. The aim of this work was to determine the impact of reconstruction algorithm and gender characteristics on coronary artery calcium scoring based on a phantom study using computed tomography. MATERIALS AND METHODS: Four synthetic heart vessels with vessel diameters corresponding to female and male left main and left circumflex arteries containing calcification-mimicking materials (200-1000 HU) were inserted into a thorax phantom and were scanned with and without female breast plates (male and female phantoms, respectively)...

Sexual dimorphism in humans is mainly observed as a difference in the anatomy of genitals and breasts. There are also some differences in the stature and metric or morphological traits of the skeleton. Degree of sexual dimorphism varies among populations and depends on their genetic composition and various cultural and environmental factors. In this study, two Mediaeval Muslim populations from Granada, Spain, were compared, testing whether differences in living environment (urban vs. rural) would result in distinct degrees of sexual dimorphism of long bones...

Abdominal free flaps for microsurgical breast reconstruction are most commonly harvested based on the deep inferior epigastric vessels that supply skin and fat via perforators through the rectus muscle and sheath. Intact perforator anatomy and connections are vital for subsequent optimal flap perfusion and avoidance of necrosis, be it partial or total. The intraflap vessels are delicate and easily damaged and it is generally advised that patients should avoid heparin injection into the abdominal pannus preoperatively as this may compromise the vascular perforators through direct needle laceration, pressure from bruising, haematoma formation, or perforator thrombosis secondary to external compression...

BACKGROUND: Gynecomastia is a very common entity in men, and several authors estimate that approximately 50% to 70% of the male population has palpable breast tissue. Much has been published with regard to the etiology, diagnosis, and treatment of gynecomastia. However, the anatomy of the gynecomastia tissue remains elusive to most surgeons. PURPOSE: The purpose of this article was to define the shape and consistency of the glandular tissue based on the vast experience of the senior author (MB)...

BACKGROUND: The orofacial defect of cleft lip/palate (CL/P) involves an altered physiological anatomy that affects the infant's feeding ability. Infants have cleft lip (CL), cleft palate (CP), or both (CL/P). Dysfunction in the seal, as with cleft lip, or in the ability to coordinate muscle movement to generate negative pressure, as with cleft palate, leads to feeding issues that may compromise growth and affect bonding. PURPOSE: The purpose of this article is to present (1) scientific evidence that supports clinical feeding practices for the infant with CL/P and (2) teaching strategies for staff and parents...

We investigate the effect of anatomical noise on the detectability of cone beam CT (CBCT) images with different slice directions, slice thicknesses, and volume glandular fractions (VGFs). Anatomical noise is generated using a power law spectrum of breast anatomy, and spherical objects with diameters from 1mm to 11mm are used as breast masses. CBCT projection images are simulated and reconstructed using the FDK algorithm. A channelized Hotelling observer (CHO) with Laguerre-Gauss (LG) channels is used to evaluate detectability for the signal-known-exactly (SKE) binary detection task...
