Ann Vasc Surg 2024; 103:133-140. [PMID: 38428452 DOI: 10.1016/j.avsg.2023.12.067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 10/29/2023] [Accepted: 12/10/2023] [Indexed: 03/03/2024]
Abstract
BACKGROUND Alternative autologous veins can be used as a conduit when adequate great saphenous vein is unavailable. We analyzed the results of our infrainguinal bypasses after adopting upper extremity veins in our practice. METHODS This is a single-center observational study involving all patients whose infrainguinal bypass involved the use of upper extremity veins between April 2019, when we began using arm veins, and February 2023. RESULTS During the study period, 49 bypasses were done in 48 patients; mean age 68.1 ± 9.8; men 32 (66.7%); body mass index 28.0 ± 4.8; indications for surgery: chronic limb threatening ischemia 41 (83.7%); acute limb ischemia 3 (6.1%); complications of previous prosthetic 3 (6.1%), or autologous 2 (4.1%) bypass grafts. Vein splicing was used in 43 (87.8%) bypasses with 3-segment grafts being the most common (26; 53.1%). There were 24 (49.0%) femorotibial, 11 (22.4%) femoropopliteal, 9 (18.4%) femoropedal, and 5 (10.2%) extension jump bypass procedures. Eighteen (36.7%) operations were redo surgeries. Twenty-one (42.9%) bypasses were formed using only arm veins. The median follow-up was 12.9 months (4.5-24.2). Two bypasses occluded during the first 30 postoperative days (2/49; 4.1%). Overall 30-day, 1-year, and 2-year primary patency rates were 93.7% ± 3.5%, 84.8% ± 5.9%, and 80.6% ± 6.9%, and secondary patency (SP) rates were 95.8% ± 2.9%, 89.2% ± 5.3%, and 89.2% ± 5.3%. One-segment grafts had better patencies than 2-, 3-, and 4-segment grafts (1-year SP 100% ± 0% vs 87.6% ± 6.0%). Two-year amputation-free survival was 86.8% ± 6.5%; 2-year overall survival was 88.2% ± 6.6%. CONCLUSIONS Integration of arm vein grafts in infrainguinal bypass practice can be done safely with low incidences of perioperative graft failure. One-segment grafts had better patencies than spliced vein grafts. The achieved early patency and amputation-free survival rates strongly encourage their use. In the absence of a single-segment great saphenous vein, upper extremity vein grafts should be the preferred conduit choice.

Abstract
BACKGROUND In this study, the early and mid-term outcomes of Omniflow® II (LeMaitre Vascular, Inc., Burlington, MA, USA) biosynthetic graft in redo surgery in patients with critical limb-threatening ischemia (CLTI) with no available autologous vein material were investigated with the aim to compare the outcomes obtained in "de novo" surgery versus redo surgery. METHODS From January 2018 until December 2022, data of CLTI patients from 18 centers in Italy with no autologous vein material underwent infrainguinal bypass with Omniflow® II biosynthetic graft were collected. Thirty-day outcome measures including intraoperative technical success, major morbidity, mortality, and graft patency were assessed and compared. At two-year follow-up, estimated outcomes of survival, primary patency, primary assisted patency, secondary patency, freedom from reintervention, and amputation-free survival were analyzed using Kaplan-Meier curves and compared between groups using the log-rank test. RESULTS In the study period 119 CLTI patients had an infrainguinal bypass with Omniflow® II biosynthetic graft. Seventy-seven patients (64.7%) underwent bypass as "de novo" treatment (group de novo), whilst in the remaining 42 patients (35.3%) the procedure was performed as redo surgery due to occlusion and/or infection of a previous bypass graft (group redo). Two groups were homogeneous in terms of demographic, clinical, and morphological data. In group redo explantation of an infected prosthetic graft was needed in 4 cases (9.5%). Intraoperative technical success was achieved in all cases in both groups. At 30 days, the overall patency rate did not differ between the two groups (69/77, 89.6%, group de novo vs. 35/42, 83.3%, group redo; P=0.24), whilst in group redo limb loss was higher with a statistically significant different 30-day major amputation rate between the two groups (11.9% group redo vs. 1.3% group de novo; P<0.001). Overall median duration of follow-up was eight months (IQR 6-13). At two-year follow-up there were no differences between the two groups in terms of survival (67.7% group de novo vs. 55.8% group redo, P=0.53), primary patency (34.4% group de novo vs. 26.8% group redo, P=0.25), primary assisted patency (43.6% group de novo vs. 28.8% group redo, P=0.12), freedom from reintervention (64.1% group de novo vs. 68.8% group redo, P=0.98), and amputation-free survival (67.8% group de novo vs. 60% group redo, P=0.12). Secondary patency was significantly higher in group de novo (53.7% vs. 32.3%, P=0.05). During the follow-up, the overall rates of graft infection and aneurysmal degeneration were 3.4%, and 0.8%, respectively. CONCLUSIONS Nevertheless, poorer early outcomes in terms of limb salvage, Omniflow® II biosynthetic graft offers acceptable ywo-year outcomes in redo surgery in CLTI patients with no available autologous vein material. Further studies with larger population sizes are needed to validate these outcomes.

Ann Vasc Surg 2024; 98:124-130. [PMID: 37858670 DOI: 10.1016/j.avsg.2023.08.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 08/25/2023] [Accepted: 08/26/2023] [Indexed: 10/21/2023]
Abstract
BACKGROUND Single segment, greater saphenous vein (GSV) conduit is considered the optimal bypass conduit among patients undergoing bypass surgery for peripheral artery disease (PAD). While this data has been extrapolated to patients undergoing bypass for popliteal artery aneurysms (PAAs), the pathophysiology of PAA is inherently different when compared to PAD, and the impact of conduit type on long-term outcomes after open repair of PAA remains unclear. METHODS A multicenter database of five regional hospitals was retrospectively reviewed for all patients with PAA undergoing open surgical repair. Data were collected on demographic information, operative details, medications, and postoperative outcomes. Kaplan-Meier curves were used to compare freedom from major adverse limb events (MALE) following GSV versus prosthetic bypass. Cox proportional hazards model was used to identify patient-level characteristics associated with MALE, which was defined as major ipsilateral limb amputation or reintervention for graft patency. RESULTS From 1999 to 2020, a total of 101 patients with PAA underwent open exclusion and bypass surgery. Median follow-up period was 4.2 years (interquartile range, 1.3-7.4 years), and complete data were available for 99 (98.0%) patients. The majority of patients were male (99.0%) and Caucasian (93.9%). Only 11.1% of procedures were emergent, with the remainder (88.9%) being elective. All patients underwent medial exposure with a below-knee popliteal bypass target (100%). Bypass conduits included GSV (69.7%), prosthetic conduit (28.3%), and 2 (2.0%) alternative conduits (one spliced arm vein, one cryopreserved vein). Patients undergoing prosthetic bypass were older (72 vs. 66 years, P = 0.001) and had similar rates of medical comorbidities. Compared with the GSV group, patients with prosthetic conduits were more frequently placed on postoperative anticoagulation (60.7% vs. 23.2%, P < 0.001). Conduit type did not impact postoperative complication rates (P = NS each). MALE rates were low overall (19.2% at 2 years), and similar when stratified by conduit type (log rank P = 0.47). On multivariable analysis, emergent bypass was associated with MALE (hazard ratio [HR] 5.73, 95% confidence interval [CI] 2.07-15.85, P < 0.001). Prosthetic conduit usage (HR 1.00, 95% CI, 0.40-2.51, P = 0.99) and postoperative anticoagulation (HR 1.02, 95% CI 0.42-2.50, P = 0.97) were not associated with MALE. CONCLUSIONS Open repair of PAA is associated with excellent long-term outcomes. Prosthetic bypass is a comparable alternative to autogenous conduit for below-knee popliteal bypass targets, and lack of suitable GSV should not prohibit open surgical repair when indicated.

