1/470. Disorders in cerebellar ocular motor control. II. Macrosaccadic oscillation. An oculographic, control system and clinico-anatomical analysis.A distinctive cerebellar ocular motor disorder, macrosaccadic oscillation, evolved simultaneously with an acute cerebellar syndrome in 4 patients, 2 with haemorrhagic metastatic melanoma deep in the vermis, a third with a presumed cerebellar haematoma and a fourth with focal demyelinating disease. Ocular oscillations were conjugate, horizontal, symmetrical, occurred in bursts of several seconds duration, had amplitudes of 30 degrees to 50 degrees, and were evoked whenever the patient attempted to shift visual fixation or pursue a moving target. Photo-electric recordings in one patient with tumour defined features of this disorder of saccadic eye movement: (i) oscillation was composed of saccades, (ii) frequency was 2 Hz, (iii) bursts occurred with amplitude first increasing and then decreasing, (iv) intervals between beginnings of saccades averaged 260 ms and (v) eye position did not exhibit systematic drift during the intersaccadic period. These features documented the inreased gain and instability of the visually guided saccadic system. By using increased feed-forward gain in a sampled-data control model we simulated the pattern of macrosaccadic oscillation. We belive that the acute loss of the calibrator function of the cerebellum accounts for the gain abnormality underlying macrosaccadic oscillation.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
2/470. Dissecting intramural haematoma of the oesophagus.The largest series of patients (n = 10) with dissecting intramural haematoma of the oesophagus is described. The typical features, chest pain with odynophagia or dysphagia and minor haematemesis are usually present but not always elicited at presentation. If elicited, these symptoms should suggest the diagnosis and avoid mistaken attribution to a cardiac origin for the pain. precipitating factors such as a forced Valsalva manoeuvre cannot be identified in at least half the cases. Early endoscopy is safe, and confirms the diagnosis when an haematoma within the oesophageal wall or the later appearances of a longitudinal ulcer are seen. Dissecting intramural haematoma of the oesophagus has an excellent prognosis when managed conservatively.- - - - - - - - - - ranking = 7keywords = haematoma (Clic here for more details about this article) |
3/470. Multiple postoperative intracerebral haematomas remote from the site of craniotomy.A postoperative haemorrhage is a common and serious complication of a neurosurgical procedure. It usually occurs at the site of the surgery, but on occasion a postoperative haematoma is found at a distance from the previous craniotomy. Multiple postoperative haemorrhages are extremely rare. We report the case of a 63-year-old woman, operated on for the removal of a supratentorial astrocytoma, who developed in the early post-operative period multiple bilateral intracerebral haematomas without involvement of the surgical bed.- - - - - - - - - - ranking = 6.0005428536887keywords = haematoma, haemorrhage (Clic here for more details about this article) |
4/470. A case of amnestic syndrome caused by a subcortical haematoma in the right occipital lobe.A case of an amnestic syndrome caused by a subcortical haematoma in the right occipital lobe is reported. A 62-year-old right-handed man presented with a sudden onset of headache to the hospital. On admission, he had a left homonymous hemianopsia, disorientation and recent memory disturbance, but had normal remote memory and digit span. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a subcortical haematoma in the right occipital lobe. These findings suggest that the patient's amnesia was caused by a lesion of the retrosplenial region in the non-dominant hemisphere.- - - - - - - - - - ranking = 6keywords = haematoma (Clic here for more details about this article) |

6/470. hematometra and extended vaginal haematoma after laser conization. A case report.A very rare case of haematometra and extended vaginal haematoma in a 53-year-old woman after laser conization is reported. The patient presented with amenorrhea and complete urinary retention. The possible pathogenesis of this complication is discussed. ultrasonography, combined with physical examination were very helpful in determining the diagnosis. Cervical dilation and protection of surrounding tissues from thermal damage is recommended during laser conization to avoid similar complications.- - - - - - - - - - ranking = 5keywords = haematoma (Clic here for more details about this article) |

Acute renal failure due to retroperitoneal haematoma: a question of warfarin dispensation.We report a case of an important and uncommon haemorrhagic complication in a patient receiving warfarin treatment. We reflect on the importance of close monitoring of anticoagulant therapy to prevent haemorrhagic complications and to ensure safety in longterm use.- - - - - - - - - - ranking = 4keywords = haematoma (Clic here for more details about this article) |
8/470. Extradural haematoma complicating lumbar puncture following a craniotomy. A case report.BACKGROUND: This case report illustrates the development of an intracranial extradural haematoma (EDH) as an uncommon complication of a lumbar puncture. CLINICAL PRESENTATION: A 10-year-old girl operated for intra-third ventricular cysticercosis developed postlumbar puncture headache after a drainage lumbar puncture (LP) on the 7th postoperative day. CT scan revealed a right frontal EDH away from the operative site. INTERVENTION: The child was managed conservatively in view of her preserved sensorium. RESULTS: The child had an uneventful recovery. Follow-up CT scans showed resolution of the haematoma. CONCLUSIONS: LP, though considered to be a safe procedure, may rarely be associated with a potentially lethal intracranial haematoma, which can be managed successfully if diagnosed at an early stage.- - - - - - - - - - ranking = 7keywords = haematoma (Clic here for more details about this article) |
9/470. 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 = 0.00010971738539996keywords = subdural (Clic here for more details about this article) |
10/470. life-threatening spontaneous psoas haematoma treated by transcatheter arterial embolization.We report two cases of large spontaneous psoas haematoma in patients on anticoagulant therapy. Active bleeding was well demonstrated on spiral CT. Transcatheter arterial embolization was used successfully to stop bleeding. The diagnostic strategy, the relevance of spiral computed tomography and our therapeutic approach to this complication are discussed.- - - - - - - - - - ranking = 5keywords = haematoma (Clic here for more details about this article) |
