Despite previous studies indicating a moderate/high incidence of angiography headache (AH), there is still limited data about the risk factors associated with its occurrence....
The present study aimed to assess the associations among demographic, clinical, and technical characteristics of cerebral digital subtraction angiography (DSA) and the occurrence of AH....
Cross-sectional analytical observational study with a sample comprised of individuals with a recommendation for elective DSA. Clinical interviews were conducted to assess the occurrence of AH, using a...
Among 114 subjects, the mean age was 52.8 (±13.8) years old, 75.4% (86/114) were women, 29.8% (34/114) had a history of migraines, and 10.5% (12/114) had chronic headaches. The overall frequency of AH...
3D angiography is strongly associated with the occurrence of AH, which has never been reported before. The association between a previous history of migraine and AH confirms the results of previous st...
Many large randomized trials in interventional cardiology have shown a significant advantage of transradial access (TRA) over transfemoral access (TFA). However, TRA has yet been widely used in Neurov...
A total of 380 patients underwent cerebral angiography in our center between January 2019 and January 2021. Among them, 192 patients underwent TRA, and 188 patients via TFA. The success rate of cerebr...
The operative success (94.27% vs 97.87%;...
TRA is effective and safe in cerebral angiography, and its use may be expanded....
Cerebral angiography through the transradial approach (TRA) is associated with a low risk of complications, but in rare cases, these complications can be life-threatening....
A 56-year-old female patient was admitted for transradial cerebral angiography due to the complaint of right limb weakness and the diagnosis of cerebral infarction and cerebral artery stenosis. During...
Mediastinal and thoracic hematoma may occur due to vessel perforation during TRA cerebral angiography, in which guidewire advancement must be cautious. Early detection and appropriate countermeasures ...
To evaluate the static and dynamic features of blood blister-like aneurysms (BBAs) using cerebral angiography to identify characteristic features to improve the diagnosis of these uncommon aneurysms....
Digital subtraction angiography (DSA) images were compared between patients with BBAs (n = 12, group A) and patients with unruptured paraclinoid aneurysms ≤ 5 mm in size treated by endovascular proced...
Compared to the group B, group A had a higher proportion of irregular vessel diameter (p = 0.013) and the delayed contrast medium outflow (p = 0.014). As well, stagnation of contrast medium along the ...
Irregular morphological features of the parent artery and delayed contrast medium outflow as characteristic findings of ruptured BBAs may improve the diagnosis of these uncommon aneurysms, which remai...
Trans-radial (TRA) access has become increasingly prevalent in neurointervention. Nonetheless, mediastinal hematoma after TRA is an infrequent yet grave complication associated with a notably elevated...
Carotid computed tomography angiography (CTA) showed calcified plaques with stenosis (Left: Severe, Right: Moderate) in the bilateral internal carotid arteries (ICAs) of an 81-year-old male presented ...
This case underscores the need for timely identification and precise manipulation of guidewires and guide-catheters through trans-radial access. The critical components of successful neuro-interventio...
The performance of a novel prototype four-dimensional (4D) digital subtraction angiography (DSA) for cerebral arteriovenous malformation (AVM) diagnosis was evaluated and compared with that of two-dim...
In this retrospective study, 37 consecutive cerebral AVM patients were included. The standard diagnostic results were concluded from the 2D and 3D DSA. Two 4D DSA volumes were reconstructed for each p...
Complete agreement was achieved between 4D DSA and 2D and 3D DSA in SM Grading Scale and intracranial aneurysm identification (agreement coefficient: 1) for both reviewers. The agreement coefficients ...
The performance of this prototype 4D DSA in cerebral AVMs diagnosis was largely equivalent to that of 2D and 3D DSA combination. Four-dimensional DSA can be regarded as a very good complement for 2D D...
To evaluate factors that influence the successful cannulation of intracranial vessels using a transradial approach....
A total of 61 transradial diagnostic angiograms were evaluated in a tertiary care center from July 2020 to December 2021. We evaluated the learning curve and aortic arch vessel factors that may influe...
Learning curve for the procedure was established after 21 cases. We were successful in cannulating the supra-aortic arteries except in 4 cases where we were unable to cannulate the left VA (vertebral ...
Transradial approach is a feasible and safe approach for performing cerebral angiography. Multiple factors can influence the procedure time and successful cannulation of intracranial vessels. With the...
The transradial approach (TRA) has become popular for diagnostic cerebral angiography. However, this approach is still used less often because of problematic formation of the Simmons catheter. The pur...
This retrospective study included consecutive patients eligible for right TRA cerebral angiography at our institution from 2021. To introduce the technique, the cerebral angiogram of formation of the ...
In total, 295 cerebral angiographies were evaluated. There were 155 (52.5 %), 83 (28.1 %), 39 (13.2 %), and 18 (6.1 %) patients with types I, II, and III aortic arches and bovine arch, respectively. T...
Pigtail catheter exchange may be an effective and safe technique for right TRA cerebral angiography. The findings of this report prompted institutions to apply this technique clinically and can serve ...
Cerebral angiography is the gold standard for diagnosing moyamoya disease (MMD), whereas magnetic resonance (MR) imaging/angiography is becoming more popular in the field of cerebrovascular disease du...
We analyzed 160 consecutive direct/indirect combined revascularization procedures for MMD preoperatively assessed using MR imaging/angiography alone. Perioperative complications were assessed for up t...
Sixty-four revascularization procedures were performed in 38 children, and 96 procedures were performed in 68 adults. There was no difference in the incidence of perioperative ischemic complications b...
Direct/indirect combined revascularization surgery based on our preoperative diagnostic protocol with the MR-first strategy resulted in favorable outcomes in pediatric MMD patients with relatively low...
Computed tomography (CT) angiography (CTA) is a non-invasive imaging method used to detect arteries and examine various brain diseases. When CTA is performed for follow-up or postoperative evaluation,...
