Background Pipeline embolization devices (PEDs) are used for endovascular treatment of cerebral aneurysms but can be associated with delayed ipsilateral intraparenchymal hemorrhage (DIPH). Changes in intracranial hemodynamics after PED are poorly understood. Objective Here, we assess hemodynamic changes after PED in patients and compare these changes in patients with and without DIPH (DIPH+ and DIPH-). Methods Records of patients with distal internal carotid artery (ICA) aneurysms treated with PED at our institution between 2012 and 2017 were retrospectively reviewed...

Acute rerupture after coil embolization is defined as rerupture within three days after treatment; its prognosis is worse than that of rebleeding at other time periods. However, to date, little is known about complications during the acute phase. Therefore, we used the PubMed database to perform a review of acute rerupture after coil embolization of ruptured intracranial saccular aneurysms and increase our understanding. After reviewing the complications, we found that the cause of acute rerupture is unclear, but the following risk factors are involved: incomplete occlusion of the initial aneurysm, the presence of a hematoma adjacent to a ruptured aneurysm, an aneurysmal outpouching, poor Hunt-Hess grade at the time of treatment, and the location of the aneurysm in an anterior communicating artery...

We present a case of hemothorax due to ruptured mycotic aneurysm in three intercostal arteries in a 40-year-old male with methicillin-resistant Staphylococcus aureus infective endocarditis (IE) due to intravenous drug use. Microcoil embolization and thoracotomy successfully achieved hemostasis. Mycotic aneurysm is a rare complication of IE and is usually found in the intracranial vessels. Ruptured mycotic aneurysm in the intercostal arteries can be associated with IE and can present as acute hemothorax.

Neurofibromatosis type I (NF-1) induced vasculopathy is rare but catastrophic complication after aneurysmal rupture. We present the case of a 55-year-old female who developed hypovolemic shock because of left internal mammary artery (IMA) pseudoaneurysm rupture associated with NF-1. Even she was not detected NF-1 at the time of arrival in emergency room. We decided to perform percutaneous embolization instead of surgical approach. In this case, after intervention, the ruptured left IMA aneurysm was well treated...

Internal carotid artery (ICA) blister aneurysms are rare and challenging to successfully treat, using contemporary surgical or endovascular approaches, without partial or complete compromise of the parent vessel. We describe the use of a resheathable flow diverter, the Pipeline Flex Embolization Device (PFED) to perform stent-assisted coiling of a ruptured supraclinoid ICA blister aneurysm in a 56-year-old female who presented with a high-grade subarachnoid hemorrhage (SAH). The first PFED was deployed across the aneurysm neck to jail a microcatheter within the aneurysm dome, and then, two small coils were delivered into the aneurysm...

Multiple imaging modalities are available to evaluate aneurysms post-flow diverter (FD) placement. Though digital subtraction angiography (DSA) is the gold standard imaging modality post-FD placement, it is not perfect, and neither are other techniques, including contrast-enhanced magnetic resonance angiography (CE-MRA) and magnetic resonance imaging (MRI). We present a case of a 73-year-old woman with a right internal carotid artery (ICA) aneurysm treated with a pipeline embolization device (PED). Initial follow-up post-PED placement by three-dimensional time-of-flight (3D-TOF) MRA demonstrated aneurysm occlusion, which was confirmed by computed tomography angiography (CTA) and CE-MRA in subsequent follow-up appointments...

Stereotactic radiosurgery is a well-known treatment tool for arteriovenous malformations (AVMs). The method has high validity and minimal invasiveness, but late-onset problems involving tumor formation and vasculopathy induced by radiation have been reported. We present a rare case of a radiation-induced ruptured de novo aneurysm following Gamma Knife surgery (GKS) for an AVM. A 17-year-old, right-handed male underwent GKS for AVM at the left parietal lobe. After 3 years, a follow-up angiogram showed a residual AVM at the angular gyrus...

OBJECTIVE: We describe our experience of single-incision laparoscopic splenectomy (SILS) for an unruptured aneurysm of the splenic artery. CLINICAL PRESENTATION AND INTERVENTION: A 73-year-old woman was diagnosed as having a splenic aneurysm which enlarged from 14 mm to 22 mm in diameter within two years. Due to contrast agent allergy, transcatheter arterial embolization could not be performed; therefore, SILS was performed with a 4 cm Z-shaped incision. The operative time and intraoperative blood loss were 132 min and 27 mL, respectively...

Left ventricular (LV) apical thrombus is a clinically important complication which can cause systemic embolization in patients with anterior acute myocardial infarction (AMI). Systolic dysfunction has been a risk factor for developing LV apical thrombus in AMI patients. However, the role of diastolic dysfunction in the development of LV apical thrombus in these patients is still unknown. We performed this study to evaluate whether diastolic dysfunction can influence the development of LV apical thrombus in anterior AMI patients...
