The "neurologic hypothesis": A new concept in the pathogenesis of the endometriosis?
2005
To cartograph the retroperitoneal infiltration of deep-infiltrating endometriosis of the rectovaginal space, we report on 467 patients who underwent laparoscopic/vaginal surgery for deep-infiltrating adenomyosis of the rectovaginal space. Exact localisation of the locoregional extension and of secondary infiltrating localisation where noted. The cervix and the rectovaginal ligament were mostly involved, while isolated lesions of the rectovaginal space were very rare. Comparisons of the most involved sites show an absolute correlation with the anatomical repartition of the pelvic sympathetic nervous system. We postulate a new "neurologic theory" which could be one more explanation for the de…
Intravascular Ultrasound-based Imaging Modalities for Tissue Characterisation
2014
Atherosclerosis is the leading cause of cardiovascular mortality and morbidity in the developed world. Intravascular ultrasound (IVUS) is a widely used imaging modality providing complementary diagnostic information to angiography regarding the vessel wall of the coronary arteries. IVUS has been used for assessment of ambiguous angiographic lesions, evaluation of new interventional devices and in atherosclerosis progression-regression trials. However, the standard gray-scale IVUS has limited value for the accurate identification of specific plaque components. This limitation has been partially over- come by introduction of new IVUS-based imaging methods such as: virtual histology IVUS, iMAP…
Das Pulmonalarteriensarkom - Prä- und postoperative radiologische Befunde bei der Tumorerstmanifestation und beim Rezidiv
2008
Purpose Primary pulmonary artery sarcomas are very rare tumors. Their diagnosis is difficult due to their unspecific symptoms. Still, an early preoperative diagnosis is the only possibility for a potential therapy. Patients and methods 4 pre- and 5 postoperative CT- and three pre- and one postoperative MRT-examination(s) have been evaluated with respect to surgical and histological findings. Results The presence of a convex intraluminal bulging mass spreading mostly from the pulmonary trunc continuously into the peripheral pulmonary artery branches the filling and dilatation of the vessels, the tumor's inhomogeneity indicating hemorrhages and necrosis and the appearance of intrapulmonary no…
A Bifurcation with Surprise
2016
FFR was assessed after provisional stenting of a bifurcation stenosis in the proximal LAD in a very young patient. Pull-back demonstrated a good outcome after PCI, and it revealed the existence of an additional stenosis which, due to its very proximal location in the LAD, could not be seen at angiography. This case emphasizes the importance of performing FFR measurements during sustained hyperemia and using a slow pull-back technique.
Angiographic follow-up results of a randomized study on angioplasty versus bypass surgery (GABI Trial)
1996
Although several randomized trials have been performed to compare the outcomes of percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass surgery (CABG) in patients with multivessel disease, there is little data available on angiographic follow-up results. The present substudy of the German angioplasty versus bypass surgery investigation (GABI Trial) compares the angiographic revascularization status in these two cases 6 months after treatment. Follow-up angiograms were available in 102 CABG patients and 117 PTCA patients. Although the protocol excluded patients with total occlusion, on follow-up 6 months after treatment we found total occlusion of 94 native arterie…
Klassifikation und Therapie von Endolecks nach endovaskulärer Behandlung von abdominellen Aortenaneurysmen
2005
This article describes the classification of endoleaks after endovascular treatment of abdominal aortic aneurysms, thereby summarizing the most important problems of this endovascular technique. The correct classification of endoleaks is a prerequisite for interdisciplinary discussion. It is indispensable for professional reporting of the pathological findings and for the decision making as to the adequate treatment of endoleaks. Irrespective of the types of stent graft and property of the material, five endoleak types are defined in the literature: leakage at the anchor sites (type I); leakage due to collateral arteries (type II); defective stent grafts (type III); leakage due to porosity …
Minimally invasive techniques in the treatment of saphenous varicose veins.
2008
Lower extremity venous insufficiency is common and increases with age. In addition to classical symptoms, it may result in skin changes and venous ulcers. Chronic venous insufficiency has a great impact on patients' health-related quality of life and is associated with considerable health care costs. Surgical ligation Of the junction with or without stripping has been the standard of care in the treatment of insufficient great and small saphenous veins. However, the recurrence rates are relatively high and surgery may be associated with serious adverse events and considerable down time; it is also cosmetically Suboptimal. To improve efficacy, patients' health-related quality of life and tre…
Maintenance therapy in gastro-oesophageal reflux disease.
2005
Gastro-oesophageal reflux disease (GORD) is a chronic condition. Symptom control and the maintenance of healing of erosive oesophagitis, if present, are important topics. In patients responding to a proton pump inhibitor (PPI) and showing no treatment symptoms it is appropriate to consider long-term treatment strategies, whether continuous, intermittent or on demand. Maintenance PPI therapy is well tolerated for up to 10 years of continuous use. Furthermore, tachyphylaxis does not occur during long-term maintenance PPI therapy. Previous concerns about risks of long-term PPI therapy in Heliobacter pylori-negative or H. pylori-positive patients have not materialized, while no cases of intesti…

Tutorial in oral antithrombotic therapy: biology and dental implications.
2013
Objectives: Recent developments of new direct oral anticoagulants that target specific clotting factors necessitate understanding of coagulation biology. The objective of this tutorial is to offer dental professionals a review of coagulation mechanisms and the pharmacodynamics of the conventional and new oral anticoagulants. Also, we summarized the dental implications of the conventional and new anticoagulants. Method: We searched Medline using search terms “antithrombotic”, “antihemostasis” or “anticoagulation” and combined them with the search results of “dental”, “oral surgery” or “periodontal”. We restricted the results to “human” and “English”. Results: The early coagulation cascade, t…