Abstract
Objective: Due to the potential of thrombus blockage and aneurysm rupture, saphenous veins with varicose veins are not advised for use as bypass grafts. However, if no other autologous vein is accessible for use as a conduit in lower-limb bypass; varicose vein transplants may be employed. Few reports have studied the clinical results of lower-limb bypass using varicose vein grafts. We therefore investigated whether or not acceptable patency rates of varicose vein graft for lower-limb bypass could be achieved. Methods: We performed lower-limb bypass using varicose vein graft on nine limbs from June 2017 to May 2020 and conducted a retrospective analysis of prospectively collected data. Results: Early graft failure following bypass surgery using a varicose vein transplant was not detected, and major complications, such as acute graft occlusion or aneurysm dilatation, were not noted throughout the follow-up period. The primary and secondary patency of varicose vein graft was 70.0% and 100% at 3 years, respectively. Conclusion: The incidence of major problems of the varicose vein transplants does not seem to be higher than with conventional saphenous vein grafts. If there are no other appropriate autologous veins, a varicose vein graft may be useful as a conduit for bypass surgery.

Abstract
INTRODUCTION Despite advances of endovascular interventions, bypass surgery remains the gold standard for treatment of long and complex arterial occlusions in the lower limb. Autologous vein is regarded superior to other options. As the graft of first choice, the great saphenous vein (GSV) is often not available due to previous bypass, stripping or poor quality. Other options like arm veins (AV) are important alternatives. As forearm portions of AVs are often unusable, a graft created from the upper arm basilic and cephalic veins provides a valuable alternative. PATIENTS AND METHODS We analyzed consecutive patients treated at an academic tertiary referral center between 01/1998 and 07/2018 using arm veins as the main peripheral bypass graft. Study endpoints were primary patency, secondary patency, limb salvage and survival. RESULTS In the observed time period 2702 bypass procedures were performed at our institution for below-knee arterial reconstructions. Vein grafts used included the ipsilateral GSV (iGSV; n = 1937/71.7%), contralateral GSV (cGSV; 192/7.1%), small saphenous vein (SSV; 133/4.9%), prosthetic conduits (61/2.3%) and different configurations of AV (379/14%). In the majority of patients receiving AV grafts a complete continuous cephalic or basilic vein (CAV) was used (n = 292/77%). If it was not possible to use major parts of these 2 veins, either spliced arm vein grafts (SAV) (42/11%) or an upper arm basilic-cephalic loop graft (45/12%) were used. Median follow-up was 27 (interquartile range: 8-50) months. After 3 years secondary patency (CAV: 85%; SAV: 62%; loop: 66%; p = 0.125) and limb salvage rates (CAV: 79%, SAV: 68%; loop: 79%; p = 0.346) were similar between the 3 bypass options. CONCLUSION The encouraging results of alternative AV configurations highlight their value in case the basilic or cephalic veins are not useable in continuity. Especially for infragenual redo-bypass procedures, these techniques should be considered to offer patients durable revascularization options.

Abstract
A growing, but poorly defined subset of patients with chronic limb-threatening ischemia (CLTI) have "no option" for revascularization. One notable subgroup includes patients with severe ischemia and advanced pedal artery occlusive disease, termed "desert foot," who are at high risk for major amputation due to a lack of conventional revascularization options. Although new therapies are being developed for no-option patients with desert foot anatomy, this subgroup and the broader group of no-option patients are not well defined, limiting the ability to evaluate outcomes. Based on a systematic review, a classification of the no-option CLTI patient was constructed for use in clinical practice and studies. Several no-option conditions were identified, including type I-severe and pedal occlusive disease (desert foot anatomy) for which there is no accepted method of repair; type II-lack of suitable venous conduit for bypass in the setting of an acceptable target for bypass; type III-extensive tissue loss with exposure of vital structures that renders salvage impossible; type IV-advanced medical comorbidities for which available revascularization options would pose a prohibitive risk; and type V-presence of a nonfunctional limb. While type I and type II patients may have no option for revascularization, type III and type V patients have wounds, infection, comorbidities, or functional status that may leave them with few options for revascularization. As treatment strategies continue to evolve and novel methods of revascularization are developed, the ability to identify no-option patients in a standardized fashion will aid in treatment selection and assessment of outcomes.

Abstract
In this case report, we present a patient scheduled for operation due to critical leg ischemia in whom a bilateral great saphenous vein (GSV) had already been used during previous cardiac and peripheral vascular surgeries. The patient underwent femorofemoral crossover bypass from left to right with a small saphenous vein and right femoropopliteal bypass with cephalic vein (CV) during the same session. Distal pulses became palpable, and symptoms regressed dramatically following the operation. A control computed tomographic angiography scan revealed no signs of graft stenosis 32 months after the surgery. Despite the recent advances in synthetic graft materials, small saphenous and CVs should be remembered as alternative long-standing conduits in the absence of the GSV.

Abstract
BACKGROUND Bypass surgery remains the gold standard for long and complex arterial occlusions in the lower limb. The vein is regarded superior to prosthetic conduits in peripheral arterial bypass surgery. However, this option is often limited because of previous bypass, stripping, or poor quality of the ipsilateral and/or contralateral great saphenous vein (GSV). Under these circumstances, the arm vein (AV) and small saphenous vein (SSV) are the only alternative autologous vein grafts. METHODS We analyzed all consecutive patients treated at an academic tertiary referral center between January 1998 and July 2018 using either the AV or SSV as the main peripheral bypass graft. Study end points were primary patency, secondary patency, limb salvage, and survival. RESULTS In total, 416 bypass procedures using exclusively AV (n = 327) or SSV (n = 89) were performed. There was a predominance of male gender. The majority of risk factors were evenly distributed between groups. The mean follow-up period was 2.3 years (0.9 to 13.3 years). Five-year primary and secondary patency rates were 39% (95% CI: 31-47%) and 67% (59-75%) for AV and 53% (41-66%) and 76% (67-86%) for SSV, respectively (P = 0.2 and 0.25). The five-year limb salvage and survival rates were 71% (68-81%) and 84% (77-90%) for AV and 78% (67-88%) and 90% (82-98%) for SSV, respectively (P = 0.52 and 0.11). CONCLUSIONS Both AV and SSV are equally effective alternatives for peripheral bypass if no GSV is available. Although there was a trend toward better results with the SSV, there was no significant difference between the 2 options.

