Abstract
PURPOSE To evaluate the safety and technical success of the AndraValvulotome™ device (Andramed GmbH, Reutlingen, Germany) in patients with peripheral arterial disease (PAD) requiring bypass surgery using the great saphenous vein (GSV) as graft. METHODS This was a multicenter, post-market observational study conducted in 2021 in 11 German centers. Safety and efficacy data were prospectively collected and analyzed. Primary endpoints were the absence of device-related serious adverse events until 30 ± 7 days follow-up, the clinical efficacy of valvulotomy, which was defined as pulsatile blood flow in the bypass and the number of insufficiently destroyed vein valves. Secondary endpoints were the number of valvulotomy passages, the primary patency rate of the venous bypass (determined by a color-duplex sonography showing a normal blood flow through the bypass and absence of stenosis or occlusion), and the primary technical success defined as the absence of product-specific (serious) adverse events and clinical efficacy. RESULTS Fifty-nine patients were enrolled. The mean age of the patients was 71 years (46-91), and 74.6% were males. The vein material used for bypass grafting had a median length of 47.5 cm (range 20-70 cm) with a median diameter of 5.0 mm (range 3-6 mm) and 4.0 mm (range 2-6 mm) in the proximal and distal segments, respectively. The technical success rate was 96.6%. The primary patency rate was 89.9% at 30 days follow-up. The clinical efficacy was rated as very good in 81% of patients, fair in 17%, and poor in 2%. Between 1 and 5 (average 2.9) valvulotome passages were performed. One product-related serious adverse event was recorded (bypass vein dissection). CONCLUSION The AndraValvulotome™ can be considered a safe and effective device to disrupt venous valves during in situ non-reversed bypass surgeries using GSV grafts in patients with PAD.

Abstract
BACKGROUND In this study, the early and mid-term outcomes of the use of the Mills valvulotome in patients with chronic limb-threatening ischemia (CLTI) undergoing infrainguinal in-situ saphenous vein bypass were investigated. METHODS From January 2018 until December 2019, 153 consecutive CLTI patients from 7 centers have been treated with infrainguinal in-situ saphenous vein bypass. In all patients the devalvulation of the great saphenous vein (GSV) was obtained with the use of the HYDRO LeMaitre® valvulotome (LeMaitre Vascular, Burlington, MA, USA). Eighty-six patients (56.2%) received the additional treatment of the LeMills valvulotome (LeMaitre Vascular) to disrupt the distal valves of the GSV (Group MV), whilst in the remaining 67 patients (43.8%) this adjunctive device was not used (Group no-MV). Initial outcome measures including intraoperative vein injuries were assessed and compared. At 2-year follow-up, estimated outcomes of primary patency, primary assisted patency, secondary patency, freedom from distal vein restenosis, and limb salvage were analyzed using Kaplan-Meier curves and compared between groups using the log-rank test. RESULTS Intraoperatively, the overall rate of vein injuries related to the devalvulation was 5.2% (8 cases) with four cases in both groups (4/86, 4.6%, Group MV vs. 4/67, 6%, Group no-MV; P=0.49). Overall, 4 lesions occurred in the distal portion of the GSV and were all reported in Group no-MV (0/86, 0%, Group MV vs. 4/67, 6%, Group no-MV; P=0.03). Median duration of follow-up was 12 months (IQR: 6-24). At 2-year follow-up there were no differences between the two groups in terms of primary patency (69.9% Group MV vs. 79.8% Group no-MV, P=0.08), primary assisted patency (85.4% Group MV vs. 90.5% Group no-MV, P=0.37), secondary patency (94.2% Group MV vs. 92.1% Group no-MV, P=0.61), and limb salvage (97.4% Group MV vs. 98.2% Group no-MV, P=0.74). Patients in Group MV had a higher rate of freedom from distal vein restenosis (92.2% Group MV vs. 76% Group no-MV, P=0.03). CONCLUSIONS Adjunctive use of the Mills valvulotome (LeMaitre Vascular) reduces intraoperative distal vein injuries and improves the 2-year freedom from distal vein restenosis in patients undergoing infrainguinal in-situ saphenous vein bypass.

