WELCOME MESSAGE

First of all, I’d like to extend a warm welcome and ‘thank you’ for your interest in

DASy (Dialysis Access Synergy) 2020. I recognize that your time is valuable and

I’m seriously flattered that you chose to join us for this online event. In

successive to previous DASy meetings, we had recruited many experts from

different specialties to share and discuss on their experience in the care of

dialysis access related problems.

Due to the recently tense situation of Coronavirus epidemic episodes in different

areas, we had to adopt necessary transformation of the conference event. We

had taken advantage of the modern information technology to make DASy2020

possible in a teleconference format. Although the pneumonia epidemic had

prevented the traveling of our faculty and delegates to Taiwan this year, we hope

that the internet technology will make the event as informative and fruitful for all

the cyber participants.

With the strongest backup from SoDAS (Society of Dialysis Access Specialist),

TAVAH (Taiwan Association for Vascular and Access Health) endeavors to send

you only the best content regarding access management in this unprecedented

international online event. Hopefully we are able to provide you with practical

tips you can utilize to improve your future clinical practice. With the constant

effort, all of us may provide better patient care for dialysis access worldwide.

In the meantime, I encourage all of you actively take part in the online events. I’d

love to hear from you about what you’ve heard during DASy 2020, and what

you’re interested in in future events to come. I promise we will try our best to

ponder on your precious feedback and take action in our future events.

Again, I sincerely thank you for your attention to DASy with best regards.

Po Jen Ko MD

Chairman of DASy 2020

Name: Mr. Benjamin Lim

Abstract (Introduction, Methods, Results, Discussion)*

Background and Objectives

Arteriovenous grafts (AVG) are commonly used for haemodialysis access. Graft

thrombosis is one of the common complications arising from the use of AVGs, and can

lead to significant patient morbidity. Several modalities such as percutaneous thrombolysis,

or open surgical thrombectomy can be used for graft salvage. The purpose of this study is

to retrospectively compare outcomes between surgical thrombectomy and percutaneous

thrombolysis for the salvage of thrombosed upper limb AVGs.

Methods

A retrospective review of all patients who underwent salvage of thrombosed AVGs from

January 2014 to December 2018 was performed. Electronic medical records were

reviewed and data pertaining to patient demographics, comorbidities, AVG characteristics,

prior AVG interventions, current AVG intervention and procedural outcomes were collected.

Data analysis was performed using SPSS version 23. Dichotomous outcomes were

represented in percentages and compared using the independent T-test, whilst

continuous outcomes were represented in mean and compared using the Chi-square test.

Time to event outcome measures such as the 12-months primary and secondary patency

rates were represented as Kaplan-Meier curves and compared using the Log-rank test.

Multivariate analysis was further performed using the Cox regression model to adjust for

covariates. P values of less than 0.05 were taken to be statistically significant.

Results

A total of 222 salvage procedures (112 open thrombectomy and 110 percutaneous

thrombolysis) was performed. There were no significant differences between patient

demographics, antiplatelet and anticoagulation use, and graft characteristics. There was

no difference in procedural success rates (93.8% vs. 91.8%, p=0.578), or post-procedural

complications such as bleeding (3.6% vs. 2.7%, p=0.719), surgical site infection (2.6% vs.

1.8%, p=0.666). There was a trend towards more distal embolism in patients who

underwent percutaneous thrombolysis compared to open thrombectomy (2.7% vs. 8.2%,

p=0.070), although this was statistically not significant. There was also no difference in

the 12-month primary patency (log-rank 0.42) and secondary patency rates (log-rank 0.59)

between both group of patients.

Conclusion

The outcomes of open thrombectomy and percutaneous thrombolysis for salvage of

thrombosed upper limb AVGs are comparable, although there seems to be a trend

towards higher rates of distal embolism in patients who underwent percutaneous

thrombolysis.

Name: Dr. Lenny Suryani Safri

Abstract (Introduction, Methods, Results, Discussion)*

Methodology

This is a retrospective cohort study done in a single centre. Included were symptomatic

central venous obstructions' patients with positive central venogram following

arteriovenous fistula surgery. The end of the follow up was fixed at one year after CVO was

detected.