Abstract
BACKGROUND Bypass in the upper extremity is a rare procedure mainly performed for chronic ischemia, trauma, or hemodialysis access complications. Feasibility and success of use of the arm vein and small saphenous vein (SSV) for autologous vein bypass have been reported in peripheral artery bypass procedures. There are very few reports on the use of alternative veins in upper extremity bypass. We report our experience with arm vein and SSV as a graft source in upper extremity arterial disease. METHODS Retrospective analysis of a consecutively collected case series in an academic tertiary referral center from January 2010 to February 2018. Study end points were primary patency, secondary patency, limb salvage, and survival. RESULTS In total, 47 patients were treated with upper extremity bypass either using the SSV (n = 17) or arm veins (n = 30). Indications were either acute (n = 12) or chronic ischemia (n = 35) caused by acute (n = 8) and chronic (n = 9) trauma, sequela of iatrogenic interventions (n = 4), peripheral artery disease (n = 14), thrombangiitis obliterans (n = 3), and dialysis-access-related complications (n = 9). An arm vein was used in 30 and the SSV in 17 patients. Primary patency after 12 months was 87% with the SSV and 75% with an arm vein (P = 0.8) and 63% and 75% after 36 months (P = 0.9). Secondary patency were 100% with an arm vein and 100% with the SSV after 36 months (P = 0.4). One patient had to undergo major amputation and 2 minor amputations. CONCLUSIONS Arm vein revascularization using the primarily arm vein or SSV as a bypass conduit can be performed with reasonable mortality and morbidity rates and provide good results comparable with the greater saphenous vein.

Abstract
Purpose Use of a composite graft combining a polytetrafluoroethylene graft with an autogenous vein is an option for limb salvage in the absence of an adequate single segment vein graft. We aimed to investigate the results of infrainguinal bypass with a composite graft. Materials and Methods We retrospectively reviewed 11 infrainguinal arterial bypasses on 11 limbs which underwent surgery from March 2012 to November 2016. Results Critical limb ischemia was common (63.6%) indication of bypass surgery and most (90.9%) of the patients had history of failed previous treatment including endovascular treatment (36.4%) and bypass surgery (72.7%). At the 2 years after graft implantations, primary patency and amputation-free survival of below-knee bypasses using composite graft were 73% and 76%, respectively. Conclusion Infrainguinal arterial bypasses with composite graft had an acceptable patency. In patients without other alternative conduits for revascularization, bypass with a composite graft can be an option.

Abstract
Purpose: The superiority of autogenous vein conduits is well known in lower extremity arterial bypass (LEAB). Among various alternative conduits for LEAB, long-term results of arm vein grafts were investigated in this study. Materials and Methods: We retrospectively reviewed clinical characteristics of 28 patients who underwent infrainguinal LEAB with autogenous arm vein grafts at a single institute between January 2003 and December 2015. All procedures were performed in the absence of adequate saphenous veins. Graft patency was determined by periodic examinations with duplex ultrasonography. Results: Autologous arm vein grafts were implanted for 28 patients (mean age, 60.4±16.8 years; range, 20–82 years; male, 92.9%; atherosclerosis, 19 [67.9%]; and non-atherosclerotic disease 9 [32.1%] including 5 patients with Buerger’s disease). Source of arm vein were basilic 13 (46.4%), cephalic 4 (14.3%) and composition graft with other veins in 11 (39.3%) cases. The level of distal anastomosis was distributed as popliteal in 5 (17.9%), tibio-peroneal in 21 (75.0%) and inframalleolar artery in 2 (7.1%) cases. Mean duration of follow-up was 41.5±46.9 months (range, 1–138 months). Cumulative primary patency rates at 1, 3, and 5 years were 66.5%, 60.9% and 60.9%, respectively. Assisted-primary patency rates at 1, 3 and 5 years were 66.5%, 66.5% and 66.5%, respectively. Secondary patency rates at 1, 3 and 5 years were 70.8%, 70.8% and 70.8%, respectively. There was one limb amputation during the follow-up period. Conclusion: Arm veins are a useful alternative conduit when great saphenous veins are not available during LEAB.

Abstract
The mainstay of treatment for long-segment small-vessel chronic occlusive disease not amenable to endovascular intervention remains surgical bypass grafting using autologous vein. The procedure is largely successful and the immediate operative results almost always favorable. However, the lifespan of a given vein graft is highly variable, and less than 50% will remain primarily patent after 5 years. The slow process of graft malfunction is a result of the vein's chronic maladaptive response to the systemic arterial environment, its primary component being the uncontrolled proliferation of vascular smooth muscle cells (SMCs). It has recently been suggested that this response might be attenuated through pre-implantation genetic modification of the vein, so-called gene therapy for the extension of vein graft patency. Gene therapy seems particularly well suited for the prevention or postponement of vein graft failure since: (1) the stimulation of SMC proliferation appears to largely be an early and transient process, matching the kinetics of current gene transfer technology; (2) most veins are relatively normal and free of disease at the time of bypass allowing for effective gene transfer using a variety of systems; and (3) the target tissue is directly accessible during operation because manipulation and irrigation of the vein is part of the normal workflow of the surgical procedure. This review briefly summarizes the current knowledge of the incidence and basic mechanisms of vein graft failure, the vector systems and molecular targets that have been proposed as possible pre-treatments, the results of experimental genetic modification of vein grafts, and the few available clinical studies of gene therapy for vascular proliferative disorders.

Abstract
BACKGROUND There is a need to better define the role of alternative autologous vein (AAV) segments over contemporary prosthetic conduits in patients with critical limb ischemia when great saphenous vein (GSV) is not available for use as the bypass conduit. METHODS Consecutive patients who underwent bypass to infrageniculate targets between 2007 and 2011 were categorized in three groups: GSV, AAV, and prosthetic. The primary outcome was graft patency. The secondary outcome was limb salvage. Cox proportional hazards regression was used to adjust for baseline confounding variables. RESULTS A total of 407 infrainguinal bypasses to below-knee targets were analyzed; 255 patients (63%) received a single-segment GSV, 106 patients (26%) received an AAV, and 46 patients (11%) received a prosthetic conduit. Baseline characteristics were similar among groups, with the exception of popliteal targets and anticoagulation use being more frequent in the prosthetic group. Primary patency at 2 and 5 years was estimated at 47% and 32%, respectively, for the GSV group; 24% and 23% for the AAV group; and 43% and 38% for the prosthetic group. Primary assisted patency at 2 and 5 years was estimated at 71% and 55%, respectively, for the GSV group; 53% and 51% for the AAV group; and 45% and 40% for the prosthetic group. Secondary patency at 2 and 5 years was estimated at 75% and 60%, respectively, for the GSV group; 57% and 55% for the AAV group; and 46% and 41% for the prosthetic group. In Cox analysis, primary patency (hazard ratio [HR], 0.55; P < .001; 95% confidence interval [CI], 0.404-0.758), primary assisted patency (HR, 0.57; P = .004; 95% CI, 0.388-0.831), and secondary patency (HR, 0.56; P = .005; 95% CI, 0.372-0.840) were predicted by GSV compared with AAV, but there was no difference between AAV and prosthetic grafts except for the primary patency, for which prosthetic was protective (HR, 0.38; P < .001; 95% CI, 0.224-0.629). Limb salvage was similar among groups. CONCLUSIONS AAV conduits may not offer a significant patency advantage in midterm follow-up over prosthetic bypasses.

