Different Characteristics

Background: This retrospective study evaluates the clinical outcomes of two heparin-bonded expanded polytetrafluoroethylene grafts, PROPATEN and ACUSEAL (W. L. Gore & Associates, Flagstaff, AZ, USA), for forearm loop vascular access. Methods: We prospectively collected data on 60 patients who had undergone arteriovenous graft of the forearm loop type between January 2015 and December 2019. The primary endpoints were graft primary, assisted primary, and secondary patency rates. Secondary endpoints were time to first cannulation and postoperative complications. Results: We enrolled 36 patients in the PROPATEN group (Group P) and 24 in the ACUSEAL group (Group A). All procedures were successful without any 30-day mortality. The median times to first cannulation were 16.5 days and 3 days in Groups P and A, respectively ( p < 0.001). Mean follow-up periods were 13.4 ± 14.5 and 17.3 ± 9.3 months, respectively. Primary patency rates were 81% and 64%, respectively, at 6 months, and 60% and 40%, respectively, at 12 months ( p = 0.008). Assisted primary patency rates were 96% and 83% at 6 months, 91% and 73% at 12 months, and 81% and 35% at 24 months ( p = 0.044). Secondary patency rates were 96% and 81% at 12 months, and 87% and 62% at 24 months ( p = 0.207). As a remote-period complication, disruption of the luminal layer of the graft was observed in two patients (4.2%) in Group A due to puncture and thrombectomy. Conclusions: Although the ACUSEAL graft offers the advantage of early cannulation, its primary and assisted primary patency outcomes were inferior to those of the PROPATEN graft. It is important for physicians to be aware of the different characteristics of each graft to select the best option for each patient.

Purpose: The purpose of this article is to study 1-year results of Zenith branch iliac endovascular graft (ZBIS) with the off-label use of a 13 mm spiral Z limb to connect to the aortic main body. Materials and Methods: A retrospective review from 2015 to 2019 of all iliac branch devices (IBDs) was performed at 1 institution that were connected to an aortic main body with a 13 mm spiral Z limb and had at least 1-year follow-up with computed tomography (CT). Primary endpoints are freedom from ZBIS separation from the connection limb, endoleak (EL), or reintervention at 1 year. Secondary endpoints are primary and secondary ZBIS patency, presence of any EL, and aortic reinterventions. Results: Of 149 IBDs implanted in this period, 45 ZBIS in 35 patients were connected with a 13 mm limb and had a 1-year CT; 97% of patients had common iliac artery (CIA) aneurysms, 7% of patients had hypogastric artery (HA) aneurysms, and 30% of patients had bilateral ZBIS implantation. Technical success was 98%. In 84% of cases, the Advanta V12 was used as the HA mating stent; 56% of patients had an EL, mostly type II, which resolved spontaneously in 70% at 1 year, and 9% of ZBIS required reinterventions at 1 year (2 for thrombosis, 2 for type Ic EL from HA mating stent). One-year ZBIS primary patency and secondary patency were 96% and 100%, respectively. No EL was noted to be related to the 13 mm connection limb. No migration or separation of the devices occurred. Conclusions: The use of 13 mm spiral Z limb to connect a ZBIS with the main body in our series yields a high technical success rate and good 12-month outcomes without device separation or migration.

Steal Syndrome

A Minimally Invasive Limited Ligation Endoluminal-assisted Revision (MILLER) banding procedure has been used for treating patients with dialysis access–related steal syndrome (DASS) and high-flow vascular access–related pulmonary hypertension (PHT) and heart failure (HF). We performed a retrospective analysis of patients undergoing the MILLER procedure performed for DASS, HF, and PHT from our Vascular Access Database from September 2017 to October 2019. Outcomes included primary patency of banding, primary assisted patency, and secondary patency, using time-to-event analyses with Kaplan-Meier curves and life tables to estimate 6- and 12-month rates. A total of 13 patients (6 men and 7 women, mean age 60 ± 14 years) underwent the MILLER procedure, 6 patients for DASS and 7 patients for pulmonary hypertension and heart failure (PHT/HF). Technical success was achieved in all patients. The longest duration of follow-up was 28 months (median 12 months [IQR 7, 19]). One patient died at 1 month after the intervention due to stroke. One patient developed access thrombosis of the graft 3 days after the procedure. Repeat banding was required in 1 patient 8 months after the first procedure. The 6-month primary patency rate of banding following this procedure was 83% while the 12-month rate was 66%. The 6- and 12-month secondary patency rates were 87% and 75%, respectively. The MILLER procedure can be performed for DASS and PHT/HF with improvement of symptoms and good long-term patency rates. Additional interventions to maintain patency and efficacy are required on long-term follow-up.

