Infrequent early recanalization of greater saphenous vein after endovenous laser treatment
2003
Abstract Objective The frequency of recanalization of the greater saphenous vein (GSV) after endovenous laser treatment (ELT) is unclear. This study was undertaken to establish the incidence of early recanalization after ELT and to study the histopathologic features of reperfused and excised GSV. Methods One hundred nine GSV in 85 consecutive patients with clinical stage C 2-6 E P,S A S,P,D P R disease were treated with ELT. Twelve months of follow-up with duplex scanning at regular intervals was possible in 104 treated veins (95.4%) in 82 patients (96.5%). Recanalized vessels were removed surgically and examined at histopathology. Results ELT-induced occlusion proved permanent at duplex sc…
Infrapopliteal Composite Bypass with Autologous Vein and Second Generation Glutaraldehyde Stabilized Human Umbilical Vein (HUV) for Critical Lower Li…

Objective. To audit a single center consecutive series of infrapopliteal composite bypasses with second generation glutaraldehyde stabilized human umbilical vein. Design. Retrospective study. Patients. From January 1996 to July 2006 89 femoro-distal bypasses were constructed in 85 patients with HUV and residual vein segments as composite grafts in the absence of sufficient length of autologous vein. Methods. All patients with infrainguinal bypass operations were registered prospectively. Bypasses to infrapopliteal arteries performed with HUV-composite grafts were reviewed for graft patency, limb salvage, patient survival and possible biodegeneration of the HUV. Results. Early graft thrombos…
Initial experience with a new method of external polyester scaffolding for infrainguinal vein grafts.
2009
Abstract Objectives This study aims to evaluate the feasibility of external polyester scaffolding in infrainguinal bypass grafting when available vein material is suboptimal due to varicosity or dilatation. Primary objectives were short-term primary patency, assisted primary patency and secondary patency. Secondary objectives were to assess the rate of graft stenoses, infections and other adverse effects related to the use of external scaffolding. Materials and methods A total of 50 consecutive patients were included in this prospective, multicentre, feasibility study from six centres. The indication for infrainguinal bypass was critical limb ischaemia (64%), severe claudication (34%) or po…
Endovenous treatment of the greater saphenous vein with a 940-nm diode laser: thrombotic occlusion after endoluminal thermal damage by laser-generate…
2002
Abstract Purpose: Despite a rapid spread of the technique, very little is known about the laser-tissue interaction in endovenous laser treatment (EVLT). We evaluated EVLT of the incompetent greater saphenous vein (GSV) for efficacy, treatment-related adverse effects, and putative mechanisms of action. Methods: Twenty-six patients with 31 limbs of clinical stages C 2-6 , E P , A S,P , P R with incompetent GSV proven by means of duplex scanning were selected for EVLT in an outpatient setting. A 600-μm fiber was entered into the GSV via an 18-gauge needle below the knee and proceeded to the saphenofemoral junction (SFJ). After infiltration of tumescent local anesthesia, multiple laser pulses o…
INFLUENZA DELL’ATEROSCLEROSI CAROTIDEA PRECLINICA SUGLI EVENTI CEREBRO- E CARDIOVASCOLARI IN 5 ANNI DI FOLLOW-UP. INFLUENCE OF PRECLINICAL CAROTID AT…
2009
Introduzione: numerosi studi hanno utilizzato la valutazione dello spessore intima-media carotideo (IMT) come marker di aterosclerosi (ATS) preclinica ed è stato ampiamente dimostrato che l’IMT correla con la presenza di ATS coronarica ed è predittivo di eventi sia cardio- che cerebrovascolari. Scopo dello studio: valutare se in soggetti asintomatici la presenza di ATS carotidea preclinica, ispessimento medio intimale carotideo (IMT) e placca carotidea asintomatica (PCA), aggiunga ulteriori informazioni nella stratificazione del rischio permettendo di individuare soggetti che potrebbero beneficiare di un trattamento più aggressivo, anche farmacologico, dei fattori di rischio presenti.