Abstract
BACKGROUND Many patients with peripheral vascular disease (PAD) requiring revascularization do not have adequate ipsilateral great saphenous vein (GSV) for constructing a bypass because of intrinsic vein disease or prior harvesting for limb or coronary bypass. Prosthetic conduits have poor long-term patency, especially for distal bypass. With advancing endovascular sophistication, tibial angioplasty may be a good revascularization option, but we hypothesize that using spliced arm vein for distal lower extremity bypass is still a well-tolerated and more durable solution. METHODS A retrospective chart review was conducted of all PAD patients undergoing lower extremity bypass or tibial angioplasty for lifestyle-limiting claudication or critical limb ischemia at a single institution over a 7-year period. Statistical analysis was conducted by Kaplan-Meier survival analysis and Cox proportional hazards model. Statistical significance was set at P = 0.05. RESULTS From 2005 to 2012, there were 120 patients who underwent infrageniculate revascularization with conduit other than GSV. Over half of the patients (66 patients, 71.2% male, mean age 62 years) underwent bypass operations using arm vein conduit, and 88% of those bypasses were to tibial vessels. Patency was 100% at 1 year and 85% at 2 years. There was no impact on patency or amputation rate based on the source of vein or the number of splices. Forty-three patients underwent tibial angioplasty and patency was 70% at 1 year and 50% at 2 years. CONCLUSIONS When GSV is not available, spliced arm vein grafts provide durable lower extremity revascularization with favorable patency and limb preservation rates. Spliced arm vein grafts should be considered over prosthetic grafts and angioplasty alone in patients with distal occlusive disease.

Abstract
BACKGROUND The aim of this randomized study was to determine whether arm vein (AV) or contralateral greater saphenous vein (CGSV) is the better alternative vein source for lower extremity bypass reconstruction. METHODS Consecutive patients with absent ipsilateral greater saphenous vein undergoing lower extremity revascularization were allocated to group A (AV bypass) or B (CGSV bypass). RESULTS From 6, 2010, to 11, 2013, 64 patients (32 each group) were randomized. In all, 29 of 93 patients had to be excluded for various reasons. Median age was 76 years vs. 71 years (P = 0.01) for group A and B patients. There were no statistically significant differences regarding gender, cardiovascular risk factors, redo bypass procedures (P = 0.77), below-knee bypass procedures (P = 0.61), median bypass length (P = 0.6), and median length of incision on ipsilateral leg to perform anastomoses (P = 0.2) between group A and B patients, respectively. Incisions for vein harvest were longer in group A (P = 0.003). Overall surgical site infections (SSIs, P = 1.0) and SSI from vein harvest (P = 1.0) were equally distributed. No patient was lost to follow-up (17 vs. 18 months, P = 0.74). There was no statistically significant difference regarding primary (P = 0.77) and secondary (P = 0.25) patency rates at 1 year (group A: 52% vs. group B: 54% and group A: 72% vs. group B: 61%) and at 2 years (52% vs. 48% and 64% vs. 61%), respectively. There were 4 vs. 6 major amputations (P = 0.23) and 5 vs. 2 deaths (P = 0.1) in groups A and B during follow-up. CONCLUSIONS Preliminary results suggest that both AV and CGSV may serve as a secondary vein bypass graft equally well.

Abstract
OBJECTIVE Despite poor long-term patency, acceptable limb salvage has been reported with cryopreserved saphenous vein bypass (CVB) for various indications. However, utility of CVB in patients with critical limb ischemia (CLI) remains undefined. The purpose of this analysis was to determine the role of CVB in CLI patients and to identify predictors of successful outcomes. METHODS A retrospective review of all lower extremity bypass (LEB) procedures at a single institution was completed, and CVB in CLI patients were further analyzed. The primary end point was amputation-free survival. Secondary end points included primary patency and limb salvage. Life tables were used to estimate occurrence of end points. Cox regression analysis was used to determine predictors of limb salvage. RESULTS From 2000 to 2012, 1059 patients underwent LEB for various indications, of whom 81 received CVB for either ischemic rest pain or tissue loss. Mean age (± standard deviation) was 66 ± 10 years (male, 51%; diabetes, 51%; hemodialysis dependence, 12%), and 73% (n = 59) had history of failed ipsilateral LEB or endovascular intervention. None had sufficient autogenous conduit for even composite vein bypass. Infrainguinal CVB (infrapopliteal target, 96%; n = 78) was completed for multiple indications including Rutherford class 4 (42%; n = 34), class 5 (40%; n = 32), and class 6 (18%; n = 15). Eleven (14%) had CLI and concomitant graft infection (n = 8) or acute on chronic ischemia (n = 3). Intraoperative adjuncts (eg, profundaplasty, suprainguinal stent or bypass) were completed in 49% (n = 40) of cases. Complications occurred in 36% (n = 29), with 30-day mortality of 4% (n = 3). Median follow-up for CLI patients was 11.8 (interquartile range, 0.4-28.4) months with corresponding 1- and 3-year actuarial estimated survival (± standard error mean) of 84% ± 4% and 62% ± 6%. Primary patency of CVB for CLI was 27% ± 6% and 17% ± 6% at 1 and 3 years, respectively. Amputation-free survival was 43% ± 6% and 23% ± 6% at 1 and 3 years, respectively, and significantly higher for rest pain (59% ± 9%, 36% ± 10%) compared with tissue loss (31% ± 7%, 14% ± 7%; log-rank, P = .04). Freedom from major amputation after CVB for CLI was 57% ± 6% and 43% ± 7% at 1 and 3 years. Multivariable predictors of limb salvage for the CVB CLI cohort included postoperative warfarin (hazard ratio [HR], 0.4; 95% confidence interval [CI], 0.2-0.8), dyslipidemia (HR, 0.4; 95% CI, 0.2-0.9), and rest pain (HR, 0.4; 95% CI, 0.2-0.9). Predictors of major amputation included graft infection (HR, 3.1; 95% CI, 1.1-9.0). CONCLUSIONS In CLI patients with no autologous conduit and prior failed infrainguinal bypass, CVB outcomes are disappointing. CVB performs best in patients with rest pain, particularly those who can be anticoagulated with warfarin. However, it may be an acceptable option in patients with minor tissue loss or concurrent graft infection, but consideration should be weighed against the known natural history of nonrevascularized CLI and nonbiologic conduit alternatives, given potential cost implications.

