1/115. Sight-threatening acute orbital swelling from peribulbar local anesthesia.Severe allergic reactions to peribulbar local anesthesia are extremely rare. A 70-year-old woman presented with acute orbital swelling and optic nerve dysfunction after a peribulbar local anesthetic injection. The patient was treated with acute orbital decompression as well as intravenous antibiotics and methylprednisolone; she made a good recovery. An allergy, probably to lignocaine, was the most likely cause. Urgent recognition and treatment of this condition may prevent potentially serious visual consequences.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
2/115. Unilateral iliac vein occlusion, caused by bladder enlargement, simulating deep venous thrombosis.A variety of conditions cause unilateral leg swelling and thus mimic deep venous thrombosis (DVT). A heretofore-underappreciated condition that may lead to unilateral iliac vein compression, simulating DVT, is massive enlargement of the bladder caused by urinary retention. A case that demonstrates this condition is described. Although this disorder has been reported only three times before, its occurrence should be recognized by clinicians in light of the overall aging of our society. In addition, this case highlights the need for careful and thorough evaluation of patients who have unilateral lower-extremity edema.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
3/115. Ultrasonographically guided injection of corticosteroids for the treatment of retroseptal capillary hemangiomas in infants.PURPOSE: Injection of corticosteroids is a well-documented and successful mode of treatment for periorbital capillary hemangiomas. Because of the greater potential risk involved with retrobulbar injections, no prior study has described this treatment for tumors located behind the orbital septum. Although retroseptal intraorbital capillary hemangiomas comprise only 7% of all adnexal capillary hemangiomas, complications such as optic nerve compression or astigmatism may necessitate treatment. methods: Three patients with deep orbital hemangiomas that caused vision-threatening complications were treated with intralesional injections of triamcinolone and betamethasone. Orbital injection was performed with use of real-time ultrasonographic guidance of the needle. This technique was valuable in providing continuous, accurate, and safe advancement of the needletip in the orbit to avoid the globe and orbital walls. ultrasonography also permitted precise placement of the needle tip within the tumor and visualization of the injected material. RESULTS: Significant improvement was demonstrated in all cases on the basis of both ultrasonographic measurements and regression of clinical manifestations such as astigmatism, chemosis, proptosis, and optic nerve pallor. No complications were noted. CONCLUSION: Intralesional injection of corticosteroids to treat retroseptal and retrobulbar capillary hemangiomas was found to be a safe and effective treatment modality in our patients. Positioning of the injecting needle was guided by ultrasonography.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
4/115. superior vena cava syndrome presenting as persistent erythematous oedema of the face.The superior vena cava syndrome occurs when extrinsic compression or intraluminal occlusion impedes blood flow through this vessel. Detecting the characteristic cutaneous features can lead to an early diagnosis of this condition. We report a 73-year-old patient with a 4-year-history of erythematous oedema of the face. The underlying cause was a large retrosternal goitre obstructing the superior vena cava. Subtotal thyroidectomy led to dramatic improvement of all dermatologic symptoms.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
5/115. Successful resuscitation during fetal surgery.After in utero resection of a sacrococcygeal teratoma coupled with a transfusion of packed red blood cells, a 23-week-gestation fetus had bradycardia. Chest compressions were begun and epinephrine, atropine, and sodium bicarbonate were given, while the fetus remained bathed in warm saline. After 3 rounds of drugs, and just before withdrawing support, the fetal heart resumed beating and normal cardiac function. Based on to this case, the authors developed a resuscitation protocol for fetal surgery.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
6/115. Abdominal compartment syndrome with massive lower-extremity edema caused by colonic obstruction and distention.Abdominal compartment syndrome is a well-described condition in which increased intra-abdominal pressure causes various physiologic derangements with adverse effects on cardiac, pulmonary, and renal function. A patient presented with radiation-induced distal colonic obstruction, abdominal distention, and severe bilateral leg edema. We performed a diverting transverse loop colostomy as treatment for her obstruction. This resulted in massive, spontaneous diuresis with complete resolution of her lower-limb edema. Abdominal compartment syndrome due to colonic obstruction can contribute to the development of lower-extremity edema. colon decompression with reduction of intra-abdominal pressure can lead to resolution of edema in this situation.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