Background: Creating and maintaining a functioning arteriovenous access is essential for long-term hemodialysis patients. Transposed brachiobasilic fistula (BBF) or arteriovenous graft (AVG) becomes an option when radiocephalic or brachiocephalic fistula cannot be created or fails. This study compared the patency and complications between BBFs and AVGs among patients on hemodialysis. Methods: A retrospective study was performed in Shuang Ho Hospital, Taiwan, from November 2015 to May 2020. All the operations were done by a single surgeon. Primary outcomes were primary patency, primary-assisted patency, and secondary patency of the BBF and AVG groups. Secondary outcomes were incidence of complications and reinterventions. Results: Of the 144 consecutive patients, 20 and 124 patients underwent BBF and AVG creation, respectively. Median follow-up time was 19.2 months. Primary patency at 1 and 2 years were 67% and 19% in the BBF group and 44% and 16% in the AVG group (P = 0.126). Primary-assisted patency at 1 and 2 years were 82% and 54% in the BBF group and 54% and 30% in the AVG group (P = 0.012). Secondary patency at 1 and 2 years were 100% and 82% in the BBF group and 81% and 67% in the AVG group (P = 0.078). The incidence of complication was significantly higher in the AVG than in the BBF group (1.7 per patient-year vs 0.93, P < 0.001). Conclusion: Compared with the AVG group, BBF group showed better primary-assisted patency, less complication and intervention rates. Therefore, BBF is a reliable option for patients with exhausted cephalic veins if basilic vein is available for reconstruction.

Abstract Background and Aims With the increase in the line expectancy of chronic kidney disease in the older population (&gt;60 years), the numbers requiring haemodialysis is progressively rising. The elderly population may be different from the younger in terms of non-suitable vessels for access creation, non-maturation, and vascular calcifications, and this may alter the outcomes of use of arteriovenous fistula (AVF). This study was conducted to analyse the outcomes of AVF in elderly patients (&gt;60 years). Method Retrospective study was conducted in the Department of Nephrology at Sir Ganga Ram Hospital, New Delhi. Patients of more than 60 years of age in whom AVF was created from 1st January 2012 to 31st December 2016 were included in the study. Follow-up data of 3.5 years was analysed. The primary endpoint was to assess primary and secondary patency rates. Results A total of 300 patients were included in the study. The mean age was 63.8 years. Radiocephalic AVF (RCAVF) was the most common site of [69.8% (n = 210)], followed by brachiocephalic (BCAVF) in 25.2% (n = 75) and basilic vein transposition (BVT) in 5% (n = 15). At 12 months, overall survival of the AVF was 66.8%. At 42 months, the primary patency rate of RCAVF, BCAVF, and BVT was 50.6%, 52.6%, and 50.4% respectively. The commonest cause of access failure was thrombosis (20.4%) followed by non-maturation (9%). Vascular access abandonment was found least in BCAVF. Conclusion AVF remains the preferred vascular access for haemodialysis in the elderly population. Brachiocephalic AVF has higher primary and secondary patency rates. Thrombosis and failure of maturation are major concerns in the elderly AVF.

Purpose: This study was performed to retrospectively assess the efficacy of percutaneous creation of an intervascular bypass with or without stent graft deployment (endovascular bypass) for salvage of abandoned vascular access sites in hemodialysis catheter-consigned patients. Methods: Salvage of abandoned vascular access sites was attempted in 16 patients with hemodialysis catheters. These vascular access sites were salvaged using endovascular bypass techniques to redirect the access flow to a nonarterialized vein as a new outflow conduit or cannulation segment. The postintervention primary, assisted primary, and secondary patency rates of the access site and bypass were calculated using the Kaplan–Meier method. Results: The procedural and clinical success rates were both 100%. The postintervention primary patency rate of the bypass and access site at 360 days was 75.7 ± 12.5% and 56.8 ± 14.9%, respectively. The mean follow-up period was 461.9 days (range: 121–900 days). No major complications were observed. One bare bypass tunnel rupture and one pseudoaneurysm were noted during the procedure. Conclusion: Salvage of abandoned vascular access sites for hemodialysis catheter-consigned patients can be technically feasible and clinically successful using endovascular bypass techniques in selected patients when surgical revision is not considered or is not possible.

Aim.For patients who have exhausted cephalic vein arteriovenous fistula (AVF) options, controversy exists on whether brachial-basilic AVF with transposition (BBTAVF) or a forearm arteriovenous graft (AVG) should be the next vascular access of choice. This study compared the outcomes of these two modalities.Methods.A retrospective study of 122 Asian multiethnic patients who underwent either a BBTAVF (81) or an AVG (41). Maturation time and intervention rates were analyzed. Functional primary, secondary, and overall patency rates were evaluated.Results.The maturation time for BBTAVFs was significantly longer than AVGs. There was also a longer deliberation time before surgeons abandon a failing BBTAVF compared to an AVG. Both functional primary and secondary patency rates were significantly higher in the BBTAVF group at 1-year follow-up: 73.2% versus 34.1% (p<0.001) and 71.8% versus 54.3% (p=0.022), respectively. AVGs also required more interventions to maintain patency. When maturation rates were considered, the overall patency of AVGs was initially superior in the first 25 weeks after creation and then became inferior afterwards.Conclusion.BBTAVFs had superior primary and functional patency and required less salvage interventions. The forearm AVG might have a role in patients who require early vascular access due to complications from central venous catheters or with limited life expectancy.