Abstract
Successful treatment of patients with critical limb ischemia (CLI), hinges on the adequacy of revascularization. However, CLI is associated with a severe burden of systemic atherosclerosis, and patients often suffer from multiple cardiovascular comorbidities. Therefore, CLI patients in general represent a cohort at increased risk for procedural complications and adverse events. Although endovascular therapy represents a minimally invasive alternative to open surgical bypass, the durability of surgical reconstruction is superior, and it remains the "gold standard" approach to revascularization in CLI. Therefore, selection of the optimal treatment modality for individual patients requires careful consideration of the procedural risks and likelihood of adverse events associated with surgery. Individualized decision-making with regard to revascularization strategy requires a comprehensive understanding of the likelihood of adverse outcomes after major surgery. Here we review the risks of surgical bypass in patients with CLI, with particular emphasis on the identification of preoperative variables that predict poor outcome.

Abstract
BACKGROUND The superiority of autogenous conduits in infrainguinal bypass surgery is well established. At our institution, arm vein is utilized as the last autogenous option for infrainguinal bypass surgery. The aim of this study was to review the long-term outcomes of last autogenous option arm vein bypass. METHODS All infrainguinal arm vein bypasses performed between 1997 and 2005 by The Queen Elizabeth Hospital vascular surgeons were identified. Patency, reintervention, limb salvage and survival were calculated using the Kaplan-Meier survival estimate method. RESULTS Thirty-eight arm vein bypasses were performed in 35 patients. Eighty-nine per cent were performed for critical limb ischaemia. Median follow-up was 58 months (range 2-121). Twelve-month primary, assisted primary and secondary patency rates were 52%, 73% and 76%, respectively. Three-year primary, assisted primary and secondary patency rates were 32%, 61% and 63%, respectively. Five-year primary, assisted primary and secondary patency rates were 21%, 47% and 49%, respectively. Patency was superior in single compared with spliced vein grafts (P < 0.05). Limb salvage rates at 1, 3 and 5 years were 94%, 87% and 76%, respectively. Patient survival at 1, 3 and 5 years was 92%, 68% and 49%, respectively. DISCUSSION Infrainguinal bypass surgery with arm vein can be performed safely with favourable patency and high rates of limb salvage. Secondary interventions to maintain patency are common and we recommend a vigilant surveillance programme to identify the threatened graft.

Abstract
The etiology of foot lesions in diabetics is multifactorial. Arterial insufficiency, neuropathy, and susceptibility to infection are major factors contributing to the formation of nonhealing diabetic foot lesions. These factors lead to a 15% ulceration rate in diabetics with 20% resulting in amputation. This amputation rate, 4.1 per 1,000 per year, represents a risk 40 times greater for diabetics, with a subsequent second amputation in 60% by 5 years. Conversely, more than half of all lower-extremity amputations are performed in diabetic patients. Therefore, the primary goal in diabetic lower-extremity care is to heal foot ulcerations and prevent amputations and major disabilities. Lower-extremity revascularization is a major facet of achieving the goal of healing and amputation prevention. Due to the severity, distribution, and complexity of diabetic vascular disease, surgical bypass continues to play a role in attaining this goal. Surgical bypass might be the best option for diabetic patients with significant tissue loss or to revascularize the appropriate angiosome of the foot and maximize healing potential. In order to offer surgical bypass to these patients, innovative techniques might need to be considered, including venous patches and cuffs, heparin-bonded grafts, and adjunctive distal arteriovenous fistulas.

Abstract
The overall therapeutic strategy in patients with diabetes mellitus and peripheral arterial disease affecting several arterial segments is problematic. Usually, the greater saphenous vein (GSV) is the gold standard for bypass. However, alternative venous grafts may be necessary when the GSV is not available. The superficial veins of the arm are not suitable for bypass operations in most cases because of anatomical variations, inadequate diameter or very thin walls. However, arterialization of the cephalic vein can dilate and strengthen the walls, thus avoiding postoperative complications. The present patient, whose case was followed for 20 months postoperatively, suffered both from diabetes and peripheral arterial disease in a setting of gangrene and a lack of the GSV. The treament of the patient and the problems it incurred are discussed. The advantages of preoperative temporary arteriovenous shunting to improve the quality of the cephalic vein as an alternative autogenous graft are analyzed. Currently, the patient has excellent postoperative results, with healing of the ulcers and preserved peripheral pulses.

Abstract
BACKGROUND One-piece great saphenous vein (GSV) is the conduit of choice in infrainguinal revascularizations for critical limb ischemia (CLI). Unfortunately, adequate length of usable GSV is not always available. Despite inferior patency rates compared with GSV, prosthetic and arm vein conduits are generally considered usable. The purpose of this study was to compare the outcome of infrainguinal arm vein and prosthetic bypass. MATERIAL AND METHODS We retrospectively reviewed 290 consecutive infrainguinal bypasses for CLI using arm vein conduit (n = 130) or prosthetic graft (n = 160) during January 2000 and December 2006 at our institution. The groups were compared for risk factors, indication for surgery, and runoff score. Survival, leg salvage, and patency rates were calculated with the Kaplan-Meier method. RESULTS Median surveillance time was 35 months (range 0-118 months). The age, gender, and usual risk factors were similar in arm vein and prosthetic groups, except cerebrovascular disease that was more common in the prosthetic group (P = .011). Indication for surgery was CLI. In the arm vein group, more than two-thirds (70.2%) of the procedures were for ischemic ulcer or gangrene, whereas in the prosthetic group the main indication was ischemic rest pain (51.3%). When the outcome of femoropopliteal bypasses was analyzed, the difference between groups was not statistically significant. However, in infrapopliteal revascularizations primary patency, assisted primary patency, and secondary patency rates at 3 years were significantly better in the arm vein group: 28.3% (SE +/- 6.3%) vs 9.6% (SE +/- 8.1%) (P = .031), 56.8% (SE +/- 6.6%) vs 10.4% (SE +/- 8.7%) (P = .000), and 57.4% (SE +/- 6.6) vs 11.2% (SE +/- 9.3%) (P = .000), respectively. Leg salvage and survival at 3 years were 75.0% (SE +/- 4.9%) vs 57.1% (SE +/- 8.8%) (P = .005) and 58.8% (SE +/- 5.1%) vs 39.5% (SE +/- 7.7%) (P = .007), respectively. CONCLUSION Arm vein conduits, even when spliced, are superior to prosthetic grafts in terms of midterm assisted primary patency, secondary patency, and leg salvage in infrapopliteal bypasses for CLI.

Abstract
Critical limb ischemia (CLI) remains a poorly understood, rarely reported, and inconsistently treated major global healthcare epidemic. The incidence in the US is estimated at 1% of the population aged 50 years and older and at approximately double that rate in the over-70 age group. These frequencies are expected to increase significantly with the aging population and the expected increase in diabetes. Within 1 year of being diagnosed with CLI, 40% to 50% of the now 20 million US diabetics will experience an amputation, and 20% to 25% will die. The estimate for treating CLI in the US alone is $10 to $20 billion per year, but just a 25% reduction in amputations could save $2.9 to $3.0 billion annually. Infrainguinal bypass surgery (IBS) utilizing autogenous saphenous vein has been considered the "24-carat gold standard" treatment for CLI, but over the last decade, endovascular therapy has emerged to seriously challenge IBS, which has created considerable controversy. Despite an overall lack of "hard" level I data, many interventionists are questioning the role of IBS as a first-line CLI therapy or are at least now considering IBS a "tainted" gold standard ("14-carat"). This review will examine the available evidence, but there should be no doubt regarding the huge global clinical and economic impact of CLI and amputations.

