Synonyms in a broader sense Wegener’s disease, allergic angiitis and granulomatosis, Klinger-Wegener-Churg syndrome, Wegener’s granulomatosis, Wegener-Klinger-Churg giant cell granuloarteritis, rhinogenic granulomatosis Definition Wegner’s granulomatosis is a disease in which the small blood vessels become inflamed throughout the body (systemic vasculitis). This leads to the formation of tissue nodules (granulomas). Mostly the ears, airways, lungs and … Wegener’s granulomatosis
Therapy At the beginning of Wegener’s granulomatosis the antibiotic Clotrimazol (broad-spectrum antibiotics with the ingredients: Trimethroprim and Sulfamethoxazole), e.g. available as Cotrim®, which leads to an improvement, although the mode of action is still completely unclear. In the further course of the disease, treatment is usually with cortisone (trade names e.g. Prednisolon®, Prednihexal®, Decortin®). This … Therapy | Wegener’s granulomatosis
Complications Wegner’s granulomatosis can lead to permanent damage, such as hearing loss, unilateral blindness, limited kidney function. It can also lead to changes in the shape of the nose due to the frequent inflammations and thus to the formation of a saddle nose.

Introduction The term venule refers to a section of blood vessels in the body’s vascular system which, together with the arterioles and capillaries, form the final flow path of the vascular system. The function of the venule includes the exchange between blood and tissue and the transport of blood as part of the vascular system. … Venole
Difference between a venule and an arteriole An arteriole is also a component of the final flow path of the vascular system and resembles an artery in its wall structure. The arteries generally have a larger and more compact muscle layer than the veins. The arterioles form the resistance vessels in the body’s circulation and … Difference between a venule and an arteriole | Venole
