[Endovascular Repair of Aortic Injury Caused by Esophageal Foreign Body:Report of a Case].

A 51-year-old man visited to our hospital because of chest discomfort and hematemesis. He was diagnosed with Mallory-Weiss syndrome and followed in outpatient clinic. One week later, he visited our hospital again for fever and discomfort. Chest computed tomography (CT) showed a foreign body perforated in the mediastinum in the upper esophagus, and he was urgently hospitalized for surgical removal of esophageal foreign body. Before surgery he vomited the esophageal foreign body with a lot of blood. Hematemesis was stopped spontaneously and contrast-enhanced CT revealed a pseudoaneurysm in the distal aortic arch, so thoracic endovascular aortic repair (TEVAR) was performed to prevent rupture. Esophageal endoscopy found that the site of esophageal injury healed spontaneously, so the patient was followed conservatively with antibiotics. He was discharged on postoperative day 18 uneventfully. TEVAR was an effective treatment for aortic injury caused by esophageal foreign body in our case.

Open Surgical Repair for a Giant Common Hepatic Artery Aneurysm with Difficulty in Proximal Arterial Clamping: A Case Report.

Hepatic artery aneurysm has been considered as a rare, life-threatening disease. In this study, we report on a patient requiring surgical treatment for a giant hepatic artery aneurysm by aneurysmectomy without revascularization. A 70-year-old woman who complained of epigastric pain was referred to our hospital. Enhanced computed tomography scan has revealed a giant (11×9 cm) common hepatic artery aneurysm. She then underwent emergency surgery; the intra-aortic balloon occlusion technique was applied in order to control the blood inflow into the aneurysm. The aneurysm was then incised, and direct closure of the inflow and outflow orifices was performed safely without evidence of ischemic change in the liver.

[Structural Deterioration of a Bovine Pericardial Valve in a Tricuspid Position 14 Years Postoperatively;Report of a Case].

Although nonstructural dysfunction of a bioprosthesis caused by pannus formation or native valve attachment has been well described, structural valve deterioration( SVD) caused by calcification or tear of a bioprosthesis, especially a bovine pericardial valve, is very rare in the tricuspid position. We report a case of redo tricuspid valve surgery for SVD 14 years after tricuspid valve replacement( TVR) using a Carpentier-Edwards Perimount (CEP) pericardial valve. A 71-year-old woman was referred to our hospital because of exertional dyspnea and pre-syncope. She had undergone mitral valve replacement with a St. Jude Medical mechanical valve and TVR with a CEP pericardial valve 14 years previously. Transthoracic echocardiography revealed tricuspid valve stenosis with a mean trans-tricuspid valve pressure gradient (TVPG) of 7.3 mmHg. Redo TVR using a CEP Magna Mitral Ease valve was performed under cardiac arrest. Severe calcification was observed on the ventricular side of the leaflets of the explanted valve. The mean TVPG decreased to 3.2 mmHg after surgery, and the patient's postoperative course was uneventful.

Coronary Arteriovenous Fistula in Continuity With the Aortic Arch.

Coronary arteriovenous fistula in continuity with the aortic arch by abnormal vessels running along the surface of the pulmonary artery is rare. We describe 2 patients with this rare and unique arteriovenous network and discuss the issue of diagnosis and treatment with a review of the literature.

[Three Mitral Valve Operations in a Patient with Trousseau Syndrome and Nonbacterial Thrombotic Endocarditis Caused by Ovarian Cancer].