Result

Out of 89 patients who had positive central venogram, only 42 patients were identified as

first occurrence. Of the 42 patients; 45.2% were aged >65 years, 85.7% were diabetic,

95.2% were hypertensive, and 26.2% had hyperlipidemia. Total of 16 patients (38.1%)

developed mild central venous occlusion. 5 patients (11.9%) had severe central venous

stenosis and the remaining were classified as total occlusion of central veins. The primary

patency rates calculated according to survival analysis were 73% during the first 3 months

and 42% at one year. Bivariate analysis revealed that the factor affecting the primary

patency rate of AVF is left brachiocephalic vein lesion (P=0.034). However, there were no

other significant differences between the demographic factor (gender, age) and clinical

factors (comorbids, habit, antiplatelet usage, steroid usage, indwelling central venous

catheter) in relation to the CVO severity and the primary patency rate of AVF (P>0.05).

Discussion

The AVF patency, CVO severity and the contributing factors help in determining the

high-risk population to develop CVO that may eventually cause vascular access failure.

Our study showed that patients who develop CVO had the primary patency rate of 73%

during the first 3 months, 56% at 4th to 6th month and 41% at one year. We found a factor

that significantly decreases the primary patency: CVO at left brachiocephalic fistula

(P=0.034). The secondary patency rate was 78% during the first 3 months, 76% at 4th to

6th month and 66% at one year. The primary and secondary patency rates in our setting

were found to be lower in comparison to those reported by other authors . We postulated

that this could be due to the generally smaller veins size in our population that are known

to effect AVF patency.

In our study, demographic factors such age and gender did not influence the AVF patency

rate and CVO severity. Additional to this, we also found that the patients' comorbidities did

not have a significant effect on both outcomes. Other studies showed that diabetes

mellitus has significant correlation with AVF patency. However, in our study, we found no

significant correlations between diabetes mellitus with the AVF patency. This may be due

to proper optimization of glycemic control in our diabetes patients.

Conclusion

Central venous obstruction is a common problem occurring in patients with history of

indwelling central venous catheter. Location of lesion at the left brachiocephalic vein are

shown to have significant association with primary patency rate of fistula (P<0.05)

Abstract (Introduction, Methods, Results, Discussion)*

Single-Institution experience with Surfacer, an inside-out device, together with HeRO graft

for salvage of vascular access in the challenging patient

The Surfacer Inside-Out Access Catheter System (Surfacer) is a novel approach to restore

access in central venous complete total occlusions (CTO). We report a series of 3 cases

from November 2018 to December 2019 in our institution where this technique was used

in tandem with Hemodialysis Reliable Outflow (HeRO) graft for salvage of vascular access

in patients with central CTO.

The Surfacer device is a stiff cannula loaded onto a 180cm long guidewire with a sharp tip

and deflectable needle guide. It is introduced through an 8Fr sheath in the femoral vein to

the level of occlusion. Under fluoroscopic guidance, the trajectory of the needle guide is

aligned with the target skin exit site. The sharp recanalization wire is advanced through the

needle guide and exteriorised. Using the established through-and-through wire access, a

peel-away sheath is introduced across the occlusion. A graft is then anastomosed to the

brachial artery or a pre-existing arterialised fistula. Angioplasty of the SVC is performed

followed by insertion of the venous outflow component (VOC) which is then connected to

the graft using a SuperHeRO adapter.

All 3 patients had failed prior conventional attempts at CTO crossing and had exhausted

most conventional vascular access methods. Patients B and C were already on femoral

catheters and patient A had recurrent CTO despite multiple interventions. The above

technique yielded a 100% success rate with mean operative time of 140 minutes (A=98,

B=119, C=205). Cannulation rate was 100% with all undergoing successful early

cannulation by post-operative day 3 (A=1, B=2, C=3). Post-operative complication was

seen in patient A who developed a hematoma from cannulation on POD7 requiring

evacuation. Post-operative thrombosis rate was 33% with patient B having a partially

thrombosed graft 3 months post-operatively requiring thrombolysis. No subsequent

access interventions were required for patients A and C. All vascular access remained in

use up to the time of writing with the longest dwell time of 9 months in patient A.

The Surfacer device used together with HeRO graft is a feasible technique to avoid

catheter femoral dependence in patients where conventional attempts to cross the central

CTO have failed.

Single Stage Basilic Vein Transposition - An Effective and Viable Autogenous Access for

Dialysis

Introduction

The National Kidney Foundation’s / Kidney Disease Outcomes Quality Initiative

recommends autogenous arteriovenous fistulas (AVF) as the preferred method for long

term hemodialysis access. Basilic vein transposition is an alternative in patients with failed

AV access. Several studies have shown better patency rates, cost-effectiveness and

fewer complications of autogenous access over prosthetic arteriovenous grafts.

Aims

To analyze patency, complication rates and outcomes of single stage basilic vein

transposition.

