[A right-to-left shunt through a patent foramen ovale without pulmonary hypertension].

We report the case of a man 67-years-old with right-to-left shunt through a patent foramen ovale in absence of pulmonary hypertension. The contrast and transesophageal echocardiography showed significant right-to-left shunt and provided insight about the mechanisms that cause it. The aortic root was enlarged compressing the right atrium. Surgical repair was performed, the foramen ovale was closed and right atrial enlargement with a patch was carried out. Disappearance of the shunt was confirmed by means of transesophageal echocardiography in surgical-room.

[Transvenous catheter occlusion of the patent foramen ovale in paradoxical embolism].

Paradoxical emboli are assumed to be one cause for cerebral strokes of unknown etiology. These emboli usually cross from the right to the left heart via a patent foramen ovale. We describe the transvenous catheter occlusion as an alternative to surgical closure. There were no complications. The echocardiographic follow-up of 12 and 14 months demonstrated complete closure of the foramen ovale without recurrence of neurologic symptoms.

[Differential diagnosis of neurinomas of the jugular foramen and glomus jugulare: a clinical case].

Neurinomas or schwannomas of the jugular foramen are rare tumors whose differentiation from tumors of the jugular body may be difficult because they share common symptoms. Since schwannomas at this site are less aggressive than tumors of the jugular body and certain elements of their treatment differ, it is important to make a correct diagnosis promptly. A well-documented case of schwannoma of the jugular foramen is reported and its differential diagnosis is discussed in the light of the literature.

Heart transplantation complicated by a patent foramen ovale of the recipient atrial septum.

A patent foramen ovale after heart transplantation is a relatively uncommon occurrence. We report a case of a 58-year-old man with profound hypoxemia after orthotopic cardiac transplantation for end-stage ischemic cardiomyopathy. Transesophageal echocardiography demonstrated the presence of a patent foramen ovale in the recipient atrial cuff. Primary closure was performed with correction of the right-to-left shunt.

Percutaneous biopsy of cavernous sinus tumors through the foramen ovale.

OBJECTIVE: We present a new application to the widely used Hartel percutaneous route through the foramen ovale to the parasellar region to obtain aspiration biopsies of lesions arising from or invading the posterolateral part of the cavernous sinus. METHODS: Thirteen patients with cavernous sinus lesions that were diagnosed using imaging underwent aspiration biopsy by this route. Nine of them were subsequently operated on, and two will undergo surgery in the near future. For the remaining two, surgical removal of the tumor was not indicated. One of these two patients had a meningioma without any related symptoms and no growth revealed by repeated computed tomographic scans, and the other was diagnosed as having a nasopharyngeal carcinoma and consequently received radiotherapy. RESULTS: The accuracy of diagnosis with this technique was 84%. There was no complication related to the procedure. Having knowledge of the pathological diagnosis before determining the correct treatment helped to define the most appropriate strategy. CONCLUSION: We suggest that aspiration biopsy procedures through the foramen ovale be performed in cavernous sinus tumors before making any decision to indicate open surgical, radiosurgical, and/or radiotherapeutic treatments.

[A case of jugular foramen neurinoma originating from glossopharyngeal nerve].

A 39-year-old man was admitted with right hearing loss, tinnitus and vertigo. Neurological examination on admission revealed right facial palsy, right acoustic nerve disturbance and cerebellar ataxia. CT scan demonstrated a mass with intra-and extracranial extension in the pyramid bone concomitant with enlarged jugular foramen. MRI showed a ring-like enhanced, extra-axial mass in the right CP angle. Cerebral angiography showed no tumor stain. Venous phase of VAG revealed lateral displacement of the right sigmoidal sinus and obstruction of the internal jugular vein. Three dimensional CT was very useful to reveal enlarged jugular foramen. The tumor was resected totally and was approached through a right suboccipital craniectomy and mastoidectomy on July, 1994. Surgery confirmed that the tumor was a neurinoma originating from the glossopharyngeal nerve. After the operation, right facial palsy developed and transient fugitive CSF leakage was observed, but the patient is doing well. There was no amelioration of right hearing loss. JFN originating from the glossopharyngeal nerve is rare. Twenty-five cases of glossopharyngeal neurinoma are reviewed.

Spontaneous internal herniation through the foramen of Winslow: a case report.

