Incidence of deep venous thrombosis and stratification of risk groups in a university hospital vascular surgery unit
CONCLUSION: The incidence of deep venous thrombosis in vascular surgery patients was 8.5%, which is similar to figures reported in the international literature. Most vascular surgery patients were stratified into the high and very high risk for deep venous thrombosis groups.CONTEXTO: Há lacuna de conhecimento sobre a real incidência de trombose venosa profunda nos pacientes submetidos a procedimentos cirúrgicos vasculares no Brasil. A atual pesquisa pretende corroborar a implementação de um sistema de vigilância e controle sobre a qualidade de profilaxia de tromboembolismo venoso em nosso meio. As investigações, em...

Peripherally inserted central venous catheters: alternative or first choice vascular access?
Conclusions Ultrasound-guided and fluoroscopy-positioned PICC placement had a low incidence of complications, reduced infection rates, and proved safe and effective in cases of difficult vascular access. PICCs can be considered the devices of choice for central vascular access.

Women in vascular surgery: a brief analysis of the Brazilian profile
Conclusions Despite the limitations of the study population, this preliminary study confirms the idea that female vascular surgeons demonstrate continuous dedication to practicing their specialty and sets a precedent so that further studies can investigate the professional practice of female vascular surgeons in greater detail, stimulating discussion of gender inequalities in medical practice.

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...

Anatomical variations of tibial vessels: differential diagnosis of deep vein thrombosis by vascular ultrasound
CONCLUSION: Although a rare condition, found in only 0.41% of the cases, awareness of posterior vein absence may help to avoid misdiagnoses and false-positive results of DVT in patients with this variation.

Profile of peripheral vascular changes in crack-cocaine addicts receiving treatment at a Psychosocial Care Center for Alcohol and Drugs
Conclusions Crack users exhibit peripheral vascular disorders. Length of time since starting to use the drug had the greatest impact on this system, suggesting an association between crack use and reduced arterial flow.

Technical evaluation of Exoseal-Cordis® vascular closure device
Conclusions In this study, hemostasis by manual compression exhibited equal efficacy to use of a VCD, but the duration of compression and delay before resumption of activity were shorter in the patients for whom the device was employed.

In-patient adult and pediatric vascular ultrasound: Distribution and rate of positive findings.
CONCLUSION: We had a higher yield of positive findings in the adult cases. We observed a higher proportion of more complex duplex exams in the pediatric cases suggesting that a higher level expertise is needed to perform the pediatric vascular duplexes.

Setting high-impact clinical research priorities for the Society for Vascular Surgery
With the overall goal of enhancing the effectiveness and efficiency of vascular care, the Society for Vascular Surgery (SVS) recently completed a process by which it identified its top clinical research priorities to address critical gaps in knowledge guiding practitioners in prevention and treatment of vascular disease. After a survey of the SVS membership, a panel of SVS committee members and opinion leaders considered 53 distinct research questions through a structured process that resulted in identification of nine clinical issues that were felt to merit immediate attention by vascular investigators and external fundin...

Results from the International Silver Graft Registry for high-risk patients treated with a metallic-silver impregnated vascular graft.
Abstract The purpose of this postmarket surveillance registry was to document the efficacy of a vascular prosthesis coated with metallic silver in high-risk patients undergoing vascular reconstructions. Patency (primary endpoint) and freedom from graft infection (secondary endpoint) data were assessed at a minimum of 12 months in patients with significant co-morbidity and/or confirmed graft infections or infected native vessels. Between November 2006 and December 2009, 230 patients with high-risk factors underwent aortic, peripheral and/or extra-anatomic reconstructions with Silver Graft(®) (SG) in six German, on...

Vascular graft thrombosis secondary to activated protein C resistance: a case report and literature review.
Abstract Hypercoagulability is a well-documented and prominent risk factor for venous thromboembolism. The role of thrombophilia in arterial thrombotic events is less well defined. A 52-year-old male patient with multiple atherogenic risk factors was admitted for non-healing pedal ulcer and absent distal pulses. Based on the clinical presentation, Doppler ultrasound and angiography findings, the patient underwent elective in situ bypass arterial reconstruction. The saphenous vein graft was of satisfactory quality and the procedure went routinely. Acute graft thrombosis on postoperative day 0 was recognized immedia...

A vascular laboratory protocol for improving and managing after-hours suspected acute deep venous thrombosis.
This study reviews the clinical and workforce impact of a suggested protocol designed for the management of suspected acute deep venous thrombosis (DVT) in patients seen after standard vascular laboratory business hours. The protocol included the use of Wells score, D-dimer and a single dose of therapeutic anticoagulant to defer venous duplex ultrasound (VDU) testing until routine business hours unless contraindicated. Information was collected on medical history, physical exam and the timing of any diagnostic studies and treatment provided. Over 15% of studies done after-hours were deemed unnecessary by our protocol and i...

Resident Views on Vascular Ultrasonography Education: A Canadian Perspective
With the requirement to obtain RPVI certification as of 2014 in American vascular surgery programs, formal vascular ultrasound (VUS) training is expected in vascular surgery training. Canadian programs, however, do not have the same credentialing requirements, and not all programs have formal VUS training. We sought to determine whether Canadian trainees desire additional VUS training, how this training should be delivered, and what role they see VUS playing in their future practice.

Routine Use of Ultrasound Guidance in Femoral Arterial Access for Peripheral Vascular Intervention Decreases Groin Hematoma Rates in High-Volume Surgeons
There is a documented learning curve when adopting ultrasound guidance (UG) to aid vascular access. In the Vascular Study Group of New England (VSGNE), routine UG during percutaneous femoral artery access was shown to protect against the complication of groin hematoma. We sought to confirm this finding in the Vascular Quality Initiative (VQI), a dataset with a larger sample size and broader geographic distribution, and evaluate the effects of ultrasound usage and interventionalist volume on hematoma rates following peripheral vascular interventions (PVI).
