A novel technique of percutaneous intraluminal cracking using a puncture needle for severe calcified lesions of below-the-knee and below-the-ankle arteries

SummaryWe present two case reports concerning patients who had to undergone surgical treatment according tp the diagnosis of thrombophlebitis with insufficiency of the greater saphenous vein and putative encapsulated haematoma in the lower left leg area. During the operation we found tumours with urgent suspicion of malignancy. The histological examination revealed the diagnosis of mesenchymal chondrosarcoma and malignant peripheral nerve sheath tumour which are extremely malignant, but very rare neoplasmas with unfavourable prognosis. Conclusion: Since both types of tumours are often located below the knee, phlebotomists and vascular surgeons should take them into account as differential diagnosis.

Additional Value

SummaryThe objectives of this observational study were to investigate whether varicography has additional value to CFDI in clarifying the nature and source of recurrent varicose veins below the knee after varicose vein surgery and to investigate the possible role of incompetent perforating veins (IPV) in these recurrent varicose veins. Patients, material, methods: 24 limbs (21 patients) were included. All patients were assessed by a preoperative clinical examination and CFDI (colour flow duplex imaging). Re-evaluation (clinical and CFDI) was done two years after surgery and varicography was performed. Primary endpoint of the study was the varicographic pattern of these visible varicose veins. Secondary endpoint was the connection between these varicose veins and incompetent perforating veins. Results: In 18 limbs (75%) the varicose veins were part of a network, in six limbs (25%) the varicose vein appeared to be a solitary vein. In three limbs (12.5%) an incompetent sapheno-femoral junction was found on CFDI and on varicography in the same patients. In 10 limbs (41%) the varicose veins showed a connection with the persistent below knee GSV on varicography. In nine of these 10 limbs CFDI also showed reflux of this below knee GSV. In four limbs (16%) the varicose veins showed a connection with the small saphenous vein (SSV). In three limbs this reflux was dtected with CFDI after surgery. An IPV was found to be the proximal point of the varicose vein in six limbs (25%) and half of these IPV were detected with CFDI as well. Conclusion: Varicography has less value than CFDI in detecting the source of reflux in patients with recurrent varicose veins after surgery, except in a few cases where IPV are suspected to play a role and CFDI is unable to detect these IPV.

The Media

SummaryA modification of the fibrin slide method of Todd permitting a semiquantitative estimation of the fibrinolytic activity in tissue sections is described. By means of this technique, the authors have studied the fibrinolytic activity of the great saphenous vein and of superficial veins of the arm and leg in patients suffering from varices and in normal subjects. It was found that:1. Fibrinolytic activity is localized, in these vessels, mainly to the vasa vasorum of the adventitia. The media is moderately active. Intimal cells are active only when detached.2. The great saphenous vein is more active above than below the knee.3. The veins of the arm are definitely more active than the veins of the leg.4. The activator of plasminogen demonstrated in the sections by the fibrin slide method is a fairly stable enzyme still active after exposure to 60° C and resistent to moderate variations of pH.
