CT angiography of lower extremities from anatomy to traumatic and nontraumatic lesions: a pictorial review

AbstractAfter the introduction and the quick improvement of multidetector computed tomography technology, computed tomographic angiography (CTA) has become the imaging examination of choice for the first assessment of patients affected by lower extremities acute disorders. The widespread availability of CT equipment, the high temporal and spatial resolution with post-processing reformation possibilities represent the main advantages of this technique, which can reliably identify different findings related to arterial vessel pathology, such as occlusion, dissection, active bleeding, and pseudoaneurysm. Radiologists should know the anatomy, the acquisition protocols, and the CTA appearances of the different vascular lesions. The right interpretation of CTA findings is essential to establish the best treatment management of each patient.

This post was originally written in 2013. A middle-aged man with STEMI  came to our CCU.  It is just another case of STEMI and asked my fellow to lyse. But it was not the case . He, told me, Sir, the patient had a syncope following chest pain and he has injured his face and Jaw. He was actively bleeding. When I saw this face, it was indeed  frightening. What shall we do ? When a patient  with STEMI presents with bleeding facial Injury Rush for Immediate PCI (Which was  of course not possible in our place as it happened out of office hours! ) Take that ultimate risk and thrombolysis Give only hepa...

We report a case of fatal GI hemorrhage in a woman with a remote history of endovascular graft repair of an abdominal aortic aneurysm. Postmortem examination included computed tomography (PMCT) and CT angiography (PMCTA), which revealed air in the aorta, loss of the fat plane between the aorta and duodenum, and direct extravasation of contrast from the aorta into the duodenum. To our knowledge, this is the first published report of secondary AEF diagnosed by PMCT and confirmed with PMCTA. We propose a set of imaging criteria by which PMCTA can be used to supplant traditional anatomical dissection in the medicolegal investi...

CONCLUSIONS: In selected cases, without availability of appropriate VCDs, a single Angio-SealTM-VIP 8F served as a feasible option to achieve sufficient hemostasis of transfemoral access exceeding 8F without relevant bleeding complications. Very low BMI, tall body-height, and severe atherosclerosis were identified to predispose to access site complications. PMID: 32402666 [PubMed - as supplied by publisher]

CONCLUSIONS: The orbital malformation and enlargement of inferior orbital fissure probably resulted in an abnormal infraorbital artery. Selective artery embolization may be chosen as a preceding treatment before orbital reconstruction surgery. PMID: 32370622 [PubMed - as supplied by publisher]

AbstractIt is estimated that 5 –14% of patients presenting with hemoptysis will have life-threatening hemoptysis, with a reported mortality rate between 9 and 38%. This manuscript provides a comprehensive literature review on life-threatening hemoptysis, including the etiology and mechanisms, initial stabilization, and manageme nt of patients. There is no consensus on the optimal diagnostic approach to life-threatening hemoptysis, so we present a practical approach to utilizing chest radiography, computed tomography, and bronchoscopy, alone or in combination, to localize the bleeding site depending on patient stabili...

CONCLUSION: The absence of vasospasm in the first DSA performed in patients with SAH and negative tomographic angiography could be a useful criterion for establishing an optimal follow-up protocol in these patients, without exposing them to unnecessary risks and radiation.

We describe a 43-year-old woman presenting with an asymptomatic LRVT complicating NCS. She was referred to our hospital for investigation of dysfunctional uterine bleeding, and detailed examination revealed endometrial cancer. Computed tomography angiography (CTA) and Doppler ultrasonography revealed compression of the LRV between the aorta and the SMA, as well as an LRVT. CTA performed 4  months after the administration of an anticoagulant showed complete disappearance of the LRVT. We have also included a review of published reports describing LRVT complicating NCS and discussed the clinical features of such a presentation.

Authors: Stević M, Vlajković M, Veličković F, Stanojević G, Nestorović M, Petrović F Abstract A 69 year old patient was admitted to hospital with massive gastrointestinal hemorrhage. The clinical presentation of the patient, except for bleeding, was dominated by the presence of neurofibromatosis type 1 - Von Recklinghausen disease. The patient was referred to multislice computed tomography (CT) angiography, magnetic resonance imaging (MRI), esophagogastroduodenoscopy and colonoscopy, which were performed without successful detection of the bleeding site. The MRI examination showed the existence of a tumor lo...