Abstract
OBJECTIVES Considerable evidence exists for the use of arm vein conduit in lower limb bypass surgery. The use of arm vein in preference to synthetic conduit as a last autogenous option was assessed for patency and limb salvage outcomes. MATERIALS AND METHODS A prospective database was interrogated and checked against TQEH operating theatre database to detect all infrainguinal arm vein bypasses performed between 1997 and 2005. Patency, limb salvage and survival data for 37 arm vein bypasses was calculated using the Kaplan-Meier survival estimate method. RESULTS There were no perioperative deaths. 30 day patency rates were 89% primary, 95% secondary and 95% limb salvage. 12 month patency rates were 56% primary, 79% secondary and 91% limb salvage. 5 year patency rates were 37% primary, 76% secondary and 91% limb salvage. There was no significant patency advantage for primary vs. "redo" grafts (p=0.54), single vessel vs. spliced conduits (p=0.33) or popliteal vs tibial outflow (p=0.80). Patient survival rate was 92% and 65% at 1 and 5 years respectively. CONCLUSION Lower limb bypasses using arm vein can be performed with favourable patency and limb salvage compared to synthetic conduits. However, secondary interventions are frequently required to maintain patency. We recommend a vigilant surveillance program for early identification of patency threatening disease.

Abstract
OBJECTIVE The aim of this study was to assess the outcome of infrapopliteal bypass when an adjuvant arteriovenous (AV) fistula was reconstructed as means of rescue as a result of poor runoff. The design was a retrospective multicenter case-control study. METHODS Seventy-seven infrapopliteal vein bypasses required an adjuvant AV fistula among 1813 patients operated on for critical leg ischemia in 3 vascular centers between 1996 and 2003. The mean age was 74 years (range, 39-90 years). A total of 70% of the patients had diabetes, and 24% had undergone previous vascular surgery. In 25% of the bypasses, the distal anastomosis was in a crural artery, in 55% it was in the dorsal pedal artery, and in 20% it was in a plantar artery. An adjuvant AV fistula was reconstructed in all cases because of poor intraoperative arterial status, intraoperative angiography, or low intraoperative flow. A control group was retrieved that matched the study group according to the recipient artery and runoff score. RESULTS The primary and secondary patency were 61% and 75%, respectively, at 1 year in the AV fistula group and 57% and 71% in the control group. The 3-year patency rates were 49% and 62% for the AV fistula group and 46% and 71% for the control group, respectively. There was a 76% leg-salvage rate at 3 years in the study group, compared with 87% in the control group. There were no major complications related to the AV fistula. Intraoperative flow was increased from a median of 20 mL/min to 115 mL/min by the AV fistula (P = .003). The graft flow was significantly higher in the AV fistula group than in the control group (P = .001). CONCLUSIONS The adjuvant AV fistula increased graft flow significantly in a poor-outflow venous bypass. In this extreme patient group, acceptable patency and leg salvage was achieved without adverse effects. Despite this, the AV fistula did not improve the outcome.

Abstract
Background—
The purpose of this study was to assess the benefits of duplex compared with clinical vein graft surveillance in terms of amputation rates, quality of life, and healthcare costs in patients after femoropopliteal and femorocrural vein bypass grafts.
Methods and Results—
This was a multicenter, prospective, randomized, controlled trial. A total of 594 patients with a patent vein graft at 30 days after surgery were randomized to either a clinical or duplex follow-up program at 6 weeks, then 3, 6, 9, 12, and 18 months postoperatively. The clinical and duplex surveillance groups had similar amputation rates (7% for each group) and vascular mortality rates (3% versus 4%) over 18 months. More patients in the clinical group had vein graft stenosis at 18 months (19% versus 12%,
P
=0.04), but primary patency, primary assisted patency, and secondary patency rates, respectively, were similar in the clinical group (69%, 76%, and 80%) and the duplex group (67%, 76%, and 79%). There were no apparent differences in health-related quality of life, but the average health service costs incurred by the duplex surveillance program were greater by £495 (95% CI £183 to £807) per patient.
Conclusions—
Intensive surveillance with duplex scanning did not show any additional benefit in terms of limb salvage rates for patients undergoing vein bypass graft operations, but it did incur additional costs.

Abstract
The objectives of this study were to evaluate the results of polytetrafluoroethylene infragenicular bypass grafts with a distal interposition vein cuff in patients with critical limb ischemia in the absence of ipsilateral greater saphenous vein. From January 1997 to June 2002, 58 consecutive below-knee bypass grafts with PTFE and distal interposition vein cuff were performed in 57 patients with a median age of 70.8 years. The distal anastomosis was located at the infragenicular popliteal artery in 18 cases and at tibial vessels in 40. Primary patency, secondary patency, and limb salvage were analyzed using the Kaplan-Meier method. During a median follow-up of 14.4 months (range, 1-50) 26 cases of graft occlusion and 19 major amputations were registered. The primary and secondary patency rates at 12, 24, and 36 months were 57%, 54%, and 47% and 61%, 58%, and 50%, respectively. Limb salvage rates reached 69%, 69%, and 59% at 12, 24, and 36 months. When below-knee revasculanzation is required in patients with limb-threatening ischemia, in the absence ipsilateral greater saphenous vein, PTFE grafts with a distal vein cuff are a reasonable substitute with acceptable long-term patency and limb salvage rates.

Abstract
OBJECTIVE Infrainguinal bypass grafting with arm vein is associated with lower patency rates compared with saphenous vein conduits. In this study the effect of a duplex ultrasound surveillance program to enable identification and treat graft lesions with open or endovascular repair on patency was analyzed. METHODS Over 9 years 89 infrainguinal arm vein (26% spliced vein) bypasses were performed to treat critical lower limb ischemia in 89 patients without adequate saphenous vein conduits. Seventy-six (85%) of the bypasses were repeat procedures. Grafts were assessed at operation with duplex ultrasound scanning, then enrolled in a surveillance program. Graft stenoses with peak systolic velocity greater than 300 cm/s and velocity ratio greater than 3.5, detected at duplex ultrasound scanning, were repaired with percutaneous transluminal balloon angioplasty (PTA) if specific criteria were met, including greater than 3 months since primary procedure, lesion length less than 2 cm, and graft diameter greater than 3.5 mm, or with open surgical repair for early appearing or extensive graft lesions. RESULTS During a mean 26-month follow-up, duplex surveillance resulted in a 48% (43 bypasses) intervention rate. Primary patency rate was 43% at 3 years. Twenty-six (43%) of 61 lesions identified and repaired met criteria for PTA; the remaining 35 graft lesions (stenosis, n = 30; vein graft aneurysm, n = 5) were surgically corrected with vein patch angioplasty (n = 15), interposition grafting (n = 13), jump graft bypass (n = 6), or open repair (n = 1). At 3 years the assisted primary patency rate was 91% (7 graft failures). Multiple interventions were performed in 18 (42%) revised grafts because of metachronous (n = 6) or repair site stenosis (n = 12). In 18 graft interventions (PTA, n = 9; surgery, n = 9) recurrent stenosis developed, and endovascular therapy was used in one third (n = 6). At 3 years the stenosis-free patency rate for PTA (48%) and surgically repaired (53%) graft lesions was similar. CONCLUSIONS Arm veins used in lower limb bypass procedures are prone to development of stenosis and aneurysm, lesions easily detected with a life-long duplex ultrasound surveillance program. Excellent long-term patency (91%) was achieved despite graft intervention being performed in nearly half of all bypasses and one third of revised grafts. Endovascular treatment was possible in half of all graft stenosis, with outcomes similar to those with surgical repair.