Many studies have investigated the influence of diabetes mellitus (DM) on outcomes in patients with peripheral artery disease (PAD). We performed a meta-analysis of the outcomes of PAD treatments in DM patients compared with those without DM. Long-term mortality was the primary endpoint. Secondary endpoints were in-hospital/30-day mortality, primary/secondary patency, amputation, and limb salvage. Thirty-one studies reporting 58113 patients were eligible for enrollment. The mean follow-up duration ranged from 1 to 89 months. DM was significantly associated with long-term mortality (relative risk (RR) = 1.67; 95% confidence intervals (CI), 1.43–1.94; P < .001). DM was also associated with significantly lower primary patency (RR = 0.74; 95% CI, 0.58–0.95; P = .001) and secondary patency (RR = 0.80; 95% CI, 0.67–0.96; P = .009). DM is associated with worse outcomes and adverse prognosis of treatment in patients with PAD, and may therefore be a modifiable risk factor for poor prognosis in PAD patients.

Introduction: The forearm basilic vein can serve as an option for haemodialysis access but may not be possible in cases where the wrist arteries are unsuitable. In this setting, the forearm basilic vein can be used in a looped transposition with a brachial artery anastomosis. Aims: The aims of this study were to assess the outcome of forearm basilic vein looped transposition as an option for vascular access. Material and methods: Data from January 2007 to December 2010 were prospectively collected and analysed. Outcome measures were operative success, complications, maturation and primary and secondary patency following 5 years of follow-up. Results: From a total of 583 patients receiving autologous vascular access for haemodialysis, 24 (4.1%) underwent a forearm basilic vein looped transposition. The median age was 60 years (range, 27–80 years), with a slight male predominance (13 male:11 female). Mean follow-up was 34 months (1–60 months). Two patients died and other three were transplanted with subsequent fistula closure. All procedures were successful (100%); however, maturation failure occurred in one case (4.2%). No serious perioperative complications were observed. In two cases, we observed late false aneurysm formation requiring intervention. Primary patency at 1, 2, 3 and 5 years was the following: 77%, 62%, 21% and 10%, whereas secondary patency was the following: 81%, 71%, 61% and 32%, respectively. Conclusion: Autologous forearm basilic vein looped transposition is an effective surgical procedure for the creation of access for haemodialysis. This may be a useful option in patients with compromised peripheral arterial diameter or flow and should be considered in patients with a suitable forearm basilic vein.

Introduction The saphenous vein is commonly used as a vascular graft in peripheral artery surgery but rarely used for vascular access. The literature on straight configuration saphenous vein transposition to the popliteal artery is scarce. Here we present two cases of straight configuration saphenous vein transposition to the popliteal artery for vascular access, the surgical technique and respective follow-up. Case report Two young men, aged 29 and 36 years, were chosen for lower-limb vascular access for hemodialysis. The first patient was paraplegic since birth. He used his arms to move so upper extremity vascular access was avoided. The second patient presented with an infected upper extremity arteriovenous graft (AVG) and after multiple closed AVFs he had no more available arm veins. Both patients received autologous lower extremity straight configuration saphenous vein transpositions to the popliteal artery under spinal anesthesia in May and October 2012, respectively. Cannulation of the fistula was allowed after one month. There were no early complications. Slight swelling on the leg appeared in one of the patients. Both fistulas were still functional after 36 and 32 months, respectively. Conclusions The straight configuration saphenous vein transposition to popliteal artery is simple to perform, offers a long and straight segment for cannulation and may be a suitable autologous vascular access in selected patients.

Purpose: To evaluate the 36-month technical and clinical outcome after implantation of the 25-cm Viabahn endoprosthesis with Propaten bioactive surface in TransAtlantic Inter-Society Consensus II C and D lesions of the superficial femoral and proximal popliteal arteries. Materials and Methods: This prospective, multicenter, single-arm trial ( ClinicalTrials.gov; identifier NCT01263665) enrolled 71 patients (mean age 66.7±8.3 years; 50 men) with lifestyle-limiting claudication or rest pain (Rutherford category 2–4) and long (>20-cm) lesions of the superficial femoral and proximal popliteal arteries. Primary endpoint was primary patency at 36 months. Secondary endpoints included primary assisted patency; secondary patency; freedom from target lesion revascularization (TLR); freedom from a composite of death, target vessel revascularization (TVR), and amputation; clinical success; and freedom from device fracture. Results: Primary patency estimated by Kaplan-Meier analysis was 40.6% at 36 months. Primary assisted patency and secondary patency estimates were 53.0% and 96.9%, respectively. Within 36 months, 27 patients had to undergo a TLR. Twenty-five patients (35.2%) had a TVR. Freedom from the composite of death, TVR, and amputation endpoint was 44.5%. The estimate of the sustained clinical success with stable or improved Rutherford category was 58.5%. No stent fracture was detected during follow-up. Conclusion: The primary patency rate without reintervention after treatment of long femoropopliteal lesions is low. However, secondary patency after implantation of a Viabahn endoprosthesis is high and seems to be superior to the use of other revascularization techniques, resulting in persistent clinical improvement.
