Angioscopy-guided semiclosed technique for in situ bypass with a novel flushing valvulotome: early results.

To allow and facilitate endoluminal vein preparation under angioscopic guidance for in situ bypass grafting, a Mill's valvulotome was equipped with a flushing channel. The advantages of the novel valvulotome are obvious: it allows perfect angioscopic view within a saphenous vein that still contained blood by adjusting the jet of lactated Ringer's solution directly to the lens of the angioscope; it permits the use of very small angioscopes without integrated flushing channels, preventing endothelial damage. The described technique was tested in 27 peripheral reconstructions in 26 patients. The secondary cumulative patency rate within a follow-up time of 4 to 30 months (mean, 14 months) was 89%. The described technique substantially facilitates in situ bypass grafting and minimizes early and late complications and further improves surgical outcome.

[Angioscopy and the surgical treatment of varices in the area of the external saphenous vein].

The study of post-surgical relapses, by ultrasound and phlebographic examinations, shows that the difficulties in the treatment of varices of the external saphena territory are of two types: anatomical and haemodynamic. The venous endoscopy answers precisely to the requirements of the surgical treatment of varices of the popliteal space. It offers an acceptable compromise between aesthetics and efficacy, thanks to the incisions centred on the transcutaneous luminal point. It enables a per-operative control of the ultrasound-Doppler marking and the visualization of the small calibre perforating veins (less than 2 mm), not visible by ultrasound. It especially locates the deep non palpable refluxes situated above the anastomosis of the external saphenofemoral junction. The technique used is very simple thanks to the miniaturization of the equipment and the use of flexible small calibre endoscopes adapted to venous explorations.
