Time to conventional angiography in gastrointestinal bleeding: CT angiography compared to tagged RBC scan

AbstractPurposeTo compare CT angiography (CTA) and tagged red blood cell (RBC) scan as a function of time from these initial imaging studies to subsequent conventional angiography and catheter-directed embolization in patients with gastrointestinal (GI) bleeding.MethodsAn IRB-approved retrospective study was conducted of 35 consecutive patients diagnosed with GI bleeding that received angiography for planned catheter-directed embolization. Of these patients, 20 were diagnosed with bleeding using a tagged RBC scan, whereas 15 were diagnosed using CTA. The lengths of time between diagnostic study order to study completion, diagnostic study completion to angiography, and total time from diagnostic study order to angiography were calculated. The results of both groups were compared using at test withp value of

Rationale: The capsular warning syndrome (CWS) is a rare and special type of transient ischemic attacks (TIAs) syndrome. The pathophysiology of CWS is very complicate, and intracranial atherosclerotic stenosis (ICAS) is rare cause. Moreover, the effective and standard therapy has not yet been established. Patient concerns: A 47-year-old man experienced repeated and exacerbated TIAs of right hemiparesis and dysarthria. Fourteen hours after the first episode of TIAs, he developed more severe right hemiparesis and dysarthria, the National Institute of Health Stroke Scale (NIHSS) score was 12 points, and did not recover i...

Abstract Pulmonary embolism (PE) is a condition characterised by an obstruction of the pulmonary arterial system by one or more emboli. Advanced clinical practitioners are often faced with ruling out a diagnosis of PE in patients with non-specific symptoms such as dyspnoea and pleuritic chest pain, which can be fairly mild and therefore a diagnosis of PE easily missed. PEs can be a challenge to diagnose, especially in elderly people, since it can be difficult to differentiate their symptoms from other less serious illnesses. Widely used scoring tools are helpful to calculate a patient's probability of having a PE....

ConclusionTraumatic dACA aneurysm is a rare complication of brain trauma. Delayed intracranial haemorrhage and the sudden deterioration of neurologic function were the typical characteristics in patients with traumatic dACA aneurysm. CTA is the first-line screening modality for patients who present with intracerebral haemorrhage in the corpus callosum after trauma, particularly for patients who are older, in a poorer or critical condition. When the aneurysm is located in the A4 segment or involves a small branch, surgical trapping is the preferred definitive therapy to prevent further growth and disastrous bleeding. Early ...

ConclusionIn cases of OGIB, superselective mesenteric angiography (SSMA) with intraoperative methylene blue injection can be used as an adjunct to routine diagnostic modalities to guide surgical interventions for controlling hemorrhage and for limiting the extent of bowel resection.

A 40-something male presents to the stabilization room for evaluation following head on motor vehicle collision (MVC).  Pt was reported restrained driver, hit at city speeds,  with + airbag deployment.The MVC was unquestionably caused by the other car, not by this driver.The patient complained to EMS of chest pain and a prehospital EKG en route was concerning for STEMI.The patient was at all times hemodynamically stable, without evidence of any profuse bleeding.He had an ECG recorded on arrival to the ED:Anterior and Inferior STEMI with diffuse hyperacute T-waves. This ECG really can't be anything else. ...

The primary diagnostic procedure in patients with lower gastrointestinal bleeding (LGIB) should be colonoscopy, but colonoscopy may fail in the presence of massive hemorrhage without colon preparation. Therefore, technetium-99m (99mTc)-labeled red blood cell (RBC) scintigraphy or computed tomography (CT) angiography should usually be performed for identification of active bleeding prior to catheter angiography (CA), except in the presence of massive bleeding. Because most cases of LGIB are intermittent in nature, the rate of bleeding should be assessed immediately, prior to RBC scan, CT angiography, or CA, to increase the ...

ConclusionsMDCTA provides useful information for identifying the anatomical characteristics of bleeding-related BAs and nonbronchial systemic arteries for the management of patients with severe hemoptysis. However, MDCTA could not determine the individuals who need BAE through measuring diameter of BAs.
