Combined percutaneous pulmonary valvuloplasty and patent foramen ovale closure in an adult with recurrent transient ischemic attacks.

We report the case of a 60-year-old man with a history of recurrent transient ischemic attacks, effort syncope, cyanosis, erythrocytosis and a systolic murmur. Echocardiography and catheterization showed severe pulmonary stenosis and a patent foramen ovale with a right-to-left shunt. The patient was submitted to combined percutaneous pulmonary valvuloplasty and patent foramen ovale closure using the Amplatzer device.

[Bridges through the obturator foramen and suprapubic bridges].

Bridging through the obturator foramen and suprapubic cross-bridging are among the types of atypical bridging most frequently used in vascular reconstructive surgery. Suprapubic bridging, as with axillofemoral bridging, makes revascularization possible when there are contra-indications to a transperitoneal approach to the aortic bifurcation. Bridging through the obturator foramen makes it possible to avoid the edge of the scrapa, particularly when there is suppuration. These types of bridging, which are often the only way of avoiding amputation or of taking a grave risk, give results that are quite acceptable if not comparable to those obtained by the standard techniques.

[Subdiaphragmatico-mediastinal lipoma through the foramen of Bochdalek; report of a surgical case].

A 53-year-old man was admitted to our hospital for evaluation of chest abnormal shadow at the left cardiophrenic angle. Computed tomography (CT) scan revealed a homogeneous mass of fatty density on the left diaphragm. Magnetic resonance imaging (MRI) demonstrated a well-demarcated tumor mass with a fatty signal intensity and, in the sagittal view, the mass showed continuity into the retroperitoneal fatty tissue. Extirpation of the tumor was performed under thoracoscopic procedure. The tumor was adhesive closely to diaphragm and extended into the retroperitoneal space through the foramen of Bochdalek. Pathologically the tumor was diagnosed as a mature lipoma. This tumor was considered to originated from the retroperitoneal fatty tissue under the diaphragm and to herniate into the mediastinum through the foramen of Bochdalek.

[Choroid plexus carcinoma of the foramen Luschka: a case report].

Choroid plexus carcinoma(CPC) is a rare intracranial neoplasm that usually arises in the supra-tentorial region of infants. We report an adult case of CPC that arose in the foramen Luschka. A 61-year-old woman presented with a 10-year history of dysarthria. CT showed an iso- to slightly high density mass in the left foramen Luschka. The tumor appeared as a low- to iso-intensity area in T1-weighted MR images, and as an iso- to high-intensity area in T2-weighted images. The tumor showed homogeneous enhancement with the administration of contrast medium. Imaging findings were non-specific and the differential diagnosis was difficult.

[Foramen ovale electrodes in the study of temporal lobe epilepsy].

Corticograms of the mesial structures of the temporal lobe may be obtained with the recently developed foramen ovale electrodes. Since their installation is easy and of low risk, they will probably displace other invasive techniques routinely used up to the moment for the localization and lateralization of epileptic foci originated in the temporal lobe. For the first time in our country, we have used this technique in 7 patients with medically intractable complex partial epilepsy. In all the patients, the study allowed to clear doubts about the laterality of the start of ictal activity and to define irritative foci not found with conventional continuous superficial electroencephalographic recordings. The procedure was uneventful and the implanted electrodes were optimally tolerated. Foramen ovale electrodes are an effective diagnostic method for temporal lobe epilepsies and their features are specially appropriate for our milieu.

The arcuate foramen. Variability in distribution related to race and sex.

The occurrence, varieties, and distribution by race and sex of the arcuate foramina observed in 1,000 consecutively seen cervical spine radiographs are reported. The complete foramen is significantly more common in males, without any racial predilection. The partial foramen is commonest in white females. The rate of occurrence seems independent of age.

Descriptive and topographic anatomy of the accessory infraorbital foramen. Clinical implications in maxillary surgery.

AIM: Study of frequency and position of accessory infraorbital foramen in a large craniological sample. METHODS: A sample of 1 064 skulls from the craniological collection of the Department of Anatomy, Pharmacology and Forensic Medicine of the University of Turin (Italy) was investigated. RESULTS: Accessory infraorbital foramen was found in 4.7% of the skulls (5.4% in male and 4.26% in female skulls) with a higher frequency on the left side, both in male and in female skulls. CONCLUSION: These results increase our knowledge of the interindividual anatomic variability of the infraorbital region and can be of help for the maxillo-facial surgeon, especially in trunk block of the infraorbital nerve.

The jugular foramen -- a morphometric study.

