The usefulness and limitation of digital subtraction angiography (DSA) in Takayasu arteritis were investigated in 32 patients. Intravenous DSA was particularly useful in the follow-up of patients with an established diagnosis of Takayasu arteritis. Pulmonary arterial involvement could also be demonstrated with intravenous DSA as obstructive arterial changes and lack of accumulation of contrast medium in the pulmonary parenchyma. Detailed information concerning the site and extent of vascular involvement and development of collateral vessels were obtained with intraarterial DSA. Thickening of the thoracic aortic wall, however, could not be recognized with either intravenous or intraarterial DSA. Conventional angiography of the descending thoracic aorta is still required as an initial examination, particularly when there is no aortic arch involvement. However, there is no doubt that DSA has the potential to become the diagnostic procedure of choice in Takayasu arteritis.

Object Ruptured arteriovenous malformations (AVMs) are a frequent cause of intracerebral hemorrhage (ICH). In some cases, compression from the associated hematoma in the acute setting can partially or completely occlude an AVM, making it invisible on conventional angiography techniques. The authors report on the successful use of cone-beam CT angiography (CBCT-A) to precisely identify the underlying angioarchitecture of ruptured AVMs that are not visible on conventional angiography. Methods Three patients presented with ICH for which they underwent examination with CBCT-A in addition to digital subtraction angiography and other imaging modalities, including MR angiography and CT angiography. All patients underwent surgical evacuation due to mass effect from the hematoma. Clinical history, imaging studies, and surgical records were reviewed. Hematoma volumes were calculated. Results In all 3 cases, CBCT-A demonstrated detailed anatomy of an AVM where no lesion or just a suggestion of a draining vein had been seen with other imaging modalities. Magnetic resonance imaging demonstrated enhancement in 1 patient; CT angiography demonstrated a draining vein in 1 patient; 2D digital subtraction angiography and 3D rotational angiography demonstrated a suggestion of a draining vein in 2 cases and no finding in the third. In the 2 patients in whom CBCT-A was performed prior to surgery, the demonstrated AVM was successfully resected without evidence of a residual lesion. In the third patient, CBCT-A allowed precise targeting of the AVM nidus using Gamma Knife radiosurgery. Conclusions Cone-beam CT angiography should be considered in the evaluation and subsequent treatment of ICH due to ruptured AVMs. In cases in which the associated hematoma compresses the AVM nidus, CBCT-A can have higher sensitivity and anatomical accuracy than traditional angiographic modalities, including digital subtraction angiography.

Object The purpose of this study was to evaluate the diagnostic accuracy of an optimized angiographic CT (ACT) program with intravenous contrast agent injection (ivACT) in the assessment of potential aneurysm remnants after neurosurgical clipping compared with conventional digital subtraction angiography (DSA). Methods The authors report on 14 patients with 19 surgically clipped cerebral aneurysms who were scheduled to undergo angiographic follow-up. For each patient, the authors performed ivACT with dual rotational acquisition and conventional angiography including a 3D rotational run. The ivACT and 3D DSA data were reconstructed with different imaging modes, including a newly implemented subtraction mode with motion correction. Thereafter, the data sets were merged by the dual-volume technique, and freely rotatable 3D images were obtained for further analysis. Observed aneurysm remnants were electronically measured and classified for each modality by 2 experienced neuroradiologists. Results Digital subtraction angiography and ivACT both provided high-quality images without motion artifacts. Artifact disturbances from the aneurysm clips led to a compromised, but still sufficient, image quality in 1 case. The ivACT assessed all aneurysm remnants as true-positive up to a minimal size of 2.6 × 2.4 mm in accordance with the DSA findings. There was a tendency for ivACT to overestimate the size of the aneurysm remnants. All cases without aneurysm remnants on DSA were scored correctly as true-negative by ivACT. Conclusions By using an optimized image acquisition protocol as well as enhanced postprocessing algorithms, the noninvasive ivACT seems to achieve results comparable to those of conventional angiography in the follow-up of clipped cerebral aneurysms. The authors have shown that ivACT can provide reliable diagnostic information about potential aneurysm remnants after neurosurgical clipping with high sensitivity and specificity, sufficient for clinical decision making, at least for aneurysms in the anterior circulation located distal to the internal carotid artery. These preliminary results may be a promising step to replace conventional angiography by a noninvasive imaging technique in selected cases after aneurysm clipping.

