OBJECTIVE Pediatric patients (age < 18 years) harboring brain arteriovenous malformations (AVMs) are burdened with a considerably higher cumulative lifetime risk of hemorrhage than adults. Additionally, the pediatric population was excluded from recent prospective comparisons of intervention versus conservative management for unruptured AVMs. The aims of this multicenter, retrospective cohort study are to analyze the outcomes after stereotactic radiosurgery for unruptured and ruptured pediatric AVMs. METHODS We analyzed and pooled AVM radiosurgery data from 7 participating in the International Gamma Knife Research Foundation...

OBJECTIVE Brain arteriovenous malformations (AVMs) are the most common cause of spontaneous intracranial hemorrhage in pediatric patients (age < 18 years). Since the cumulative lifetime risk of AVM hemorrhage is considerable in children, an improved understanding of the risk factors influencing hemorrhagic presentation may aid in the management of pediatric AVMs. The aims of this first of a 2-part multicenter, retrospective cohort study are to evaluate the incidence and determine the predictors of hemorrhagic presentation in pediatric AVM patients...

OBJECTIVE Pediatric patients are at risk for the recurrence of brain arteriovenous malformation (AVM) after resection. While there is general consensus on the importance of follow-up after surgical removal of an AVM, there is a lack of consistency in the duration of that follow-up. The object of this systematic review was to examine the role of follow-up imaging in detecting AVM recurrence early and preventing AVM rupture. METHODS This systematic review was performed using articles obtained through a search of the literature contained in the MeSH database, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

OBJECTIVE Large consecutive series on the size and location of ruptured intracranial aneurysms (RIAs) are limited, and therefore it has been difficult to estimate population-wide effects of size-based treatment strategies of unruptured intracranial aneurysms. The authors' aim was to define the size and location of RIAs in patients diagnosed with subarachnoid hemorrhage due to aneurysm rupture in a high-volume academic center. METHODS Consecutive patients admitted to a large nonprofit academic hospital with saccular RIAs between 1995 and 2009 were identified, and the size, location, and multiplicity of RIAs were defined and reported by patient sex...

The nonoperative management of sylvian fissure dermoid/epidermoid cysts presents a risk that is difficult to quantify. With rupture, potentially fatal complications such as chemical meningitis, hydrocephalus, fever, seizure, or meningeal irritation may occur. In this paper, we present an asymptomatic case of such a cyst with imaging evidence of prior rupture, and we review the literature for the likelihood of future complications. We use for illustration a case of a 68-year-old woman with imaging features of a sylvian fissure epithelial inclusion cyst who refused surgical intervention and review the literature for further investigation...

REVIEW
Michelle Brault, Andrew Oberst
Necroptosis is a lytic form of programmed cell death that involves the swelling and rupture of dying cells. While several necroptosis-inducing stimuli have been defined, in most cells this pathway is kept in check by the action of the pro-apoptotic protease caspase-8 and the IAP ubiquitin ligases. How and when necroptosis is triggered under physiological conditions therefore remains a persistent question. Because necroptosis likely arose as a defensive mechanism against viral infection, exploration of this question requires a consideration of host-pathogen interactions, and how the sensing of infection could sensitize cells to necroptosis...

An 81-year-old man presented with ruptured thoracic aortic aneurysm under stable condition. He had been suffering from chronic obstructive pulmonary disease, chronic renal failure and rheumatoid arthritis. We performed hybrid thoracic endovascular aortic repair via right anterior mini-thoracotomy inserting a device through a conduit on the ascending aorta. The patient was discharged without aorta-related complications.

We report a rare case of cardiac failure for intrapericardial hematoma 11 years after coronary artery bypass grafting. A 59-year-old man was admitted to our hospital with cardiac tamponade. Echocardiography and computed tomography scan showed severe compression of the left ventricle(LV) by a large mass sized about 5×8 cm. Coronary angiography showed total occlusion at circumflex branch (Cx) #11. The mass was diagnosed with intrapericardial hematoma. We performed removal of hematoma in the pericardial cavity, and removed hematoma had 126 g...

We report a case of pseudoaneurysm formation after implantation of Medtronic Freestyle stentless bioprosthesis with a full root technique. A 65-year-old man previously underwent aortic root replacement with a Freestyle bioprosthesis. Ten years after the initial operation, pseudoaneurysm of the aortic root with a diameter of 6 cm was observed by computed tomography. At the reoperation, there was no sign of infective endocarditis, and the pseudoaneurysm was found to originate from the ruptured left and noncoronary sinuses...

AIMS: Patients with an acute Achilles tendon rupture (ATR) take a long time to heal, have a high incidence of deep vein thrombosis (DVT) and widely variable functional outcomes. This variation in outcome may be explained by a lack of knowledge of adverse factors, and a subsequent shortage of appropriate interventions. PATIENTS AND METHODS: A total of 111 patients (95 men, 16 women; mean age 40.3, standard deviation 8.4) with an acute total ATR were prospectively assessed...