Abstract
Subintimal recanalization is a percutaneous technique that allows revascularization in patients with limb-threatening ischemia. It was first described by Bolia (Cardiovasc Intervent Radiol 13;357–63:1990) but has not gained widespread use in the United States. Twenty-five patients with 32 threatened limbs were referred from a single surgeon's practice over a 23-month period. All patients were either high-risk surgical patients, due to severe medical comorbidities, or not surgical candidates due to poor target vessels, lack of appropriate conduit, or failed previous surgical revascularizations. The average age of patients was 69. There were 15 men and 10 women treated. Subintimal recanalization was immediately successful in 30 limbs. One peri-procedural death occurred, although this patient underwent a surgical bypass graft procedure in the same hospitalization. Three significant complications occurred (myocardial infarction, ventricular arrhythmia, and gastrointestinal hemorrhage). Primary patency is 83 per cent. Secondary patency is 90 per cent. Limb salvage rate is 88 per cent. Mean follow-up period is 10 months. Eight patients died in the follow-up period due to unrelated causes.

Abstract
OBJECTIVE The purpose of this study was to examine the outcome of patients in whom an infrainguinal bypass graft failed. METHODS This was a retrospective analysis of consecutive patients undergoing infrainguinal bypass grafting in a single institution over 8 years. RESULTS Six hundred thirty-one infrainguinal bypass grafts were placed in 578 limbs in 503 patients during the study period. The indication for surgery was limb-threatening ischemia in 533 patients (85%); nonautologous conduits were used in 259 patients (41%), and 144 (23%) were repeat operations. After a mean follow-up of 28 +/- 1 months (median, 23 months; range, 0-99 months), 167 grafts (26%) had failed secondarily. The rate of limb salvage in patients with graft failure was poor, only 50% +/- 5% at 2 years after failure. The 2-year limb salvage rate depended on the initial indication for bypass grafting: 100% in patients with claudication (n = 16), 55% +/- 8% in patients with rest pain (n = 49), and 34% +/- 6% in patients with tissue loss (n = 73; P <.001). The prospect for limb salvage also depended on the duration that the graft remained patent. Early graft failure (<30 days; n = 25) carried a poor prognosis, with 2-year limb salvage of only 25% +/- 10%; limb salvage was 53% +/- 5% after intermediate graft failure (<2 years, n = 110) and 79% +/- 10% after late failure (>2 years, n = 15; P =.04). Multivariate analysis revealed shorter patency interval before failure (P =.006), use of warfarin sodium (Coumadin) postoperatively (P =.006), and infrapopliteal distal anastomosis (P =.01) as significant predictors for ultimate limb loss. CONCLUSION The overall prognosis for limb salvage in patients with failed infrainguinal bypass grafts is poor, particularly in patients with grafts placed because of tissue loss and those with early graft failure.

Abstract
For a femorotibial bypass graft the material of choice is autologous vein. The question remains whether prosthetic material is a reasonable alternative for limb salvage, if autologous vein is not available. From 1991 to 1998, 83 consecutive femorotibial bypass procedures were performed in 70 patients. Thin-walled, ringed 6-mm polytetrafluoroethylene (PTFE) was used, as autologous vein was not available. The indication for the femorotibial bypass was critical ischemia due to atherosclerotic occlusive disease in all cases. Three patients died in the hospital or within 30 days of the operation, resulting in a perioperative mortality rate of 3.6%. After 5 years, 33 patients had died (40%) and 3 patients were lost to follow-up (3.6%). Primary patency was 64.2% after 6 weeks and 18% +/- 5% after 5 years. Secondary patency was 74.1% after 6 weeks and 22.3% +/- 6% after 5 years. When we compared primary and secondary patency for distal anastomosis, there was no difference between the three crural arteries. The limb salvage rate was 61.9% +/- 7% after 5 years. From these results we conclude that, with a limb salvage of 61.9%, PTFE is an acceptable alternative for a femorotibial bypass graft in patients with critical ischemia, if autologous vein is not available.

Abstract
INTRODUCTION homografts have been used since the early days of vascular surgery, but have failed to provide long-term success. Arteries supplying organ transplants seldom show signs of biodegradation. We therefore introduced fresh arterial homograft repair with consecutive immunosuppression (ATX). AIM to assess feasibility and clinical usefulness of ATX. SETTING university teaching hospital. MATERIAL AND METHOD conduits were harvested during multi-organ procurement and stored in Custodiol. Implantation followed immediately. Viability of the transplant was documented in all cases. Patients received immunosuppression for the duration of bypass function. RESULTS thirteen patients received ATX for critical limb ischaemia (M/F: 11/2, age: 62yr, previous revascularisations: 4.5 (1-8), median run-off index 5, previous organ transplant: n=2. Most bypasses were anastomosed to single tibial or pedal vessels. There was no early failure. Within an average follow up of 12 months there were 6 graft thromboses in 5 patients, successfully revised in 4. Three limbs were lost after 2, 5 and 6 months due to graft failure. Graft rejection was shown in 1 out of 3 explanted grafts. CONCLUSION we report a concept, which may circumvent the problem of biologic graft degeneration. Limb salvage was possible in 75% at 12 months in otherwise difficult circumstances.

Abstract
Infrageniculate (below-knee) bypass using all-autogenous composite vein requires multiple incisions, venovenostomy, and prolonged operating time. The purpose of this study was to evaluate the long-term results of this procedure, with comparisons to grafts created from single-segment greater saphenous vein (GSV) or polytetrafluoroethylene (PTFE). A total of 362 consecutive infrainguinal bypass grafts with infrageniculate distal target arteries were created in 283 patients in a single institution between January 1995 and December 2000. Comorbid conditions were common, including diabetes (58%), coronary artery disease (56%), prior lower extremity revascularization (41%), end-stage renal failure (20%), and prior coronary artery bypass grafting (18%). The indication for revascularization was limb salvage in 93% of cases. The grafts were constructed from single segments of GSV (n = 239), from two or more vein segments resulting in an all-autogenous composite graft (n = 61), or from PTFE (n = 62). All-autogenous composite grafts were constructed using segments of ipsilateral or contralateral GSV (n = 49), upper extremity vein (n = 23), superficial femoral vein (n = 7), or lesser saphenous vein (n = 5). Infrageniculate all-autogenous composite vein grafts exhibited similar long-term results to those of GSV grafts, and far superior results to those of PTFE grafts. For patients with available autogenous segments, the all-autogenous composite vein graft is the conduit of choice.