7/115. A clinical report about an unusual occurrence of post-anesthetic tongue swelling.dentures are routinely removed from the oral cavity before general anesthetic procedures. They are only reinserted much later when the patient returns to the room. This clinical report describes an edentulous patient who developed acute tongue swelling from venous congestion as a result of tongue recovery from general anesthesia. Her complete dentures were used to separate the residual ridges during the recovery period and relieved the congestion. Denture insertion increased the height and volume of the oral cavity, which reduced pressure on the tongue, preventing a cycle of tongue compression, congestion, and swelling. This unusual complication suggests that it may be prudent for the edentulous patient to be accompanied by their dentures in the perioperative period.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
8/115. Upside-down orbitopathy: unilateral orbital dependent-tissue oedema causing total visual loss.The case is reported of a 24-year-old man who was involved in a road traffic accident and became trapped upside down with the right side of his face being the most dependent part of his body. Marked hemifacial tissue oedema was associated with right acute compressive orbitopathy and vascular compromise. Acute dysfunction of al orbital nerves was found on examination. Such neuropathy is usually related to the consequences of direct trauma, fractures or haemorrhage; however, computed tomography scanning demonstrated no evidence of orbital fracture or haemorrhage. Immediate anterior surgical orbital decompression was performed in the emergency room in addition to high dose intravenous steroids. Dependent orbtal tissue oedema is proposed as a mechanism of compressive orbitopathy with consequent ischaemic damage to all orbital nerves, total visual loss and complete ophthalmoparesis. Good recovery of other orbital nerves has occurred and the globe has reperfused. Despite intervention, no visual function has returned.- - - - - - - - - - ranking = 1.443758410086keywords = compression, fracture (Clic here for more details about this article) |
9/115. Peduncular hallucinations associated with large posterior fossa meningiomas.Peduncular hallucinosis may be observed in patients with thalamic or brain stem ischemia or hemorrhage, while it has been less often described in association with brain stem or cerebellar tumors. We report in this paper two cases associated with large posterior fossa meningiomas. In the first patient hallucinosis appeared preoperatively as a result of brain stem compression and ceased after the tumor removal. In the second patient hallucinosis occurred after the surgery, as a result of surgical trauma with local brain stem edema, and ceased 4 days after treatment with desamethasone and carbamazepine.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
10/115. Orbital involvement in sickle cell disease: a report of five cases and review literature.PURPOSE: To present five cases of orbital infarction in sickle cell disease and review relevant literature. METHOD: We reviewed the hospital records of 5 patients with sickle cell disease who developed a periorbital swelling during a vaso-occlusive crisis and were managed at our hospital between April 1992 and June 2000. RESULTS: The 5 patients (4 with homozygous sickle cell disease and 1 with sickle cell-beta-thalassaemia disease) were aged 6-15 years with a history of multiple admissions for vaso-occlusive crises. The periorbital swelling spread to the orbit in 4 cases and resulted in proptosis (2 cases), restriction of ocular motility and visual impairment. In all 4 cases, computed tomography and/or magnetic resonance imaging of the orbits showed a mass adjacent to the orbital wall. In 2 cases the mass was identified as a haematoma. Orbital wall infarction was demonstrated in 3 cases by bone/bone marrow scintigraphy. Epidural haematomas were detected by computed tomography in one case. All patients received intravenous fluids, analgesics, broad spectrum antibiotics and steroids, as well as simple or exchange transfusion, and responded well to medical management. CONCLUSIONS: infarction of orbital bones during vaso-occlusive crises in sickle cell disease presents acutely with a rapidly progressive periorbital swelling. Haematomas frequently complicate the condition and, along with the inflammatory swelling, may lead to orbital compression syndrome. The condition is therefore sight-threatening, and necessitates prompt diagnosis and appropriate management for resolution without adverse sequelae. Imaging techniques are invaluable in the evaluation of patients. The majority of cases resolve with conservative treatment that includes steps to combat the vaso-occlusive crisis and use of systemic steroids under antibiotic cover.- - - - - - - - - - ranking = 1keywords = compression (Clic here for more details about this article) |
