Purpose To study the distribution of choroidal thickness (CT) in and outside of the vascular arcade, as well as at the fovea in healthy eyes using spectral-domain optical coherence tomography (OCT). Methods Seventy healthy eyes were examined with OCT to obtain nine horizontal lines in and outside of the vascular arcade. Nine points including the central point of the line were chosen in 0.5-mm...

OBJECTIVE To determine the accuracy of the use of multi-detector row CT (MDCT) to predict vascular anatomy in living kidney donors and to reveal the prevalence of vascular variations in a Korean population. MATERIALS AND METHODS A total of 153 living kidney donors that had undergone preoperative CT and nephrectomy, either with open or laparoscopic surgery, were selected retrospectively. The i...

BACKGROUND Delaying flap rotation for 48 to 72 hours leads to opening of choke anastomotic vessels linking adjacent vascular territories. This mechanism enhances flap circulation. Lateral supramalleolar flap with larger dimensions or vascular variations can potentially have survival problems. The purpose of this study is to assess the outcome of delayed lateral supramalleolar flap. METHODS Th...

BACKGROUND The anterolateral thigh flap is known for variations of its vascular pedicle. This is a prospective intraoperative analysis of the vascular anatomy of the lateral thigh that focuses on clinically important variations that impact flap harvest. METHODS Eighty-nine consecutive anterolateral thigh flaps were harvested. A detailed intraoperative analysis was performed of the vasculature...

BACKGROUND Articular osteochondrosis is a common cause of leg weakness in pigs and is defined as a focal delay in the endochondral ossification of the epiphysis. The first demonstrated steps in the pathogenesis consist of loss of blood supply and subsequent chondronecrosis in the epiphyseal growth cartilage. Blood vessels in cartilage are located in cartilage canals and become incorporated into...

PURPOSE Fractal dimension of retinal vasculature is a global summary measure of retinal vascular network pattern and geometry. This study was conducted to examine the effect of variations in image color, brightness, focus, contrast, and format on the measurement of retinal vascular fractal dimension. METHODS A set of 30 retinal images from the Blue Mountains Eye Study was used for a series of...

Introduction: Since palmaris longus tendon is the first choice for grafting, its anatomical variation is important. This study was designed to find the anatomical variations of this tendon in Iranian population by performing a study on cadaver. Method: In this study, 150 forearms belonged to 75 cadavers were studied. After exploring the proximal end of tendon, tendon width was measured at its p...

BACKGROUND Pseudoaneurysm formation is rare complication after arthroscopy with incidence of 0.008%, easy to misdiagnose. Its potential catastrophic sequelae should not be underestimated. CASE PRESENTATION We present a case of missed diagnosis of traumatic anterior tibial artery pseudoaneurysm in a 39 years old female, instead treated as post operative arthroscopy infection. The diagnosis was...

a survey was carried out in citrus nurseries in mazandaran and kerman provinces as the major citrus growing regions of iran. different varieties of orange and tangerine with abnormal symptoms were examined for the occurrence of candidatus liberobacter asiaticus, spiroplasma citri and phytoplasma as the most important vascular limited pathogens in citrus. by visual inspection and molecular exami...

introduction hemangiopericytomas (hpcs) are rare neoplasms which account for approximately 1% of primary vascular tumors. case presentation we report a 73 years old woman with vague abdominal pain who did not have further significant symptoms and was diagnosed to have retroperitoneal hemangiopericytoma. discussion the tumor was initially diagnosed by ultrasound evaluation. mri showed a lobulate...