A 52-year-old woman was admitted to our hospital for acute right hemi-paresis, left homonymous hemianopia, and fever. Magnetic resonance imaging of the brain showed multiple cerebral infarctions and transesophageal echocardiography (TEE) revealed a vegetation on the posterior leaflet of her mitral valve. Mitral valve repair was performed under a diagnosis of infective endocarditis (IE). Further multiple cerebral infarctions occurred on the 11th postoperative day, resulting in left hemiplegia and dysarthria. TEE revealed vegetations on her mitral valve and mitral valve replacement (MVR) was performed. Microscopic examination of the resected valve showed mild lymphocytic infiltration, but no bacterial or fungal organisms were detected. On the 66th day after the initial surgery, she developed deep vein thrombosis and acute pulmonary embolism. Abdominal computed tomography showed a huge ovarian tumor, and TEE demonstrated vegetations on the left atrial wall, the aortic valve, and the mechanical valve immobilizing one of the leaflets. The patient was finally diagnosed as having Trousseau syndrome caused by an ovarian tumor and non-bacterial thrombotic endocarditis( NBTE). Three months after the initial operation, redo MVR was performed and aortic valve vegetations were removed. Four days later, the ovarian cancer was resected. Her postoperative course was uneventful and she was discharged on foot on the 143rd day after the initial operation. NBTE caused by malignancy is rare but must be considered when managing endocarditis.

Surgical repair of isolated anterior mitral leaflet cleft via right minithoracotomy.

Isolated anterior mitral leaflet cleft (AMLC) is rare. Several surgical procedures have been described; however, there are few reports which described mitral repair using minimally invasive cardiac surgery for AMLC. We describe successful repair for isolated AMLC via right minithoracotomy. A 29-year-old woman with moderate mitral regurgitation (MR) diagnosed by echocardiogram several years previously presented with dyspnea on exertion. Transthoracic echocardiography revealed severe MR due to an AMLC in the central portion of A2. An autologous pericardial patch augmentation combined with artificial chorda reconstruction under right minithoracotomy approach was performed. It enabled to gain adequate leaflet coaptation area, and MR was effectively controlled by these procedures. .

Impact of residual ethmoid cells on postoperative course after endoscopic sinus surgery for chronic rhinosinusitis.

OBJECTIVE: Endoscopic sinus surgery (ESS) is a worldwide standard surgical procedure for chronic rhinosinusitis (CRS). Residual ethmoid cells (RECs), which result from failure to completely remove them, have been thought to be a cause of recurrence of CRS. Our objective was to investigate the relationship between the REC score and post ESS recurrence of CRS. METHODS: From January 2002 through December 2003, a total of 138 consecutive CRS patients (86 men and 52 women; mean age: 44 years) underwent ESS at the Department of Otorhinolaryngology, Ota General Hospital. CT was performed at 6 or more months post ESS for all patients. The left and right ethmoid sinuses were each divided into superior-anterior, inferior-anterior and posterior parts. The extent of RECs in each part was assessed using a 3-grade scoring system. The outcome of CRS was classified into a satisfactory outcome group and a poor outcome group based on the improvement rate determined from the pre ESS and post ESS CT image findings. The two groups were then compared for the age, gender, presence/absence of nasal polyps, presence/absence of allergic rhinitis, presence/absence of asthma, the peripheral eosinophil count (%) and the total REC score. In addition, the individual correlations between the above variables and the poor outcome group were analyzed by logistic regression analysis. RESULTS: The total REC score was 0 in only 35 (25.4%) of the total patients. The most common total REC scores were 1-6 in 85 (61.6%) patients. The superior-anterior part had the largest number of patients with an REC score of 1 or more. The satisfactory outcome group comprised 97 patients (70.3%), while the poor outcome group comprised 41 patients (29.7%). Comparison of these two groups found that the peripheral eosinophil count, the prevalence rate of asthma and the total REC score were each significantly higher in the poor outcome group than in the satisfactory outcome group. Logistic regression analysis identified a peripheral eosinophil count of ≥9.5%, the presence of asthma and a total REC score of ≥4 as factors that correlated significantly with a poor outcome. CONCLUSION: The findings of this study indicate that RECs are involved in the recurrence of CRS following ESS. It can be thought that how to achieve full opening of the superior-anterior part of the ethmoid sinus, which includes the frontal recess, will be an issue in the future.
