1/90. Subdural empyema and blindness due to cavernous sinus thrombosis in acute frontal sinusitis.

    In this era of antibiotics, the complications of acute sinusitis are much less frequently encountered. Although orbital complications are most common, intracranial complications carry a high rate of mortality and morbidity. We describe a case of acute frontal sinusitis with subdural empyema and blindness due to cavernous sinus thrombosis and carotid artery thrombosis with a discussion of treatment of these complications and the etiology of blindness in sinusitis.

2/90. Rhinosino-orbital mucormycosis causing cavernous sinus thrombosis and internal carotid artery occlusion: radiological findings in a patient with treatment failure.

    The authors describe a case of rhinosino-orbital mucormycosis with cavernous sinus thrombosis in association with internal carotid artery occlusion diagnosed by use of computerized tomography (CT) and magnetic resonance imaging (MRI). Cranial CT is a useful imaging tool in the diagnosis of rhinosinal invasive fungal disease and MRI offers excellent aid in the detection of intracranial extension. early diagnosis and rapid institution of surgical debridement and antifungal therapy is the rule of thumb in treating this disorder. In our patient, surgically inaccessible bone lesion and involvement of the central nervous system are taken as major causes for his grave outcome. In addition, failure to advance appropriate amphotericin b dosage may also make the infectious process uncontrollable in this patient.

3/90. Internal carotid artery occlusion in a patient with malignant peritoneal mesothelioma: is it a sign of malignancy-related thrombosis?

    To our knowledge, the occlusion of arteries and platelet hyperaggregation have not been reported in patients with malignant mesothelioma. However, venous thromboembolism, especially in the pulmonary vasculature in association with thrombocytosis and hyperfibrinogenemia, are commonly noticed in this disorder. Furthermore, we detected enhanced platelet aggregation in a case of malignant peritoneal mesothelioma with internal carotid artery occlusion in whom there were postsplenectomy thrombocytosis and hyperfibrinogenemia. The possible mechanisms of ICA occlusion in this patient, including the role of MPM and postsplenectomy state, thrombocytosis, platelet functional changes, and other factors were investigated and discussed.

4/90. Delayed bilateral internal carotid artery thrombosis following accidental strangulation.

    A 24-yr-old male presented after a fishing accident in which he was pulled underwater by a rope attached to a crayfish pot. He was winched out of the water with the rope still around his neck, sustaining serious neck injuries that ultimately led to his death. After initial resuscitation, he remained fully conscious for approximately 8 h, after which there was a rapid and sudden deterioration in his level of consciousness. The presentation, investigation, management and subsequent postmortem findings are presented and discussed.

5/90. Thrombosis of the internal carotid artery secondary to soft palate injury in children and childhood. Report of two cases.

    Trauma to the soft palate is a uncommon event during childhood. stroke following intraoral trauma is also rare, but has been well documented by the current literature as a potentially serious complication. In this article, we report 2 cases of posttraumatic internal carotid artery thrombosis depicted by imaging studies. We discuss pathogenesis, and the literature is reviewed.

6/90. Fulminant cerebral infarction in a patient with nephrotic syndrome.

    Fulminant cerebral infarction secondary to arterial thrombosis in adults with nephrotic syndrome is rare. We report a 42 year old male with fulminant right anterior cerebral and middle cerebral artery infarction. Minimal change disease of the kidney was documented by renal biopsy. The possible pathogenesis is discussed and pertinent literature reviewed.

7/90. Endovascular repair of an extracranial internal carotid artery aneurysm complicated by heparin-induced thrombocytopenia and thrombosis.

