Successful percutaneous mechanical thrombectomy in a haemodynamically unstable patient with massive pulmonary embolism
Massive pulmonary embolism with haemodynamic instability has a high mortality. Traditionally these patients are treated with i.v. thrombolytic therapy. When this therapeutic approach is contraindicated, surgical embolectomy and most recently, percutaneous mechanical interventions are alternative treatment options. This case report presents a 73-year-old female with a residual hemiparesis secondary to a mengingioma resection 45 days previously, who presented with progressive shortness of breath, accompanied by oppressive chest pain, hypotension, tachycardia and severe hypoxaemia. CT pulmonary angiogram confirmed a massive pulmonary embolism extending into the lobar branches bilaterally. The patient was treated with percutaneous mechanical thrombectomy with excellent haemodynamic and clinica......

Patient selection for revascularization procedures in adult Moyamoya disease based on dynamic perfusion computerized tomography with acetazolamide challenge (PCTA)
Abstract The usefulness of dynamic perfusion computerized tomography for early diagnosis of stroke is well established. However, limited
data exists to assess the value of PCT in the evaluation of patients with chronic cerebral ischemia. The purpose of the study
was to assess the utility of perfusion computerized tomography with acetazolamide challenge (PCTA) in the evaluation of cerebral
perfusion and cerebrovascular reserve (CVR) in adult Moyamoya patients. From 2005–2008, 41 patients with Moyamoya were scrutinized
by PCTA. Of these, 22 patients (12 females, ten males, mean age 41 years) with ischemic symptoms from Moyamoya disease were
found to have no response or decreased cerebrovascular flow post-acetazolamide indicating compromised CVR. Eight had bilateral
sy......

Patient radiation doses in the most common interventional cardiology procedures in Croatia: first results
Apart from its benefits, the interventional cardiology (IC) is known to generate high radiation doses to patients and medical staff involved. The European Union Medical Exposures Directive 97/43/Euroatom strongly recommend patient dosimetry in interventional radiology, including IC. IC patient radiation doses in four representative IC rooms in Croatia were investigated. Setting reference levels for these procedures have difficulties due to the large difference in procedure complexity. Nevertheless, it is important that some guideline values are available as a benchmark to guide the operators during these potentially high-dose procedures. Local and national diagnostic reference levels (DRLs) were proposed as a guidance. A total of 138 diagnostic (coronary angiography, CA) and 151 therapeuti......

Fulminant Sepsis-Associated Encephalopathy in Two Children: Serial Neuroimaging Findings and Clinical Course
We report on two children with sepsis-associated encephalopathy. They presented with fulminant neurological damage on clinical, neuroimaging, and neurophysiological findings. At onset, both went into deep coma after status epilepticus, resulting in near brain death. Both patients showed diffuse brain edema on CT and severe brain dysfunction on electroencephalography within a day of onset. Brain magnetic resonance (MR) imaging of one patient on day 2 showed restricted diffusion in the basal ganglia and the subcortical white matter of the frontal and occipital lobes. Brain edema aggravated and lasted for a few months despite a variety of treatments. MR imaging in the chronic phase revealed cracking lesions extending to the cerebral white matter, the cerebellum, and the brainstem. MR angiogra......

Reply
We thank Dr. Abraham and colleagues for their interest in our paper (). They suggest that proximal claudication may be in part responsible for functional limitation in patients with peripheral artery disease. We most certainly agree and have shown data to that effect in our paper (). The measure of the runoff index from the magnetic resonance angiogram performed in each patient was an assessment of extent of peripheral atherosclerosis, corrected for the proximal nature of the disease (). The more proximal the atherosclerosis, the worse was the score on the runoff index. The runoff index correlated with all of the outcome measures performed, including treadmill time, time to claudication, 6-min walk, and oxygen consumption (see Table 3 in Anderson et al. []). The perfusion measures made usi......

Case report: Hip septic arthritis and abcess after diagnostic coronary angiography.
Authors: Ayhan H, Akar Bayram N, Keles T, Durmaz T, Bozkurt E
Coronary angiography is an invasive procedure which can have some complications. Septic arthritis and abscess after coronary angiography are extremely rare. In this case, a 49-year-old-man presented to our hospital with non-ST-segment elevation myocardial infarction. After coronary angiography, he had right leg weakness, femoral palsy, inguinal pain, but there was no bleeding or hematoma. The cause was right hip septic arthritis and abscess.

Periodic lateralized epileptiform discharges in neuropsychiatric lupus: association with cerebritis in magnetic resonance imaging and resolution after intravenous immunoglobulin.
Authors: Lim KS, Cheong KL, Tan CT
A 13-year-old girl with a known diagnosis of systemic lupus erythematosus presented with seizures and psychosis. An electroencephalogram (EEG) revealed continuous, non-evolving periodic lateralized epileptiform discharges (PLEDs) in the left temporal region, which did not resolve with benzodiazepine. A magnetic resonance imaging (MRI) brain scan demonstrated a focal hyperintensity in the left medial temporal and left occipital lobes, left thalamus and bilateral cerebellar white matter, with evidence of vasculitis in the magnetic resonance angiography. Intravenous immunoglobulin was given because of failed steroid therapy, which resulted in a full resolution of clinical, EEG and MRI abnormalities. Lupus cerebritis should be considered as a possible aet......

Validation of a new contrast material protocol adapted to body surface area for optimized low-dose CT coronary angiography with prospective ECG-triggering
Abstract In patients with large total blood volume contrast material (CM) dilution decreases coronary attenuation in CT coronary angiography
(CTCA). As increased blood volume is well paralleled by body surface area (BSA) we assessed a BSA-adapted CM protocol to compensate
for dilution effects. Low-dose CTCA with prospective ECG-triggering was performed in 80 patients with a BSA-adapted CM bolus
ranging 40–105 ml and injection rate ranging 3.5–5.0 ml/s for a BSA of <1.70 to ≥2.5 m2. Eighty control patients matched for BSA who had previously undergone routine CTCA with a fixed CM protocol of 80 ml at 5 ml/s
served as reference group. The average vessel attenuation from the proximal right (RCA) and the left main coronary artery
(LMA) was asses......

Effect of internal iliac artery ligation on ovarian blood supply and ovarian reserve.
Conclusions Internal iliac artery ligation in the treatment of obstetric hemorrhage leads to dilation of the ovarian arteries and reversed flow in the ovarian branches of the uterine arteries. These change the blood supply to the ovaries and impair ovarian reserve.

64-Slice Computed Tomography of Bovine Internal Mammary Artery Coronary Grafts [ORIGINAL ARTICLE]
In cases where conventional aortocoronary grafts cannot be used, No-React bovine internal mammary artery is a possible alternative. The aim of this study was to assess the patency and clinical performance of bovine internal mammary artery as a coronary bypass conduit, using 64-slice computed tomography coronary angiography. Eleven patients (mean age, 68.2 ±5.9 years) received 11 bovine grafts between 2002 and 2006. Eight of these patients were alive after a mean follow-up of 29.4 ±16.3 months. Their mean additive EuroSCORE was 6.5 ±3.2. The mean number of distal anastomoses was 2.5 ±0.5. Six grafts were anastomosed to the right coronary artery, 2 to the left anterior descending artery, and 3 to the circumflex artery. All 11 bovine grafts were found to be occlude......