Materials & Methods

A single-center retrospective non-randomized study conducted in MS Ramaiah medical

college, Bangalore from Jan 2015 to December 2018. A total of 72 consented patients who

underwent single stage basilic vein transposition were included in the study. All the

surgeries were done in a single stage under regional anesthesia. All the complications,

patency rates were calculated at the end of 1 year. Statistical analysis was performed

using the Chi-square test and patency rates assessed using the Kaplan Meir survival

curve.

Results

A total of 72 single-stage BVT was performed. 44 patients had a previous failed forearm

autogenous access and 28 had either absent or thrombosed cephalic vein in the arm. The

mean age was 56.6yrs with 59.57% males. The mean basilic vein and brachial artery

diameter were 3.6mm and 3.8mm respectively. The primary patency rate at 1 year was

84%. Edema and thrombosis were the most common complication in our study.

Discussion

Single-stage basilic vein transposition is a feasible surgical option in end-stage renal

disease patients and provides durable autogenous access with reasonable patency and

fewer complication rates.

Abstract (Introduction, Methods, Results, Discussion)*

Introduction

Stents are commonly deployed during endovascular maintenance or salvage of

dysfunctional haemodialysis access. Indications for stenting include immediate or early

lesion recoil or access perforation. In this study, we aim to investigate the effect of residual

lesion waisting on early outcomes after stenting.

Methods

A retrospective review of all endovascular procedures for the purpose of dialysis access

maintenance and salvage from 1st January 2016 to 30th June 2018 performed in a single

tertiary hospital was conducted. Patients who had stenting performed in the same

procedure after balloon angioplasty for the treatment of an occlusive or stenotic lesion

were identified. Electronic medical records were reviewed and relevant data such as

patient demographics and haemodialysis access characteristics were extracted. The

primary endpoint was freedom from clinically driven target lesion revascularization at

12-months (CD-TLR). Angiographic images were reviewed and patients were stratified

based on the presence of complete lesion effacement or residual lesion waisting after

balloon angioplasty prior to stent deployment. Statistical analysis was performed using

SPSS version 23.

Results

Stenting after balloon angioplasty was performed for a total of 31 patients. Univariate

analysis demonstrated that freedom from CD-TLR at 12-months for patients with

complete lesion effacement is significantly higher at 40.9%, as compared to 11.1% if there

is residual lesion waisting after balloon angioplasty (p=0.009, log-rank test). Multivariate

analysis using Cox regression accounting for potential confounders such as access type

and stent type showed that complete balloon effacement was associated with a trend to

higher freedom from CD-TLR at 12 months (HR 2.3; 95% CI 0.85-6.45; p=0.099).

Conclusions

Stent deployment should ideally be performed when complete balloon effacement of the

stenotic lesion can be achieved to ensure good outcomes. Stenting in the presence of

residual stenosis, as manifested by persistent balloon waisting, is associated with

increased re-interventions.

Short-term outcomes of surgical residents compared with attending surgeons in the

creation of autogenous haemodialysis arteriovenous fistulae

Reuban D'cruz, Benjamin JH Lim, Andrew MTL Choong, Jun Jie Ng

Introduction

Hands on surgical training is important in the training and nurturing of young surgical

residents. However, there is still ongoing debate about the influence of experience or

seniority on surgical outcomes. In this study, we aim to evaluate the short-term outcomes

between surgical residents and attending surgeons in the creation of autogenous

haemodialysis arteriovenous fistulae (AVF).

Methods

A retrospective review of all patients who underwent upper limb AVF creation in a 3-year

period from 2016 to 2018 was performed. Electronic medical records were accessed and

reviewed. Patients were stratified into two groups according to the status of the main

operative surgeon, and comparison of patient demographics, operative time and AVF

maturation parameters were performed.

Results

A total of 590 AVF created from 1st January 2016 to 31st December 2018 were included in

this study. The majority of AVF were created by experienced surgeons (N=434, 73.6%),

whereas the rest were created by surgical residents under direct supervision of the

attending surgeons (N=156, 26.4%). There were no differences in patient demographics.

Surgical residents had a significantly longer operative time as compared to attending

surgeons (72.4 mins vs. 66.1 mins, 95% C.I. -10.9 to -1.7, P = 0.007). However, between

surgical residents and attending surgeons, there was no difference in the proportion of

fistulas that have successfully matured within 6 months (75.7% vs. 72.7%, P=0.447), and

no difference in the average time to maturation (105 days vs. 101 days, 95% C.I. -18.9 to

10.0, P = 0.542).

Conclusions

There is no difference in short-term maturation outcomes in the creation of autogenous

haemodialysis by surgical residents or attending surgeons, although the operative time

taken for surgical residents was significantly longer.