The jugular foramen (JF) varies in shape and size from side to side in the same cranium, and in different crania, racial groups and sexes. Side dominance is also said to be common. The foramen's irregular shape, its formation by two bones and the numerous nerves and venous channels that pass through it further compound its anatomy. A morphometric study of 20 (40 JF) adult male Nigerian dry skulls was carried out. A bony bridge completely partitioned the JF in 3 (7.5%) of the JF. There was no tripartite JF. The JF mean length on the right and left were 13.90 mm (11.6-17.0 mm) and 14.11 mm (9.2-20.2 mm), while their widths measured 10.22 mm (6.8 -14.4 mm) and 9.57 mm (7.4-12.8 mm) on the right and left respectively. The mean JF area on the right was 437.49 mm (265.35-669.54 mm) and that on the left was 419.48 mm (276.46-634.60 mm). Side predominance of one of the JF appeared in 80% of cases. When present, the predominance of the right side was 55%, with 25% on the left. There was a difference in the length and width on each side but no significant difference in the length, width and area of the JF between the two sides. There was a positive correlation between skull width/ length and height/length ratio and JF area and length on each side. In conclusion, complete bony subdivision of the JF was not common among our study population and although the JF was generally larger on the right in our population, this is not statistically significant. A higher skull width/length and height/length ratio is associated with a greater JF length and area.

Patent foramen ovale after lobectomy. A contraindication to completion pneumonectomy?

Patency of the foramen ovale (FO) is a very rare complication after lobectomy. Completion pneumonectomy after FO reopening has never been described before. In the reported case, a patent FO was diagnosed in a 52-year old man 9 months after a left upper sleeve lobectomy for a squamous cell carcinoma pT2N1. At the same time, bronchoscopy showed an endobronchial recurrence in the left main bronchus. The foramen was closed percutaneously by a 35 mm Amplatzer prosthesis. Dyspnea improved dramatically in the following 4 weeks and no more oxygen therapy was required. After complete restaging, a completion pneumonectomy was performed without any postoperative complication. This case report suggests that pneumonectomy in such delicate patients is feasible.

Patent foramen ovale in scuba divers. A report of two cases and a brief review of the literature.

Scuba diving (diving with a self-contained underwater breathing apparatus) has become a popular sport. Decompression illness may be due to the formation of gas bubbles in various body tissues at an increased ambient pressure. The gas can pass from the systemic venous circulation into the arterial circulation as a result of either pulmonary barotrauma or intravascular shunting. Gas emboli may be the cause of an increased prevalence of brain lesions in sport divers. The management of scuba divers (professionals and amateurs) with a patent foramen ovale is not clear. We present the cases of 2 subjects with decompression illness and a patent foramen ovale and briefly review the literature on this combination.

[Apical foramen position on mesio buccal root of the maxillary first molar. Study in Senegalese population].

The maxillary first molar is submitted to frequent endodontic treatment and more over, it presents the highest failure rates, often in relation with his mesio-buccal root. Several studies about failures factors showed implication of root canal anatomy often in relation with the frequency of second canal. However, other failures factors, as the foramen situation, which is very important in endodontic practice, could increase the failure rate. The aim of this study was to determine the foramen situation in Senegalese people. The results showed 63.85% of excentric foramina (83 out of 130). 86% of excentric foramina were located at 1.5mm radiology apex.

[Patent foramen ovale and stroke].

About a quarter of the adult population is known to have a patent foramen ovale, rarely accompanied by the presence of an interatrial septal aneurysm. A patent foramen ovale is found in more than 40% of patients younger than 60 years who had a cryptogenic ischemic stroke. Clinical and echocardiographic parameters allow the identification of patients at high risk of recurrence after a first cryptogenic stroke even if treated with Aspirin. A multidisciplinary approach allow the selected patients to benefit of a correction of their cardiac anomaly with promising long term results.

Device closure of a patent foramen ovale in a patient with lipomatous hypertrophy of the atrial septum.

The presence of a patent foramen ovale has been recognized as a risk factor for embolic stroke, and transcatheter device closure of patent foramen ovales is increasingly performed to reduce future neurological events. The present report discusses a patient who continued to have residual shunting following percutanous closure because of improper seating of the device in the presence of a lipomatous atrial septum.

Surgical observation of the agenesis of the foramen of Magendie.

We report a young girl who presented with headache and back pain. Dynamic MRI revealed no cerebrospinal egress from the median aperture (Foramen of Magendie) of the fourth ventricle and syringomyelia. A posterior cranial fossa exploration was performed and agenesis of the median aperture was observed. Following surgical penetration of the posterior aspect of the fourth ventricle and at the most recent follow-up examination, this patient's syringomyelia had resolved, as had her symptoms. Agenesis of the foramen of Magendie may be a rare cause of inhibition of normal cerebrospinal egress from the fourth ventricle with resultant syringomyelia.

The occurrence, variations and diameter of the human condylar canal in relation to the jugular foramen.

