1/343. pituitary apoplexy after cardiac surgery presenting as deep coma with dilated pupils.Acute clinical deterioration due to infarction or haemorrhage of an existing, often previously unrecognized, pituitary tumour is a rare but well-described complication. It can occur spontaneously or may be caused e.g. by mechanical ventilation, infection or surgical procedures. We report on a case of pituitary apoplexy occurring in a 64-year-old patient 3 weeks after cardiac surgery. The patient presented with deep coma and dilated pupils. magnetic resonance imaging revealed a haemorrhagic pituitary tumour. After prompt endocrinologic replacement therapy with levothyroxine and hydrocortisone the patient regained consciousness. Neurological examination revealed right oculomotor nerve palsy and bilateral cranial nerve VI palsy. Subsequent trans-sphenoidal removal of a nonfunctional macroadenoma with large necrotic areas was performed. The patient recovered completely. To our knowledge, pituitary tumours presenting with a combination of deep coma and dilated pupils must be considered exceedingly rare. Possible pathophysiologic mechanisms are discussed. As our case illustrates, even in severe cases complete recovery is possible if the diagnosis is suspected, and diagnostic and therapeutic measures are initiated in time.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/343. Fatal late multiple emboli after endovascular treatment of abdominal aortic aneurysm. Case report.BACKGROUND: The short term experience of endovascular treatment of abdominal aortic aneurysms (AAA) seems promising but long term randomised data are lacking. Consequently, cases treated by endovascular procedures need to be closely followed for potential risks and benefits. CASE REPORT: A 70 year-old mildly hypertensive male without previous or present arteriosclerotic, pulmonary, or urological manifestations was subjected to endovascular treatment after his mass-screening diagnosed abdominal aortic aneurysm had expanded to above 5 cm in diameter, the aneurysm having been found by CT-scanning and arteriography to be endovascularly treatable. A Vanguard bifurcated aortic stent graft was implanted under epidural/spinal anaesthesia and covered by cephalosporine and heparin (8000 IE) protection. Apart from treatment of a groin haematoma and stenosis of the left superficial femoral artery, the postoperative period presented no problems. A few days before the monthly follow-up visit, the patient developed uraemia, gangrene of one foot and dyspnoea. blood glucose and LDH was elevated. Deterioration led to death a month and a half after stent implantation. autopsy showed extraordinary large, extensive soft, brown vegetations in the lower part of the thoracic aorta above the properly infrarenally-placed stent. Microscopic examination revealed multiple microemboli in the liver, spleen, pancreas, intestines, testes, and especially the kidneys. DISCUSSION: Early death from microemboli after aortic stent implantation has been reported. However, the present case developed fatal multiple microemboli so late that they could not have originated from the excluded mural thrombus. The sudden death of an otherwise healthy man of extensive microemboli is difficult to explain. The stent application may have altered the proximal flow and wall movements disposing to microemboli in the case of vegetations.- - - - - - - - - - ranking = 3.5927197917635keywords = haematoma (Clic here for more details about this article) |
3/343. Chronic subdural haematoma following caesarean section under spinal anaesthesia.Intracranial subdural haematoma is a rare complication of spinal anaesthesia. This report describes the case of a 31-year-old woman who presented with post partum headache following spinal anaesthesia for caesarean section. Bilateral haematomata were evacuated via burr-holes performed under total intravenous anaesthesia and the patient made a complete and uneventful recovery. The recognized causes of subdural haematoma are discussed.- - - - - - - - - - ranking = 107.8319171233keywords = subdural, subdural haematoma, haematoma (Clic here for more details about this article) |
4/343. 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 = 3keywords = haemorrhage (Clic here for more details about this article) |
5/343. Neuro-ophthalmic complication after maxillary surgery.We report an unusual case of ophthalmoplegia after maxillofacial surgery. A thirteen year old girl with unilateral left cleft lip and palate underwent maxillary advancement by distraction osteogenesis. Postoperatively she developed diplopia. The diplopia was not due to orbital lesions, most often seen after maxillofacial surgery, but to a haemorrhage posterior to the cavernous sinus.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
