Chondrosarcoma of the jugular foramen.

Chondrosarcoma, although uncommon, must be included in the differential diagnosis of skull base tumors. The potential for morbidity and mortality, similar to other lesions located at this anatomic site, is related to compromise of adjacent vital neurovascular structures. Optimal surgical management is controversial and reliant on adequate tumor exposure. A case of myxoid chondrosarcoma of the jugular foramen is presented with a review of the common presenting signs and symptoms along with the radiographic and histologic features of these lesions. The surgical approach to chondrosarcoma and other lesions at this location has undergone an evolution in technique in recent years. This report details the approach used by the authors, which allows for reconstruction of the skull base with subsequent normal anatomic contour and functional hearing. The technique employs hydroxylapatite for reconstruction, which has not been previously described in skull base applications.

[A case of left atrial myxoma with ventricular septal defect and patent foramen ovale].

A 51-year-old female was referred to our institute because of chest oppressive feeling. Echocardiography and magnetic resonance imaging revealed a left atrial tumor with ventricular septal defect. At operation patent foramen ovale was recognized. After excision of the tumor including intraatrial septum, which defect was repaired using a Teflon patch, and the ventricular septal defect was closed directly.

[Jugular foramen syndrome caused by herpes zoster].

Multiple cranial nerve palsies frequently occur in patients with cephalic zoster. Nevertheless, to our knowledge, involvement of the glossopharyngeal (IXth), vagus (Xth) and accessory (XIth) nerves has not yet been reported. We report a case of jugular foramen syndrome with palatolaryngeal herpetic eruption, aseptic meningitis and a high level of serum antibody to varicella-zoster virus.

[Echocardiographic diagnosis of a thrombus trapped in a patent foramen ovale. Apropos of a case].

The authors report the case of a patient presenting with pulmonary embolism in which transthoracic echocardiography showed the presence of an intracardiac thrombus trapped in a patent foramen ovale; this was confirmed at surgery. It is rare to see this type of thrombus (which usually gives rise to paradoxical embolism) by transthoracic echocardiography. Previously, this used to be a postmortem diagnosis but the condition is often suspected nowadays when deep venous thrombosis and/or pulmonary embolism, an unexplained systemic embolism and a right-to-left interatrial shunt, are associated. However, the diagnosis can only be confirmed by the visualisation of the thrombus crossing the interatrial septum.

Arterial gas bubbles after decompression in pigs with patent foramen ovale.

With patent foramen ovale (PFO), thought to be a risk factor for some forms of DCS, venous bubbles may pass through the patent opening to become arterial bubbles. We exposed 14 anesthetized, spontaneously breathing pigs to air at 5 bar (500 kPa, absolute pressure) for 30 min and then rapidly decompressed at 2 bar/min to 1 bar. We measured intravascular pressures, blood gases, and, with transesophageal echocardiology, bubbles in the pulmonary artery and ascending aorta. Autopsy showed that six of the pigs had a PFO. Arterial bubbles occurred more frequently in the PFO group (in six out of six) than in the non-PFO group (in two out of eight, P < 0.01). When arterial bubbles were detected, the venous bubble count and the pulmonary artery pressure tended to be lower in pigs with PFO than in pigs without a PFO. We conclude that a PFO increases the risk of arterial bubbles after decompression.

[Catheter closure in atrial septal defects and open foramen ovale using the Sideris buttoned device].

Percutaneous nonsurgical closure is an alternative to surgical repair of a significant atrial septal defect (ASD) or a patent foramen ovale (PFO) associated with systemic embolism without other cause. We report the results of the first 35 patients (19 ASDs, 16 PFOs) in whom transcatheter closure was attempted. Diagnosis and follow-up were based on transesophageal echocardiography in the majority of cases. In all patients the "Sideris buttoned device" was used. A total of 19 patients (13 women) were treated for symptomatic ASD of the secundum type. The mean defect size before the intervention was 17 mm by echocardiography and 24 mm measured by balloon in the catheterization laboratory (stretched diameter) with a reduction to 4 mm after treatment measured by echocardiography. A total of 16 patients (5 women) underwent transcatheter closure of a PFO; 14 patients had had cerebral embolic events and 2 peripheral. During follow-up of 104 patient months, only one patient had a recurrent embolic event. He had at that time no occluder protecting the PFO after early embolization and extraction of the device.

