Vascular ultrasonography for follow-up of endovascular repair of abdominal aorta aneurysms
Conclusions Vascular ultrasonography is an excellent primary method for evaluation and post-surgical follow-up of patients treated with endovascular repair of abdominal aorta aneurysms. However, when ultrasonography detects problems or is difficult to accomplish, it should be supplemented with a more specific investigation for diagnostic confirmation. Contexto As informações sobre o seguimento de pacientes submetidos à correção endovascular de aneurisma de aorta abdominal com ultrassonografia vascular no Brasil são escassas, bem como sua comparação com os resultados obtidos com a angiotomografia. Na medida em que a...

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 (...

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.

Early diagnosis of atherosclerosis with panoramic radiographs: a review
The objective of this study is to highlight the importance of panoramic radiographs for diagnosis of arterial disease, by means of a bibliographic review. The PubMed database was searched using the keywords “ atherosclerosis ” and “ panoramic ” , with the filters “ last 5 years ” and “ humans ” . Twenty articles were identified, six of which were chosen for this study because they were open access. The review concluded that panoramic radiographs enable early diagnosis of carotid artery calcification, resulting in earlier interventions, and offer an accessible cost.Resumo Doen ças das artérias carótidas e...

Abnormal origin of posterior circumflex humeral artery and subscapular artery: case report and review of the literature
Abstract The subscapular, anterior circumflex, and posterior circumflex arteries arise from the third part of the axillary artery. During dissection of the right upper limb of the cadaver of a 70-year-old male, a common trunk was observed arising from the third part of the axillary artery which, after traveling for 0.5 cm, bifurcated into subscapular and posterior circumflex humeral arteries. The common trunk was crossed anteriorly by the radial nerve. The medial nerve was formed by medial and lateral roots on the medial side of the third part of the axillary artery, remaining medial to the brachial artery up to the cubita...

Increased Peripheral Arterial Calcification in Patients Receiving Warfarin Vascular Medicine
Conclusions
Warfarin use is associated with lower extremity arterial calcification in both men and women independent of age, sex, diabetes status, and other patient characteristics. This may have implications for the choice of therapies for long-term anticoagulation.

Syndromes Associated with Vascular Tumors and Malformations: A Pictorial Review Multisystem Radiology
Use of the International Society for the Study of Vascular Anomalies (ISSVA) classification system has been strongly recommended in recent years because of the need for separate therapeutic measures for patients with vascular tumors and malformations. In the ISSVA classification system, vascular tumors, which are neoplastic, are distinguished from vascular malformations, which are caused by vascular structural anomalies and are not neoplastic, on the basis of the presence or absence of neoplastic proliferation of vascular endothelial cells. It is important that radiologists be familiar with the development, diagnosis, and ...

Imaging of Vascular Complications and Their Consequences Following Transplantation in the Abdomen Multisystem Radiology
This article includes a basic description of the standard surgical techniques performed in the abdomen, with emphasis on the relevant vascular anastomotic reconstructions used. Posttransplantation complications can be broadly classified as vascular or nonvascular in origin. Many of these complications can be accurately depicted and characterized at imaging and dealt with definitively by using interventional radiology techniques, which can be graft- and life-saving and can obviate further complex surgical intervention. The article discusses imaging appearances of vascular complications and their consequences after transplan...

A novel technique of reimplantation of a radial artery that makes a hairpin turn to reduce the excessive vascular access flow in a dialysis patient.
We report a new technique called "reimplantation of an artery with a hairpin turn (RAHT)" to reduce excessive vascular access flow. A 73-year-old woman on dialysis consulted us for vascular surgery because of an increased cardiac preload. Chest radiography and echocardiography revealed an excessive shunt flow in the brachial artery (flow rate, 2336 mL/min). Vascular echo-Doppler of the left upper limb showed that the radial artery made a hairpin turn at the arteriovenous fistula (diameter, 9 mm). Diameters of the radial artery proximal and distal to the arteriovenous fistula were 5.4 and 3.7 mm, respectively. We ligated an...

Intracavitary electrocardiography-guided positioning of central vascular access device can spare unnecessary ionizing radiation exposure in pediatric patients.
CONCLUSION: When electrocardiography-guided positioning is uneventful and a valid P-Wave pattern is seen, postprocedure radiograph imaging for verification is unnecessary. Any effort should be made to upgrade hospital policies according to evidences and newest guidelines to spare pediatric patients harmful exposure to radiation by limiting the use of radiography only to selected cases.

Image-guided Intervention in Management of Complications of Portal Hypertension: More than TIPS for Success Vascular/Interventional Radiology
Management of clinically important sequelae of portal hypertension, such as variceal bleeding and ascites, may involve a combination of medical, endoscopic, surgical, and interventional approaches and procedures. Although clinically significant esophageal and rectal varices are typically visible endoscopically, ectopic varices may require multiplanar portal venous phase computed tomography or magnetic resonance imaging for diagnosis. A detailed understanding of individual vascular anatomy, flow dynamics, and patient-related factors such as cardiac and hepatic status is necessary for appropriate treatment selection in patie...

Preclinical evaluation of the InCraft(R) aortic endograft in a sheep model.
Abstract
Animal models remain the gold standard for the preclinical evaluation of tissue response, sealing and integrity of aortic endografts. Preclinical testing of the InCraft(®) device was performed to evaluate these attributes. Through the femoral arteries of eight male crossbred sheep, 22 mm diameter InCraft(®) Aortic Bifurcate devices were deployed in the abdominal aortas, and shortened 13 mm diameter iliac limbs were deployed in the right iliac arteries. Vessels were excised for radiographic and histopathologic assessment at six months. There were no instances of graft thrombosis, type I endoleak or endog...

Endovascular aortic repair with EndoAnchors demonstrate good mid-term outcomes in physician-initiated multicenter analysis-The PERU registry.
CONCLUSIONS: This real-world registry demonstrates that adjunct EndoAnchor usage at EVAR achieves high rates of freedom from type IaEL at mid-term including in a high number of patients with hostile neck anatomy, with positive trends in sac-size evolution. Further data with longer follow-up may help to establish EndoAnchor usage as a routine adjunct to EVAR, especially in hostile necks.
