ABSTRACT
OBJECTIVE: The aim of this retrospective study was to assess the long-term results of stripping the insufficient great saphenous vein (GSV) with stump coagulation, closure of the cribriform fascia and some additional measures, which will be described in detail. METHODS: Patients treated from 1998 to 1999 for varicose veins had been invited in 2009 for follow-up colour-coded duplex sonography and had been asked to answer a quality-of-life questionnaire. In 2009, the examinations for the study were conducted at a clinic of angiology by an independent and experienced sonographer. RESULTS: From a total of 165 patients, 91 (136 limbs) had been willing to participate in the study. Duplex ultrasound after a mean follow-up of 10.7 years revealed only clinically non-relevant (∅ < 0.3 cm) neovascularizations in 1.5% of all treated legs. No clinical relevant varicosities from the groin had developed. CONCLUSION: The crossectomy combined with stump coagulation and suture of the fossa ovalis, completed with some additional measures, is a successful method to reduce neovascularization and recurrent varicosities, even for redo-crossectomies, without increasing the risk of perioperative complications.

We discuss the dynamic behavior of a tagged particle close to a classical localization transition in the framework of the mode-coupling theory of the glass transition. Asymptotic results are derived for the order parameter as well as the dynamic correlation functions and the mean-squared displacement close to the transition. The influence of an infrared cutoff is discussed.
ABSTRACT
Peripheral atherosclerotic vascular disease is associated in up to 12% with an abdominal aortic aneurysm (AAA). If operation is required AAA is treated in 90% by infrarenal dacron graft implantation. As late complication secondary aortoduodenal fistula is diagnosed in 0.1-4.0%. Mortality in untreated patients is 100%, perioperative mortality depending on operative technique is 17-77%. We present 2 case reports and diagnostic, operative and prophylactic methods.