In medical practice, especially in analysis of radiograms and computed tomography scans, it is very important to be familiar with the anatomy of the skull base, not only the normal and typical anatomical structures but also the variations and anomalies. One of the important venous foramina of the human skull is the condylar canal. This structure is described as the most stable and permanent venous emissary, with a prevalence of up to 100%. In our study, based on 100 human macerated skulls, this canal was encountered in 81% of cases. In several it was double. We have not encountered any information on this in the available literature. We found that the condylar canal in humans could be double and that the size of the external opening of this canal is not crucial in relation to the size of the jugular foramen. There was no significant correlation between the jugular foramen and the condylar canal in our specimens.

Severe pneumonia with pneumatoceles and patent foramen ovale in an infant: optimal ventilation strategy?

We discuss a case of severe pneumonia with pneumatoceles in a 2-month old infant. Despite peak and plateau airway pressures kept below 30 and 25 cmH(2)O, respectively, the infant developed bilateral pneumothorax and pneumomediastinum caused by pneumatocele rupture, necessitating bilateral intercostal drainage. Application of positive end-expiratory pressure (PEEP) of 10 cmH(2)O at FIO(2) of 0.7 worsened oxygenation, and transthoracic echocardiography showed right-to-left shunting of blood through the patent foramen ovale. Therefore, PEEP had to be tapered to 6 cmH(2)O, and ventilation carried out at FIO(2) of 1 until the lung condition improved. The open lung strategy of higher increments of PEEP and lower FIO(2) for lung protective ventilation actually proved deleterious to our patient. We conclude that a subset of patients with acute respiratory distress syndrome with refractory hypoxaemia may have right-to-left shunting of blood through a patent foramen ovale. This can be detected by echocardiography, and these patients may benefit from a ventilation strategy aimed at lowering pulmonary vascular resistance.

[Patent foramen ovale, stroke, and echocardiography: diagnostic methodology and appropriateness of indications].

A patent foramen ovale is a frequent remnant of embryological development with clinical importance in stroke, decompression sickness, and migraine headache. The proposed mechanisms of stroke include paradoxical embolization, in situ thrombosis within the canal of the foramen, associated atrial arrhythmias. Cardiac right-to-left shunts can be identified by echocardiography and by transcranial Doppler ultrasound with the use of contrast agents and a Valsalva maneuver as provocation procedure. Relative value of different diagnostic tests, appropriate timing of the Valsalva maneuver, use of a diagnostic time window, and threshold in contrast agent microbubbles detection are thoroughly discussed. The value of echocardiography or of other diagnostic tests does not elucidate the effect of test results on patient management. The appropriate use of imaging requires an understanding of both the capabilities of the imaging technique and the value of therapy used to treat the identified condition. New information that does not improve outcome has no value. In patients with a cryptogenic stroke and an atrial septal abnormality the evidence is insufficient to determine whether warfarin or aspirin is superior in preventing recurrent stroke or death, but minor bleeding is more frequent with warfarin. There is insufficient evidence to evaluate the efficacy of surgical or endovascular closure.

[Thrombophilia and patent foramen ovale in young stroke patients].

INTRODUCTION: Patent foramen ovale (PFO) is a vascular risk factor in young stroke patients. OBJECTIVE: [corrected] We sought to analyze the prevalence of thrombophilia in young stroke patients with patent foramen ovale (PFO). METHODS: Prospective study; a total of 130 consecutive young stroke patients (female: 58.5 %; mean age: 34; range: 15-45 years) consecutively admitted to the hospital during 2002-2003. All patients underwent a diagnostic protocol including echocardiogram, carotid echodoppler, transcranial doppler with bubble test, brain tomography scan or magnetic resonance imaging. Thrombophilia studies included fasting plasma levels of protein C, protein S, antithrombin III, lupus anticoagulant, anticardiolipin antibodies, lupus anticoagulant, antinuclear antibodies, and genetic testing for the factor V Leiden and C677T methylene tetrahydrofolate reductase mutations. Stroke subtype classification was done according to TOAST criteria. RESULTS: Etiology of stroke was: cryptogenic (67 %), cardioembolism (14.6 %), large artery atherosclerosis (8.5 %), small vessel occlusion (3.8 %) and other causes (5.4 %). 42 patients (32.3 %) had a PFO; 41 % of cryptogenic stroke patients had a PFO while 14.3 % of known cause stroke patients had a positive PFO (p = 0.003; OR: 4.15; IC 95%: 1.47-12.29). 23.8 % of positive PFO patients (10/42) had migraine, while 9.1 % negative PFO patients suffered migraine (OR: 3.13; CI 95 %: 1.02- 9.69; p=0.023). Prevalence of thrombophilia in positive and negative PFO patients, in young with cryptogenic stroke and stroke patients with known etiology, and in cryptogenic stroke patients with and without PFO was similar. CONCLUSIONS: Thrombophilia does not seem to be an additional factor to the excess of risk observed in young patients with cryptogenic stroke and PFO.