    PURPOSE: To report the endovascular treatment of a symptomatic extracranial internal carotid artery (ICA) aneurysm that was complicated by heparin-induced thrombocytopenia and thrombosis. methods AND RESULTS: After undergoing a coronary artery bypass graft procedure, a patient was diagnosed with a symptomatic, 3.5-cm ICA aneurysm by computed tomography and angiography. Via a semiclosed access, an Enduring vascular graft was inserted under controlled back bleeding from the ICA. The patient was recovering uneventfully when routine duplex scanning on the fifth postoperative day suggested multiple thrombi within the graft, which was confirmed by arteriography. thrombectomy and local fibrinolysis were performed; however, the graft occluded the next day without causing neurological symptoms. heparin-induced thrombocytopenia was diagnosed by enzyme-linked immunosorbent assay. CONCLUSIONS: Endovascular repair of high cervical extracranial ICA aneurysms is feasible, and protection against intracerebral embolization can be achieved using a semiclosed technique with controlled back bleeding from the ICA during endograft deployment. However, multiple thrombi or thrombotic occlusion during the postoperative period, particularly in a patient already sensitized to heparin, should direct attention toward possible heparin-induced thrombocytopenia.

8/90. dacarbazine-induced carotid artery and deep venous thrombosis in a patient with leiomyosarcoma: case report.

    Thromboembolic events are a common and important cause of morbidity and mortality in cancer patients that require early diagnosis and treatment. Reports have suggested that chemotherapeutic agents may contribute to this risk. In this case report, a 60-year-old male patient on chemotherapy (dacarbazine and doxorubicin) for leiomyosarcoma with no previous history of thromboembolism developed left carotid artery thrombosis 3 days after the first cycle of chemotherapy. A low molecular weight heparin was started for a possible cerebrovascular accident-related thrombosis. In the second cycle, he developed right femoral vein thrombosis only 2 days after initiating the chemotherapy. The chemotherapy protocol was changed and the patient did not develop any thrombosis during the 1-year follow-up. In the literature, no thrombotic complications have previously been reported due to either dacarbazine or doxorubicin. In conclusion, elderly patients on chemotherapy should be carefully monitored for thromboembolic complications and, in case of thrombosis, the chemotherapy protocol should be changed.

9/90. Spontaneous thrombosis of intracavernous internal carotid artery aneurysm and parent artery occlusion in patients with positive balloon test occlusion--two case reports.

    Two patients with giant intracavernous internal carotid artery (ICA) aneurysms were intolerant to balloon test occlusion of the ICA, and later developed spontaneous thrombosis of the aneurysm and the parent ICA without ischemic sequelae. Case 1: A 60-year-old female with a giant right intracavernous ICA aneurysm presented with right abducens nerve paresis. An unsuccessful extracranial-to-intracranial bypass graft operation was complicated by transient postoperative ophthalmoplegia. The patient did not tolerate balloon test occlusion of the right ICA after attempted bypass surgery, and was treated conservatively. The patient presented with acute onset of headache 3 years later. Case 2: A 50-year-old female with a giant right intracavernous ICA aneurysm presented with right abducens nerve paresis. The patient was managed conservatively after a positive balloon test occlusion of the right ICA. The patient suffered transient hypopituitarism and acute onset of headache 2 years later. Spontaneous thrombosis of the aneurysms and occlusion of the parent ICA were found in both patients. Neither had major hemispheric infarcts, but the first patient had asymptomatic infarcts, which were presumed to be thromboembolic in nature. patients with intracavernous ICA aneurysms who have positive balloon test occlusions appear to develop tolerance to spontaneous and gradual occlusion of the ICA without significant sequelae. However, these patients have an increased risk of developing embolic infarctions. The role for anticoagulation and repeat hemodynamic tests remains unclear.

10/90. Temporary monocular blindness associated with acute carotid thrombosis: a case report.

    We report upon a patient with multiple, progressive episodes of temporary monocular blindness associated with acute thrombosis and a critical internal carotid artery stenosis. Carotid angiography demonstrated an anatomically compelling situation consisting of a critical reduction of flow distal to a preocclusive internal carotid artery stenosis accompanied by intraluminal thrombus. The patient was managed successfully by urgent thrombectomy and carotid endarterectomy. This case report highlights principles in management of patients with the unstable neurologic condition of temporary monocular blindness associated with an anatomically compelling situation demonstrated on angiography.
