aortoenteric fistula is a rare but significant clinical entity associated with high morbidity and mortality if remain untreated. clinical presentation and imaging findings may be subtle and prompt diagnosis can be difficult. herein, we present a patient who initially presented with abdominal pain and computed tomography showed an aortic aneurysm compressing duodenum without any air bubbles. one...

conclusion metallic stent placement is a safe and effective procedure for salvage of native hemodialysis fistula after unsuccessful balloon angioplasty. results twenty-one stents were applied. the anatomical and clinical success rate was 100%. seventeen additional interventions were done for 11 (55%) patients due to stent thrombosis or stenosis during follow-up. our 1- and 2-year secondary pate...

central nervous system infection is a rare complication of endovascular procedures. we report a 21-year-old woman presented with headache, nausea, vomiting, and right-sided hemiparesis 4 months after endovascular embolization of cerebral arteriovenous malformation. investigations led to the diagnosis of multiple brain abscesses. this is the sixth case report of brain abscess following endovascu...

background a gunshot wound to the lower extremity with combined skeletal and vascular injuries can be difficult to manage. in clinical practice, it is not always possible to assemble a multispecialty team to work seamlessly to attain this goal, and the end result may be unnecessary prolonged ischemic time. a covered endovascular stent (evs) can be used initially to restore perfusion without nee...

hepatic artery aneurysms are rare but potentially life threatening. we describe a novel case of a successful endovascular coil embolization of a huge hepatic artery aneurysm. a 67-year-old woman presented with recent abdominal pain that had begun from 2 weeks before referring to our hospital. sonographic and computerized tomographic (ct) findings revealed a huge hepatic artery aneurysm with 95 ...

transcatheter aortic valve implantation (tavi) is a new therapeutic option for patients with severe aortic stenosis with unacceptable surgical risk for conventional aortic valve surgery. a bicuspid aortic valve (bav) is the most common congenital cardiac disorder (1% of the population) and currently is considered exclusion criteria for tavi, because it predicts an increased risk of adverse aort...

Background and Aim: Endovascular neurosurgery is widely accepted as a useful modality for the management of neurovascular disorders. This retrospective study aimed to evaluate the causes of diagnostic and therapeutic neuroendovascular procedures, as well as the prevalence, type, location and management of vascular pathologies observed in Firoozgar Hospital, Tehran City, Iran. Methods and Mater...

vascular complications by compromising the blood flow to the allograft can have significant and sometimes life-threating consequences for the patient. high level of suspicion and aggressive utilization of diagnostic modalities can lead to early diagnosis and salvage of the allograft.  this review will summarize the current trends in the management of vascular complications after liver transplan...

Various experimental models have been developed to test interventional neuroradiologic techniques. Most have been used to test various devices and embolic materials, and a small number of models have been designed for teaching or training purposes. Experimental models in endovascular techniques have seldom been used to stimulate disease processes in order to facilitate their understanding.
