This is to evaluate the predictive ability of clinical examination and preoperative magnetic resonance imaging (MRI) for the staging of early cervical cancer. We prospectively evaluated 115 patients with cervical cancer, International Federation of Gynecologic and Obstetrics (FIGO) stage <IIB; receiver operating characteristic (ROC) analysis determined the(More)
OBJECTIVE to present our experience with stent placement in renal arteries in solitary kidneys for treating renal insufficiency. DESIGN retrospective analysis. MATERIALS in 26 patients with solitary kidney (17 men, 9 women, mean age: 63 years), presented with renal insufficiency (se-creat >0.144 mmol/l), stent was placed in a stenosed renal artery. We(More)
For pancreatic insulinomas, the treatment of choice is surgical excision, which when successful is curative. Intraoperative palpation combined with ultrasonography theoretically depict almost all tumors, however the accuracy of palpation is improved by the preoperative localization. All recent advances in imaging have improved the likelihood for curative(More)
We describe the sonographic, computed tomography and magnetic resonance imaging findings of two patients with histologically proven hepatic hemangioendothelioma. Both patients presented with multiple liver nodules. Color Doppler ultrasound demonstrated moderate vascularity at the periphery of the nodules, as well as central neovascularity. On enchanced(More)
BACKGROUND/AIMS The purpose of this study was to correlate blood flow velocity in the superior mesenteric artery and activity of ulcerative colitis. METHODOLOGY Doppler spectral analysis of superior mesenteric artery blood flow velocities were obtained in a blind study from 28 patients after fasting (A1: 13 patients with pancolitis, A2: 5 patients with(More)
Tailgut cysts are unusual cystic tumors of the retrorectal space. We describe the findings of three cases. Constipation, intrapelvic fullness and low abdominal pain were the most prominent clinical manifestations. One patient developed an abscess. Ultrasound, computed tomography and MR imaging demonstrated the presacral lesions. Transabdominal excision of(More)
BACKGROUND Comparison of carotid endarterectomy in patients with and without occluded contralateral carotid artery. METHODS DESIGN evaluation of results without using shunt or patch. SETTING <<Aretaeion>> Hospital, Medical School, University of Athens. SUBJECTS 235 patients, divided into group I of 40 patients with and group II of 195 patients(More)
Carotid endarterectomy is a method of prophylaxis. A total of 367 carotid endarterectomies in 335 patients were performed during the period of 1989-1997: 222 (66.3%) were symptomatic and 113 (33.7%) asymptomatic patients. In all, 262 (78.2%) had unilateral, 41 (12.2%) contralateral occlusion and 32 (9.6%) bilateral artery disease. All were operated on under(More)
OBJECTIVE Bilateral carotid stenoses are actually managed by staged endarterectomy. The present study compares the results of the above surgical procedure with simultaneous bilateral carotid endarterectomy. METHODS Sixty-four carotid endarterectomies were carried out on two groups of thirty-two patients with bilateral carotid stenoses. Fifteen patients(More)
