1/177. Coiling of recurrent and residual cerebral aneurysms after unsuccessful clipping.We treated four patients with 3 recurrent and 1 residual aneurysm after surgical clipping by using Guglielmi detachable coils (GDCs). Three subjects presented after a second subarachnoid hemorrhage (SAH) occurring between 10 and 25 years after the first bleeding. Early postoperative angiography of the fourth patient showed an incompletely clipped aneurysm. In three poor grade patients we observed one good outcome, one fair result and one death due to the sequelae of SAH. One good grade patient remained in excellent condition postoperatively. Three aneurysms were totally occluded and in one a more than 90% occlusion was achieved with GDCs. We consider the treatment with GDC a viable alternative to reoperation in all patients with recurrent or residual aneurysms following failed attempt at surgical obliteration.- - - - - - - - - - ranking = 1keywords = subarachnoid (Clic here for more details about this article) |
2/177. Carotid ligation for carotid aneurysms.Thirty patients with subarachnoid haemorrhage due to rupture of a carotid aneurysm were treated by ligation of the common carotid artery. Two patients died as a result of the procedure, two patients developed persisting hemisphere deficit. Eight of the ten patients who developed cerebral ischemia after the operation were operated within ten days after the bleeding. At present out aim is to guide the patient safely through the first ten days after his haemorrhage and perform ligation at the end of the second week. After a follow up period of 1-8 years recurrent haemorrhage did not occur. Common carotid ligation, preferably with control of carotid artery end pressure, cerebral blood-flow and EEG is considered to be a valuable method to treat ruptured intracranial carotid aneurysm.- - - - - - - - - - ranking = 7.8272260747943keywords = subarachnoid haemorrhage, haemorrhage, subarachnoid (Clic here for more details about this article) |
3/177. Fatal haemorrhage from Dieulafoy's disease of the bronchus.A 70 year old woman with a previous history of healed tuberculosis and suspected chronic obstructive pulmonary disease presented with recurrent haemoptysis and respiratory failure from a lobar pneumonia. Massive bleeding occurred when biopsy specimens were taken during bronchoscopy which was managed conservatively, but later there was a fatal rebleed from the same site. Two different Dieulafoy's vascular malformations were found in the bronchial tree at necropsy, one of which was the biopsied lesion in the left upper lobe. This report confirms the possibility that vascular lesions occur in the bronchial tree. It is suggested that, if such lesions are suspected at bronchoscopy, bronchial and pulmonary arteriography with possible embolotherapy should be performed.- - - - - - - - - - ranking = 4.622224480825keywords = haemorrhage (Clic here for more details about this article) |
4/177. Congenital malformation of the inner ear associated with recurrent meningitis.Congenital deformities of the labyrinth of the inner ear can be associated with meningitis and varying degrees of hearing loss or deafness. A recurrence of meningitis is due to the development of a fistulous communication between the subarachnoid space and the middle ear cavity, and can prove lethal. An illustrative case of a 4-year-old Japanese girl with bilateral severe hearing loss, recurrent meningitis and malformations of the inner ear and stapes footplate is presented. Removal of the stapes during tympanotomy provoked a gush of cerebrospinal fluid. The defect was repaired successfully, and there has been no further episodes of meningitis to date.- - - - - - - - - - ranking = 1keywords = subarachnoid (Clic here for more details about this article) |
5/177. Rosai-Dorfman disease presenting as a pituitary tumour.A 45-year-old woman had pyrexia, headaches, collapse and hyponatraemia. Intracerebral abscess, bacterial meningitis and subarachnoid haemorrhage were excluded. She was given intravenous antibiotics and gradually recovered. One month later she was readmitted with diplopia, headache and vomiting. serum sodium was low (107 mmol/l) and a diagnosis of inappropriate ADH secretion was made. MRI scan showed a suprasellar tumour arising from the posterior pituitary gland. A skin rash gradually faded. serum cortisol, prolactin, gonadotrophins and thyroid hormone levels were low. A pituitary tumour was removed trans-sphenoidally, she had external pituitary radiotherapy, and replacement hydrocortisone and thyroxine. She was well for 12 months when she developed progressive weakness and numbness of both legs. Examination suggested spinal cord compression at the level of T2 where MRI scanning showed an intradural enhancing mass. This spinal tumour was removed and her neurological symptoms disappeared. Nine months after this she developed facial pain and nasal obstruction. CT scan showed tumour growth into the sphenoid sinus and nasal cavities. A right Cauldwell-Luc operation was done and residual tumour in the nasal passages was treated by fractionated external radiotherapy and prednisolone. Histological examination of the specimens from pituitary, spinal mass, and nasal sinuses showed Rosai-Dorfman disease, a rare entity characterized by histiocytic proliferation, emperipolesis (lymphophagocytosis) and lymphadenopathy. aged 48 she developed cranial diabetes insipidus. Although Rosai-Dorfman syndrome is rare, it is being reported with increasing frequency, and should be borne in mind as a possible cause of a pituitary tumour.- - - - - - - - - - ranking = 5.5161138343818keywords = subarachnoid haemorrhage, haemorrhage, subarachnoid (Clic here for more details about this article) |
6/177. Fatal pulmonary haemorrhage during anaesthesia for bronchial artery embolization in cystic fibrosis.Three children with cystic fibrosis (CF) had significant pulmonary haemorrhage during anaesthetic induction prior to bronchial artery embolization (BAE). Haemorrhage was associated with rapid clinical deterioration and subsequent early death. We believe that the stresses associated with intermittent positive pressure ventilation (IPPV) were the most likely precipitant to rebleeding and that the inability to clear blood through coughing was also an important factor leading to deterioration. Intermittent positive pressure ventilation should be avoided when possible in children with CF with recent significant pulmonary haemorrhage.- - - - - - - - - - ranking = 6.9333367212375keywords = haemorrhage (Clic here for more details about this article) |
