who had a double lumen endotracheal tube to allow both sides to be operated on at the same operation, which lead to hypoxia of the brain. Our experience is to use a similar endotracheal anaesthesia and but to only to perform this operation on one side at a time. As well as reducing the possible anaesthetic risk also allows the patients to experience any side effects especially the compensatory sweating. If this is troublesome then the patient may have no wish to have the other side done. A. Tiwari, A.M.S. Abeysekara, J.B. Coker, S.

Current Treatment Options for Treating Primary Hyperhidrosis We read with interest the comprehensive review article by Nyamekye.1 Some of the complications of treating hyperhidrosis using endoscopic thoracic sympathectomy, however, have not been fully discussed. In a recent review article by Ojimba and Cameron,2 significant complications of this procedure highlighted include death, (though as highlighted by the author never actually reported in the literature), bleeding, neuralgia and rebound sweating. The other problem, which has been highlighted is compensatory sweating which the authors have reported is probably more prevalent than actually reported. The patients who died from anaesthetic complication were those * In order to avoid possible confusion between the terminology used by the Authors and that suggested in #7, in this letter, the veins of the lower limb are designated with the original Latin terms.

I read with great interest the article from Dr MacKenzie and coll. entitled ‘The effect of Long Saphenous Vein stripping on deep venous reflux’ (EJVES 2004; 28: 104–107) which confirms that radical surgery of varicose veins enhance deep veins hemodynamics. The authors evaluated deep venous hemodynamics at the thigh by insonating only the Vena Femoralis.* Their findings would be further enhanced by extending Duplex evaluation to the Vena Femoralis Communis, due to its closer hemodynamic interdependency with of the proximal Vena Saphena Magna.1 The authors reported a ‘surprisingly common failure to obtain complete stripping’ of the Vena Saphena Magna after its stripping to the knee. In 62% of limbs, the postoperative Duplex demonstrated remnants of various length ‘.of the Vena Saphena Magna removed in the thigh’. This intriguing and apparently paradoxical finding could be explained by the particular anatomy of thigh superficial veins.

Sherman3 and Haeger,4 demonstrated that one or even two large superficial veins may ascend parallel to the Vena Saphena Magna. A ‘double or triple saphenous system’ was firstly demonstrated by Leonardo da Vinci5 and it occurs in about one half of limbs (45–62%) evaluated by venography5 and sonography.6 These parallel veins are called ‘Accessories of the Vena Saphena Magna’ and designated on the basis of their topography in Anterior, Posterior or Superficial.7 Duplex can easily discriminate these veins from the Vena Saphena Magna because they course out of the Saphenous Compartment, in a more superficial plane of the subcutaneous tissue.8,9 In varicose limbs, the reflux may descend along the Vena Saphena Magna, along an accessory vein or both.9 But, the stripper strips only the vein in which it courses and the other automatically becomes a ‘residual’. If varicose, the residual vein benefits from surgery only when this abolishes the reflux or induces its thrombosis. If the residual vein will recanalize, it will look like a ‘remnant’. If a new reflux will develop (from the saphenic stump, from pelvic veins or from a perforator), it will descend along the residual vein to possibly nourish leg varicosities. Thanks to the different planar anatomy and fascial relationships,7 Duplex can discriminate the leg Vena Saphena Magna from its accessories, which are more frequently afflicted with varicose changes.10 The ‘.high incidence of below-knee reflux after stripping of the Vena Saphena Magna to the knee.’ probably concerns saphenous accessories and tributaries, because at the leg, the Vena Saphena Magna is rich of valves and well protected by the Saphenous Fascia against varicose changes.8 Concluding, I strongly agree with the authors

convincement that ‘this study reinforces routine preoperative duplex’. But this must take into account the clear anatomical and topographical differences between saphenous trunks and accessories. A. Caggiati Department of Anatomy, University ‘La Sapienza’, Rome, Italy