A 41-year-old woman, who presented with acute onset of generalized peritonitis, was found to have a segment of strangulated small bowel incarcerated in the lesser peritoneal sac through the foramen of Winslow. The strangulated small bowel was reduced and resected. The predisposing factors for this condition as mentioned in the literature were not present in this case. In particular, the herniation was associated with a small foramen of Winslow and the presentation was one of rapidly developing peritonitis.

[Patent foramen ovale, aneurysm of the interatrial septum and cerebral ischemic complication].

Persistence of a patent foramen ovale (PFO) and the presence of an aneurysm of the interatrial septum (AIAS) are significantly more frequent in patients examined for cerebral ischaemic accident of unknown cause than in control subjects. The mechanism of ischaemic accidents associated with these cardiac abnormalities (frequently associated with each other), particularly the frequency of paradoxical embolism, remains unclear. In young patients, the risk of recurrent cerebral ischaemic accident appears to be generally low (1 to 2% per year). Secondary prevention remains empirical and controversial. No comparative studies are available to demonstrate the superiority of platelet antiaggregants, oral anticoagulants or invasive treatments, such as endovascular or surgical closure of the foramen ovale. A rational treatment can only be proposed on the basis of a better understanding of the natural history of ischaemic recurrences (identification of subgroups of patients at high or low risk of recurrence) and the therapeutic benefit risk ratio.

[Endovascular closure of a foramen ovale after a right pneumonectomy].

We report the case of a patient, 62-year-old, with a non small cell lung cancer treated by right pneumonectomy followed by chemo and radiotherapy. After surgery appeared a refractory hypoxemia increasing with supine position. Cardiac catheterism showed a right left shunt by reopening of the "foramen ovale". We have performed foramen's occlusion by endovascular method with prothetic material with good result until the death, 14 months later, by neoplasic evolution.

[The mental foramen syndrome].

The authors outline an extraordinary rare case of metastatic mandible carcinoma. The examined patient who earlier had a mastectomy due to breast carcinoma showed signs of the foramen mentale syndrome (numbness, pain, swelling) also on the right side after 5 years. The process of the generalized malignant tumour was first indicated by the mandibula metastatic tumour of the foramen mentale syndrome.

A neurofibroma affecting the first right cervical sympathetic ganglion and entering the jugular foramen of the skull base.

The case of a 27 year old male patient is presented. He had been complaining for three months prior to his initial medical examination of severe pulsating headache in the right occipital region, propagating toward the right parietal and temporal regions, occasionally extending along the neck to the right shoulder. The pain subsequently spread over the right tonsil, the voice became hoarse and the patient experienced difficulties in swallowing. On admission to our Department we found: persistent attacks of headache, dysphonia, dysphagia, the palatine arch was slow during phonation. The right pharyngeal reflex was absent, there was pain on palpation over the right occipital bone and the antero-lateral region of the neck, as well as hypotrophy of the right sternocleidomastoid muscle. Selective right carotid arteriogram was performed--the A/P view revealed lateral displacement of the right internal carotid artery 3 cm above the bifurcation, while on lateral view the artery was pushed forward. Computed tomography of the neck with bolus contrast enhancement showed a space-occupying lesion which caused asymmetry of right pharyngeal valleculae. During surgery the tumor was found to have a spindleform shape, to emerge from the jugular foramen and to involve within its capsule the first cervical sympathetic ganglion. After enlarging the jugular foramen we achieved total extirpation of the tumor along with the first right sympathetic ganglion. The histological characteristics of the specimen defined it as neurofibroma and neural ganglion. The headache subsided in the postoperative period, recovery of the voice without dysphonia was also noted. A month later the fibrillar contractions of the tongue disappeared.

Jugular foramen meningioma. Report of a case and review of the literature.

The occurrence of a meningioma within the jugular foramen is very rare. We present the case of a 33-year-old man who presented with five-year history of hoarseness and was found to have paralysis of lower four cranial nerves on the left. High resolution computed tomography showed a dumbbell shaped tumor of the left jugular foramen extending intracranially over the jugular tubercle and extracranially into the parapharyngeal space. The patient underwent staged neuro-otological surgery and the mass was removed subtotally with no recurrence in six years. Histopathologic diagnosis was transitional meningioma. Our review of the literature revealed 33 previously reported cases. Four of these cases had neurofibromatosis. All but one underwent some form of otolaryngologic surgery. Although twenty had an intracranial component to their tumor, only 11 had a craniotomy. The majority of the tumors were meningothelial meningiomas (60%). Only two cases were malignant meningiomas. We reviewed the clinical and radiological characteristics and summarized the benefits and pitfalls of existing surgical options.

