Background and purposeSuccessful revascularization can often improve functional outcome after large intracranial arterial occlusions. However, incomplete or unsuccessful recanalization is often the end result after attempted mechanical thrombectomy. A study was undertaken to determine whether partial recanalization of proximal isolated middle cerebral artery (MCA) occlusions facilitates endogenous thrombolysis and spontaneous ...

Purpose: To present a case of aortic sac occlusion using an Amplatzer vascular plug II (AVP). Case report: A patient with sigmoid malignancy and an infrarenal aortic aneurysm ultimately required an axillobifemoral graft for acute limb ischemia. The sac was ligated at subsequent laparotomy. Persistent filling of the sac was ...

Although essential thrombocythemia (ET) may involve thrombotic complications, including arterial or venous thrombosis, there are no reports of major vascular complications, including both arterial and venous thrombosis, in a patient with ET. We report on a patient with a cerebral infarction affecting the right lateral thalamus and a stenotic lesion ...

The most efficient treatment for acute arterial embolism is operative embolectomy using Fogarty's balloon catheter, especially if a single large artery is involved. Unfortunately, although the early surgical success of arterial thromboembolectomy often seems acceptable, the early clinical outcome still remains unsatisfactory. This may be related to the incomplete restoration ...

Background: Total axilloaxillary cardiopulmonary bypass (CPB) is an alternative peripheral cannulation technique that has the advantages of antegrade flow during CPB, monohemispherical brain perfusion in case of circulatory arrest, and achieving excellent decompression of the heart during sternotomy. The results of this strategy, particularly beyond the immediately postoperative period, are ...

An 80-year-old woman with a 20-mm Medtronic Hall (tilting-disc) aortic prosthesis presented with episodes of chest pain associated with circulatory collapse and subsequent rapid spontaneous recovery. A computed tomography angiogram demonstrated no evidence of aortic dissection, pulmonary embolus, or coronary artery disease. A transthoracic echocardiogram demonstrated a well-functioning prosthetic aortic ...

Although most ischemic strokes are thromboembolic in origin and their management is endovascular or medical, some are haemodynamic in origin and their management may be surgical. We reviewed bypass indications, patient selection and surgical techniques used in our current practice. Extracranial-intracranial (EC-iC) bypass with superior temporal artery-to-middle cerebral artery (STA-MCA) ...

Brainstem auditory evoked potentials (BAEPs) have been used as a valuable neurophysiologic index of neuronal dysfunction in the level of the brainstem. BAEPs are also useful in subdividing evoked potentials into normal, slight, or pronounced in patients with vertebrobasilar insufficiency. We investigated the changes of BAEP after vertebrobasilar artery ischemia ...

Cerebral aneurysm is an irreversible dilatation causing intracranial haemorrhage with severe complications. It is assumed that the biomechanical factor plays a significant role in the development of cerebral aneurysm. However, reports on the correlations between the formation of intraluminal thrombus and the flow pattern, wall shear stress (WSS) distribution of ...

Intravascular treatment of cavernous dural arteriovenous fistula (dAVF) is usually safe and effective. However, we describe a patient with a rare brainstem hemorrhage during transvenous embolization (TVE). A 79-year-old woman suffered from left chemosis and diplopia. Cerebral angiography revealed a left cavernous dAVF with cortical venous drainage. The patient underwent ...

Background: Atherosclerosis is a systemic disease. Many ischemic stroke patients may have concomitant coronary artery disease (CAD). Detection and treatment of preclinical CAD in stroke patients may improve long-term outcome and survival because CAD is a major cause of death during follow-up in stroke patients. However, association between coronary and ...

Stroke in trisomy 21 may be due to cardioembolism, atherosclerosis, vasculitis, moyamoya disease, sinus venous thrombosis, internal carotid hypoplasia or infections like endocarditis with septic emboli, meningitis or brain abscess. In rare cases, however, stroke etiology remains unexplained. We present a 19 year old Caucasian girl with trisomy 21 with ...

Semilunar valve malformations are common human congenital heart defects. Bicuspid aortic valves occur in 2-3% of the population, and pulmonic valve stenosis constitutes 10% of all congenital heart disease in adults (Brickner et al., 2000) [1]. Semilunar valve defects cause valve regurgitation, stenosis, or calcification, leading to endocarditis or congestive ...

Endovascular techniques have shown to be useful in the management of vascular injuries because they transform a complex and potentially dangerous procedure into a safe one. We present the case of a 39-year-old man with congestive heart failure and abdominal bruit 11 years after an abdominal gunshot wound. Imaging studies ...

Although the association between elevated C-reactive protein (CRP) level and long-term outcome after ischemic stroke is well known, the association between CRP and early neurologic deterioration (END) has not yet been thoroughly studied. We investigated the impact of CRP on END in patients with acute ischemic stroke. From a prospectively ...

OBJECTIVES: The objective of this study was to compare the cerebral embolic load of filter-protected versus proximal balloon-protected carotid artery stenting (CAS). BACKGROUND: Randomized trials comparing filter-protected CAS with carotid endarterectomy revealed a higher periprocedural stroke rate after CAS. Proximal balloon occlusion may be more effective in preventing cerebral embolization ...

Introduction:There is little information regarding the comparative hemodynamic effects of adding milrinone or levosimendan to dopamine infusion in hypoxia-reoxygenated (H-R) newborns.Results:Severely hypoxic piglets had cardiogenic shock with depressed cardiac index (CI) and mean arterial pressure (MAP). The hemodynamics deteriorated gradually after initial recovery upon reoxygenation. Heart rate and CI improved ...

A 2-year-old boy was referred for evaluation of a systolic heart murmur. Two-dimensional Doppler echocardiogram showed an abnormal flow through the interventricular septum, directed upward and toward the posterior wall of the main pulmonary artery. Left coronary angiogram showed a normal distribution of the anterior descending and circumflex arteries. The ...

We describe a successful surgical treatment in a 2.5-year old boy with Loeys-Dietz syndrome, in whom we performed aortic arch and ascending aorta replacement with a valve-sparing operation (VSO) of the aortic root because of significant aortic insufficiency and dilation of the aortic root. We believe that VSO is ideal ...

Congenital tricuspid valve regurgitation (TR) is a relatively uncommon condition that includes a heterogeneous group of lesions with a unique management strategy. There are wide anatomic variations that lead to congenital TR in patients without Ebstein malformation. Possible etiologies may include primary valve abnormalities (eg, congenital absence of chordae) or ...

The constellation of Takayasu's disease most commonly includes aortitis with resultant coarctations and aneurysm formation. Surgical repair of these lesions can be compromised by the chronic inflammation of Takayasu's arteritis. We present a case of a 22-year-old female with Takayasu's disease who had undergone an ascending and aortic hemiarch replacement ...

A 31-year-old male presenting with intracranial hemorrhage manifesting as deep coma and anisocoria underwent immediate emergency surgery. Three-dimensional computed tomography (CT) angiography revealed stenosis of the right middle cerebral artery (MCA) and perfusion CT immediately after the surgery suggested severe hypoperfusion in the right MCA territory. Postoperative angiography demonstrated right ...
