Abstract A two and a half year old girl who had undergone the Yasui procedure as a neonate for ventricular septal defect, subaortic stenosis, and interrupted aortic arch underwent follow‐up catheterization 2 years postoperatively. It showed that the neo‐left ventricular tract reconstructed by Damus‐Kaye‐Stansel anastomosis had occluded due to closure of the ventricular septal defect and residual subaortic stenosis at the original left ventricular outflow tract. The patient therefore underwent takedown of the Yasui procedure . (J Card Surg 2010;25:417‐418)相似文献
BackgroundThere is limited information on perioperative renal function during off-clamp, non-renorrhaphy open partial nephrectomy. Therefore, this retrospective study aimed to identify predictive factors of perioperative decline in renal function after off-clamp, non-renorrhaphy open partial nephrectomy.MethodsClinical records of 138 patients with renal tumors who underwent off-clamp, non-renorrhaphy open partial nephrectomy at our institution were reviewed. Off-clamp, non-renorrhaphy partial nephrectomy was performed using a soft coagulation system. Perioperative estimated glomerular filtration rate (eGFR) preservation was calculated, and predictors were identified using multivariate regression analysis at 5 days, 1 month, and 3 months after surgery.ResultsThe median operation time was 122 minutes, and the median volume of estimated blood loss was 155 mL. The mean eGFR preservation at 5 days, 1 month, and 3 months after surgery was 95.3%, 91.0%, and 90.7%, respectively. Estimated blood loss was an independent predictor of perioperative decline in eGFR 5 days after surgery [odds ratio (OR): 0.97; 95% confidence interval (CI): 0.96, 0.98; P<0.001]. Preoperative eGFR and estimated blood loss were independent predictors of perioperative decline in eGFR 1 month after surgery (OR: 0.86; 95% CI: 0.77, 0.95; P=0.007 and OR: 0.98; 95% CI: 0.97, 0.99; P<0.001, respectively). Age, preoperative eGFR, and estimated blood loss were independent predictors of perioperative decline in eGFR 3 months after surgery (OR: 0.64; 95% CI: 0.54, 0.81; P<0.001, OR: 0.72; 95% CI: 0.61, 0.85; P<0.001; and OR: 0.98; 95% CI: 0.97, 0.99; P=0.004, respectively).ConclusionsEstimated blood loss during surgery was a predictor of perioperative decline in eGFR within 3 months after off-clamp, non-renorrhaphy open partial nephrectomy. Age was a predictor of perioperative decline in eGFR 3 months after surgery. 相似文献
Residual pancreatic B-cell function was investigated in children with diabetes mellitus in whom classification of the type of disease was difficult at the first visit. Intravenous glucagon tests were performed at the first visit and subsequently, the C-peptide responses compared. Based on our data on a limited number of patients, we propose C-peptide concentrations of 3.0 to 3.5 ng/ml at the peak or at 6 min after injection of glucagon, as the critical level which distinguishes non-insulin dependent from insulin-dependent diabetes mellitus. However, the degree of obesity, clinical stage and other factors also need to be considered in the classification of diabetes mellitus. 相似文献
Superficial temporal artery-to-middle cerebral artery (STA-MCA) anastomosis is a common procedure for neurosurgeons. The surgery necessarily requires accurate and speedy manipulation of microscope, for which a specific training is needed. Unexpected bypass occlusion sometimes happen during surgery.
Objective
Generally, conventional interrupted or continuous suture has been used for vascular anastomosis, despite various ideas have been attempted in the other surgery fields. We propose a horizontal mattress suture technique for intracranial microvascular bypass surgery. This is the first report ever published on intracranial vascular anastomosis.
Methods
We had four patients of STA-MCA bypass surgery with “mattress anastomosis” from March to May of 2012.
Results
During the procedure, there was no bypass occlusion and good patency was confirmed in all cases.
Conclusion
Intimae of the recipient and the donor blood vessel contact each other precisely with this technique. Although a long-term assessment of patency is needed, it is useful for the intracranial bypass surgery. 相似文献
Primary small cell carcinoma of the prostate is extremely rare. Herein reported is a case of primary small cell carcinoma of the prostate with immunohistochemical examination of KIT and platelet‐derived growth factor‐α. The present case is unique in that the small cell carcinoma did not express neuroendocrine antigens. A 68‐year‐old man was found to have high serum prostate‐specific antigen, and biopsy showed malignant small tumor cells fulfilling the small cell carcinoma criteria of the World Health Organization. Immunohistochemically, tumor cells were positive for pan‐cytokeratin, KIT, platelet‐derived growth factor‐α, p53, Ki‐67 labeling = 65%, prostate‐specific antigen and alpha‐methylacyl‐CoA racemase. Tumor cells were negative for vimentin, CD56, synaptophysin, chromogranin and neuron‐specific enolase. Imaging modalities showed multiple metastases, and the patient was treated by chemotherapy. The present report is the fifth with immunohistochemistry of prostatic small cell carcinoma. 相似文献
We report adult congenital bronchoesophageal fistula with both symptomatic fistula and asymptomatic one. A 56-year-old woman
with a history of cough after drinking fluids was diagnosed as bronchoesophageal fistula by upper gastrointestinal series
that showed a diverticulum in the middle portion of the esophagus with a fistula between the esophagus and right lower lung.
Esophagoscopy revealed an orifice of the fistula located 27 cm from the incisors. Computed tomography showed chronic inflammatory
change with bronchiectasis in the S6 segment of the right lung. The patient underwent video assisted thoracic surgery that
identified two fistulae without missing a symptomatic one, and both were successfully resected. The fistulae were lined by
squamous epithelium and smooth muscle without evidence of malignancy, infection or chronic inflammation that were histologically
compatible with congenital fistulae. 相似文献
In the treatment of an intracranial aneurysm with the flow diverter, the combined use of coil embolization can help promote subsequent progressive thrombosis within the aneurysm sac and reduce the risk of delayed aneurysm rupture. This study retrospectively reviewed outcomes of patients who had undergone the Pipeline Embolization Device (PED) with adjunctive coil embolization (PED/coil) at a single center to determine its safety and efficiency. Patients with internal carotid artery aneurysms following an intradural component were selected for PED/coil between 2015 and 2020. All patients were premedicated with dual antiplatelet therapy of aspirin plus clopidogrel or prasugrel. A minimal number of PEDs were deployed, with coils inserted using a stent-jail technique, avoiding dense packing. A total of 46 aneurysms (43 patients; median dome size, 11.6 mm; median neck width, 6.3 mm) were treated with PED/coil. The median volume embolization ratio was 14.8%. The degree of angiographic filling at the 6-month and latest angiography showed complete occlusion in 60.5% (26/43) and 70.5% (31/44), respectively. Small (<?10 mm) aneurysms achieved a higher complete occlusion rate in the early period; a lower cumulative incidence of aneurysm occlusion was observed in large and giant (≥?10 mm) aneurysms (P?=?.024). The median clinical follow-up was 22 months, and no aneurysm ruptures occurred. Favorable clinical outcomes were achieved, with permanent neurological morbidity of 4.7% and no mortality. PED/coil demonstrated a high angiographic occlusion rate at an early stage. Loosely packed coils are sufficient to obliterate aneurysms effectively.