[Pulmonary embolism and thrombus trapped in a patent foramen ovale. Cure by heparin therapy].

The authors report the case of a 84-year old patient admitted to hospital for pulmonary embolism. The diagnosis was made by ventilation and perfusion pulmonary scintigraphy. Transthoracic echocardiography was performed routinely and showed a thrombus wedged across a patient foramen ovale, confirmed at transoesophageal echocardiography. Spiral thoracic computerised tomography showed thrombus in the two main pulmonary arteries and the inferior vena cava. Thrombolysis or thrombectomy under cardiopulmonary bypass, was thought to carry an excessive risk at that age and with the left-sided position of the thrombus. The alternative was therefore anticoagulation which led to dissolution of the thrombus without recurrence of pulmonary embolism or cerebrovascular accident.

[Treatment of Bell's palsy with cortisone preparations administered into the stylomastoid foramen].

The authors discuss some problems connected with the aetiology and pathogenesis of Bell's palsy. Attention is called to conservative treatment of the palsy with particular reference to administration of cortisone preparations injected into the stylomastoid foramen. Good results were obtained in 90% of 205 cases treated in this way. The method provides good results with small doses of the drug and can be used in outpatient practice.

Right ventricular nerve sheath tumour and patent foramen ovale presenting with transient ischemic attack.

A 66-year-old man presented with dyspnea and a transient ischemic attack. Echocardiography revealed a right ventricular mass and patent foramen ovale. During surgery the mass was found to be a malignant nerve sheath tumour. Several weeks later, the patient developed small bowel obstruction, and laparotomy disclosed multiple metastases involving the small and large bowel. The paper describes the clinical course and management of this patient and reviews the pertinent literature.

[Persistent foramen ovale and cerebral embolism].

Paradoxical embolism through persistent foramen ovale is one of the mechanisms of cardiogenic cerebral embolism. Transesophageal and transthoracic echocardiography and transcranial Doppler ultrasound (TCD) allow to assess the connection between ischaemic stroke, and to indicate specific treatment.

Carcinoid heart disease with severe hypoxia due to interatrial shunt through patent foramen ovale.

Carcinoid heart disease occurs in approximately half of patients who have carcinoid syndrome and is the leading cause of death among these patients. It is typically manifest as right-sided valvular lesions, usually tricuspid insufficiency and pulmonary valve stenosis. This case report describes the unusual presentation of a patient with carcinoid heart disease and a large right-to-left shunt through a patent foramen ovale.

[A case of lupus myocarditis and nephritis with transient foramen jugular syndrome].

A 46-year-old man was admitted to our clinic because of acute heart failure. Six years before admission he was pointed out cardiomegary and hematuria. One year later, he was diagnosed as having jugular foramen syndrome. On admission, he had a fever and dyspnea. Pansystolic blowing murmur was audible at the apex. The chest ratio on his chest X-ray was 52.5%. An electrocardiogram showed left ventricular hypertrophy. An echocardiogram showed marked dilatation and severe dysfunction of left ventricle. Radionuclide scanning with technetium 99 m pyrophosphate identified inflammatory change in the apex. Myocardial biopsy showed fibrotic degeneration and IgG deposits in myocardium. Blood examination showed anemia, lymphopenia. positive anti-nuclear antibody (1000 times, shaggy pattern), positive anti ds-DNA antibody and hypocomplementemia. Furthermore, proteinuria was pointed out. Renal biopsy showed focal segmental glomerulonephritis with active necrotizing lesion (type III nephritis). Lupus myocarditis and nephritis was diagnosed. After prednisolone (80 mg/day) was administered. left ventricular function and hypocomplementemia improved. The ACE inhibitor was also used for proteinuria. In spite of a little amount of blood transfusion, he showed hepatic hemosiderosis. We suspect that the cause of hemosiderosis was related chronic inflammation of active lupus. It was treated with Erythropoietin.

