The long-term survival of patients on hemodialysis is often limited by the exhaustion of vascular access sites. A fundamental principle of vascular access surgery is that the arteriovenous (AV) access be placed as far distally in the arm as possible. This principle enhances the secondary patency of the AV grafts by preserving the proximal veins for AV graft revision and provides venous outflow for a new AV access to be placed more proximally in the extremity. The standard straight and looped AV graft configurations violate this principle by bypassing long segments of vein in the extremity that could be used for AV graft revision or new AV graft placement. We have developed a novel AV graft configuration that preserves venous outflow and enhances the longevity of each AV access site. The purpose of this review is to describe the reverse J AV graft technique and to report our outcomes with the procedure. Between February 2004 and April 2007, 26 AV grafts were placed using the reverse J configuration. Eighteen (69%) AV grafts were placed in the upper arm, 7 (27%) were placed in the forearm, and 1 (4%) was placed in the thigh. Median follow-up was 320 days. The secondary AV graft patency was 90 per cent at 6 months, 84 per cent at 12 months, and 84 per cent at 18 months. Five AV grafts were subsequently revised to a loop configuration. Overall patient survival was 85 per cent at 6 months, 68 per cent at 12 months, and 62 per cent at 18 months. Compared with the standard straight and looped AV graft configurations, the reverse J AV graft configuration preserves the length of venous outflow in the extremity for AV graft revision or new AV graft placement. Therefore, the reverse J configuration enhances the secondary patency of AV graft patency and AV access site longevity.

Observation Period

Introduction This retrospective study investigated the factors and the effects of different venous outflows on forearm arteriovenous graft patency. Methods The venous outflow sites included basilic, cephalic, median antecubital, and deep veins. Comparisons among multiple groups were analyzed. Findings A total of 179 patients with forearm loop arteriovenous grafts met the inclusion criteria. Of these, 72 were basilic, 48 were cephalic, 44 were median antecubital, and 15 were deep. The median observation period was 19 months. The survival rate was 84.9% at 24 months and 78.2% at 48 months. Primary, secondary, and assisted primary patency rates for all arteriovenous grafts were 48.9%, 72.4%, and 68.4% at 12 months; 13.8%, 33.9%, and 23.6% at 24 months; and 0.6%, 4.6%, and 2.3% at 48 months, respectively. Differences in primary patency were statistically significant compared with those of secondary and assisted primary patency ( P <  0.05). Primary patency rates for cephalic, median antecubital, basilic, and deep were 47.9%, 48.6%, 47.7%, and 40.0% at 12 months and 12.5%, 13.9%, 22.7%, and 0% at 24 months, respectively. Secondary patency rates for cephalic, median antecubital, basilic, and deep were 75.0%, 69.4%, 75.0%, and 73.3% at 12 months and 39.6%, 30.6%, 38.6%, and 13.3% at 24 months, respectively. There was no significant difference in primary thrombosis among basilic, cephalic, median antecubital and deep. There were no significant differences observed in primary or secondary patency rates among all the groups. Stenoses in the venous anastomosis and outflow vein were frequently observed in all types of arteriovenous grafts. Central venous stenosis was most commonly seen in deep (26.67%). On average, 1.9 interventions per patient were performed on the graft to maintain function. Conclusion Different venous outflow selections were not associated with long-term patency and the occurrence of thrombosis in hemodialysis forearm loop arteriovenous grafts.

