Perforating veins are those which connect the deep veins to the superficial veins. To achieve this they pass through the deep fascia of the calf. Although the sapheno-popliteal junction is a perforating vein, it is not discussed in this section. Anatomical dissections from leg amputations in patients free of venous disease reveal that the perforating… Read More »
The re-appearance or enlargement of residual varicose veins (VVs) may occur after all the different methods of treatment. It is unlikely that any one treatment will ever provide a complete protection against recurrence. This is related to the fact that patients have an inherent weakness in the wall of their veins. Relentless pressure from gravitational… Read More »
Sclerotherapy for telangectasias (spider veins) is a common method of treatment. Duplex ultrasound is usually required beforehand to exclude underlying saphenous reflux because this may be contributory to recurrence. Care in identifying and selecting the feeder vessel prior to cannulation improves the immediate results. Nevertheless, recurrence may result in the need for further treatment. There… Read More »
Cannulation is always painful and uncomfortable to the extent it may result in the development of needle phobias in some patients. Current developments to reduce pain include the application of local anaesthetic cream, smaller needles and nearby pressure to dampen and modulate the pricking sensation. With multiple needle punctures, such as that occurring during phlebectomies… Read More »
Popliteal vein compression (PVC) is rarely considered as a cause of venous obstruction, chronic venous insufficiency or even DVT. Greater awareness of the condition may lead to an improved diagnosis in patients with venous disease. DAVID HUBER This condition is distinct from popliteal vein entrapment. Popliteal vein compression is seen when the knee is extended… Read More »
Foam is usually prepared immediately before injection by agitating a sclerosant with a gas using 2 syringes and a three-way tap. This is described as the Tessari method. A disadvantage of this foam preparation is its lack of stability. This is because, after a few minutes, the bubbles coalesce into larger bubbles which will decrease… Read More »
