Brazilian multicenter study of 71 patients with juvenile-onset Takayasu's arteritis: clinical and angiographic features

Rev. bras. reumatol; 56 (2), 2016
ABSTRACT Objective: To describe the clinical and angiographic characteristics of Takayasu's arteritis in Brazilian children and adolescents. Methods: A retrospective data collection was performed in 71 children and adolescents followed in 10 Brazilian reference centers in Pediatric Rheumatology. The ev...

Dilatation of common iliac arteries after endovascular infrarenal abdominal aortic repair with bell-bottom extension

Abstract Objective: Endovascular techniques to treat abdominal aortic aneurysms results in lower morbidity and mortality rates. However, dilation of the common iliac arteries prevents adequate distal sealing, which compromises the procedure success. The aim of this study is report the long-term outcomes...

Is age a determinant factor in evar as a predictor of outcomes or in the selection procedure? our experience

Abstract Introduction: Endovascular aneurysm repair (EVAR) is the therapy of choice in high risk patients with abdominal aortic aneurysm. The good results described are leading to the broadening of clinical indications to younger patients. However, reintervention rates seem higher and even with successf...

Endovascular treatment of internal iliac artery aneurysms: single center experience

Abstract Objective: Internal iliac artery aneurysms (IIAA) are rare, representing only 0.3% of aortoiliac aneurysms. Its treatment with open surgery is complex and associated with high morbidity and mortality, which led to increasing application of endovascular solutions. In this study, we aimed to eval...

Advances in the endovascular treatment of direct carotid-cavernous fistulas

SUMMARY Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus. They are considered direct when there is a direct connection between the internal carotid artery and the cavernous sinus. These cases are generally traumatic. Direct CCFs are high-flow l...

Long-term efficacy of endovascular vs open surgical repair for complicated type-B aortic dissection: a single-center retrospective study and meta-analysis

Braz. j. med. biol. res; 49 (6), 2016
This study aimed to evaluate the long-term survival and risk factors of traditional open surgical repair (OSR) vs thoracic endovascular aneurysm repair (TEVAR) for complicated type-B aortic dissection (TBAD). A total of 118 inpatients (45 OSR vs 73 TEVAR) with TBAD were enrolled from January 2004 to Janu...

Giant Pseudoaneurysm as a delayed Surgical Complication in a Patient Operated on a Giant Neuroma of the Vagus Nerve: Case Report and Management Considerations

Arq. bras. neurocir; 34 (4), 2015
The vertebral artery has four segments. The horizontal portion of the V3 segment is the most exposed portion of the vertebral artery to potential iatrogenic injuries during surgical approaches to the posterior fossa.We present an unusual case of a patient who was operated on a giant neuroma of the left v...

Tratamiento endovascular exitoso de aneurisma de aorta torácica secundario a infección de catéter de arteria umbilical en un recién nacido pretérmino

Rev. chil. pediatr; 86 (5), 2015
Los aneurismas aórticos en la población pediátrica son poco frecuentes. El uso de catéteres de arteria umbilical en neonatos se ha asociado a infección y en algunas oportunidades a formación de aneurismas aórticos. La reparación quirúrgica de estos aneurismas es una forma de terapia; sin embargo...

Unfavorable iliac artery anatomy causing access limitations during endovascular abdominal aortic aneurysm repair: application of the endoconduit technique

J. vasc. bras; 13 (4), 2014
Endovascular aneurysm repair (EVAR) is already considered the first choice treatment for abdominal aortic aneurysms (AAA). Several different strategies have been used to address limitations to arterial access caused by unfavorable iliac artery anatomy. The aim of this report is to illustrate the advantag...

Impact of continuing education in vascular images analysis for endovascular planning

J. vasc. bras; 13 (4), 2014
Introduction: Manipulation of images using three-dimensional multiplanar reconstruction algorithms (3D MPR) and maximum intensity projection (MIP) is dependent on prior understanding of the method's true validity and its superiority over traditional semi-digital or analog methods of measurement. Objectiv...