Background: To evaluate safety, short and long-term graft patency, clinical success rates, and factors associated with patency, limb salvage and mortality after surgical reconstruction in patients younger than 50 years of age who had undergone unilateral iliac artery bypass surgery. Patients and methods: From January 2000 to January 2010, 65 consecutive reconstructive vascular operations were performed in 22 women and 43 men of age < 50 years with unilateral iliac atherosclerotic lesions and claudication or chronic limb ischemia. All patients were followed at 1, 3, 6, and 12 months after surgery and every 6 months thereafter. Results: There was in-hospital vascular graft thrombosis in four (6.1 %) patients. No in-hospital deaths occurred. Median follow-up was 49.6 ± 33 months. Primary patency rates at 1-, 3-, 5-, and 10-year were 92.2 %, 85.6 %, 73.6 %, and 56.5 %, respectively. Seven patients passed away during follow-up of which four patients due to coronary artery disease, two patients due to cerebrovascular disease and one patient due to malignancy. Limb salvage rate after 1-, 3-, 5-, and 10-year follow-up was 100 %, 100 %, 96.3 %, and 91.2 %, respectively. Cox regression analysis including age, sex, risk factors for vascular disease, indication for treatment, preoperative ABI, lesion length, graft diameter and type of pre-procedural lesion (stenosis/occlusion), showed that only age (beta - 0.281, expected beta 0.755, p = 0.007) and presence of diabetes mellitus during index surgery (beta - 1.292, expected beta 0.275, p = 0.026) were found to be significant predictors of diminishing graft patency during the follow-up. Presence of diabetes mellitus during index surgery (beta - 1.246, expected beta 0.291, p = 0.034) was the only variable predicting mortality. Conclusions: Surgical treatment for unilateral iliac lesions in patients with premature atherosclerosis is a safe procedure with a low operative risk and acceptable long-term results. Diabetes mellitus and age at index surgery are predictive for low graft patency. Presence of diabetes is associated with decreased long-term survival.

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.

Av Graft

As patient longevity on hemodialysis has increased, surgeons are increasingly challenged to provide vascular access to patients who have exhausted options for access in the upper extremity. A common operation performed on these patients has been the loop thigh arteriovenous (AV) graft based off the common femoral vessels. However, there are several disadvantages of placing prosthetic grafts in proximity to the groin. Our group has modified the thigh loop AV graft procedure by moving the anastomoses to the mid-superficial femoral artery and vein. The advantage of this location is that it preserves the proximal femoral vessels for graft revision and avoids the node-bearing tissue and overhanging panniculus of the groin. The purpose of this study was to review our technique, patient selection, and experience with the mid-thigh loop AV graft procedure. Between 2001 and 2003, 46 mid-thigh loop AV grafts were placed in 38 patients. Patient hospital, office, and dialysis clinic records were reviewed. The primary and secondary patency for AV grafts in this study by life-table was 40 per cent and 68 per cent at 1 year and 18 per cent and 43 per cent at 2 years. There were 10 infections (21%) requiring graft removal. Four patients underwent subsequent placement of a proximal loop thigh AV graft after mid-thigh graft failure. Patient survival was 86 per cent at 1 year and 82 per cent at 2 years. There were no patient deaths related to thigh graft placement. Our results with the mid-thigh loop AV graft compare favorably with published results for thigh loop AV grafts. The procedure preserves the proximal vasculature, permitting graft revision or subsequent proximal graft placement, and may be associated with fewer infectious complications. The mid-thigh loop AV graft procedure should be considered before placement of a thigh loop AV graft based off the common femoral artery and vein.

Background and Objectives: An increase in the incidence of end-stage renal disease (ESRD) is associated with the need for a wider use of vascular access. Although arteriovenous (A-V) fistula is a preferred form of vascular access, for various reasons, permanent catheters are implanted in many patients. Materials and Methods: A retrospective analysis of clinical data was carried out in 398 patients (204 women) who in 2010–2016 were subjected to permanent dialysis catheters implantation as first vascular access or following A-V fistula dysfunction. The factors influencing the risk of complications related to vascular access and mortality were evaluated and the comparison of the group of patients with permanent catheter implantation after A-V fistula dysfunction with patients with first-time catheter implantation was carried out. Results: The population of 398 people with ESRD with mean age of 68.73 ± 13.26 years had a total of 495 permanent catheters implanted. In 129 (32.6%) patients, catheters were implanted after dysfunction of a previously formed dialysis fistula. An upward trend was recorded in the number of permanent catheters implanted in relation to A-V fistulas. Ninety-two infectious complications (23.1%) occurred in the study population in 65 patients (16.3%). Multivariate analysis showed that permanent catheters were more often used as the first vascular access option in elderly patients and cancer patients. Mortality in the mean 1.38 ± 1.17 years (min 0.0, max 6.70 years) follow-up period amounted to 50%. Older age and atherosclerosis were the main risk factors for mortality. Patients with dialysis fistula formed before the catheter implantation had a longer lifetime compared to the group in which the catheter was the first access. Conclusion: The use of permanent catheters for dialysis therapy is associated with a relatively high incidence of complications and low long-term survival. The main factors determining long-term survival were age and atherosclerosis. Better prognosis was demonstrated in patients after the use of A-V fistula as the first vascular access option.

