Aim: To determine the value of three-dimensional (3D) digital subtraction angiography (DSA) in the detection of intracranial aneurysms and to compare 3D technique with DSA. Materials and Methods: A retrospective analysis of 50 patients with 60 intracranial aneurysms who underwent both conventional DSA and 3D-DSA for the evaluation of intracranial aneurysms was conducted. The presence of aneurysms, detection of aneurysmal neck, size, location, presence of additional and small aneurysms analyzed from the two protocols were compared.

OBJECTIVEAneurysm growth is considered predictive of future rupture of intracranial aneurysms. However, how accurately neuroradiologists can reliably detect incremental aneurysm growth using clinical MRI is still unknown. The purpose of this study was to assess the agreement rate of detecting aneurysm enlargement employing generally used MRI modalities.METHODSThree silicone flow phantom models, each with 8 aneurysms of various sizes at different sites, were used in this study. The aneurysm models were identical except for an incremental increase in the sizes of the 8 aneurysms, which ranged fr

Résumé :

The evolution of imaging techniques and their increased use in clinical practice have led to a higher detection rate of unruptured intracranial aneurysms. The diagnosis of an unruptured intracranial aneurysm is a source of significant stress to the patient because of the concerns for aneurysmal rupture, which is associated with substantial rates of morbidity and mortality. Therefore, it is important that decisions regarding optimum management are made based on the comparison of the risk of aneurysmal rupture with the risk associated with intervention.

Background: Time-of-flight (TOF) magnetic resonance angiography (MRA) is widely used to identify aneurysm in human brain. Various deep learning models have been developed to help TOF-MRA reading in the field. The performance of those TOF-MRA analysis tools, however, faces several limitations in cerebral aneurysm detection. These challenges primarily come from the fact that cerebral aneurysms occupy less than 0.1% of the total TOF-MRA voxel size.

Résumé :

Abstract BACKGROUND Cerebral aneurysm initiation and evolution have been linked to hemodynamic and morphological factors. Stenotic morphology upstream to a bifurcation can alter hemodynamic patterns and lead to destructive vessel wall remodeling and aneurysm initiation. The effect of more subtle proximal variations in vessel diameter on bifurcation aneurysm development has not been evaluated. OBJECTIVE To investigate whether vessel tapering is associated with aneurysmal presence at the middle cerebral artery (MCA) bifurcation. METHODS Bilateral catheter three-dimensional rotational angiographi

Résumé :

Abstract The detection of intracranial aneurysms is of a paramount effect in the prevention of cerebral subarachnoid hemorrhage. We propose in this paper, a new approach to detect cerebral aneurysm in digital subtraction angiography (DSA) images by fusing several sources of knowledge. After a brief description of a priori knowledge that the expert has provided about cerebral aneurysm, we propose a system architecture including fuzzy modeling and data fusion. The results on the studied cases are very promising.

Purpose: The value of CT angiography in the detection and evaluation of aneurysms was compared to digital subtraction angiography (DSA) Material and Methods: Seventeen patients with acute subarachnoid hemorrhage (SAH) or with known or suspected aneurysm were investigated by means of spiral CT angiography, which included 3D reconstruction. These findings were compared with those at DSA Results: In 16 patients, 20 aneurysms were found; the remaining patient had an ectatic vessel that simulated an aneurysm.

Résumé :

The mortality rate of patients with ruptured pancreaticoduodenal artery aneurysms is high; therefore, it is recommended to treat pancreaticoduodenal artery aneurysms regardless of their size. In small pancreaticoduodenal artery aneurysms, however, identification of the access route on two-dimensional arteriography is sometimes difficult because of the superimposition of many hypertrophied branches of pancreaticoduodenal arteries on the aneurysm. We report two cases of ruptured pancreaticoduodenal artery aneurysm embolized successfully with metallic coils, assisted by automated feeder-detection

Résumé :

The modern epidemiological picture of syphilis is such that the detection of syphilitic mesaortitis, as a manifestation of cardiovascular pathology in tertiary syphilis, represents only 10% of cases. One of the most frequent and serious complications of mesaortitis is an aortic aneurysm. The nonspecific nature of symptoms and clinical course of such aneurysms sometimes complicates the timely detection of this pathology, that leads to high mortality at the hospital stage. This article describes a rare case of syphilitic mesaortitis complicated by aortic aneurysm.

Today, abdominal aortic aneurysm surgery is a fairly well-studied area of medicine. Nevertheless, some questions remain rather debatable. No clear criteria for giant aneurysms have been developed so far. The available foreign and domestic literature reports about 40 cases of surgical treatment of giant abdominal aortic aneurysms, 16 of which are cases of aneurysm rupture. Open surgery remains the method of choice in the treatment of giant aneurysms due to the pronounced technical difficulties of endovascular intervention.

Abstract BACKGROUND: Indocyanine green videoangiography (ICGV) is becoming routine in intracranial aneurysm surgery to assess intraoperatively both sac obliteration and vessel patency after clipping. However, ICGV-derived data have been reported to be misleading at times. We recently noted that a simple intraoperative maneuver, the “squeezing maneuver,” allows the detection of deceptive ICGV data on aneurysm exclusion and allows potential clip repositioning. The squeezing maneuver is based on a gentle pinch of the dome of a clipped aneurysm when ICGV documents its apparent exclusion. OBJECTIVE
