Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

PURPOSE: To evaluate the efficacy of the combination therapy of intravitreal bevacizumab injection and photodynamic therapy in neovascular age-related macular degeneration associated with large retinal pigment epithelial detachment. METHODS: A total of 13 eyes were reviewed, with 9 eyes diagnosed with definite choroidal neovascularization (CNV) and 4 eyes diagnosed with CNV or polypoidal choroidal vasculopathy (PCV) becausethe exact type could not be determined. Photodynamic therapy was performed within 1 week after bevacizumab injection according to indocyanine green angiography (ICGA). Additional bevacizumab injections were performed within a 4 to 6 week interval. Additional photodynamic therapy was performed within 4 months. RESULTS: The visual acuity on final examination had improved in 3 eyes (23.1%), was maintained in 7 eyes (53.8%), and decreased in 3 eyes (23.1%). The change of the PED before and after treatment showed regression in 5 eyes (38.5%), recurrence after regression in 2 eyes (15.4%), persistence in 4 eyes (30.8%), and retinal pigment epithelial tear in 2 eyes (15.4%). The maintained or improved visual acuity rate was 66.7% (6/9) and 100% (4/4) in the CNV and CNV or PCV group, respectively. CONCLUSIONS: The combination therapy in neovascular age-related macular degenerationassociated with large retinal pigment epithelial detachment is a viable alternative treatment in the stabilization and improvement of vision. However, further studies with long-term follow up and controlled studies with anti-vascular endothelial growth factor antibody monotherapy are required.

PURPOSE: The aim of this study was to examine the relationship between tooth loss and sub-clinical atherosclerosis in Korean adults. MATERIALS AND METHODS: The subjects were part of a cohort study conducted in Ansan city by the Korea University medical school as part of the Korean Genome project. 749 subjects over than 40 years old were evaluated. After taking panoramic radiography, the amount of tooth loss was calculated. The intima-media thickness (IMT) was assessed by using ultrasonography at the common carotid artery. Traditional cardiovascular risk factors for atherosclerosis were also evaluated. The relationship between tooth loss and the IMT was evaluated using ANOVA with Scheffe's multiple comparison method in univariate analysis. Multiple regression analysis was also performed to determine the significance between the IMT and tooth loss. RESULTS: With age, tooth loss increased, but there was no significant increase in other traditional cardiovascular risk factors. Univariate analysis revealed the IMT to be positively related with the amount of tooth loss. Regression analysis of the IMT in the anterior and posterior tooth loss revealed that only the posterior tooth loss was significantly related with the IMT at all sites of the common carotid artery (right far wall, P = .015; left far wall, P = .008; right near wall, P < .001; left near wall, P = .001). CONCLUSION: This study verified the positive relationship between the increased tooth loss at the posterior area and the accumulation of atheroma in arteries.

A 42 year-old male with a history of multidrug-resistant pulmonary tuberculosis suddenly developed massive hemoptysis. Embolization of a bronchial artery branch and the collateral systemic arteries did not resolve the recurrent bleeding. Spiral computerized tomography(spiral CT) of the chest showed contrast enhanced nodules within a large cavity at the left lower lobe in the arterial phase suggesting a Rasmussen aneurysm. A pulmonary angiogram showed abnormal vascular nodules at that site. Coils were deployed at both the proximal and distal vessels of this aneurysmal sac for embolization. Transcatheter arterial embolization is a safe and effective means of controlling bleeding from this pulmonary arterial pseudoaneurysm. Here we report a case of a Rasmussen aneurysm diagnosed by spiral CT, which was successfully treated by pulmonary arterial embolization with a coil.

PURPOSE: To review the radiological findings of retroanastomotic hernia and to derive the useful US and CT criteria to assist in the diagnosis of the condition in patients who had previously undergone gastrojejunostomy. METHODS: During a recent period, 8 consecutive cases of retroanastomotic hernia were encountered. Of the patients involved, seven underwent US and CT imaging. The US and CT scans were reviewed retrospectively to determine the abnormal findings. Surgical confirmation was available in all cases. RESULTS: The efferent loop was herniated through the defect created behind the anastomosis in seven cases, and the afferent loop in one case. Retroanastomotic hernia was suggested prospectively in all cases. Among the seven cases of efferent loop herniation, the US and CT signs of retroanastomotic hernia included whirling of the mesenteric vessels, jejunal loops, and mesentery in the periumbilical abdomen (7/7); mural thickening of the herniated bowel loops (5/7); dilatation of the herniated bowel loops (2/7); and US showed decreased peristalsis of the herniated bowel loops (2/6). In one case, the US and CT signs of retroanastomotic hernia of the afferent loop included dilatation and whirling of a short length of the afferent loop behind the anastomosis. One out of the eight patients had reVersible bowel ischemia, and one had bowel necrosis. CONCLUSION: Retroanastomoic hernia is an important condition, and the US and CT findings might be used for its diagnosis.

PURPOSE: To report the clinical results of a planned vitrectomy, laser photocoagulation and gas tamponade for the treatment of serous macular detachment associated with optic disc pit. However, laser photocoagulation was performed on a postoperative outpatient basis for subretinal fluid. CASE SUMMARY: A 13-year-old women presented with central visual disturbance in the left eye. Her best-corrected visual acuity (BCVA) was 0.16. On ophthalmic examination, the patient was diagnosed with optic disc pit combined with serous macular detachment. After 3 months, the serous macular detachment increased and visual acuity decreased to 0.1. Pars plana vitrectomy combined with complete posterior vitreous detachment was performed. After intravitreal injection of perfluorodecalin, internal drainage of the subretinal fluid using the back flush needle around the optic disc pit was performed, but the fluid was not drained. The planned intraoperative photocoagulation was not performed due to a large serous macular detachment. Gas tamponade was performed and a facedown position was maintained for 1 week followed by laser photocoagulation. The subretinal fluid was completely absorbed and visual acuity was improved. In addition, recurrence was not observed throughout the follow-up period.

We report a case of posttraumatic intestinal stenosis (PIS), an uncommon sequela of blunt abdominal trauma, in which injury to the mesentery and bowel wall results in later focal ischemic stricture of that segment. We present CT images at the time of trauma and 3 weeks later when clinical signs of intestinal obstruction occurred. At surgery, a stenotic small bowel loop was found adjacent to a healed defect in the mesentery. Histologic examination of the resected segment showed mucosal and submucosal ischemia with mucosal ulceration, mural inflammation, and fibrosis. PIS subsequent to a mesenteric tear should be included in the differential diagnosis for a patient with a history of blunt abdominal trauma and signs of intestinal obstruction.

A rare small cell carcinoma of the trachea was managed in a 59 year old female patient. The diagnosis was confirmed by histopathological and immunohistochemical studies. Surgical resection and adjuvant chemotherapy were done. The patient died 6 months later due to multiple metastasis.
