[Management of venous aneurysms and the vascular surgical treatment options : Selection of representative case constellations illustrating experiences at a center for vascular surgery].

Introduction: Venous aneurysms are a rare entity in vascular surgery, which are mostly described in individual case series and meta-analyses generated from them. The treatment concepts are diverse and surgical treatment is highlighted due to the risk of thrombosis and pulmonary embolism. There is still an ongoing debate regarding the postoperative necessity and duration of anticoagulation.

[Trauma-associated vascular injuries and the vascular surgical/interventional options for vascular reconstruction].

Aim: The aim of this work is to illustrate the diversity of vascular injuries in terms of vascular segments or body regions, accident mechanisms and specific patient constellations.

Method: A representative case collection was compiled based on current and relevant scientific references in PubMed, own clinical experiences, vascular surgical and novel image-guided interventional options.

Results: The diagnostics of vascular injuries in the context of trauma and fractures are based on a thorough physical examination.

Evaluation of brain metastasis edema in breast cancer patients as a marker for Ki-67 and cell count-A single center analysis.

Background: Peritumoral edema is an important cause of morbidity and mortality in patients with breast cancer brain metastases (BCBM). The relationship between vasogenic edema and proliferation indices or cell density in BCBM remains poorly understood.

Purpose: To assess the association between tumor volume and peritumoral edema volume and histopathological and immunohistochemical parameters in BCBM.
