1/2622. Postoperative gas bubble foot drop. A case report.STUDY DESIGN: An unusual case of foot drop occurring 10 days after disc surgery is reported. Imaging studies identified a gas bubble compressing the nerve root. OBJECTIVE: To describe the origin and management of a radiculopathy caused by an intraspinal gas bubble. SUMMARY OF BACKGROUND DATA: A recurrent lumbar disc herniation was diagnosed by clinical and imaging studies. A vacuum disc also was noted at the same level. These are common and not considered to be of pathologic significance. methods: The patient underwent a microdiscectomy for a lumbar disc extrusion. The postoperative course was excellent, with relief of symptoms and no neurologic deficit. Ten days later, the awoke with a foot drop and pain in the leg. Imaging studies showed a 4-mm gas bubble compressing the nerve root. Oral steroids were given for 10 days. RESULTS: Progressive improvement occurred, and the patient was asymptomatic 6 weeks later. Although in some instances it may be necessary to evacuate intraspinal gas, an initial period of observation is warranted, because the gas and its resulting symptoms may disappear spontaneously. CONCLUSION: Intradiscal gas accumulation, better known as vacuum disc, is considered to be a benign indication of degenerative disc disease. On occasion it can be a cause of symptoms. A case is reported in which gas leaked after surgery into the spinal canal, causing a foot drop. The symptoms and gas disappeared spontaneously without further treatment.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
2/2622. paraplegia after thoracotomy--not caused by the epidural catheter.BACKGROUND: paraplegia and peripheral nerve injuries may arise after general anaesthesia from many causes but are easily ascribed to central block if the latter has been used. CASE REPORT: A 56-yr-old woman, with Bechterev disease but otherwise healthy, was operated with left-sided thoracotomy to remove a tumour in the left lower lobe. She had an epidural catheter inserted in the mid-thoracic area before general anaesthesia was started. bupivacaine 0.5% 5 ml was injected once and the infusion of bupivacaine 0.1% with 2 micrograms/ml fentanyl and 2 micrograms/ml adrenaline (5 ml/h) started at the end of surgery. The patient woke up with total paralysis in the lower limb and sensory analgesia at the level of T8, which remained unchanged at several observations. laminectomy, performed 17 h after the primary operation, showed a large piece of a haemostatic sponge (Surgicel) compressing the spinal cord, which was then decompressed but the motor and sensory deficit remained virtually unchanged both then and a year later. CONCLUSIONS: This case shows--once again--that although central blocks may cause serious neurological complications and paraplegia, other causes are possible and have to be considered. However, all patients with an epidural catheter must be monitored for early signs and symptoms of an intraspinal process and the appropriate treatment has to be instituted instantly.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
3/2622. Idiopathic thrombocytopenic purpura after a living-related liver transplantation.BACKGROUND: Idiopathic thrombocytopenic purpura (ITP) is a rare complication after liver transplantation. We describe three cases of ITP in pediatric patients after a living-related liver transplantation (LRLT). methods: Of 266 patients who underwent an LRLT between June 1990 and June 1996, severe thrombocytopenia developed in three pediatric patients after transplantation, and ITP was also diagnosed. The original disease was biliary atresia in all cases, and the patients were given a partial liver graft from a living-related mother and subsequently treated with tacrolimus and low-dose steroids as an immunosuppressive regimen. RESULTS: The duration until the onset of ITP after transplantation in the three cases was 1 day, 3 months, and 13 months, respectively. The platelet-associated IgG levels increased in all cases. A preceding viral infection was suspected in two of the three cases. All patients were treated with intravenous gamma globulin with a transient recovery of thrombocytopenia in two cases and a sustained recovery in another. CONCLUSIONS: Transplant clinicians need to be aware of the possibility of ITP complication because a sudden onset of severe thrombocytopenia can occur even in patients who are apparently doing well after undergoing an LRLT.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
4/2622. Treatment for empyema with bronchopleural fistulas using endobronchial occlusion coils: report of a case.We report herein the case of a woman with bronchopleural fistulas treated with the endobronchial placement of vascular embolization coils. She was referred to our hospital to undergo lavage of a postoperative empyema. She had undergone an air plombage operation for pulmonary tuberculosis 9 years previously. However, bronchopleural fistulas occurred postoperatively and she had to continue the use of a chest drainage tube since then. Lavage of her empyema space with 5kE of OK-432 (picibanil: Chugai) plus 100 mg minocycline was performed once every 2 weeks for 3 months, and the purulent discharge from the empyema remarkably decreased. Thereafter, the bronchopleural fistulas were occluded endobronchially by the placement of vascular embolization coils. Soon after the procedure, air leakage from the fistulas was stopped and the drainage tube was removed 2 days later. The patient remains well without any additional treatment at 20 months after this treatment. As treatment for empyema with bronchopleural fistulas, it would be worth trying to lavage the empyema space with OK-432 until it is cleaned out and to plug the fistulas by the endobronchial placement of embolization coils, before such radical operations as thoracoplasty and space-filling of the empyema are considered.- - - - - - - - - - ranking = 1.4988042756541keywords = tube (Clic here for more details about this article) |