6/343. Lumbar spinal subdural hematoma following craniotomy--case report.A 52-year-old female complained of lumbago and weakness in the lower extremities 6 days after craniotomy for clipping an aneurysm. Neurological examination revealed symptoms consistent with lumbosacral cauda equina compression. The symptoms affecting the lower extremities spontaneously disappeared within 3 days. Magnetic resonance (MR) imaging 10 days after the operation demonstrated a lumbar spinal subdural hematoma (SSH). She had no risk factor for bleeding at this site, the symptoms appeared after she began to walk, and MR imaging suggested the SSH was subacute. Therefore, the SSH was probably due to downward movement of blood from the cranial subdural space under the influence of gravity. SSH as a complication of cranial surgery is rare, but should be considered if a patient develops symptoms consistent with a lumbar SSH after craniotomy.- - - - - - - - - - ranking = 47.087377901606keywords = subdural (Clic here for more details about this article) |
7/343. Postbulbar duodenal ulcer.Postbulbar duodenal ulceration is not common, but when present is difficult to diagnose and treat. Between January 1965 and September 1971, 1,080 patients with duodenal ulcers were treated surgically at St James Hospital. Forty-one ulcers were found at operation to lie distal to the duodenal bulb. pain was the most common indication for surgery. In six-patients it was clinically indistinguishable from biliary pain, giving rise to diagnostic difficulty. Twelve patients (29%) presented with haemorrhage, a percentage similar to the 25% of bulbar ulcers presenting with this complication over the period of this study. This is contrary to the finding in most other series, that postbulbar ulceration is more frequently complicated by haemorrhage than is bulbar ulceration. Perforation and stenosis are uncommon complications. Postbulbar ulceration is easily overlooked in conventional barium studies. Only one-third of the patients subjected to barium meal x-ray examination had their ulcers identified in the first study. In a further third the presence of an ulcer was suspected, and the remainder required multiple investigations for undiagnosed symptoms before the condition was demonstrated. duodenoscopy was not performed in a sufficient number of patients for its value to be assessed, but other reports indicate that it should be a valuable manoeuvre. The technical difficulties and potential hazards of Polya gastrectomy are discussed and special reference is made to the surgical management of bleeding postbulbar ulcers.- - - - - - - - - - ranking = 2keywords = haemorrhage (Clic here for more details about this article) |
8/343. Symptomatic calcified subdural hematomas.Two unique cases of chronic calcified subdural hematomas are reported in children as a long-term complication of a ventriculoperitoneal shunt. Both the patients had undergone shunt procedures in infancy for congenital hydrocephalus. In one patient, the cause of the hydrocephalus was aqueduct stenosis, while in the second patient, a lumbar meningomyelocele was associated with hydrocephalus. In both these patients, a ventriculoperitoneal shunt was done in infancy. In one of them, following the shunt surgery, a bilateral subdural collection was noticed which required burr hole evacuation. Both the patients remained asymptomatic for 9 years, when they presented to our center with acute raised intracranial pressure and contralateral hemiparesis. Both the patients had a relatively short history and had altered sensorium at admission. Surprisingly, in both the patients, the CT scan showed significant mass effect producing calcified subdural hematomas. The shunt systems were found to be working well at surgery. craniotomy and excision of the calcified subdural hematomas was undertaken. Postoperatively, the patients showed satisfactory recovery, and at discharge the patients were doing well. At the follow-up at the outpatient clinic, the patients were asymptomatic.- - - - - - - - - - ranking = 62.783170535475keywords = subdural (Clic here for more details about this article) |
9/343. Haematemesis and Melaena: surgical management.A prospective study of the surgical management of 100 consecutive patients with benign, non-variceal upper gastrointestinal bleeding is presented. The manner of presentation, precipitating factors, investigations and associated medical problems are discussed. Chronic duodenal ulceration was the most common cause of haemorrhage. vagotomy and drainage with oversewing or excision of the bleeding ulcer was the surgical procedure performed in 71 of the patients in the series. The incidence of recurrent bleeding was 7%; no patient in this category required further operation. The mortality rate was 6%, and there were no deaths recorded in the patients who underwent vagotomy and drainage. The reasons for the relatively low surgical mortality are discussed.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
10/343. Arachnoid cyst rupture with concurrent subdural hygroma.arachnoid cysts (ACs) are relatively common intracranial mass lesions, which occur most often in the middle cranial fossa. While these lesions can present as a mass lesion, many are asymptomatic. Rarely, posttraumatic or spontaneous rupture of ACs can result in intracystic hemorrhage, subdural hematoma or subdural hygroma. We have encountered two cases of ruptured arachnoid cysts that resulted in subdural hygromas. Both patients harbored middle cranial fossa cysts and suffered mild closed head injuries. The presentation, radiographic findings and surgical management of these patients as well as the association between ACs and subdural hygromas are described.- - - - - - - - - - ranking = 62.783170535475keywords = subdural (Clic here for more details about this article) |