Blunt abdominal trauma causing gallbladder rupture is exceptionally rare in children. This injury is rare due to the size and anatomical location of the gallbladder, and a rapid diagnosis is often difficult to achieve due to delayed presentation. We report a ruptured gallbladder in an 11-year-old male as a result of blunt abdominal trauma from an all-terrain vehicle accident. Possible gallbladder injury was indicated on computed tomography and patient was successfully managed with cholecystectomy.

We describe the case of a young man with repeated hospital presentations for a variety of symptoms related to excessive bodybuilding and associated behaviours. He presented to our department (radiology) with right arm pain and loss of function. Ultrasound showed complete triceps rupture, rare in young patients and multiple cystic areas within the muscles of the arm. MRI revealed these to be multiple proteinaceous lesions within the muscle bellies and the possibility of self-innoculation was raised by the reporting radiologist...

The continuing increase in the prevalence of diabetes mellitus in the general population is predicted to result in a higher incidence of cardiovascular disease. Although the mechanisms of diabetes mellitus-associated progression of atherosclerosis are not fully understood, at clinical and pathological levels, there is an appreciation of increased disease burden and higher levels of arterial calcification in these subjects. Plaques within the coronary arteries of patients with diabetes mellitus generally exhibit larger necrotic cores and significantly greater inflammation consisting mainly of macrophages and T lymphocytes relative to patients without diabetes mellitus...

Aneurysms of the inferior thyroid artery (ITA) are extremely rare and potentially determine severe sequelae. We report a case of true ITA aneurysm in a 45-year old Caucasian woman treated with endovascular embolization; postoperative course was uneventful and, at 6-month follow-up, the aneurysm is completely thrombized. A systematic review of the literature has been also performed to identify the epidemiologic and clinical characteristics and diagnostic and operative options of this disease. Size alone is not able to predict the fate of the aneurysm and an aggressive treatment seems to be justified because of the high risk of complications in case of rupture...

PURPOSE: To present the clinical outcome of endovascular sealing of abdominal aortic aneurysms (EVAS) with the Nellix endoprosthesis in patients with abdominal aortic aneurysms treated in our institution. METHODS: This was a retrospective, single centre, observational cohort study. A departmental database was interrogated in order to extract demographics, clinical information and outcome of all patients treated with EVAS between December 2013 and December 2015. Outcome measures included technical success (successful device deployment and absence of any endoleak at completion angiography), mortality, major complications, incidence of endoleaks, aneurysm rupture and reintervention...

After Thoracic Endovascular Aortic Repair (TEVAR) for chronic type B aortic dissection (cTBD) the patency of the false lumen is quite common and its presence is associated with the risk of developing complications and is a predictor of death by aortic rupture. We report a case of a patient treated in emergency for the rupture of the false lumen in cTBD. He had previous TEVAR with persisting distal dissection and retrograde reperfusion of the false lumen. We performed an original endovascular treatment with graft relining and false lumen occlusion with a home-made "candy plug" obtained with two commercially available stent grafts...

We report a case of a compassionate treatment of a ruptured thoraco-abdominal aortic aneurysm in a 92-year-old patient. Patient was admitted to our emergency department for acute onset of pain irradiating to the back. Computed tomographic angiography showed the presence of a thoraco-abdominal aortic aneurysm with a contained rupture at infrarenal level. Given of the presence of a relative healthy visceral aorta, we decided to treat the patient by Ovation(®) (Endologix, Irvine, CA - USA) implantation in an off-label fashion...

PURPOSE: Chronic traumatism of the common femoral artery due to intravenous injection in drug abusers, in association with local infections and arterial wall weakening caused by HIV, can lead to the development of pseudoaneurysms. Rupture of pseudoaneurysm is a dramatic event in such patients and its correction is difficult and controversial. Most of the cases reported describe open surgical elective options, that consist in ligation, repair or substitution of the damaged arterial segment, employing when possible biological grafts...

BACKGROUND AND AIMS: EUS-guided transluminal drainage (EUS-TD) and sequential direct endoscopic necrosectomy (DEN) for pancreatic fluid collections (PFCs) using a dedicated biflanged metal stent (BFMS) has been reported as a useful alternative to using plastic stents or a conventional metal stent. However, current dedicated BFMSs have limitations. Recently, a new BFMS with solidly constructed biflanges and various stent lengths matched to the PFC condition has been developed. Herein, we prospectively evaluated this new BFMS for the treatment of PFCs...

Neurosurgeons increasingly use decompressive craniectomy (DC) in neurocritical care. In this review, the authors summarize the topic of DC for the neurointensivist. Following a brief overview of the procedure, the major indications for the procedure are described. This includes a review of the literature regarding well-established indications, such as infarction and traumatic brain injury, as well as lesser known indications, including intracerebral hemorrhage, ruptured cerebrovascular malformations, sinus thrombosis, and infection...