5/2622. Unaccountable severe hypercalcemia in a patient treated for hypoparathyroidism with dihydrotachysterol.This report describes a forty-seven-year-old female patient with a complex medical history. She was suffering from an unspecified interstitial lung disease, papillary thyroid carcinoma which had been treated, hypoparathyroidism after thyroidectomy for which she was receiving dihydrotachysterol and calcium, and atrial fibrillation and congestive heart failure as a result of mitral stenosis. Shortly after mitral valve replacement she developed a severe hypercalcemia (serum calcium 5.95 mmol/l) during a febrile illness. At that time anti-tuberculous agents were also being administered for presumed tuberculosis. The possible mechanisms for this severe elevation of the calcium level are discussed. immobilization, while Paget's bone disease was present, and perhaps enhanced activation of dihydrotachysterol by rifampicin, could have led to increased calcium-release into the circulation. Continuous supplecation of calcium and vitamin d, provoked dehydration and the mechanism of the milk-alkali syndrome also contributed to this extremely high calcium level. It is concluded that hypoparathyroid patients being treated with vitamin d and calcium should be carefully monitored in the case of an intercurrent illness or a change in medication.- - - - - - - - - - ranking = 2.9992028504361keywords = disease, tube (Clic here for more details about this article) |
6/2622. Fatal cardiac ischaemia associated with prolonged desflurane anaesthesia and administration of exogenous catecholamines.PURPOSE: Four cardiac ischaemic events are reported during and after prolonged anaesthesia with desflurane. CLINICAL FEATURES: We have evaluated desflurane in 21 consecutive patients undergoing advanced head and neck reconstructive surgery. Four deaths occurred which were associated with cardiac ischaemic syndromes either during or immediately after operation. All patients in the study received a similar anaesthetic. This comprised induction with propofol and maintenance with alfentanil and desflurane in oxygen-enriched air. Inotropic support (either dopamine or dobutamine in low dose, 5 micrograms.kg.min-1) was provided as part of the anaesthetic technique in all patients. Critical cardiovascular incidents were observed in each of the four patients during surgery. These were either sudden bradycardia or tachycardia associated with ST-segment electrocardiographic changes. The four patients who died had a documented past history of coronary heart disease and were classified American Society of Anesthesiologists (ASA) II or III. One patient (#2) did not survive anaesthesia and surgery and the three others died on the first, second and twelfth postoperative days. Enzyme increases (CK/CK-MB) were available in three patients and confirmed myocardial ischaemia. CONCLUSION: These cases represent an unexpected increase in the immediate postoperative mortality for these types of patients and this anaesthetic sequence.- - - - - - - - - - ranking = 1keywords = disease (Clic here for more details about this article) |
7/2622. Haemopericardium as a late complication in anticoagulant therapy following mitral valve replacement.Two patients, who suffered from pericardial tamponade in the course of prophylactic anticoagulant treatment, are reported. The mitral valve had been replaced by a prosthesis in both cases. The diagnosis was suspected clinically and radiologically and proven by pericardiocentesis. One of the patients was treated by a percutaneously inserted small polyethylene tube for continous drainage and the other by thoracotomy and partial pericardiectomy. Both patients recovered and are at present asymptomatic. Th mechanism of bleeding patients receiving anticoagulant therapy is briefly discussed.- - - - - - - - - - ranking = 0.49960142521803keywords = tube (Clic here for more details about this article) |
8/2622. Anatomical and embryological considerations in the repair of a large vertex cephalocele. Case report.The case of a neonate with a large vertex cephalocele is presented. The anatomical features of this anomaly were evaluated by means of magnetic resonance imaging and magnetic resonance angiography. Fusion of the thalami, dysgenesis of the corpus callosum, and failure of adequate formation of the interhemispheric fissure were characteristics of the major cerebral anomalies associated with the cephalocele. The absence of a falx in the midline, a split configuration of the superior sagittal sinus, and a dysgenetic tentorium with a concomitant abnormal venous drainage pattern were found in association with a large dorsal cyst. Repair of the anomaly was undertaken on the 3rd postnatal day. A cerebrospinal fluid shunt was required to treat hydrocephalus on Day 30. The child is well at age 3 years, but with significant developmental delay. The pathogenesis of this vertex cephalocele relates to semilobar holoprosencephaly and dorsal cyst formation. In addition, a disturbance in the separation of the diencephalic portion of the neural tube from the surface ectoderm or skin during the final phases of neurulation had occurred to help create the large cephalocele. Detailed preoperative imaging studies and awareness of the embryology and anatomy of this lesion facilitated the repair of the cephalocele. The prognosis of the child is determined not only by the presence of hydrocephalus, but also by the number of associated major cerebral anomalies. Options for treatment are discussed.- - - - - - - - - - ranking = 0.49960142521803keywords = tube (Clic here for more details about this article) |
9/2622. artifacts in magnetic resonance images following anterior cervical discectomy and fusion: report of two cases.Magnetic susceptibility artifacts in two patients who underwent anterior cervical discectomy with fusion for cervical intervertebral disc prolapse are described. These artifacts located at the previously operated level suggested severe ventral compression of the dural tube. Computed tomography (CT) confirmed the artifactual nature of the MR findings and delineated the possible cause for the recurrence of symptoms in these patients. elements and factors that can possibly lead to MR susceptibility artifacts in post operative imaging are elucidated. The danger of using MR imaging alone in directing the management of these patients is highlighted.- - - - - - - - - - ranking = 0.49960142521803keywords = tube (Clic here for more details about this article) |
10/2622. Isolated tuberculosis of the pancreas after orthotopic liver transplantation.A patient presented with intermittent high fever, upper abdominal pain, and loss of appetite 9 months after an orthotopic liver transplantation. Computed tomography showed a large mass in the pancreas that was confirmed at laparotomy. Pathological examination of the pancreatic biopsy specimen showed several chronic granulomatous lesions with caseating necrosis. Two and one half months after beginning antituberculous treatment, there was an important reduction of the pancreatic mass.- - - - - - - - - - ranking = 2.4980071260902keywords = tube (Clic here for more details about this article) |