7/177. Early rebleeding from intracranial dural arteriovenous fistulas: report of 20 cases and review of the literature.OBJECT: In this study the authors sought to estimate the frequency, seriousness, and delay of rebleeding in a homogeneous series of 20 patients whom they treated between May 1987 and May 1997 for arteriovenous fistulas (AVFs) that were revealed by intracranial hemorrhage (ICH). The natural history of intracranial dural AVFs remains obscure. In many studies attempts have been made to evaluate the risk of spontaneous hemorrhage, especially as a function of the pattern of venous drainage: a higher occurrence of bleeding was reported in AVFs with retrograde cortical venous drainage, with an overall estimated rate of 1.8% per year in the largest series in the literature. However, very few studies have been designed to establish the risk of rebleeding, an omission that the authors seek to remedy. methods: Presenting symptoms in the 20 patients (17 men and three women, mean age 54 years) were acute headache in 12 patients (60%), acute neurological deficit in eight (40%), loss of consciousness in five (25%), and generalized seizures in one (5%). Results of the clinical examination were normal in five patients and demonstrated a neurological deficit in 12 and coma in three. Computerized tomography scanning revealed intracranial bleeding in all cases (15 intraparenchymal hematomas, three subarachnoid hemorrhages, and two subdural hematomas). A diagnosis of AVF was made with the aid of angiographic studies in 19 patients, whereas it was a perioperative discovery in the remaining patient. There were 12 Type III and eight Type IV AVFs according to the revised classification of Djindjian and Merland, which meant that all AVFs in this study had retrograde cortical venous drainage. The mean duration between the first hemorrhage and treatment was 20 days. Seven patients (35%) presented with acute worsening during this delay due to radiologically proven early rebleeding. Treatment consisted of surgery alone in 10 patients, combined embolization and surgery in eight, embolization only in one, and stereotactic radiosurgery in one. Three patients died, one worsened, and in 16 (80%) neurological status improved, with 15 of 16 AVFs totally occluded on repeated angiographic studies (median follow up 10 months). CONCLUSIONS: The authors found that AVFs with retrograde cortical venous drainage present a high risk of early rebleeding (35% within 2 weeks after the first hemorrhage), with graver consequences than the first hemorrhage. They therefore advocate complete and early treatment in all cases of AVF with cortical venous drainage revealed by an ICH.- - - - - - - - - - ranking = 1keywords = subarachnoid (Clic here for more details about this article) |
8/177. An adult case of recurrent arteriovenous malformation after "complete" surgical excision: a case report.BACKGROUND: Complete surgical excision of arteriovenous malformations (AVM) documented by postoperative angiography is considered a cure. However, recent reports have shown that AVMs in children may recur after negative postoperative angiograms, and some suggest that it may reflect the immaturity of their cerebrovasculature. This case report demonstrates that AVM in adults may also recur, despite postoperative angiograms confirming complete removal. CASE DESCRIPTION: This 28-year-old man presented in 1994 with a focal motor seizure and was found to have an AVM in the right frontal lobe. He underwent surgical excision of the AVM; postoperative angiograms taken immediately after surgery and 15 days later showed no residual AVM. He remained free of symptoms after surgery and it was considered that a complete removal had been achieved. In 1998 he developed a subarachnoid hemorrhage, and subsequent angiograms revealed a small AVM in an adjacent location. CONCLUSION: This is the oldest patient reported in the literature with a recurrence of AVM, despite postoperative angiograms confirming complete removal. Angiographically invisible immature vessels, which might have been left in the surgical field, might have formed a new malformation later. We still believe that such recurrence must be very rare after AVM surgery, but we now recommend follow-up angiography at yearly intervals to our patients.- - - - - - - - - - ranking = 1keywords = subarachnoid (Clic here for more details about this article) |
9/177. Haemosuccus pancreaticus due to mucinous cystadenocarcinoma: the significance of recurrent abdominal pain, hyperamylasaemia and a pancreatic cyst in association with recurrent gastrointestinal bleeding.Haemosuccus pancreaticus is a rare cause of gastrointestinal haemorrhage, and when it presents in otherwise healthy people, can prove difficult to diagnose. The cardinal features are episodic epigastric pain associated with a raised serum amylase and the passage of melaena. Failure to make the connection between recurrent gastrointestinal bleeding and apparently unrelated symptoms attributable to pancreatitis may lead to a significant delay in diagnosis.- - - - - - - - - - ranking = 1.1555561202062keywords = haemorrhage (Clic here for more details about this article) |
10/177. Portal hypertension secondary to arterio-portal fistulae: two unusual cases.A 62-year-old male presented with variceal haemorrhage. Investigation demonstrated a fistula between the left gastric artery and portal vein with a porto-systemic gradient of 35 mm Hg. Variceal bleeding was controlled by a transcatheter embolisation of the fistula, but the patient died of septicaemia three weeks later. The second patient, a 42-year-old male who presented with variceal bleeding was shown to have diffuse arterio-venous fistulae involving the right lobe of the liver with a portosystemic gradient of 25 mm Hg. In this case the variceal bleeding was successfully controlled by insertion of a transjugular intrahepatic portosystemic shunt (TIPS). The pathogenesis of portal hypertension in arterioportal fistulae and the role of interventional radiological techniques in the management of variceal bleeding in these patients is discussed.- - - - - - - - - - ranking = 1.1555561202062keywords = haemorrhage (Clic here for more details about this article) |
