Deep venous thrombosis (DVT) and varicosis are common diseases of veins. Blood flow analysis und morphologic parameters are the basis in the diagnosis of varicosis. Ultrasound is the preferred method in the diagnosis of varicosis. However, also today, phlebography is an important diagnostic tool. Venous anomalies are another topic covered in the second part of this review. Primary venous tumors are rare. Computed tomography and magnetic resonance imaging (MRI) are the preferred methods to demonstrate the origin and extent of this disease.

Vasculopathy is a rare and undervalued complication in neurofibromatosis. Histopathological changes of the vascular wall may lead to relevant renal artery stenosis. We report a case of a 17-year-old patient with neurofibromatosis and severe renovascular hypertension resulting from a proximal renal artery stenosis. Attempted percutaneous renal angioplasty was unsuccessful and the patient was referred for operative revascularization. After insertion of an aortorenal bypass with a reversed saphenous vein graft the patient became normotensive without medication. Based on our own experience and a review of the literature we recommend operative reconstruction of stenotic renal arteries in neurofibromatosis.
