[Thoracoscopic pericardial fenestration for persistent pericardial effusion after radiotherapy for esophageal cancer; report of a case].

We performed thoracoscopic pericardial fenestration for persistent pericardial effusion after radiotherapy for esophageal cancer. An 85-year-old man who had radiation therapy (70.2 Gy) for esophageal cancer was admitted for shortness of breath. Chest computed tomography showed a pericardial effusion. During the 6 months prior to this admission, the patient had undergone percutaneous pericardial drainage 3 times for cardiac tamponade. We performed thoracoscopic partial pericardiectomy with creation of a pleuropericardial window via one access port. Histopathologically, no malignant cells were found in either the resected pericardium or the pericardial effusion. Therefore, we believe the persistent pericardial effusion was secondary to radiotherapy. There was no recurrence of the pericardial effusion for 7 months postoperatively. In summary, thoracoscopic pericardial fenestration is useful in both the diagnosis and treatment of persistent pericardial effusion.

[Transdiaphragmatic pericardial fenestration: laparoscopic modification of the procedure].

We present a modification of the laparoscopic pericardial fenestration, an already accepted method for the treatment of the pericardial effusion caused by intrathoracic malignancies. We used this new technique in 5 patients. Laparoscopy was performed with three ports standard technique and dissection with Ultrascision was used for the fenestration of the pericardium. The mean operation time was 26 minutes (8-49). No complications developed. The average length of hospital stay was 2.8 days (2-5).

Fenestration of the posterior communicating artery.

A 21-year-old male presented with sudden onset of right-sided third nerve paresis. Angiogram showed a fenestrated posterior communication artery on the right side and no other vascular anomalies. There was no other lesion that could suggest a cause for the third nerve weakness. Fenestration of the posterior communicating artery has not been reported till date. The case is discussed and the literature on the subject is reviewed.

[A case of acute A type aortic dissection with lower extremity ischemia--percutaneous fenestration of the aortic septum followed by ascending aortic graft replacement by open distal anastomosis and retrograde cerebral perfusion].

A 56-year-old woman with severe back pain and a cold, pulseless right extremity was admitted to our hospital. Angiogram revealed a type A aortic dissection extending from ascending aorta to the aortic bifurcation with no definite re-entry point. The false lumen gave origin to the right renal artery and the right external iliac artery was occluded. Therefore, a catheter was manipulated into the true lumen through a percutaneous right femoral artery approach, and was advanced into the false lumen through the right posterolateral wall of the dissecting aortic septum. Fenestration was then performed with fully dilated angioplasty balloon across the septum. Immediately after the procedure, the patient's symptoms improved. The day after the fenestration, replacement of the ascending aorta with 24 mm woven Dacron graft was followed under the deep hypothermia and the retrograde cerebral perfusion. The patient followed a satisfactory postoperative course and postoperative angiogram showed a complete closure of the entry at the ascending aorta and adequate revascularization of the right renal and external iliac arteries.

Transcatheter closure of secundum atrial septal defects and fenestrated Fontan using the Amplatzer septal occluder. Initial prospective study.

OBJECTIVE: To evaluate the safety and efficacy of transcatheter closure of secundum atrial septal defects and fenestrated Fontan with the Amplatzer septal occluder. METHODS: Fifteen consecutive patients, with a significant interatrial communications, were considered for the procedure; four patients with defects that were too large or with deficient margins were excluded after initial transesophageal echocardiography. RESULTS: Eleven procedures were performed in 11 patients (10 atrial septal defects and 1 fenestrated Fontan) aged 9 to 38 years, mean 17.7 +/- 9 years; body weight 30 to 87 kg, mean 51.4 +/- 16. The stretched balloon diameter of the defects ranged from 8 to 28 mm, mean 18.8 +/- 6.9; the diameter of the devices ranged from 10 to 30 mm, mean 20.8 +/- 6. Immediate total occlusion rate was 18.1%, rising to 63.6% after 24 hours. Total occlusion rate at one month reached 100%. Severe transient sinus bradycardia in one (9%) was the only complications. At follow-up (10 to 26 months, mean 13.2 +/- 5.0) all patients remain asymptomatic with no residual shunt. CONCLUSIONS: The Amplatzer septal occluder is very efficient and offered interventional interatrial communications closure in 100% of our group of consecutive patients with excellent intermediate results.

