The impact of technology on treatment of iatrogenic cervicothoracic vascular traumas: a study of two cases three decades apart and a review of the literature
Resumo Complica ções relacionadas ao acesso venoso cervicotorácico, como os pseudoaneurismas (PAs), podem ser devastadoras. Neste artigo, apresentamos dois casos semelhantes em que o avanço tecnológico impactou no diagnóstico, tratamento e resultados. Ambos pacientes apresentaram volumoso PA após a tentativa de punção venosa profunda. O primeiro caso, em 1993, diagnosticado por duplex scan, revelou grande PA oriundo da artéria subclávia direita. A artéria foi abordada por esternotomia mediana com extensão supraclavicular. O PA originava-se do tronco tireocervical, tratado com simples ligadura. No segundo caso,...

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.

Transradial approach for challenging vascular access interventions.
CONCLUSION: The transradial approach for vascular access endovascular interventions is technically feasible and safe. It allows simultaneous treatment of peri-anastomotic lesions in fistulas with complex venous anatomy as well as lesions in the arterial inflow and central outflow.

Sutureless open vascular anastomosis connector: An experimental study.
The objective of this study was to assess the safety of a new developed sutureless vascular adapter system in a porcine model. In five pigs, 4-cm-long polyester prosthesis (6 mm diameter) were implanted and anastomosed with the newly developed adapter proximally and suture anastomosis distally. The integration of the adapter was investigated in comparison to the suture anastomosis. These investigations were performed by light microscopy and scanning electron microscopy. Median operative time for performing the adapter anastomosis was significantly shorter compared to suture anastomosis (66 s vs. 246 s, p < 0.0...

Increased fluorodeoxyglucose activity of a vascular graft representing a potential pitfall of fluorodeoxyglucose positron emission tomography/computed tomography imaging
A 75-year-old man was found to have a right lung nodule on a chest radiograph that was suspicious for a lung malignancy. He was subsequently referred for an 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scan to evaluate the lung nodule. FDG PET/CT confirmed a solitary 1.1 cm spiculated lung nodule that was FDG-avid (maximum standardized uptake value [SUVmax], 6.3) in the posterior segment of the right upper lobe, suspicious for a primary lung malignancy (A and B, arrows). There was no evidence of nodal or distant disease. Incidentally, there was a distinct increase of FDG activity (...

Amplatzer vascular plug for occlusion or flow reduction of hemodialysis arteriovenous access
Conclusions: The results of this short preliminary study suggest that plug insertion for occlusion or for flow reduction in a hemodialysis AVA constitutes a reasonable alternative to coil insertion or to open surgery in selected patients.

Journal of Vascular Surgery – December 2017 Audiovisual Summary
We would like to tell you about the December issue of the Journal of Vascular Surgery and some of the key articles. The first paper, by Chandra and co-authors from Stanford, entitled “Management and outcomes of symptomatic abdominal aortic aneurysms during the past 20 years,” compares symptomatic patients with abdominal aortic aneurysm (AAA), defined as those who had new onset abdominal pain or aneurysm tenderness with no rupture found by computed tomography scan or in the operating room. In these patients, the repair of AAA was primarily open from 1995 to 2004 and evolved to primarily endovascular repair during the next decade.

Retrospective Study Comparing WBC scan and 18F-FDG PET/CT in Patients with Suspected Prosthetic Vascular Graft Infection
Prosthetic vascular graft infections (PVGIs) are associated with high mortality rates. To improve treatment outcome, an early and definite diagnosis is critical, and current diagnostic criteria are often insufficient. The accuracy of 2-deoxy-2-[fluorine-18]-fluoro-d-glucose positron emission tomography integrated with computed tomography (18F-FDG PET/CT) and white blood cell (WBC) scan for the diagnosis of PVGI were compared.

Pulmonary sequestration and endovascular treatment: a case report
We report the case of a 29-year-old-woman presenting with recurrent pneumonia for 5 years. A CT scan of the chest revealed poor vascular formation in the lower region of the right lung. The pulmonary sequestration was treated by embolization of the anomalous branch.

Tomographic anatomy of the vena cava and renal veins: features relevant to vena cava filter placement
CONCLUSIONS: The radiological correlation between the confluence of the more distal renal vein and vertebral bodies exhibits little variation, irrespective of the biotype of the patient. CONTEXTO: Há uma demanda crescente por procedimentos invasivos que abordam a veia cava inferior, especialmente o implante de filtros de veia cava. A identificação da veia renal mais caudal para a liberação segura do filtro nem sempre é fácil durante a cavografia. OBJETIVOS: Estabelecer parâmetros da relação das veias renais e da cava infrarrenal com o corpo vertebral correspondente, sua relação com a biotipologia, presença de ...

A pilot study comparing bovine mesenteric artery and expanded polytetrafluoroethylene grafts as non-autogenous hemodialysis options
Conclusions The L-Hydro graft appears to be a valuable alternative option for AVFs, since it seems to require fewer interventions to maintain patency when compared to ePTFE grafts.

Assessment of the pedal arteries with Duplex Scanning
Resumo A ultrassonografia vascular com Doppler é um método não invasivo útil no diagnóstico e planejamento terapêutico da doença oclusiva das artérias podais. A artéria pediosa dorsal é a continuação direta da artéria tibial anterior e tem trajeto retilíneo no dorso do pé, dirigindo-se medialmente ao primeiro espaço intermetatars iano, onde dá origem a seus ramos terminais. A artéria tibial posterior distalmente ao maléolo medial se bifurca e dá origem às artérias plantar lateral e plantar medial. A plantar medial apresenta menor calibre e segue medialmente na planta do pé, enquanto a plantar lateral...
