1/105. Primary percutaneous transluminal coronary angioplasty performed for acute myocardial infarction in a patient with idiopathic thrombocytopenic purpura.A 72-year-old female with idiopathic thrombocytopenic purpura (ITP) complained of severe chest pain. electrocardiography showed ST-segment depression and negative T wave in I, aVL and V4-6. Following a diagnosis of acute myocardial infarction (AMI), urgent coronary angiography revealed 99% organic stenosis with delayed flow in the proximal segment and 50% in the middle segment of the left anterior descending artery (LAD). Subsequently, percutaneous transluminal coronary angioplasty (PTCA) for the stenosis in the proximal LAD was performed. In the coronary care unit, her blood pressure dropped. Hematomas around the puncture sites were observed and the platelet count was 28,000/mm3. After transfusion, electrocardiography revealed ST-segment elevation in I, aVL and V1-6. Urgent recatheterization disclosed total occlusion in the middle segment of the LAD. Subsequently, PTCA was performed successfully. Then, intravenous immunoglobulin increased the platelet count and the bleeding tendency disappeared. A case of AMI with ITP is rare. The present case suggests that primary PTCA can be a useful therapeutic strategy, but careful attention must be paid to hemostasis and to managing the platelet count.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/105. Endocapsular hematoma: report of a case following glaucoma surgery in a pseudophakic eye.The authors describe a case of an endocapsular hematoma that occurred in a 69-year-old pseudophakic diabetic male following mitomycin C (MMC) augmented trabeculectomy for neovascular glaucoma (NVG). The clinical course of the patient is described, and the unique features of this case are presented and discussed. The endocapsular hematoma absorbed in 6 weeks with conservative management. The patient regained the preoperative visual acuity of 20/30, and his intraocular pressure was controlled without any glaucoma medication. The iris neovascularization regressed. This case is the first report of an endocapsular hematoma following glaucoma filtering surgery in a pseudophakic eye with neovascular glaucoma.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
3/105. life-threatening subcutaneous hematoma caused by an axillary pad in an anticoagulated patient.A large subcutaneous hematoma extending from the left axillary region to the left flank developed in a 70-year-old man receiving anticoagulant therapy. The cause was repeated microtrauma caused by the axillary pad on a walker. physicians and physiotherapists should be aware that rehabilitation devices causing pressure on the skin increase hemorrhagic risk in patients taking anticoagulants. Accordingly, these patients should systematically be checked for hemorrhagic complications, and the use of such devices should be limited.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
4/105. Drug-induced and traumatic nail problems in the haemophilias.Many persons with haemophilia suffer from hiv and receive highly active antiretroviral therapy. Three patients received indinavir and required surgery due to ingrown toenails. Two patients suffered from a traumatic subungual haematoma. The treatment protocol is described whereby the pressure exerted onto the germinal layer and the nail bed is relieved in order to alleviate pain and nail matrix damage.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/105. Stress-related primary intracerebral hemorrhage: autopsy clues to underlying mechanism.BACKGROUND: research into the causes of small-vessel stroke has been hindered by technical constraints. Cases of intracerebral hemorrhage occurring in unusual clinical contexts suggest a causal role for sudden increases in blood pressure and/or cerebral blood flow. CASE DESCRIPTION: We describe a fatal primary thalamic/brain stem hemorrhage occurring in the context of sudden emotional upset. At autopsy, the brain harbored several perforating artery fibrinoid lesions adjacent to and remote from the hematoma as well as old lacunar infarcts and healed destructive small-vessel lesions. CONCLUSIONS: We postulate that the emotional upset caused a sudden rise in blood pressure/cerebral blood flow, mediating small-vessel fibrinoid necrosis and rupture. This or a related mechanism may underlie many small-vessel strokes.- - - - - - - - - - ranking = 2keywords = pressure (Clic here for more details about this article) |
6/105. Posterior-fossa haemorrhage after supratentorial surgery--report of three cases and review of the literature.We present clinical details of three patients with posterior fossa haemorrhage after supratentorial surgery and discuss possible pathomechanisms of this rare complication. All patients were males of advanced age. Two patients presented with a history of hypertension. In all patients the occurrence of haemorrhage was associated with loss/removal of large amounts of cerebrospinal fluid (CSF) either intra-operatively (one patient undergoing aneurysm surgery) or postoperatively (all three patients: drainage of subdural hygromas or chronic subdural haematomas in two, external ventricular drainage in one patient). Treatment consisted in haematoma evacuation and/or external ventricular drainage. Two patients died, one patient recovered completely. Although haematomas distant from a craniotomy site are a well known entity, a review of the literature identified only 25 published cases of posterior fossa haemorrhage after supratentorial procedures in the CT era. Most often disturbances of coagulation, positioning of the patient and episodes of hypertension have been associated with this complication. Only one author described the occurrence of a haemorrhage after drainage of a supratentorial hygroma. We suggest that the loss of large amounts of CSF intra-operatively and post-operatively may lead to parenchymal shifts or a critical increase of transmural venous pressure with subsequent vascular disruption and haemorrhage.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