[Using fenestration and decompression technique to treat enormous odontogenic keratocyst].

3 cases of enormous odontogenic keratocyst were treated with the technique of fenestration and decompression other than removal of jaws. After a follow-up period of two years, radiographic assessment showed that the image of keratocyst disappeared basically, neogenetic bone had been found and the defect of jaws had been restored. The teeth had no dysfunction, the lower lip had no numbness and the keratocyst epithelium was modulated histologically to mucosa after decompression. Fenestration and decompression are satisfied conservative approaches to treat enormous keratocyst which usually is treated by removal of jaws and extraction of teeth.

Quadricuspid aortic valve with centrally fenestrated leaflets causing aortic insufficiency.

The occurrence of a quadricuspid aortic valve with single, central leaflet fenestrations causing aortic insufficiency has not previously been reported. We recently encountered these features during aortic valve replacement for severe aortic regurgitation in a 20-year-old man who had had a history of aortic insufficiency since age 2 years. The patient's late increase in symptoms was probably due to the fact that 1 of the 4 leaflets was somewhat flail, allowing incomplete coaptation and producing regurgitation over and above that caused by the central fenestrations.

Platypnea-orthodeoxia induced by fenestrated atrial septal aneurysm.

Platypnea-orthodeoxia is a peculiar syndrome characterized by a right-to-left shunt, which occurs in the upright position. The diagnosis is made by contrast transesophageal echocardiography, paying attention to include contrast visualization in the orthostatic decubitus. The association of this syndrome with a fenestrated atrial septal aneurysm is rare and probably underlies a peculiar and also rare mechanism of shunting in presence of normal pulmonary pressure. We report of a case of a 58-year-old man with a fenestrated atrial septal aneurysm and platypnea-orthodeoxia syndrome treated by surgical closure of the atrial defect.

Argon laser fenestration of a Softperm contact lens.

Contact lens fenestration can increase tear exchange. We describe a case in which a patient with 15 D of against-the-rule astigmatism was fit with a Softperm contact lens but was unable to wear it for more than 1 hour because of corneal edema. After fenestrating the Softperm lens with an argon laser the patient was able to wear her lens for 10 hours without signs of corneal decompensation.

Guided periodontal regeneration using bilayered collagen membranes and bovine bone mineral in fenestration defects in the canine.

This study was performed to evaluate the effect of deproteinized bovine porous bone mineral (BBM) and BBM-collagen (BBMC) used alone or in combination with a bilayer collagen membrane in guided periodontal regeneration. In 12 dogs, contralateral surgical circular fenestration defects 5 mm in diameter were produced at the midbuccal aspect of the alveolar bone in 24 maxillary canines. Bone, periodontal ligament, and cementum were completely removed. Experimental sites were filled with BBM or BBMC. Bilayered collagen membranes covered half the experimental sites (BBM+M and BBMC+M), and the other half were left uncovered. Control sites remained empty; half were covered with collagen membranes (cont+M) and the underlying space spontaneously filled with blood, and half were left uncovered (cont). Three months postsurgery, undecalcified sections were prepared. Measurements were made using a caliper on a projection microscope, and the surface area of new bone and BBM particles within the healed surgical defect was evaluated using the point-counting method. In the experimental defects, new cementum covered 31% to 67% of the exposed dentin, with a significant difference between defects covered with membranes and defects that were not covered (P < .05). New cementum in the control (unfilled) defects also differed significantly between covered and uncovered defects. New bone growth presented a pattern similar to the cementum. There was no statistical difference between defects treated with BBM and BBMC, within both covered and uncovered groups. There was less connective tissue in the covered defects than in the uncovered defects (P < .05). The defects were filled with new bone, new connective tissue/bone marrow, and bovine bone particles. New bone area fraction was 23.4% to 25.2% in defects filled with BBMC and BBM, respectively (P = NS). Bone fraction area in membrane-covered defects ranged from 34.4% to 36.8% in experimental defects (P = NS). All membrane-treated defects showed higher values for bone area fraction in comparison to the uncovered control defects. Particle area fraction ranged between 17.4% and 26.2%, with only BBMC and BBM+M defects showing a statistically significant difference (P < .05). Defects filled with submembranous blood clot exhibited significantly more new cementum and bone regeneration than experimental defects filled with BBM or BBMC. Treatment of defects with BBM or BBMC showed similar influences on bone and cementum regeneration in fenestration periodontal defects. The presence or absence of bilayered collagen membranes was the predominant factor influencing bone and cementum regeneration.