Intravenous Dsa

Conventional arteriography, intraarterial digital subtraction angiography (DSA), and intravenous DSA were used in the evaluation of the patency of the pedal arterial arcades in 15 patients with advanced peripheral arteriosclerotic disease. Intraarterial DSA was found to be superior to conventional arteriography. In 12 of 15 patients, excellent or good results were achieved by intraarterial DSA compared with 5 or 15 patients examined by conventional arteriography. All intravenous DSA studies performed in 6 patients were classified as poor.

Introdução: A Arterite de Takayasu (AT) é uma vasculite que acomete a aorta e seus principais ramos, principalmente as artérias carótidas e subclávias. A espondilite anquilosante (EA) por sua vez é uma doença inflamatória crônica, que acomete preferencialmente a coluna vertebral, evoluindo com rigidez e limitação funcional progressiva do esqueleto axial. A associação dessas duas doenças é rara e de difícil diagnóstico. Casuística: Relata-se o caso de uma paciente do sexo feminino, 49 anos, apresentando dor e rigidez da coluna vertebral, cefaleia, vertigem, ausência de pulsos em membros superiores e hipertensão arterial sistêmica. A Angio-TC de aorta revelou oclusão dos troncossupra-aórticos (TSA) e sinais de espondilopatia, caracterizados por sindesmófitos entre os corpos vertebrais e sinais de anquilose da articulação sacroilíaca. A angiografia por subtração digital confirmou a oclusão completa dos TSA em suas origens e extensa circulação colateral. Foi iniciado tratamento com imunosupressores e corticoide, além de tratamento da hipertensão arterial sistêmica, observando-se redução dos níveis pressóricos e melhora da cefaleia, porém com manutenção da dor lombar e do enrijecimento articular. Conclusão: A ocorrência concomitante de duas doenças aparentemente distintas como a AT e a EA deve ser interpretada como a manifestação de um estado inflamatório sistêmico de etiologia ainda não totalmente definida. Palavras-chave: Arterite de Takayasu, Espondilite Anquilosante, Aorta Torácica, Angiografia Digital, Aortografia, Tomografia Computadorizada por Raios X.ABSTRACTIntroduction: Takayasu Arteritis (TA) is a large-vessel vasculitis that affects the aorta and its main branches, especially the carotid and subclavian arteries. Ankylosing Spondylitis (AS) in turn is a chronic inflammatory disease, that mainly affects the spine, evolving with stiffness and progressive functional limitation of the axial skeleton. The association of these two diseases is rare and difficult to diagnose. Case Report: We report the case of a female patient, 49 years, with pain and stiffness of the spine, headache, dizziness, absence of pulses in the upper limbs and systemic hypertension. The CT angiography revealed occlusion of the aorta of the supra-aortic trunks (SAT) and signals of spondylopathy, characterized by syndesmophytes between vertebral bodies and signs of ankylosis of the sacroiliac joint. The digital subtraction angiography confirmed a complete occlusion of the TSA in its origins and extensive collateral circulation. Treatment was started with immunosuppressants and corticosteroids, and treatment of hypertension, with a reduction in blood pressure and improvement of headache, although a maintenance of low back pain and joint stiffness was observed. Conclusion: The simultaneous occurrence of two seemingly distinct diseases such as TA and AS should be interpreted as the manifestation of a systemic inflammatory condition of unknown etiology not yet fully defined.Keywords: Takayasu Arteritis, Ankylosing Spondylitis, Thoracic Aorta, Digital Subtraction Angiography, Aortography, X-Ray Computed Tomography.
