SummaryThe objectives of this observational study were to investigate whether varicography has additional value to CFDI in clarifying the nature and source of recurrent varicose veins below the knee after varicose vein surgery and to investigate the possible role of incompetent perforating veins (IPV) in these recurrent varicose veins. Patients, material, methods: 24 limbs (21 patients) were included. All patients were assessed by a preoperative clinical examination and CFDI (colour flow duplex imaging). Re-evaluation (clinical and CFDI) was done two years after surgery and varicography was performed. Primary endpoint of the study was the varicographic pattern of these visible varicose veins. Secondary endpoint was the connection between these varicose veins and incompetent perforating veins. Results: In 18 limbs (75%) the varicose veins were part of a network, in six limbs (25%) the varicose vein appeared to be a solitary vein. In three limbs (12.5%) an incompetent sapheno-femoral junction was found on CFDI and on varicography in the same patients. In 10 limbs (41%) the varicose veins showed a connection with the persistent below knee GSV on varicography. In nine of these 10 limbs CFDI also showed reflux of this below knee GSV. In four limbs (16%) the varicose veins showed a connection with the small saphenous vein (SSV). In three limbs this reflux was dtected with CFDI after surgery. An IPV was found to be the proximal point of the varicose vein in six limbs (25%) and half of these IPV were detected with CFDI as well. Conclusion: Varicography has less value than CFDI in detecting the source of reflux in patients with recurrent varicose veins after surgery, except in a few cases where IPV are suspected to play a role and CFDI is unable to detect these IPV.

Summary Aim: In order to evaluate the diagnostic efficiency of arthroscintigraphy in suspected rotator cuff ruptures this new imaging procedure was performed 20 times in 17 patients with clinical signs of a rotator cuff lesion. The scintigraphic results were compared with sonography (n = 20), contrast arthrography (n = 20) and arthroscopy (n = 10) of the shoulder joint. Methods: After performing a standard bone scintigraphy with intravenous application of 300 MBq 99m-Tc-methylene diphosphonate (MDP) for landmarking of the shoulder region arthroscintigraphy was performed after an intraarticular injection of 99m-Tc microcolloid (ALBURES 400 μCi/5 ml). The application was performed either in direct combination with contrast arthrography (n = 10) or ultrasound conducted mixed with a local anesthetic (n = 10). Findings at arthroscopical surgery (n = 10) were used as the gold standard. Results: In case of complete rotator cuff rupture (n = 5), arthroscintigraphy and radiographic arthrography were identical in 5/5. In one patient with advanced degenerative alterations of the shoulder joint radiographic arthrography incorrectly showed a complete rupture which was not seen by arthroscintigraphy and endoscopy. In 3 patients with incomplete rupture, 2/3 results were consistant. A difference was seen in one patient with a rotator cuff, that has been already revised in the past and that suffered of capsulitis and calcification. Conclusion: Arthroscintigraphy is a sensitive technique for detection of rotator cuff ruptures. Because of the lower viscosity of the active compound, small ruptures can be easily detected, offering additional value over radiographic arthrography and ultrasound, especially for evaluation of incomplete cuff ruptures.

Abstract New research has addressed many of the early concerns of Computed Tomographic colonography (CTC) and these studies are now beginning to shape clinical practices. A review of the literature demonstrates that the sensitivity of CTC in screening for large polyps (≥ 1cm) or cancers in the large intestine is as high as that of conventional optical colonoscopy, however, the sensitivity decreases with the diameter of the polyp. Despite this, CTC is well tolerated, more acceptable to patients than optical colonoscopy and therefore may improve colorectal cancer screening compliance. This review not only describes the diagnostic accuracy and sensitivity of CTC, and the evolving role of CTC as a primary colon cancer screening option, but also the recent studies that have demonstrated the additional value of CTC utilization for practicing clinicians.

ABSTRACTImplants are essential for the repair of retinal detachments. The implant buckles the wall of the eye and apposes the detached retina with the choroid, thus restoring light sensitivity to the retina. The scleral buckling also relieves traction on the retina from a shrinking vitreous body. The implant materials most commonly used are solid silicone rubber and silicone sponges, but both types have some disadvantages. A poly(hydroxyethyl acrylate-co-methyl acrylate) hydrogel implant with improved properties of softness and antibiotic absorption is also available for retinal detachment surgery. Proliferative vitreoretinopathy involves various conditions of retinal detachment complicated by vitreous fibrosis, which, after vitrectomy, may be treated with intraocular injection of fluids that support the retina against the choroid. For conditions requiring a long-term implant, silicone oil although controversial is the material of choice. Many other substances have been investigated but none better has yet been found.
