Radiomics in the CT diagnosis of ovarian cystic malignancies - a pilot study.

Background And Aims: The conventional computed tomography (CT) appearance of ovarian cystic masses is often insufficient to adequately differentiate between benign and malignant entities. This study aims to investigate whether texture analysis of the fluid component can augment the CT diagnosis of ovarian cystic tumors.

Methods: Eighty-four patients with adnexal cystic lesions who underwent CT examinations were retrospectively included.

Textural Analysis of the Hyperdense Artery Sign in Patients with Acute Ischemic Stroke Predicts the Outcome of Thrombectomy.

Textural analysis is pivotal in augmenting the diagnosis and outcomes of endovascular procedures for stroke patients. Due to the detection of changes imperceptible to the human eye, this type of analysis can potentially aid in deciding the optimal type of endovascular treatment. We included 40 patients who suffered from acute ischemic stroke caused by large vessel occlusion, and calculated 130 different textural features based on the non-enhanced CT scan using an open-source software (3D Slicer).

Transarterial Embolization of Ruptured Pancreaticoduodenal Artery Pseudoaneurysm Related to Chronic Pancreatitis.

We presented a 67-year-old woman with lightheadedness, diaphoresis, and acute epigastric and right hypochondrium pain, with a past medical history including stage 2 essential hypertension, chronic ischemic cardiomyopathy, and class 1 obesity. An abdominal contrast-enhanced CT scan showed an extensive hematoma (3 × 4 cm in size) located intra-abdominally, adjacent to the duodenojejunal area, with hyperdensity around the duodenum, positioned inferior to the pancreas (30-59 HU). Moreover, the CT scan also revealed an enhancing lesion as a pseudoaneurysm of the inferior pancreaticoduodenal artery, measuring 5 × 8 × 8 mm with active bleeding and associated hematoma.

Computed Tomography Angiography Markers and Intraluminal Thrombus Morphology as Predictors of Abdominal Aortic Aneurysm Rupture.

Background: Abdominal aortic aneurysm (AAA) is a complex vascular disease characterized by progressive and irreversible local dilatation of the aortic wall. Currently, the indication for repair is linked to the transverse diameter of the abdominal aorta, using computed tomography angiography imagery, which is one of the most used markers for aneurysmal growth. This study aims to verify the predictive role of imaging markers and underlying risk factors in AAA rupture.

Endovascular treatment of an aneurysm associated with fenestration of the supraclinoid internal carotid artery: Case report and review of the literature.

Background: Fenestrations or divisions of the vascular lumen into separate channels appear to be common anatomical variations in patients with intracranial aneurysms. The most frequent sites of occurrence are the anterior communicating artery (ACom), followed by vertebrobasilar and middle cerebral artery (MCA) locations.

Case Presentation: A 61-year-old female was brought to the emergency department after experiencing severe headache with abrupt onset, nausea, and vomiting.

Postpartum Acute Basilar Artery Occlusion Secondary to Vertebral Artery Dissection. Case Report and Literature Review.

Female patients in the peripartum and postpartum periods have an increased risk of stroke than nonpregnant women. Cerebrovascular complications of pregnancy represent a significant cause of maternal mortality and morbidity and are potentially disabling. Acute basilar artery occlusion secondary to spontaneous vertebral artery dissection in the postpartum period is an infrequent entity and a major diagnostic and treatment challenge.

The Removal of a Fractured Guidewire During Mechanical Thrombectomy. a Case Report.

Recent randomized controlled trials have transformed the treatment of acute ischemic stroke. Mechanical or aspiration thrombectomy is the main treatment option for occlusions of large intracranial vessels. Despite its high technical success rate, endovascular thrombectomy can sometimes be complicated by anatomical peculiarities or device failures.

Diagnostic and prognostic computed tomography imaging markers in basilar artery occlusion (Review).

Acute ischemic stroke treatment has been revolutionized by the addition of mechanical and aspiration thrombectomy. Randomized controlled trials have proven beyond doubt, the substantial clinical impact of endovascular interventions in anterior circulation territory strokes. Unfortunately, patients with vertebrobasilar ischemic stroke could not be included in these early trials due to inherent clinical, radiological, and prognostic particularities of posterior circulation ischemia; thus, indications for the treatment of posterior fossa strokes and basilar artery occlusion (BAO) are mainly based on retrospective studies and registries.

Stroke secondary to giant-cell arteritis: A literature review.

Stroke is a leading cause of death and disability worldwide. In addition to the classical etiologies of stroke as atherosclerosis and cardioembolism there are many unusual, rare causes, which require a high level of clinical suspicion and further investigations for correct and early diagnosis and adequate treatment. Giant-cell arteritis or temporal arteritis, the most frequent vasculitis in the elderly population is one of the uncommon causes of stroke.

Rivaroxaban for the treatment of cerebral venous thrombosis: a single-center experience.

The mainstay of cerebral venous thrombosis (CVT) treatment according to current guidelines is parenteral anticoagulation with unfractionated heparin or low-molecular-weight heparin followed by long-term oral anticoagulation with vitamin K antagonists. Direct oral anticoagulants (DOACs), including the factor Xa inhibitor rivaroxaban, are used occasionally off-label for CVT based on individual treatment plans. This publication sought to report our experience with rivaroxaban for the indication of CVT and to review the relevant literature data concerning this topic.

Fenestration of the cervical internal carotid artery misdiagnosed as dissection.

Internal carotid artery (ICA) anatomical variations are relatively rare occurrences during diagnostic imaging procedures. Their presence can have important prognostic consequences in the evaluation of vascular neurological diseases. It is therefore important to have a good knowledge about these variations, in order to avoid unwarranted medical interventions.

Bilateral vertebral artery occlusion without stroke secondary to giant cell arteritis.

Ultrasound examination has become an important tool in the diagnosis of giant cell arteritis, revealing the suggestive hypoechoic arterial wall thickening (halo sign). Vertebral artery involvement is not unusual in giant cell arteritis, but bilateral vertebral artery occlusion secondary to this affection is a rare condition and only a few cases have been reported so far. We report a case of an 84-year-old male patient with anterior ischaemic optic neuropathy secondary to giant cell arteritis, with bilateral occlusion of the vertebral arteries manifested with nonspecific neurological signs, detected during the ultrasound scan of the cervical arteries.
