Air embolism is a rare but potentially fatal complication of surgical procedures. Rapid recognition and intervention is critical for reducing morbidity and mortality. We retrospectively characterized our experience with air embolism during medical procedures at a tertiary medical center. Electronic medical records were searched for all cases of air embolism over a 25-year period; relevant medical and imaging records were reviewed. Sixty-seven air embolism cases were identified; the mean age was 59 years (range, 3-89 years)...

OBJECTIVE Vascular malformations of the spine represent rare clinical entities with profound neurological implications. Previously reported studies on management strategies for spinal dural arteriovenous fistulas (sDAVFs) appeared before the advent of modern liquid embolic agents. Authors of the present study review their institutional experience with endovascularly and surgically treated sDAVFs. METHODS The authors performed a retrospective, observational, single-center case series on sDAVFs treated with endovascular embolization, microsurgical occlusion, or both between 2004 and 2013...

A 55-year-old male with peripheral arterial disease underwent angioplasty of the right lower limb arteries via antegrade femoral access. Angio-Seal(®) closure device was used to treat the puncture site, whereby the intravascular sealing anchor accidentally embolized into the malleolar region of the right posterior tibial artery. Successful retrieval of the anchor was accomplished by a SpiderFX embolic protection device. This technique may be a useful approach to retrieve embolized foreign bodies via endovascular access...

We report the clinical details, imaging findings and management of a 45-year-old man who presented with recurrent transient ischemic attacks due to carotid free floating thrombus. Free floating thrombus of the carotid artery is a very rare condition with a high risk of distal embolic shower. The optimal treatment options are debatable and include medical management, surgical thrombectomy and endovascular thrombectomy. We describe the use of a stentriever with filter protection in the management of carotid free floating thrombus as a novel treatment option...

Inadvertent coverage of origin of internal iliac artery (IIA) during endovascular aneurysm repair may lead to type II endoleak. Except for open surgery, the endovascular solution is limited. We report a case with such complication that was successfully treated with coil embolization using retrograde extrastent approach. This is a new technique that has not been reported before, and as such, had been useful in the treatment of type II endoleak from IIA as an alternative to open ligation of IIA origin.

REVIEW
Clemens J Sommer
The vast majority of cerebral stroke cases are caused by transient or permanent occlusion of a cerebral blood vessel ("ischemic stroke") eventually leading to brain infarction. The final infarct size and the neurological outcome depend on a multitude of factors such as the duration and severity of ischemia, the existence of collateral systems and an adequate systemic blood pressure, etiology and localization of the infarct, but also on age, sex, comorbidities with the respective multimedication and genetic background...

INTRODUCTION: Traumatic intracranial aneurysms in children are rare and may occur as the result of closed or penetrating head trauma. Their natural history seems to be more aggressive. Most traumatic aneurysms have complex shape, tending to have a large neck or even a fusiform morphology. CASE REPORT: We present a case of a traumatic carotid artery aneurysm in a 9-year-old girl that was successfully treated with pipeline embolization device. DISCUSSION: Due to its dissecting nature, wall friability and lack of a substantial neck can make surgical clipping and selective coiling difficult and risky...

Totally implanted port devices are important for the administration of fluid and chemotherapeutic agents. However, their use may be associated with serious complications, such as catheter fracture and embolism. Most data on port catheter embolization consist of isolated case reports. We report a 6-year-old boy with relapse of an acute lymphoblastic leukemia. He presented with dysfunction of his totally implanted port device. Radiologic examination revealed a catheter fracture. Echocardiography showed the catheter embolized into the right ventricle...

Intravascular foreign bodies can cause serious complications and catheter fracture with or without embolization is a rare, serious event. Intravascular fragments from broken catheters can be retrieved percutaneously or surgically, and should be removed as soon as possible to prevent further lethal complications. A gooseneck loop snare is the most popular device for endovascular retrieval of intravascular foreign bodies. Herein, we present the first report of successful percutaneous retrieval of a fractured catheter using a balloon...
