11/20. Spinal cord infarction. Report of 8 cases and review of the literature.While the incidence of spinal cord ischemia is not known, it is generally considered to be rare. diagnosis of presumed spinal cord ischemia requires the appropriate clinical picture and exclusion of other possible etiologies. Definitive diagnosis usually requires postmortem examination. During a 52-month period, 8 patients with presumed spinal cord infarction were evaluated at a 238-bed community hospital. These cases accounted for 1.2% of all admissions for stroke. infarction of the spinal cord was confirmed on postmortem examination in 2 cases. All 6 surviving patients regained substantial motor function. Bowel and/or bladder dysfunction returned to normal in 3 patients. The literature is reviewed, and the cases are discussed in relation to the pertinent anatomic, pathogenic, and clinical aspects of spinal cord infarction.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
12/20. Multiple cholesterol emboli syndrome. Bowel infarction after retrograde angiography.The two patients described in this article are among the first to have been diagnosed with extensive bowel infarction as a result of cholesterol embolization following cardiac catheterization. The presence of acute hypertension, renal insufficiency, livedo reticularis, and gangrenous skin changes are characteristic manifestations of the multiple cholesterol emboli syndrome. Additionally, gastrointestinal symptoms and melena may herald ischemia and infarction of the alimentary tract. Anticoagulation and thrombolytic therapy are relatively contraindicated in this syndrome and may, in fact, be a precipitating cause. The prognosis is usually poor; however, survival is possible with aggressive medical and surgical therapy, despite extensive infarction of the gastrointestinal tract and other organs. Prevention remains the most critical aspect of management of this potentially catastrophic illness.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
13/20. Polar infarct in a transplanted kidney: cause of a pseudomass.ultrasonography has become fairly standard for assessing common complications of renal transplantation such as hydronephrosis, urinomas, and lymphoceles. Infarctions are a less common complication that may occur in the setting of transplant rejection. We report a case in which an apparent solid mass on sonography proved to represent normal residual renal parenchyma in a kidney with a small shrunken lower pole due to infarction.- - - - - - - - - - ranking = 1.9570224083296keywords = standard (Clic here for more details about this article) |
14/20. Closed interlocking nailing of the femur complicated by an intramedullary calcified lesion.The interlocking intramedullary nail has greatly expanded the indications for closed intramedullary nailing of the femur. We describe a complication caused by the presence of a calcified lesion located at the proximal metaphyseal-diaphyseal junction of the femur. This lesion could not be penetrated by hand reamers. We used a long 3.5-mm drill bit to place a hole in the infarct, which then allowed passage of the hand reamer. The operation then proceeded in the standard fashion without complications.- - - - - - - - - - ranking = 1.9570224083296keywords = standard (Clic here for more details about this article) |
15/20. Degeneration of the corticospinal tract following portosystemic shunt associated with spinal cord infarction.The clinicopathological aspects of a case of myelopathy that followed the creation of a surgical porto-caval shunt for hepatic cirrhosis and oesophageal varices are presented. Degeneration of the lateral corticospinal tracts associated with diffuse bilateral ischaemic changes of the spinal gray matter and proliferation of Alzheimer type 2 glia in the brain and brain stem were the most prominent findings. The association of corticospinal tract degeneration and ischaemic lesions of spinal gray matter in absence of any anatomical cause of spinal cord infarction suggests that a modification of the spinal blood flow caused by creation of portosystemic shunts might be the basic pathogenetic mechanism of this complication of severe liver disease.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
16/20. Neonatal appendicitis: ischemic infarction in incarcerated inguinal hernia.A premature 12-day-old infant with ischemic infarction of the appendix due to hernial incarceration is presented. literature review (1901-1975) of 106 cases of acute appendicitis in the first 30 days of life permitted tabulation of some clinical aspects in 94 cases. Overt manifestations mandating surgical intervention and isolation of the inflammatory process in the inguinoscrotal region are important factors responsible for the significantly better prognosis for neonatal hernial versus intraabdominal appendicitis.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
17/20. Orbital infarction syndrome after surgery for intracranial aneurysms.BACKGROUND: Global orbital infarction results from ischemia of the intraocular and intraorbital structures due to hypoperfusion of the ophthalmic artery and its branches. patients: The authors describe six patients in whom acute proptosis, ophthalmoplegia, and blindness developed immediately after surgery for intracranial aneurysms. RESULTS: All patients underwent standard frontotemporal craniotomies to clip their aneurysms. In all patients, proptosis, ophthalmoplegia, and blindness developed in the immediate postoperative period; fundus abnormalities included retinal edema, retinal arteriolar narrowing and other vascular abnormalities, and pale optic disc swelling. Some patients had facial and corneal anesthesia. ophthalmoplegia and facial anesthesia improved in most patients, but none regained any vision in the affected eye. CONCLUSION: Orbital infarction syndrome is a rare complication of neurosurgical procedures. Increased orbital pressure probably reduced ophthalmic artery and collateral arterial perfusion, resulting in ischemia of the intraocular and intraorbital structures. There may be multiple factors that compound the risk for orbital infarction, and patients with subarachnoid hemorrhage, increased intracranial pressure, anomalous arterial or venous circulation, or impaired orbital venous outflow seem particularly vulnerable.- - - - - - - - - - ranking = 1.9570224083296keywords = standard (Clic here for more details about this article) |
18/20. Anterior spinal artery infarction.spinal cord ischemia, as represented by acute paraplegia, is rare in the absence of trauma. It is even more uncommon that an infarction of the spinal cord occurs in a patient with no predisposition to vascular disease. We report a case of anterior spinal artery syndrome resulting from an infarction of the anterior aspect of the spinal cord in an otherwise healthy 45-year-old woman.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
19/20. CT manifestations of infarcted epiploic appendages of the colon.Two patients presenting with acute onset of left lower abdominal pain due to infarcted epiploic appendages are the subject of this report. Computed tomography (CT) in both cases showed localized pericolic inflammatory changes corresponding to the location of infarcted epiploic appendages on the serosal aspect of the descending colon or sigmoid. The clinical and radiological findings of this entity are briefly described.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
20/20. Bilateral diabetic thigh muscle infarction.A 19-year-old woman with insulin-dependent diabetes mellitus developed pain and tenderness in the medial aspect of the left thigh and calf, followed 1 week later by similar symptoms in the right leg. technetium 99m pyrophosphate (PYP) radionuclide scans showed increased flow and uptake in the medial thigh muscles. magnetic resonance imaging (MRI) of the thigh showed increased signal on proton density and T2-weighted images in the medial and lateral thigh compartments. High-resolution B-mode ultrasound showed hyperechoic changes in the anteromedial thigh muscles, with loss of normal myofascial interfaces, and a mixed appearance, bilaterally. Two months later, after the symptoms had begun to resolve, the images had improved. This case documents bilateral diabetic thigh infarction identified by abnormal technetium 99m PYP flow studies, MRI signal, and B-mode ultrasound imaging.- - - - - - - - - - ranking = 1keywords = aspect (Clic here for more details about this article) |