Cervical enamel projection with gingival fenestration in a maxillary central incisor: report of a case.

Bacterial plaque has been implicated as the primary etiologic factor in the initiation and progression of periodontal disease. Anatomic factors, such as cervical enamel projections, enamel pearls, and radicular grooves, are often associated with advanced localized periodontal destruction. Enamel projections and pearls are most often associated with molars, while radicular grooves are usually located on the palatal aspect of maxillary incisors. Gingival fenestrations are of uncertain etiology and have rarely been reported in the dental literature. An unusual case is presented of a cervical enamel projection located on the facial aspect of a maxillary central incisor in association with gingival fenestration. Rationale for therapy and likely healing results are discussed.

Airway obstruction by granulation tissue within a fenestrated tracheotomy tube: case report.

Complications of tracheotomy tube placement can be categorized as intraoperative, early postoperative, and late postoperative. Among the late complications is the development of granulation tissue. We describe one of the few reported cases of granulation tissue that formed within a fenestrated tracheotomy tube. In this case, the granulation tissue grew through the fenestrations, obliterated the tracheal lumen, and tethered the tube to the trachea itself. As a result, the patient required emergency treatment to restore airway patency.

Long-term roentgenographic and functional changes in patients who were treated with wide fenestration for central lumbar stenosis.

Thirty-four patients who had central stenosis of the lumbar spine were treated with wide fenestration, a procedure in which only the medial parts of the inferior facets and the adjoining ligamentum flavum were removed. The patients were followed for an average of five and one-half years (range, four and one-half years to seven years and ten months). Wide fenestration successfully relieved the symptoms. The new bone that was laid down in the operatively treated segments did not reproduce the symptoms of spinal stenosis; instead, it appeared to stabilize those segments.

Fenestrated capillaries in the ventral sebaceous gland of the Djungarian hamster, Phodopus sungorus.

The ventral sebaceous gland of the Djungarian hamster is a macroscopically visible organ situated in the midventral area of the abdominal wall. It consists of densely packed acini arranged in lobules with common excretory ducts. The rich vascular network of the gland is characterized by fenestrated capillaries. Fenestrated endothelium has not yet been reported as a characteristic and regular finding within sebaceous glands. Results are discussed with regard to proliferation rate of sebocytes and the demand of fluid and nutrient supply.

[Fenestrated rib fracture, a disease entity?].

The problems of the paradoxical respiration - observed in the case of fenestrated rib fracture - are discussed by the authors. On the basis of the data of the literature and of 348 own cases with covered rib fracture, as well as on the basis of the course and the clinical analysis of the lesion the authors refuse to admit the role of the "pendelluft" and of the mediastinal flutter in the development of circulatory and respiratory disorders occurring in the case of fenestrated rib fractures. In the authors' opinion, there are only quantitative differences between the consequences of the various rib fractures. The thoracal lesion is considered by the authors as functional unity. The treatment is always prescribed according to the degree of the functional disorder and also the classification of the injured patients is to be made on this basis.
