The use of intraoperative angioscopy, till now utilized exclusively in arterial surgery, is now used also in venous surgery. From January 1992 54 patients underwent to video-guided venous surgery: 23 cases of external valvuloplasty of the sapheno-femoral junction (EV-SFJ), 25 cases of hemodynamic correction of varicose veins (French acronyms CHIVA), 5 cases of high ligation plus long saphenous vein intraoperative sclerotherapy (HL-IS) 1 case of sub-fascial perforators interruption (SPI), the only extraluminal videoguided procedure. We have used 3 different video-angioscopes: a 1 mm monofibroscopy let in a 6 Fr Fogarty catheter, a disposable 2,8 mm colangioscope and a 2,2 mm operative angioscope. For the perforators interruption we have utilised the thoracoscope. EV-SFJ: the angioscopy has confirmed the presence of normal valvular cusps in a dilated vein wall in 21 cases, so excluding 2 patients from the planned treatment. At the end of the operation the angioscope has verified the reapproach of valvular cusps. CHIVA: the angioscopy has allowed to identify the exact points of the superficial venous system which should be interrupted, according to the Franceschi's theory. This procedure can avoid the technical errors due to intraoperatory misleadings of the duplex mapping. HL-IS: consists of a classic high ligation followed by long saphenous vein intraoperative sclerotherapy. The angioscopy has allowed a complete deconnection of the long saphenous vein from tributaries and perforators. Furthermore has facilitate the proportional distribution of the sclerosing agent along the long saphenous vein. SPI: the videoassistance have permitted the identification of the insufficient perforating veins reducing their surgical exposures.(ABSTRACT TRUNCATED AT 250 WORDS)

Background: BEST-CLI established the superiority of single-segment great saphenous vein (ssGSV) conduits for revascularization in patients with CLTI; however, the generalizability of these data is unknown. Thus, we aimed to validate the long-term results of open surgical bypass (BPG) versus angioplasty with or without stenting (PTA/S) using the BEST-CLI inclusion and randomization criteria.
Methods: All patients undergoing a first-time lower extremity revascularization for CLTI at our institution from 2005 to 2022 were retrospectively reviewed.

Objective: Superior vena cava syndrome (SVC) is a debilitating disease, and surgical reconstruction has been described with some of the best results using spiral great saphenous vein (SGSV) grafts. SGSV grafts can be difficult to construct, and a long segment of saphenous vein is needed. Femoral vein has been an excellent conduit for infected aortic and peripheral reconstructions in our hands, and we sought to review outcomes using this conduit for SVC reconstruction.

The Arc of Bühler (AoB) is a rare anatomical variant in gastrointestinal vasculature where there is an aberrant anastomotic vessel between coeliac and superior mesenteric arteries. We present a rare case where AoB was noted intraoperatively to have haemodynamically significant flow in the context of coeliac artery stenosis, supplementing arterial supply to the hepatic artery proper via the gastroduodenal artery (GDA). An interpositional jump graft between the aorta and the GDA stump was created using the long saphenous vein, and flow was restored.

The saphenous vein graft (SVG) has been a cornerstone of coronary bypass surgery, but its long-term patency is limited by accelerated atherosclerosis. Recent advancements, including the no-touch technique and the use of SVG as a limb of the left internal thoracic artery (LITA), have shown promise in improving outcomes. Both approaches enhance nitric oxide (NO) availability, a key factor in promoting endothelial stability and arterial-like behavior in the SVG.

The great saphenous vein (GSV) has long been recognized as the best conduit for vascular bypass procedures. Concomitant varicose veins disease may be a reason for GSV unavailability either due to dilatation and tortuosity of the vein or due to its destruction during invasive venous treatment. -to assess the rate of varicose vein patients with concomitant lower extremity arterial disease (LEAD) who have previously lost their GSV due to venous ablation.