7/105. enoxaparin associated with hugh abdominal wall hematomas: a report of two cases.enoxaparin is a low-molecular-weight heparin used for prophylaxis against deep venous thrombosis. Indications include hip and knee replacement surgery, risk of deep venous thrombosis during abdominal surgery, and prevention of ischemic complications of unstable angina and non-Q-wave myocardial infarction. Its efficacy in the prevention of the above complications has been previously studied; however, the liberal use of enoxaparin is not without incident. Complications of enoxaparin include hemorrhage, thrombocytopenia, and local reactions. Since 1993 there have been more than 40 reports of epidural or spinal hematoma formation with the concurrent use of enoxaparin and spinal/epidural anesthesia or spinal puncture. Herein reported are two cases of abdominal wall hematomas in patients receiving prophylaxis with enoxaparin. Both patients sustained an unexplained fall in the hematocrit and abdominal pain. A CT scan confirmed the diagnosis. One patient recovered uneventfully; however, the other patient, on chronic hemodialysis, became hemodynamically unstable and hyperkalemic and sustained a fatal cardiac arrhythmia. An extensive review of the literature revealed no similar cases of abdominal wall hematomas associated with enoxaparin although other complications, including spinal and epidural hematomas, psoas hematomas, and skin necrosis have been reported. The extended use of enoxaparin as an anticoagulant requires the physician to be vigilant of these rare complications. Bleeding can occur at any site during therapy with enoxaparin. An unexplained fall in the hematocrit or blood pressure should lead to a search for a bleeding site.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
8/105. Traumatic subependymal hematoma during endoscopic third ventriculostomy in a patient with a third ventricle tumor: case report.Endoscopic third ventriculostomy has become a routine intervention for the treatment of non-communicating hydrocephalus. This technique is largely considered safe and a very low incidence of complications is reported. However, hemorrhage in the course of neuroendoscopy is still a problem difficult to manage. The authors present a case in which endoscopic third ventriculostomy and tumor biopsy were performed in a young patient with a huge tumor growing in the posterior part of the third ventricle. The surgical approach to realize the stoma was difficult because the tumor size reduced the third ventricle diameter. Surgical manipulation produced a traumatic subependymal hematoma. This hematoma drained spontaneously after few minutes into the ventricle and the blood was washed away. The postoperative neurological course was uneventful and the ventriculostomy showed to work well by reducing the size of the lateral ventricles and the intracranial pressure in three days. This complication during endoscopic third ventriculostomy has never been reported before. We emphasize the difficulty of endoscopic procedures in patients with huge tumors in the third ventricle. Where reduction in size of the third ventricle and of the foramen of Monro ist present we suggest a careful approach to the third ventricle.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
9/105. paraplegia caused by painless acute aortic dissection.OBJECTIVES: Painless acute aortic dissection in which paraplegia is the only presenting sign is rare, with limited reported cases. CASE REPORT: The authors report a patient with painless acute aortic dissection who presented with sudden onset paraplegia. Ischemic diseases of the spinal cord were suspected as the cause. MRI revealed extensive acute aortic dissection with an intramural hematoma. The patient was treated conservatively by strictly controlling his blood pressure. The treatment was successful, although the motor function of the lower extremities could not be rescued. Although 3% to 5% of patients with acute aortic dissection present with paraplegia as a result of spinal cord infarction, most of these patients experience severe pain prior to presentation. CONCLUSION: Painless acute aortic dissection in which paraplegia is the only presenting sign is very rare. However, aortic diseases, including acute aortic dissection, should always be considered as a differential diagnosis of patients with sudden onset, painless paraplegia.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
10/105. Physical restraint and subcutaneous hematoma in an anticoagulated patient.A large subcutaneous hematoma extending from the breastbone region to the left axillary region and left flank developed in a 86-year-old anticoagulated man because of repeated microtrauma from a physical restraint used to prevent his rising from a chair. physicians, nurses, and physiotherapists should recognize that physical restraints causing pressure on the skin increase hemorrhagic risk in patients who take low molecular weight heparin. Accordingly, they should systematically check for hemorrhagic complications and attempt to limit the use of such devices.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