Abstract
BACKGROUND Modality of elective repair (open or endovascular) of popliteal artery aneurysms (PAAs) is still debated. About open repair no strict evidence exists about the best surgical technique. The aim of this study was to report a 20-year experience with ligation and in situ saphenous vein bypass for the elective treatment of PAAs. METHODS A retrospective review of consecutive patients who underwent elective open surgical PAA repair in our center between January 2001 and April 2020 was performed. Ninety-two limbs in 84 patients underwent a PAA ligation and in situ saphenous bypass. Early (30 day) outcomes were assessed. Estimated 5-year outcomes according to Kaplan-Meier curves in terms of primary patency, primary assisted patency, secondary patency, and limb salvage were evaluated. Associations of patient and procedure variables with patency and limb salvage outcomes were sought with multivariate analysis. RESULTS Patients were predominantly male (80/84, 95.2%) with a mean age of 73.1 years (range 50-89). In all cases technical success was obtained. The mean hospital stay was 5.8 days (range 2-27). Thirty-day overall mortality (n=1) and major amputation (n=1) rates were both 1.2%. Mean duration of follow-up was 31.3 months (range 1-168). At 5 years estimated rates of primary patency, primary assisted patency, secondary patency, and limb salvage were 76.3%, 81.5%, 89.9%, and 96.6%, respectively. On multivariate analysis the associations were: primary patency with PAA diameter >30 mm (P=.007), and poor run-off status (P<.001); primary assisted patency with poor run-off status (P<.001); secondary patency with poor run-off status (P=.04). Major amputation had no independent predictors of poor outcomes. CONCLUSIONS Elective surgical treatment of PAAs with ligation and in situ saphenous vein bypass is safe, effective and urable with good 5-year outcomes in terms of overall patency and limb salvage. Poor run-off status seemed to be an independent predictor of worse patency rates. This surgical technique should be cautiously applied in patients with PAAs with a diameter >30 mm.

Limb salvage after aneurysmal degeneration of a cryopreserved vein allograft: Searching the autologous veins of the arm is worth the effort. Morphologie 2020; 104:202-213. [PMID: 32518049 DOI: 10.1016/j.morpho.2020.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 04/29/2020] [Accepted: 05/14/2020] [Indexed: 06/11/2023]
Abstract
CLINICAL DATA We hereby report a case of limb salvage involving a 64-year-old man who was hospitalized with ischemic foot ulcers for two months. Endarterectomy with patching and stenting of the left iliofemoral artery failed. A composite bypass of two segments of the endarterectomized superficial femoral artery and a cryopreserved saphenous vein graft was implanted one week later. On day 4 postoperatively, an infection (Staphylococcus epidermidis and Pseudomonas aeruginosa) was treated empirically with antibiotics. Four months later, the femoro-tibial bypass thrombosed and the patency was restored by thrombolysis. The aneurysmal cryopreserved vein was excised. Iterative complications followed and final success was attained after implantation of autologous cephalic and basilic veins. Four years later, this femoro-tibial is still patent. PATHOLOGICAL ANALYSES After a gross observation, the explant was dissected and the most significant sections were processed for histology, followed by analyses in scanning electron microscopy, light microscopy and transmission electron microscopy. RESULTS The explanted specimen showed a smooth flow surface proximally but a severe distortion distally, with an accumulation of poorly organized mural thrombi. The wall of the arterialized vein was accompanied with an important inflammatory reaction. The degradation of the collagen structure was evidenced in TEM. The fibrils of collagen were still individualized but were fragmented and did not display parallelly. The regular banding was preserved. The presence of Pseudomonas aeruginosa was shown inside the wall of the homologous vein. COMMENTS In case of sepsis, the most aggressive antibiotic treatments cannot fully eliminate the bacteremic colonizations within the wall of an alternative conduit. The cephalic and basilic autologous veins are proved to be preferable in absence of the autologous saphenous vein. The amputation was prevented and four years later the bypass is still patent. This is an outstanding result based upon the comorbidities of the patient. The most aggressive harvesting shall be recommended. This patient represented a considerable challenge and the clinical result is highly gratifying: the search for the autologous cephalic and basilic veins proved to be worth the effort.