[The micro-anatomy and clinical significance of the apical foramen in 1,282 permanent teeth].

To study the shape and size of the apical foramen of permanent teeth and their relations, we observed 1,282 permanent teeth. The teeth were photographed by XTL-2 photstero microscope. The rule of its shape and its clinical significance were discussed. In the 1,282 teeth, the round and oralshaped accounted for 94.77% (1,215/1,282), indicating that the morphological appearance of the apical foramen is inconsisted with that of vessels or/and nerves in the tissues.

Patent foramen ovale and pulmonary embolism. An underestimated co-morbidity following cardiac surgery.

When pulmonary embolism occurs in the presence of a patent foramen ovale the sudden increase in the right heart pressure can open the defect and could cause right to left atrial shunting. This may further aggravate the already existing hypoxemia, and the direct communication between the venous and the arterial circulation increases the risk of paradoxical embolization. In this paper we present a case of postoperative pulmonary embolization in a patient with patent foramen ovale, and the effects of these co-existing conditions are reviewed. In the cardiac surgical literature such a complication has not yet been described.

Paracondylar foramen--a new anomalous aperture of the occipital bone.

A new anomalous apperture has been identified by the author in association with the occipital bone. It was situated in the interval between the jugular fossa and the occipital condyles. Out of 118 skull bases examined four instances of this anomalous apperture were found (2 complete and 2 incomplete). The author speculates that they may transmitting the posterior condylar emissary vein in the absence of the condylar canal or in its abrrent course to the jugular foramen. In view of its topographical location the author proposes the name--'Paracondylar foramen' to this anomalous apperture.

Absence of correlation between infantile hypotonia and foramen magnum size in achondroplasia.

Virtually all infants with achondroplasia exhibit variably severe hypotonia in infancy. This hypotonia contributes to delays in motor development and risks for sudden death. Some have proposed that this hypotonia is a direct result of impaired function of long tracts of the spinal cord, secondary to the intrinsic narrowing of the foramen magnum, which also is present in variable severity in all children with achondroplasia. We postulated that if foraminal constriction causes infantile hypotonia, then there should be a strongly positive correlation between foraminal size and severity of hypotonia. Therefore, clinical and computed tomographic data in 71 infants were retrospectively reviewed. We found no correlation. These results suggest that there is no direct relationship and foraminal size does not affect severity of hypotonia. Other potential explanations for this infantile hypotonia are considered.

Angelman syndrome in a daughter with del(15) (q11q13) associated with brachycephaly, hearing loss, enlarged foramen magnum, and ataxia in the mother.

We report on a 4-year-old girl with Angelman syndrome who has an apparent de-novo del(15) (q11q13) originating from a maternally derived chromosome. Her mother had severe brachycephaly, sensorineural hearing loss, speech impediment, and mild ataxia. CT brain scans showed an enlarged foramen magnum in the mother and daughter but magnetic resonance imaging (MRI) showed no brainstem abnormality in either. This family demonstrates that some Angelman syndrome cases may be dominantly transmitted with variable expression and associated with abnormal or cytogenetically apparently normal chromosome 15.

Transcatheter patent foramen ovale closure for secondary prevention of paradoxical embolic events: acute results from the FORECAST registry.

Patients with patent foramen ovale (PFO) and paradoxical embolism are at increased risk for recurrent events. Percutaneous PFO closure is a new treatment modality aimed at secondary prevention. We report the multicenter experience of interventional closure of PFO using two different devices in 272 patients. The mean age was 51 +/- 14.2 years and 52.9% were males. The implantation procedure resulted in an initial complete shunt closure rate of 74.3% with a periprocedural complication rate of 6.6%. There were no deaths or pericardial tamponade. The mean procedure time was less than 44 min under either conscious sedation, local or general anesthesia. This is the largest report to date demonstrating the procedural safety, reliability, and feasibility of the transcatheter PFO closure technique with the STARFlex and CardioSEAL septal implants. Randomized clinical trials are currently in progress to identify patients most likely to benefit from this intervention.
