The role of vascular echography in the management of complications associated with central venous access for hemodialysis in cancer patients: two case reports and literature review
Resumo O implante de cateter venoso central para hemodi álise é comumente realizado em grandes centros e suas complicações estão, por vezes, associadas ao treinamento insuficiente de quem o realiza, mas também às condições clínicas do próprio doente. O presente estudo relata dois casos de intercorrências relacionadas ao uso do cateter de curt a permanência para hemodiálise. No primeiro caso, houve inserção inadvertida da cânula na artéria subclávia esquerda e consequente trombose arterial, que foi conduzida conservadoramente, documentando-se uma boa perfusão colateral com ecografia vascular. O segundo c...

Anatomic variant of the internal jugular vein and its importance in vascular access for hemodialysis
Resumo A veia jugular interna direita é considerada a melhor via para um acesso vascular, devido a baixas taxas de complicação e ao fornecimento de fluxo satisfatório durante a hemodiálise dado seu trajeto mais retilíneo para o átrio direito. O presente estudo relata a identificação, prévia à punção, de uma variação anatô mica da posição da veia jugular interna em relação à artéria carótida comum. Destaca-se o benefício dessa identificação prévia, enfatizando-se a importância de se realizar a ultrassonografia vascular com Doppler em detrimento de utilizar somente reparos anatômicos externos par...

Variation in smoking cessation after vascular operations
Objective: Smoking is the most important modifiable risk factor for patients with vascular disease. The purpose of this study was to examine smoking cessation rates after vascular procedures and delineate factors predictive of postoperative smoking cessation.Methods: The Vascular Study Group of New England registry was used to analyze smoking status preoperatively and at 1 year after carotid endarterectomy, carotid artery stenting, lower extremity bypass, and open and endovascular abdominal aortic aneurysm repair between 2003 and 2009. Of 10,734 surviving patients after one of these procedures, 1755 (16%) were lost to fol...

Prevalence of Vertebral Fractures, Vascular Calcifications, and Mortality in Warfarin Treated Hemodialysis Patients.
Abstract Warfarin inhibits vitamin-K dependent proteins involved in bone mineralization and the prevention of vascular calcification (bone Gla protein BGP, matrix Gla protein MGP). In this multicenter, cross-sectional study with 3-year follow-up, data from 387 patients on hemodialysis for ≥1 year at 18 dialysis units were analyzed. Patients on warfarin treatment for > 1 year (11.9% of the population) were compared with the remaining cohort for vertebral fractures, vascular calcifications and mortality. Vertebral fractures and vascular calcifications were sought in L-L vertebral X-rays (D4 to L5). Compared wit...

Early experience with a novel self-sealing nanofabric vascular graft for early hemodialysis access.
CONCLUSION: AVflo self-sealing graft allows for early cannulation after implantation and thus may potentially eliminate the need for central venous catheters in selected patients. PMID: 26395367 [PubMed - as supplied by publisher]

Early Surgical Thrombectomy Improves Hemodialysis Vascular Access Salvage
Hemodialysis vascular access (HVA) salvage after acute thrombosis raises a debate between nephrologists and vascular surgeons regarding the urgency of treatment. To assess the impact of early surgical thrombectomy on the rate of HVA salvage, we offered an early surgical protocol to eligible patients with acute HVA thrombosis.

Who Treats Vascular Access Thrombosis and When? A Comprehensive Survey of All French Hemodialysis Centers
Vascular access thrombosis (VAT) is a severe complication that needs a timely treatment. The annual incidence of VAT and the timeliness of its treatment are not currently known.

Treatment outcomes and lessons learned from 5134 cases of outpatient office-based endovascular procedures in a vascular surgical practice.
CONCLUSIONS: Endovascular procedure can be performed safely in an office-based facility with excellent outcomes. Lessons learned in establishing office-based endovascular suites with efforts to reduce procedural complications and optimize quality patient care are discussed.

Interest of surgical vascular reconstructions aiming at preserving hemodialysis accesses
This study evaluated the effectiveness of the surgical vascular reconstructions made to preserve vascular accesses for hemodialysis and to study their benefit in terms of safeguarding of the venous capital, use of catheters, time before cannulation, as well as patency and postoperative morbi-mortality, by comparing them with the creation of a new access.

The Inside-Out Technique: A Vascular Surgeon's Guide to Complex Catheter Placement
Patients with multiple failed dialysis accesses and limited access sites can present a significant challenge to vascular surgeons. The presence of central venous occlusion and the need for temporary or permanent dialysis catheter placement are especially problematic. Previous reports have described an “inside-out” technique that avoids the need for subclavian or femoral catheter placement by placing a supraclavicular catheter through a percutaneous femoral vein. However, very few reports of its use in vascular surgery exist.

NuSpun Vascular Graft: Using Nanotechnology That Mimics Nature for Hemodialysis Access
Current arteriovenous grafts (AVGs) have unacceptably high failure rates. This issue led to the development of tissue-engineered vascular grafts in an attempt to mimic a native blood vessel. We hypothesized that a novel synthetic vascular graft could be developed using electrospinning technology that functions as scaffolding for cell ingrowth, thereby providing the added natural protection of native cells against thrombosis and infection. The resulting graft would also maintain the strength, kink resistance, and safety with cannulation that standard synthetic AVGs provide.
