Spontaneous Symptomatic Common Carotid Artery Pseudoaneurysm: Case Report and Literature Review
2015
Spontaneous common carotid artery pseudoaneurysm (CCAP) is rare but potentially lethal disease. A 78-year-old man presented with pain in correspondence of right neck side and slight right eye ptosis. No previous surgery, trauma, or venous catheterizations in the neck region were reported. The computed tomographic angiography (CTA) showed a 4-cm saccular CCAP. The patient was managed emergently with surgical CCAP excision. At 6-month follow-up, the patient is neck pain-free with complete ptosis regression, and the CTA shows no pathologic findings. The literature review reported 7 cases of pseudoaneurysm of carotid district. All these cases were managed by surgical approach, and in 1 case, an…
Bilateral Hypoglossal Nerve Palsy in an Adult Patient With Repaired Tetralogy of Fallot
2018
Introduction Spontaneous cervical artery dissection (sCAD) is a major cause of ischemic stroke in young and middle-aged adults, but the occurrence of multiple sCADs could suggest the presence of an underlying arteriopathy. Bilateral hypoglossal nerve palsy caused by extracranial internal carotid artery dissections have been rarely described. We present the case of a 3-vessel sCAD in a patient with repaired tetralogy of Fallot (ToF). Case report A 50-year-old man was admitted to our stroke unit for a sudden onset of left cervical pain, mild left ptosis, dysarthria, and dysphagia. His medical history was remarkable for surgically repaired ToF. Neurological examination showed left Claude-Berna…
Prognostic value of dipyridamole stress cardiovascular magnetic resonance imaging in patients with known or suspected coronary artery disease.
2007
ObjectivesWe evaluated the prognostic value of dipyridamole stress cardiovascular magnetic resonance imaging (CMR) in patients with chest pain and known or suspected coronary artery disease.BackgroundStress perfusion CMR has been incorporated in daily practice. Data on its prognostic value are preliminary.MethodsDipyridamole stress CMR was performed in 420 patients with chest pain and known or suspected coronary artery disease. The extent (number of segments according to the 17-segment model) of abnormal wall motion at rest (AWM-rest), abnormal wall motion with dipyridamole (AWM-D), perfusion deficit (at stress first-pass perfusion imaging), and delayed enhancement (at late enhancement imag…
Chest pain due to late huge coronary pseudoaneurysm following stent implantation
2011
A 50-year-old man was referred to our hospital because of persistent atypical chest pain. His past medical history was remarkable for a non ST elevation myocardial infarction, treated five months previously with PCI on the right coronary artery. Two months later, for chest pain, he underwent coronary angiography that showed a right coronary artery with slight ectasia near the stent. Five months later for the persistence of atypical chest pain he came to our clinic. Chest CT showed a 31.5 mm hematoma of the right coronary artery. Coronary angiography revealed a giant aneurysm, proximal to the stent. In the light of rapid growth of aneurysm, the risk of rupture and symptoms, we decided to tre…
Coronary plaque assessment of Vasodilative capacity by CT angiography effectively estimates fractional flow reserve.
2021
Abstract Background To evaluate the feasibility of non-invasive fractional flow reserve (FFR) estimation using histologically-validated assessment of plaque morphology on coronary CTA (CCTA) as inputs to a predictive model further validated against invasive FFR. Methods Patients (n = 113, 59 ± 8.9 years, 77% male) with suspected coronary artery disease (CAD) who had undergone CCTA and invasive FFR between August 2013 and May 2018 were included. Commercially available software was used to extract quantitative plaque morphology inclusive of both vessel structure and composition. The extracted plaque morphology was then fed as inputs to an optimized artificial neural network to predict lesion-…
Influence of carotid tortuosity on internal carotid artery access time in the treatment of acute ischemic stroke
2017
Purpose Carotid artery anatomy is thought to influence internal carotid artery access time (ICA-AT) in patients requiring mechanical thrombectomy for acute ischemic stroke. This study investigates the association between ICA-AT and carotid anatomy. Material and methods Computed tomography angiography (CTA) data of 76 consecutive patients presenting with acute ischemic stroke requiring mechanical thrombectomy for middle cerebral artery or carotid T occlusion were evaluated. The supraaortic extracranial vasculature was analyzed regarding take-off angles and curvature of the affected side. Digital subtraction angiography data were primarily analyzed regarding ICA-AT and secondarily regarding r…
Initial Experience in the Treatment of Extensive Iliac Artery Aneurysms With the Nellix Aneurysm Sealing System.
2016
Purpose: To assess the feasibility and effectiveness of the Nellix prosthesis in the treatment of common iliac artery aneurysms. Methods: Between May 2013 and June 2015, 230 patients underwent implantation of the Nellix device at 2 institutions. Fifty of these patients (mean age 76 years; 35 men) were identified as having 60 common iliac artery aneurysms (CIAAs) with a median diameter of 4 cm (range 3.5–7). The majority of patients had aortoiliac aneurysms (5, 70%), 10 (20%) had isolated CIAAs, and 5 (10%) had iliac anastomotic aneurysms after aortoiliac bypass. In 20 patients, the iliac aneurysm was the indication for the intervention; in the other 30 patients, the endovascular iliac repa…
Detection of Myocardial Infarction by Cardiac Magnetic Resonance in Embolic Stroke Related to First Diagnosed Atrial Fibrillation
2021
Elevated troponin levels are found in a significant number of patients who are diagnosed with acute embolic stroke (AES) after first diagnosed atrial fibrillation (AF). These myocardial injuries, which are known as cardiocerebral infarction (CCI), are potentially caused by coronary embolism and correspond to simultaneous cardiac and cerebral embolisms. However, this severe condition remains poorly understood. In this prospective study, we aimed to investigate the prevalence and the cardiac magnetic resonance (CMR) characteristics of CCI.Consecutive patients with first diagnosed AF hospitalized for AES in a neurovascular intensive care unit from 2019 to 2020 were included. Troponin Ic kineti…
Cytomegalovirus infection with interleukin-6 response predicts cardiac mortality in patients with coronary artery disease.
2001
Background —Prospective data relating previous exposure to cytomegalovirus (CMV) to the risk of cardiac mortality are controversial. We investigated the effect of previous exposure to CMV infection on the risk of future cardiac disease–related death in relation to an underlying inflammatory response. Methods and Results —Coronary angiography was performed in 1134 subjects, and 989 patients with documented coronary artery disease were studied prospectively. CMV-IgG titers and interleukin (IL)-6 levels were measured before angiography. Increasing titers of CMV correlated with the elevation of IL-6 levels ( P <0.001) after adjustment for possible confounders. All patients were followed up …
Diabetes and Peripheral Arterial Occlusive Disease
2000
The purpose of this study was to compare contrast-enhanced three-dimensional MR angiography with conventional digital subtraction angiography (DSA) for identifying and evaluating arteries of the distal calf and foot in diabetic patients with severe arterial occlusive disease who will undergo distal bypass surgery.Twenty-four feet of 24 consecutive patients with diabetes and limb-threatening lower extremity ischemia were prospectively imaged using an ultrafast three-dimensional fast low-angle shot sequence on a 1.5-T MR scanner. All patients also underwent DSA of the diseased extremity within 5 days. Images were interpreted in a randomized manner by two observers in conference. Each lower ex…