Abstract
PURPOSE The purposes of this study were to evaluate the long-term results of different autogenous conduits used for infrainguinal bypass when ipsilateral greater saphenous vein (IGSV) is absent or inadequate and to determine the impact on the contralateral lower extremity. METHODS The study was performed as a retrospective evaluation of a prospective vascular registry together with review of patient records and telephone follow-up. RESULTS From January 1990 to June 2000, 226 autogenous infrainguinal reconstructions were performed in 203 patients without adequate IGSV. The patients consisted of 128 men and 98 women, with a mean age of 69 years. Prevalent risk factors included diabetes (51%) and prior coronary bypass (46%). Limb salvage was the predominant indication (93%), and 59% of the procedures were secondary reconstructions. All bypasses were completed with autogenous vein, which included contralateral greater saphenous vein (CGSV; 31%), single-segment lesser saphenous vein (5%), single-segment arm vein (19%), and autogenous composite vein (45%). Bypasses were performed to the tibial and pedal arteries in 84% of the cases. The 30-day mortality and graft occlusion rates were 1% and 9%, respectively. The overall postoperative morbidity rate was 24%, with a 7% rate of major complications. Follow-up was complete in 95% of patients over a mean period of 24 months (range, 0.1 to 106 months). The 5-year primary patency rates were significantly better for CGSV compared with autogenous composite vein grafts (61% +/- 7% versus 39% +/- 6%; P <.009). The 5-year secondary patency (60% to 73%) and limb salvage (78% to 81%) rates did not differ significantly between the three groups. Follow-up of the contralateral lower limb revealed that nine of 226 limbs (4%) were amputated at a mean of 36 months after the ipsilateral bypass. The overall 5-year contralateral limb preservation rate was 90% +/- 3%. Contralateral vein harvest and the presence of diabetes did not affect the need for bypass or amputation of the contralateral limb. CONCLUSION For most patients with inadequate IGSV, the CGSV is the alternative conduit of choice because of its length, superior performance, ease of harvest, and minimal risk to the donor limb.

Abstract
OBJECTIVE Single-piece vein remains the conduit of choice in patients who need bypass grafting for limb salvage. When this option is not available, two of the remaining options are prosthetic bypass graft or several segments of vein spliced together. In this study, we compare spliced vein bypass grafting versus polytetrafluoroethylene grafting with a distal vein cuff in patients with limb-threatening ischemia. METHODS Between 1996 and 2000, 39 bypass grafting procedures in 36 patients were performed for limb-threatening ischemia. These procedures were prospectively randomized to either spliced vein bypass grafting (spliced group, 19 bypass grafts) or polytetrafluoroethylene grafting with a distal vein cuff (cuff group, 20 bypass grafts). All the patients in the cuff group underwent anticoagulation therapy with warfarin sodium after surgery. The inclusion criteria included: no single-piece vein option for bypass grafting, adequate vein for splice, no composite sequential option, and limb-threatening ischemia. The demographics were similar between the two groups. RESULTS The primary patency rate at 2 years was 44% and 49% for the spliced and cuff groups, respectively. In the spliced group, seven of 19 bypass grafts underwent revision in the follow-up period, and two of 20 cuffed bypass grafts were successfully revised. The secondary patency rate was 87% and 59% (P <.05), with limb salvage rates of 94% and 85% for spliced and cuff groups, respectively. Four patients in the spliced vein group needed reoperation for wound complications related to vein harvest. One polytetrafluoroethylene graft needed removal for infection. Two early mortalities occurred in the spliced group, one from myocardial infarction and one from stroke. The overall survival rate at 2 years between the two groups was 67% and 100% for the spliced and cuff groups, respectively (P <.05). CONCLUSION Although this is a preliminary report, it appears that both spliced vein bypass grafting and polytetrafluoroethylene bypass grafting with a distal vein cuff produce acceptable limb salvage rates. The secondary patency rate for spliced vein is better, but these bypass grafts more often need revision or reoperation for wound complications.

Abstract
The authors reviewed the Vascular Surgery Registry at the Beth Israel Deaconess Medical Center between 1990 and 1996 and identified 45 patients (47 limbs) who underwent bypass with polytetrafluoroethylene alone to infra-popliteal vessels. This represented only 2.6% of total tibial bypasses performed during that time. Sixty-nine percent of patients had diabetes. Indication for bypass was limb salvage in 96% of patients. Primary and secondary patency rates at 30 days, 1, 3, and 5 years were 87%, 87%; 58%, 60%; 41%, 43%; and 36%, 39%; respectively. Limb salvage rates at 30 days, 1, 3, and 5 years were 91%, 68%, 63%, and 63%. Cumulative survival rates at 3 and 5 years, however, were 53%, and 42%. The 29 grafts (64%) that were postoperatively anticoagulated with sodium warfarin showed trends in improved primary patency (47% vs 19%, p = 0.07), secondary patency (49% vs 20%, p = 0.03), and limb salvage (67% vs 58%, p = 0.06), at 3 years. There were no significant differences between diabetics and non-diabetics except in a trend toward decreased patient survival at 3 and 5 years in the diabetic population. Postoperatively, there were no deaths but there were two (4.2%) major cardiac complications. These data support the judicious use of tibial vessel bypass using PTFE in selected patients for limb salvage when autologous vein is not available. Diabetic patients appear to have similar results to non-diabetics and the postoperative use of sodium warfarin is beneficial.

Abstract
Over an 8-year period, we performed 93 lower extremity bypasses using complex autologous conduits, which included (1) contralateral greater saphenous vein (GSV), (2) composite GSV, (3) superficial femoral vein, (4) lesser saphenous vein, (5) cephalic or basilic veins, and (6) composite-sequential (PTFE and vein) grafts. These grafts represented 16% of all infrainguinal bypasses during this period, and all grafts were performed to treat limb-threatening ischemia. Survival, patency, and limb salvage were examined by the life-table method. Primary graft patency was 46 and 38% at 3 and 5 years. Assisted-primary patency was 62 and 59%, and secondary graft patency rates were 68 and 64% at 3 and 5 years. Twenty-nine bypasses (31%) required revision to restore or maintain patency. The 3-year limb salvage rate was significantly better when revision was performed for graft stenosis than for graft thrombosis (90% vs. 46%, p < 0.05). Overall limb salvage rate was 73% at 5 years. The mortality rate was 5.4% and the 5-year survival was 51%. Complex autologous tibial bypasses provided acceptable long-term limb salvage in patients with severe ischemia and inadequate ipsilateral GSV. The increased operating time and complexity required did not produce prohibitive operative risks. Postoperative graft surveillance in these complex vein bypasses allowed revision in many cases before graft occlusion occurred and significantly improved long-term limb salvage.
