Complicated stent supported cerebrovascular angioplasty: case analyses and review of literature 总被引:2,自引:0,他引:2
Koenigsberg RA Dave A McCormick D Weiss J Higashida RT Faro SH Grandinetti LM Tsai FY 《Surgical neurology》2000,53(5):465-474
BACKGROUND: Hemodynamic lesions of the cervicocerebral vasculature are currently being treated with stent supported percutaneous transluminal angioplasty. These procedures have met with increasing success when compared to the risks and morbidity of more invasive surgical approaches. The versatility of stent-supported angioplasty as a primary therapeutic modality is examined in the following complex cases. CASE DESCRIPTION: We present four cases involving cervical angioplasty with emergent or adjunctive stent placement. Two cases involved the subclavian arteries, whereas the others involved the vertebral and internal carotid arteries. In our experience, complications of cervicocerebral artery angioplasty have been successfully managed by stent placement. CONCLUSION: Our cases demonstrate the emerging role of cervical angioplasty and stent implantation as a successful therapeutic modality, highlighted in these complex cases. 相似文献

Immune deficiencies in chronic intestinal pseudo-obstruction 总被引:1,自引:0,他引:1

Aim: Chronic intestinal pseudo-obstruction has been associated with urinary disorders, myopathy, and ophthalmoplegia in adults and cholelithiasis in children. We observed a high percentage of total-parenteral-nutrition-dependent patients with pseudo-obstruction and recurrent infections requiring gammaglobulin infusions. Methods: AH records for 23 children with chronic intestinal pseudo-obstruction (10 females and 13 males, mean age 9.8 y ± 4.9 y, range 4–24 y) referred for a nutritional evaluation from 1992 to 1995 were reviewed. Chronic intestinal pseudo-obstruction was diagnosed by clinical, radiographic findings and antroduodenal manometry. Intestinal full-thickness biopsies were performed in seven children. Results: Hypogammaglobulinemia was diagnosed in 18 patients (78%): 16 patients had various immunoglobulin deficiencies and 2 had selective antibody deficiency. Intravenous gammaglobulin was administered in 14 patients. Other medical conditions affecting the children are summarized as follows: autonomic dysfunction in 10 patients (43%), recurrent hypoglycemia in 9 (39%), asthma in 9 (39%), cholecystitis in 7 (30%), low serum carnitine level in 6 (26%), urinary dysfunction in 6 (26%), pancreatitis in 5 (22%), behavioral problems in 5 (22%), myopathy in 2 (9%), idiopathic thrombocytopenia in 2 (8%), velopharyngeal insufficiency in 1 (4%), oculocutaneous albinism in 1 (4%), Pierre-Robin syndrome in 1 (4%), and protein C deficiency in 1 (4%). Munchausen syndrome was suspected in two patients. Conclusions: Chronic intestinal pseudo-obstruction appears to be associated with immune deficiencies. It is unclear if the immune deficiencies, intestinal pseudo-obstruction, and the other medical conditions have a common underlying etiology. Repeated infections may be due to impaired immune function in children with chronic intestinal pseudo-obstruction. We recommend screening for immune deficiencies in children with chronic intestinal pseudo-obstruction. 相似文献

This experiment investigated whether neonatal isolation stress alters central concentrations of progestins. Whole brain progesterone (P), dihydroprogesterone (DHP), and allopregnanolone (3alpha, 5alpha-THP) were measured in pups that were isolated from the nest, dam, and siblings for 1 h on postnatal days (PND) 2-9 and were compared to control litters of pups that were not isolated. Isolated 2-day-old pups had significantly lower central P and higher P to DHP and 3alpha, 5alpha-THP metabolism ratios. On PND 9, pups that had been repeatedly isolated (PND 2-8), had significantly lower whole brain DHP and significantly greater whole brain 3alpha, 5alpha-THP compared to controls. Thus, the biosocial stress of isolation in neonatal rats alters central pregnane steroids. 相似文献