Arteriovenous Access

Introduction The quality of the life in patients requiring long term hemodialysis is directly proportional to the long-term patency of their vascular access. Basilic vein transposition for vascular access (BAVA) represents a suitable option for creating a tertiary native vascular access for hemodialysis on the upper extremities for patients requiring long term hemodialysis. The purpose of the study is to compare BAVAs with arteriovenous grafts (AVG). Method Data collection was based on selecting all of the patients with BAVA created in the time period in between January 1996 and August 2011. A questionnaire was created and sent to the selected hemodialysis centers. The resulting set of data was statistically analyzed and evaluated. Results In the time period between 1 January 1996 and August 2011, arteriovenous access for hemodialysis was created in 6754 patients (7203 procedures in total). Out of these patients, 175 BAVAs were created. Our patient database of those undergoing the BAVA procedure consisted of 98 females (56%) and 77 males (44%) with an average age of 64.5 years. The prevalence of diabetes mellitus was 60% (105 patients). Primary patency after 12 months was 68.8%, 24 months 59.7%, 36 months 53.8, 48 months 53.8%, and 60 months 50%. Primary assisted patency after 12 months was 89.9%, 24 months 84.6%, 36 months 77.8%, 48 months 77.9%, 60 months 70.8%. Secondary patency after 12 months was 89.4%, 24 months 86.9%, 36 months 81%, 48 months 78.9%, 60 months 75.7%. Twenty-nine BAVAs (16.5%) were obliterated. Conclusion Patients benefit from this type of procedure due to the longer patency of a native arteriovenous access, as well as a lower incidence of infectious complications.

The hemodialysis population continues to grow. Although procedures for dialysis have existed for over 60 years, significant challenges with vascular access to support hemodialysis persist. Failure of arteriovenous fistulas (AVFs) to mature, loss of AVF and graft patency, thrombosis and infection hinder long-term access and add extra health care costs as well as patient morbidity. There have been numerous innovations over the last decade aimed at addressing the issues. Herein, we review the literature and summarize the recent evolution of drug delivery, graft development, minimally invasive AVF creation, and stem cell therapy for hemodialysis access.

ObjectivesThe influence of the bleeding site on long-term survival after the primary percutaneous coronary intervention (PCI) is poorly understood. This study sought to investigate the relationship between in-hospital access site versus non-access site bleeding and very late mortality in unselected patients treated with primary PCI.MethodsData of the 2715 consecutive patients with ST-segment elevation myocardial infarction treated with primary PCI, enrolled in a prospective registry of a high volume tertiary centre, were analysed. Bleeding events were assessed according to the Bleeding Academic Research Consortium (BARC) criteria. The primary outcome was 4-year mortality.ResultsThe BARC type ≥2 bleeding occurred in 171 patients (6.3%). Access site bleeding occurred in 3.8%, and non-access site bleeding in 2.5% of patients. Four-year mortality was significantly higher for patients with bleeding (BARC type ≥2) than in patients without bleeding (BARC type 0+1), (36.3% vs 16.2%, p<0.001). Patients with non-access site bleeding had higher 4 year mortality (50.7% vs 26.5%, p=0.001). After multivariable adjustment, BARC type ≥2 bleeding was the independent predictor of 4 year mortality (HR 2.01; 95% CI 1.49 to 2.71, p<0.001). Patients with a non-access site bleeding were at 2-fold higher risk of very late mortality than patients with an access site bleeding (HR 2.62; 1.78 to 3.86, p<0.001 vs HR 1.57; 1.03 to 2.38, p=0.034).ConclusionsBoth access and non-access site BARC type ≥2 bleeding is independently associated with a high risk of 4-year mortality after primary PCI. Patients with non-access site bleeding were at higher risk of late mortality than patients with access site bleeding.
