The utility of transarterial embolization and computed tomography for life-threatening spontaneous retroperitoneal hemorrhage

AbstractPurposeTo assess the safety and efficacy of transarterial embolization (TAE) and to evaluate the utility of contrast-enhanced computed tomography (CE-CT) for life-threatening spontaneous retroperitoneal hemorrhage (SRH).MethodsNineteen patients underwent TAE following CE-CT for life-threatening SRH. CE-CT and angiographic findings, technical successes, and clinical successes were evaluated. The diagnostic performance of CE-CT for the detection of active bleeding arteries was also assessed by two independent readers.ResultsActive extravasation of contrast material was accurately observed in 78.9 ‒84.2% of the patients on CE-CT. Angiograms revealed active extravasation in 37 arteries of 15 patients (78.9%), and 4 patients showed no sign of active bleeding. Sensitivity, positive predictive value, and accuracy rate of CE-CT for the detection of active bleeding vessels was 59.5%, 62.9‒71.0% and 55.6‒60.0% respectively. The successful embolization of 48 intended arteries was achieved in all the patients, including empirical TAE in four patients. Hemodynamic stabilization was achieved in 17 patients (89.5%) with a significant decrease in transfusion (p

Conclusion: Neuro-endoscopic hematoma removal may be the optimal management method for hemorrhagic MMD in the acute stage in terms of the maximum preservation of pre-existing collateral anastomosis without affecting the potential donor vessels used for future revascularization surgery.

Aortoenteric fistula (AEF) is a rare cause of gastrointestinal (GI) bleeding. If not promptly diagnosed and treated the associated mortality is very high. The role of endovascular treatment is not yet defined. In this paper we report a clinical case of a 94-year-old male admitted in the emergency department with rectal bleeding. Due to detection of a pulsatile abdominal mass, a computed tomography angiography (CTA) scan was performed, which established the diagnosis of aorto-enteric fistula due to a left common iliac artery aneurysm (CIAA) ruptured to the sigmoid colon and also revealed an abdominal aortic aneurysm (AAA) a...

We report an unusual case of a late intercostal artery pseudoaneurysm, after a video-assisted thoracoscopic surgery, presenting as a large intra-parenchymal lung mass. Diagnosis was made by biphasic computed tomography angiography and contrast-enhanced pulsed-wave doppler ultrasound. To minimize the risk of aneurysm bleeding immediate angiographic embolization was planned and successfully performed.IAP should be considered in presence of lung mass in patients who have previously undergone an intervention with intercostal approach to prevent life-threatening complications.

ConclusionsIn both patients with giant cell arteritis, three-dimensional computed tomography angiography revealed improvement in stenosis and stoppage of temporal artery after glucocorticoid treatment. We conclude that computed tomography angiography along with magnetic resonance angiography, positron emission tomography-computed tomography, and ultrasonography are important for the diagnosis of giant cell arteritis.

CONCLUSION: Despite the high risk of aneurysmal rebleeding within a few hours after SAH, emergency cerebral angiography after SAH can be acceptable without increasing the risk of intra-angiographic rebleeding when using current angiographic techniques and equipment. PMID: 31484228 [PubMed]

This study introduces our new aortic root reinforcement technique and reports our early operative results and midterm follow-up results.A retrospective analysis study was performed on 235 patients (aged 53.2 ±15.5 years) who were admitted to our hospital for ATAAD surgery and underwent the procedure with our new technique between October 2011 and June 2016. Two vascular graft rings were placed inside and outside aortic root, followed by a running horizontal mattress suture, placed just above the coronary artery ostiums and aortic valve commissures, with another horizontal suture at distal end of the aortic root stum...

We report a case of efficient recanalization of large arterial occlusion after rapid injection of rt-PA. Patient concerns: A 78-year-old man was admitted with right-sided hemiplegia and global aphasia that occurred an hour ago. Diagnoses: His brain computed tomography (CT) revealed no hemorrhage, suggesting cerebral infarction. Interventions: Ten percent of a total rt-PA dose was injected over 1 minute promptly. The remainder of rt-PA was designed to be infused for 60 minutes. Unexpectedly, during the study of CT angiography, administration of rt-PA was completed within 5 minutes. CT angiography showed occlusion f...

CONCLUSION: The splenic artery has quite different variation types and knowledge of these variations are useful for the planning and conduct of surgical and radiological procedures of the upper abdomen, including laparoscopic operations. Our study is the first in the medical literature classifying variations in the origin and branching pattern of the splenic artery. PMID: 31436304 [PubMed - as supplied by publisher]
