OBJECTIVE: This study aims to evaluate dynamic morphological changes of intracranial aneurysms to predict intraoperative aneurysm rupture (IAR) during clipping. METHODS: Included in this study were 153 patients, who had ruptured and microsurgical-clipped aneurysms. All patients underwent dual-source computed tomography examination of electrocardiography-gated dynamic 4-dimensional computed tomography angiography before clipping. Original scanning data were reconstructed to produce 20 data sets of cardiac cycles with 5% time intervals...

Regional procedures for postthoracotomy pain control have classically focused on paravertebral blocks and thoracic epidurals; however, these techniques may be challenging in an increasingly obese population and contraindicated with numerous anticoagulant and antiplatelet agents. While less studied, truncal blocks allow analgesic intervention for this growing patient cohort. This case report describes placement of a deep serratus anterior plane catheter in an intubated, morbidly obese patient with a lumbar drain who failed extubation secondary to acute postthoracotomy pain...

OBJECTIVE In various disease processes, including unclippable aneurysms, a bypass to the upper posterior circulation (UPC) including the superior cerebellar artery (SCA) and posterior cerebral artery (PCA) may be needed. Various revascularization options exist, but the role of intracranial (IC) donors has not been scrutinized. The objective of this study was to evaluate the anatomical feasibility of utilizing the anterior temporal artery (ATA) for revascularization of the UPC. METHODS ATA-SCA and ATA-PCA bypasses were performed on 14 cadaver specimens...

Abdominal aortic aneurysm (AAA) is a prevalent and potentially life threatening disease. Many animal models have been developed to simulate the natural history of the disease or test preclinical endovascular devices and surgical procedures. The aim of this review is to describe different methods of AAA induction in animal models and report on the effectiveness of the methods described in inducing an analogue of a human AAA. The PubMed database was searched for publications with titles containing the following terms "animal" or ''animal model(s)'' and keywords "research", ''aneurysm(s)'', "aorta", ''pancreatic elastase'', "Angiotensin", "AngII" "Calcium Chloride" or "CaCl(2)"...

BACKGROUND: Coarctation of the aorta (CoA) with aortic arch hypoplasia (AAH) is a relatively common congenital heart disease in clinical practice. Nonetheless, the corrective surgical technique for infants and children is a clinical problem that remains controversial. In this study, we sought to evaluate the surgical effects of aortic arch (AA) reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch for infants and young children with CoA and AAH...

BACKGROUND: Previous studies have examined an association between the siesta habit and hypertension, as well as coronary heart disease. However, the relationship between a siesta and the risk of rupture of an intracranial aneurysm (IA) has not yet been established. We aimed to investigate the effects of a siesta on the risk of rupture of IAs. METHODS: We prospectively enrolled consecutive patients diagnosed with IAs at our hospital between January 2016 and December 2016...

The middle cerebral artery (MCA) usually bifurcates into a superior or frontal and inferior or temporal branch. However, it may have various branching pattern, and there may be additional arteries from the anterior circulation supplying its territory. The majority of them remain asymptomatic. Some cases may have aneurismal dilatation due to turbulent blood flow or the weak arterial wall. The surgical approach in these cases may be challenging due to complex anatomical pattern of MCA. In this report, we have described a distinct pattern of left MCA with an aneurysm which was not clear in computed tomography angiogram and further confirmed on digital subtraction angiography...

Ascending thoracic aortic aneurysm (ATAA) is a multifactorial disease with a strong inflammatory component. Surgery is often required to prevent aortic rupture and dissection. We performed gene expression analysis (Illumina HumanHT-12 version 3 Expression BeadChip) for 32 samples from ATAA (26 without/6 with dissection), and 28 left internal thoracic arteries (controls) collected in Tampere Vascular study. We compared expression profiles and conducted pathway analysis using Ingenuity Pathway Analysis (IPA) to reveal differences between ATAA and a healthy artery wall...

OBJECTIVE: Recent evidence suggests an important role for angiotensin-converting enzyme 2 (ACE2) in limiting abdominal aortic aneurysm (AAA). This study examined the effect of ACE2 deficiency on AAA development and the efficacy of resveratrol to upregulate ACE2 in experimental AAA. APPROACH AND RESULTS: Ace2 deletion in apolipoprotein-deficient mice (ApoE(-/)(-)Ace2(-/y) ) resulted in increased aortic diameter and spontaneous aneurysm of the suprarenal aorta associated with increased expression of inflammation and proteolytic enzyme markers...

A keyhole craniotomy is a type of pterional craniotomy that involves a minimally invasive approach for the treatment of cerebral aneurysms. Currently, the mini-pterional keyhole craniotomy (MPKC) and supraorbital keyhole craniotomy (SOKC) procedures are frequently performed. We evaluated the feasibility and safety of SOKCs and MPKCs for the clipping of ruptured intracranial aneurysms in the anterior cerebral circulation as an alternative to the pterional approach in a consecutive series of 25 patients. The rate of intraoperative aneurysmal rupture was 8% (2/25), and all ruptures were safely controlled...

A 14-year-old male patient with a history of atypical Kawasaki disease at age 2 presents with triple vessel giant coronary aneurysms. Over the last several years, he began experiencing angina and dyspnea on exertion, which was a result of fully occluded right coronary and left circumflex arteries and 90% stenosis in the left anterior descending artery. He underwent off-pump coronary artery bypass using the left and right internal mammary arteries. At 18-month follow-up, there is no evidence of ischemia. Off-pump bypass is a feasible option for surgical management of the stenotic and occlusive complications of Kawasaki disease...

BACKGROUND: Guidelines on the management of aneurysmal subarachnoid hemorrhage (aSAH) recommend euvolemia, whereas hypervolemia may cause harm. We investigated whether high early fluid input is associated with delayed cerebral ischemia (DCI), and if fluid input can be safely decreased using transpulmonary thermodilution (TPT). METHODS: We retrospectively included aSAH patients treated at an academic intensive care unit (2007-2011; cohort 1) or managed with TPT (2011-2013; cohort 2)...

BACKGROUND: During the past decade, endovascular treatment has become the treatment of choice for all types of aortoiliac occlusive disease, including TASC C and D lesions. Patency rates, however, are still below those of open surgical techniques. One propagated technique to improve patency rates is the use of covered stents. This review assessed the available literature on covered stents for aortoiliac occlusive disease. METHODS: An extensive search was performed of the MEDLINE, Embase, and Cochrane databases...

We report a case of central sleep apnoea (CSA) due to a giant vertebrobasilar aneurysm with brainstem compression. A flow diverter stent was deployed with coil embolization of the right vertebral artery distal to the posterior inferior cerebellar artery (PICA) to occlude the aneurysm. The patient's symptoms improved following therapy.
