Balloon atrial septostomy or Rashkind is a technique described almost half a century ago to dilate a preexisting atrial communication in order to enhance atrial mixing and to decompress the left atrium in congenital heart disease. With the contribution of fetal echocardiography this technique can be pre-planed, but, still many ...

Carotid artery stenting (CAS) is less invasive and has a lower incidence of systemic complications such as myocardial infarction compared with carotid endarterectomy. However, CAS is known to have a high incidence of ischemic complications due to distal thromboembolism. Progress has been made in the development of various distal protection ...

Coronary artery to pulmonary artery communications (CAPAC) are an important source of pulmonary blood flow in approximately 10% of patients with pulmonary atresia and ventricular septal defect (PA-VSD). A diligent look for these abnormal communications is important to prevent perioperative complications and achieve a complete repair. We present two cases ...

Idiopathic renal arteriovenous fistulas (RAVFs) are uncommon, and a left-sided inferior vena cava (IVC) is also rare. We report a large idiopathic RAVF in a 36-year-old woman who had progressive congestive heart failure. An abdominal computed tomographic scan revealed an enlarged IVC on the left side and a 5.0- × ...

This report describes cerebral aneurysmal rupture with asymmetry of ipsilateral dural sinus hypoplasia using quantitative color-coded I-Flow cerebral venography to identify the venous pressure gradient. We suggest the pressure gradient may be a potential factor in cerebral aneurysmal rupture. We used I-Flow quantitative cerebral venography to measure the venous pressure ...

Although the inferior petro-occipital vein has been recently used for vascular access to the cavernous sinus, few detailed descriptions of its anatomy are in the literature. We aimed to investigate the morphology and relationships of this vessel. Twelve latex-injected cadaveric heads (24 sides) were dissected to identify the inferior petro-occipital ...

Cerebral aneurysms presenting only with visual field defect are rare and usually large. Unruptured anterior communicating artery aneurysms rarely present with visual dysfunction as their only symptom. They are frequently not amenable to endovascular intervention because they lack a defined neck and must be decompressed to relieve the mass effect ...

We studied the association between oxidized low-density lipoproteins (OxLDLs) and early atherosclerosis, assessed by carotid artery intima-media thickness (cIMT), as well as with other known atherosclerosis risk factors in a sample of the general middle- and old-age population of Burgos (Spain). Circulating OxLDL showed a significant and independent association with ...

BACKGROUND AND PURPOSE:Use of protective stents may not be effective in coil embolization of wide-neck aneurysms involving the posterior communicating artery. Successful implementation depends on the caliber of the vessel, its angle of origin, and the manner in which its orifice is incorporated into the aneurysm. Presented here are the ...

The aim of the current study was to analyse the extra- and intracerebral course of the recurrent artery of Heubner (RAH) to provide detailed information for neurosurgeons operating in this area. The material for this study was obtained from cadavers (ages 31-75 years) during routine autopsies. A total of 70 ...

Because infundibular widening most commonly appears at the origins of the posterior communicating artery and anterior choroidal artery from the internal carotid artery, its occurrence in association with the anterior communicating artery (ACoA) or the A1-A2 junction can be misinterpreted as an ACoA aneurysm on angiograms. The authors report on ...

OBJECTIVE: Recent studies have suggested an association between periodontitis and atherosclerosis; however, the relationship between periodontal status and arterial alterations should be clarified. The purpose of this study was to examine associations between periodontal status and carotid intima-media thickness (cIMT) and arterial stiffness using the cardio-ankle vascular index (CAVI) in ...

OBJECTIVE: Deep hypothermic circulatory arrest may be associated with increased neural injury. We investigated whether short periods of deep hypothermic circulatory arrest are associated with altered neurophysiologic recovery or greater risk of injury. METHODS: Eighteen term infants with transposition of the great arteries undergoing the arterial switch operation were enrolled. ...

We report a pregnant woman with symptomatic deep venous thrombosis of the lower extremity distributing in the left iliac, femoral, popliteal and calf veins. Systemic anticoagulation therapy failed; however, treatment was successful through a combination of various endovascular procedures, including catheter-directed thrombolysis. During the therapies, an optional inferior vena cava ...

Small fistulae between coronary arteries and the pulmonary artery are common, but abnormal vascular communications between the coronary arteries and other cardiac structures are rare. They were first described by Krause in 1865. We report two cases of fistulous connexions between the circumflex coronary artery and the coronary sinus.

Acute expansion of an intracranial aneurysm is an extremely rare event. In this report, we describe the unusual radiographic documentation of acute expansion of a posterior communicating artery (PCOM) aneurysm from 4 to 8 mm, resulting in complete oculomotor nerve palsy. A 40-year-old man was admitted to our institution with ...

In contrast to size, the association of morphological characteristics of intracranial aneurysms with rupture has not been established in a systematic manner. We present an analysis of the morphological variables that are associated with rupture in anterior communicating artery aneurysms to determine site-specific risk variables. One hundred and twenty-four anterior ...

True hemodynamic assessment of the posterior communicating artery (PComA) by preoperative angiography in terms of its perforators and configuration (adult vs. fetal vs. transitional) can be challenging in the surgical treatment of aneurysms involving the PComA, posterior cerebral artery, and basilar artery. Indocyanine green videoangiography (ICG-VA) is a widely accepted ...

BACKGROUND AND PURPOSE: Large artery intracranial occlusive disease (LAICOD) is a predominant cause of ischemic stroke in China. Carotid intima-media thickness (CIMT) and presence of carotid plaque are also related to subsequent ischemic stroke. However, the correlation between these and LAICOD is less clear. METHODS: This was a community-based cross-sectional ...

A 67-year-old woman presented with memory impairment and behavioral changes. Brain MRI indicated hepatic encephalopathy. Abdominal CT scans revealed an intrahepatic portosystemic venous shunt that consisted of two shunt tracts to the aneurysmal sac that communicated directly with the right hepatic vein. The large tract was successfully occluded by embolization ...

Coeliac trunk (CT) is a ventral branch of abdominal aorta (AA) supplying the foregut through its three main branches, left gastric (LGA), common hepatic (CHA) and splenic artery (Standring et al., 2009). Branching pattern of CT may vary from above mentioned classical three to four, five or six. Additional branches ...

Seroepidemiological studies have given rise to the hypothesis that microorganisms like Chlamydia pneumoniae (CP), Helicobacter pylori (HP), cytomegalovirus (CMV), HCV types 1 and 2, and bacteria involved in dental or other unspecified infection sites may initiate or maintain the atherosclerotic process in lower limb arteries. However, not much attention has ...

Pulmonary arteriovenous malformation (PAVM) is a rare anomalous direct communication between the pulmonary artery and vein with a considerable risk of serious complications such as cerebral thromboembolism or abscess and pulmonary hemorrhage. Although the past, surgical resection such as lobectomy was mostly used to treat PAVM, the recent development of ...

Hyperglycemia has been associated with an increased risk of cardiovascular morbidity and mortality. Although numerous studies have demonstrated that hyperglycemia is associated with the atherosis component of atherosclerosis, limited studies have addressed the independent role of hyperglycemia in the pathophysiology of sclerotic vascular disease. We hypothesized that hyperglycemia, as assessed ...
