Effect of carotid artery stenting on ophthalmic artery flow patterns.

Objectives: The purpose of this study was to assess the effect of carotid artery stenting on ophthalmic artery blood flow using transorbital color and spectral Doppler sonography and review the changes in relation to cerebral hemodynamics.

Methods: Twenty-eight consecutive patients with severe internal carotid artery stenosis (≥ 70%) who were scheduled for carotid stenting were included. Ophthalmic artery Doppler sonography was performed bilaterally before and after stenting.

High frequency of kidney and urinary tract anomalies in asymptomatic first-degree relatives of patients with CAKUT.

Background: Congenital anomalies of the kidney and urinary tract (CAKUT) commonly cause chronic kidney disease in children. While most CAKUT cases are sporadic, observed familial clustering suggests that the pathogenesis is influenced by genetic factors.

Methods: The purpose of the present study is to determine the frequency of the kidney and urinary tract anomalies in asymptomatic first-degree relatives of patients with CAKUT.

Clinically Positive Axillary Lymphadenopathy May Lead to False Diagnosis of Overstaged Breast Cancer in Patients with Sjögren's Syndrome: A Case Report.

Sjögren's syndrome (SS) is an autoimmune disease that chronic inflammation and lymph node proliferation. Patients with SS carry a greater risk of developing lymphoproliferative malignancy. In addition to other organ cancers, breast cancer may also occur in these patients.

Is there an association between mastalgia and fibromyalgia? Comparing prevalence and symptom severity.

To determine the prevalence of mastalgia in patients with fibromyalgia (FM) and the prevalence of FM in patients with mastalgia in order to investigate coexistence, and to compare the pain patterns in the case of mastalgia or FM alone versus the two in combination. Fifty consecutive patients with mastalgia and 50 consecutive patients with FM were assessed and examined both for the existence and severity of mastalgia and FM. A high proportion of patients with mastalgia (36%) fulfilled the criteria for FM and 42% had mastalgia in the FM group.

The significance of the right hepatic artery originating from the superior mesenteric artery in patients with cavernous transformation of the portal vein.

Purpose: Dilatation of the hepatic artery in response to decrease in portal vein flow is known as hepatic arterial buffer response (HABR). In this study, the effect of HABR on variant hepatic arterial anatomy is investigated by analyzing the frequency of the right hepatic artery originating from the superior mesenteric artery (variant artery) and by determining the diameters of variant artery and common hepatic artery (CHA) in patients with cavernous transformation of the portal vein.

Materials And Methods: Forty-one patients who were referred for contrast-enhanced abdominal magnetic resonance angiography were retrospectively evaluated in two groups: group 1 (n = 15), cirrhotic patients with cavernous transformation of the portal vein; and group 2 (n = 26), cirrhotic patients without cavernous transformation of the portal vein.

Lupus mastitis is not a surgical disease.

A 23-year-old woman with a 2-year history of discoid lupus (SLE) presented with a right lateral upper quadrant breast mass. Physical examination revealed a 5 cm irregular, hard lesion suggestive of a breast malignancy. Ultrasound-guided fine needle aspiration biopsy of the mass confirmed the diagnosis as lupus mastitis.

Synovial cyst: an uncommon cause of back pain.

Synovial cyst is an uncommon cause of back pain and radiculopathy. This case report describes the magnetic resonance imaging findings of two lumbar synovial cysts with special emphasis on the differential diagnoses of other extradural cystic lesions.

Direct contrast-enhanced 3D MR venography evaluation of upper extremity deep venous system.

Purpose: To investigate the diagnostic value of direct contrast-enhanced three dimensional magnetic resonance (3D MR) venography in mapping the deep venous system of the upper extremities and to plan potential interventional procedures.

Materials And Methods: Nineteen cases with the diagnoses of end-stage renal disease with multiple hemodialysis catheter access were examined. Direct contrast-enhanced 3D MR venograms were obtained with 1.

Primary sclerosing cholangitis: MR cholangiopancreatography and T2-weighted MR imaging findings.

Purpose: To present MR cholangiopancreatography (MRCP) findings and to determine the hepatic morphological changes of primary sclerosing cholangitis (PSC) seen on T2-weighted fast spin echo (FSE) images.

Materials And Methods: Twenty-three patients (15 women, 8 men) with ages ranging from 17 to 80 years (median, 45.1 years) were included in the study.

The role of classic spin echo and FLAIR sequences for the evaluation of myelination in MR imaging.

Purpose: The aim of this study was to assess the features of the normal brain development in terms of myelination in infants and young children on fluid-attenuated inversion recovery (FLAIR) magnetic resonance (MR) imaging, and to determine if FLAIR imaging is superior to spin echo MR sequences.

Materials And Methods: T1-weighted (T1W) fast spin echo T2-weighted (FSE T2W), and FLAIR images were obtained in 76 pediatric patients between the ages of 0 and 48 months, on a 1 Tesla MR unit. On these images, the signal intensities of 16 different white matter regions were compared to those of adjacent gray matter, and for each brain region.

[Anatomic variations of the bile ducts: MRCP findings].

Purpose: Anatomic variations of intra or extrahepatic bile ducts may be problematic during surgical procedures. Besides iatrogenic trauma of the bile ducts during cholecystectomy, formation of bile duct stones, recurrent pancreatitis, cholangitis and biliary malignancies can be seen. The aim of this study was to evaluate the frequency of anatomic variations of the biliary tree and to present the magnetic resonance cholangiopancreatography (MRCP) findings.

[Late presentation of an extrarenal pseudoaneurysm in a renal transplant patient: CT and color Doppler US findings (case report)].

Vascular complications associated with renal transplants are a significant cause of graft dysfunction or failure. The most common complications are arterial and venous stenoses/thromboses, intrarenal and extrarenal arteriovenous fistulas, and pseudoaneurysms. In this case report, an extremely rare complication following renal transplantation, an extrarenal pseudoaneurysm, is presented with CT, gray scale, and color Doppler US findings.
