We report a 6-month-old infant with pulmonary atresia with ventricular septal defect who was successfully treated with a novel technique of percutaneous major aortopulmonary collateral artery (MAPCA) banding with a covered stent. He suffered from heart failure due to a residual MAPCA of 4.5 mm in diameter. A covered stent tied with 2 5–0 size nylon threads was successfully deployed into the MAPCA in a dumbbell shape with a banding diameter of 2.8 mm. Banding covered stent implantation is a useful method to reduce the pulmonary blood flow in patients with MAPCA, which could be a less-invasive alternative to surgery. 相似文献

Background
Langerhans cell histiocytosis (LCH) is a clonal disease with focal or disseminated lesions that may compress the surrounding tissues, including the spinal cord. Because few reports have described the spinal symptoms as the first manifestation of pediatric LCH, the long-term neurological outcomes remain unclear.Case report and literature review
We report a 21-month-old boy who presented with sudden-onset paraplegia. Imaging analyses revealed that osteolytic lesions and epidural tumors compressing the spinal cord at the T7-9 vertebrae. Twelve days after he developed leg weakness, emergency radiotherapy was started after a tumor biopsy. During the course of radiotherapy, paralysis steadily ameliorated. After we excluded infections and determined the pathological diagnosis of LCH, multi-drug chemotherapy was started. Apparent improvement in his complete paraplegia was observed after a total 15?Gy of radiotherapy and subsequent chemotherapy, leaving no neurological sequelae at 4?years of age. Through a literature search of studies published from 1980 to 2017, we found that children with LCH showed a generally favorable recovery from neurological dysfunction after the acute phase of spinal symptoms.Conclusion
This report underscores the utility of emergency radiotherapy for the neurological recovery of spinal LCH in infants. Our long-term observation further denotes the value of this treatment in terms of the intact survival with preserved motor functions and physical growth. 相似文献94.

Background
The purpose of this study was to clarify the effect of preoperative chemoradiotherapy (CRT) for esophageal cancer on the postoperative course, and to determine the clinical significance of salvage esophagectomy after definitive CRT.Methods
Based on their preoperative treatment, 477 patients with esophageal cancer were classified into three groups: 253 patients who received surgery alone (Group I), 197 who received planned CRT (30?C45?Gy, Group II), and 27 who received a salvage esophagectomy (radiation ??60?Gy, Group III).Results
Postoperative complications developed in 25, 40, and 59% of the patients in Groups I, II, and III, respectively, with pulmonary complications developing in 10, 15, and 30%, and anastomotic leakage developing in 13, 23, and 37%, respectively. Mortality rates were 2.4, 2.0, and 7.4%, respectively. Multivariate analysis revealed preoperative therapy to be an independent factor associated with postoperative risks: the odds ratios (ORs) of Groups II and III compared to Group I were 1.8 and 4.0 for pulmonary complications, while they were 1.9 and 2.8, respectively, for anastomotic leakage. No critical complications developed in the 14 patients who received salvage surgery performed with strict surgical indications after 2005. The survival of Group III was not significantly different from that of Groups I and II. Most patients who received an R1/R2 resection after definitive CRT died within 2?years after salvage surgery.Conclusions
Preoperative CRT is associated with postoperative complications especially in patients with R2 resection, while long-term survival can be achieved after R0 resections. Salvage surgery should be considered for carefully selected patients in whom R0 resection can be achieved. 相似文献95.

Purpose: To investigate the interval between low-dose radiotherapy and radiation-induced cataracts, and the factors affecting this interval, in patients with lymphoproliferative disease of the ocular adnexa. Methods: A retrospective case series of 73 eyes of 59 patients who underwent radiotherapy from 1996 to 2005 with total doses ranging from 24 to 30 Gy was conducted. We investigated the relationships between the radiation-associated cataract formation intervals and age, gender, diabetes, and the use of corticosteroids. Results: The mean interval was 36 months. None of the patients with lens shield developed cataracts. Age was inversely and significantly and gender was not significantly associated with the interval from first radiotherapy to cataract occurrence. The intervals did not differ significantly according to the presence of diabetes and corticosteroid therapy. Conclusions: The mean interval from the start of radiation therapy to radiation-related cataract formation was 36 months and age was a significant factor affecting this interval. 相似文献

We report a case of postoperative recurrence of adenoid cystic carcinoma in the left parotid gland treated with radiotherapy
and arterial infusion chemotherapy. A 52-year-old woman had a history of surgical resection for an adenoid cystic carcinoma
arising from the left parotid gland 25 years before. Despite two reoperations for local recurrence after the initial surgery,
she had a third local recurrence in the remnant of the left parotid gland. The patient was treated with a concurrent combination
of radiotherapy (60 Gy/30F) and intraarterial infusion chemotherapy with carboplatin (750 mg/30 days) from which she obtained
a complete response. The patient has remained free of local progression 54 months after treatment. Radiotherapy and arterial
infusion chemotherapy is effective treatment for local recurrence of adenoid cystic carcinoma in the head and neck. 相似文献

The purpose of this study was to evaluate the treatment outcomes of stereotactic body radiotherapy (SBRT) for Stage I small-cell lung cancer (SCLC). From April 2003 to September 2009, a total of eight patients with Stage I SCLC were treated with SBRT in our institution. In all patients, the lung tumors were proven as SCLC pathologically. The patients'' ages were 58–84 years (median: 74). The T-stage of the primary tumor was T1a in two, T1b in two and T2a in four patients. Six of the patients were inoperable because of poor cardiac and/or pulmonary function, and two patients refused surgery. SBRT was given using 7–8 non-coplanar beams with 48 Gy in four fractions. Six of the eight patients received 3–4 cycles of chemotherapy using carboplatin (CBDCA) + etoposide (VP-16) or cisplatin (CDDP) + irinotecan (CPT-11). The follow-up period for all patients was 6–60 months (median: 32). Six patients were still alive without any recurrence. One patient died from this disease and one died from another disease. The overall and disease-specific survival rate at three years was 72% and 86%, respectively. There were no patients with local progression of the lesion targeted by SBRT. Only one patient had nodal recurrence in the mediastinum at 12 months after treatment. The progression-free survival rate was 71%. No Grade 2 or higher SBRT-related toxicities were observed. SBRT plus chemotherapy could be an alternative to surgery with chemotherapy for inoperable patients with Stage I small-cell lung cancer. However, further investigation is needed using a large series of patients. 相似文献