Role of foramen ovale electrodes in presurgical evaluation of intractable complex partial seizures.

BACKGROUND: The value of intracranial electrodes such as depth electrodes and subdural grids for intracranial electroencephalographic (EEG) recording in patients with intractable epilepsies has been well recognized. A new technique, foramen ovale electrode (FOE) implantation, was first introduced by Wieser in 1984 for the lateralization of bilateral mesiotemporal lobe (MTL) onset of seizures. METHODS: Since October 1993, a multipolar, three-contact FOE has been used in 12 intractable epileptic patients for presurgical evaluation. The reasons for FOE implantation included bilateral MTL onset of seizures recorded by extracranial EEGs in nine patients, and extracranial EEG abnormalities inconsistent with the results of magnetic resonance imaging (MRI), positron emission tomogram (PET) or Wada test in three patients. Under general anesthesia, the FOEs were implanted according to the technique introduced by Kirschner, using Barters landmarks. RESULTS: After long-term telemetry recording with FOE, seven patients revealed clear onset of seizures originating from one side of the MTL and underwent anterior temporal lobectomy (ATL). Two patients had seizures of bilateral MTL onset. However, they received ATL due to predominantly unilateral interictal epileptiform discharges (EDs) and/or MRI and PET abnormalities. Seven (78%) of the nine operated patients became seizure-free after ATL. Three patients were considered not operable because two had multifocal onset of seizures and one had seizures with independent bilateral MTL onset. No serious complication resulted from implantation of FOE in this series. CONCLUSIONS: The semi-invasive technique of FOE is reliable for lateralization of bilateral MTL onset of seizures which are often not clearly recorded by extracranial EEGs. This procedure is safe and can be an alternative to invasive implantation of depth electrodes and subdural grids.

Doppler color-flow imaging: screening of a patent foramen ovale in children scheduled for neurosurgery in the sitting position.

A patent foramen ovale (PFO) is the most common cause of paradoxical air embolism during neurosurgical procedures in the posterior fossa in the sitting position in both adults and children. To detect right-to-left shunting, we performed Doppler color-flow imaging preoperatively in 30 children scheduled for neurosurgical procedures in the sitting position. A PFO was diagnosed on the basis of color alterations indicating an immediate blood shunt through a PFO. Six of 30 children (20%) had a PFO; in 4 of these children the sitting position then was avoided, and 2 children were operated on in a special supine position with minimal elevation of the head. Venous air embolism occurred in 9 of 24 (37%) children operated on in the sitting position and in none of the 6 children operated on in a nonsitting position. We conclude that Doppler color-flow mapping could be a useful noninvasive technique to screen children scheduled for neurosurgery in the sitting position for the presence of a PFO.

Paradoxical embolism through a patent foramen ovale.

The high prevalence of clinically silent venous thrombosis and the presence of a patent foramen ovale in up to 35% of the general population suggests that paradoxical embolism (PDE) may be the cause of an ischaemic stroke or a peripheral thrombo-embolic occlusion more often than is presently considered. We report an ante-mortem diagnosed case of PDE and a review of the literature. Contrast echocardiography with provocative manoeuvres is suggested as the key investigation for diagnosis and anticoagulation is the mainstay of therapy.

[Paradoxical embolism and thrombosis trapped in the foramen ovale. Role of transesophageal echocardiography].

The authors report a case of paradoxical embolism presenting with syncope and a transient cerebrovascular accident. A large thrombus was observed entrapped in the foramen ovale during transthoracic echocardiography and confirmed at transoesophageal echocardiography. Despite the recent cerebrovascular event surgery was successfully performed. This clinical situation, and a review of the literature illustrate the diagnostic value of transoesophageal echocardiography, the finding of an intra-atrial thrombus being a possible surgical indication when the clinical context is favourable.
