1/585. Acute leukemia with the phenotype of a natural killer/T cell bipotential precursor.

    An acute leukemia with an unusual immunophenotype developed in a 17-year-old girl. At the initial presentation, extramedullary involvement was not evident, but with advancing disease, massive splenomegaly and an osteolytic rib tumor developed. The disease was aggressive and refractory to intensive chemotherapeutic regimens for myeloid and lymphoid malignancies, and the patient died 3 months after the initial presentation. The leukemic cells were of irregular shape and variable size; they had deeply indented or bi-lobed nuclei and relatively fine, azurophilic granules in their cytoplasm. They were positive for acid phosphatase and beta-glucuronidase in granular staining, but they were negative for myeloperoxidase. The leukemic cells had a unique immunophenotype: it was positive for T-cell antigens (CD1a, CD2, cytoplasmic CD3, CD4), myeloid antigens (CD13 and CD33), NK-cell antigen (CD56), CD19 and CD30. dna analysis revealed no gene rearrangement in the T-cell receptor beta, gamma and delta, or immunoglobulin heavy chain genes. The leukemic cells of our patient are thought to have arisen from the transformation of a putative precursor cell common to both the T- and NK-cell lineage in the bone marrow. The current literature on precursor NK-cell malignancy is reviewed, and its clinicopathological feature is discussed.

2/585. Endovascular stenting of an acutely thrombosed basilar artery: technical case report and review of the literature.

    OBJECTIVE AND IMPORTANCE: The goal of this report was to describe the successful percutaneous endovascular use of a Gianturco-Roubin-2 coronary stent in the treatment of an acute atherothrombotic occlusion of the basilar artery. To our knowledge, the percutaneous endovascular deployment of an intra-arterial stent for the treatment of an acute atherothrombotic occlusion of the basilar artery and the percutaneous endovascular placement of a Gianturco-Roubin-2 stent in the basilar artery have not been previously reported. CLINICAL PRESENTATION: An 83-year-old man presented with a recurrent, transient, locked-in syndrome resulting from a lower basilar artery occlusion caused by vertebrobasilar thrombosis superimposed on severe proximal basilar artery atheromatous stenosis. INTERVENTION: After successful superselective intra-arterial thrombolysis of the vertebrobasilar clot, balloon angioplasty of the underlying basilar artery stenosis was performed, without significant angiographic improvement. Percutaneous endovascular deployment of a Gianturco-Roubin-2 coronary stent of 4-mm diameter was subsequently performed, with excellent angiographic results. CONCLUSION: The patient made a very good neurological recovery but unfortunately died as a result of cardiogenic shock and sepsis. Detailed neuropathological follow-up results are presented; stent patency was revealed in the postmortem examination. The anatomic and pathophysiological considerations of basilar artery stent placement for the treatment of acute basilar artery occlusion related to atherosclerotic stenosis are discussed.

3/585. Purtscher's retinopathy in acute pancreatitis.

    A patient who became blind following an episode of alcohol-induced pancreatitis is described. The clinical appearance of this patient's retinal changes corresponds most closely to post-traumatic (Purtscher's) retinopathy. The etiology of the retinopathy is best explained by retinal vascular occlusion due either to fat embolism or thrombosis.

4/585. 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.

5/585. Acute upper limb ischemia: a complication of coronary artery bypass grafting.

    We present the case of a patient with acute upper limb ischemia after radial artery harvest for coronary artery bypass grafting. This occurred despite adequate preoperative and intraoperative assessment with the Allen test, hand-held Doppler and radial artery backbleeding. A successful outcome was achieved by performing brachioradial bypass grafting using reversed cephalic vein.

6/585. Rapid thrombectomy of superior sagittal sinus and transverse sinus thrombosis with a rheolytic catheter device.

    Thrombosis of the dural venous sinuses is a potentially lethal condition that remains a diagnostic dilemma. Clinical outcome is typically dependent on the timeliness of diagnosis and definitive treatment. We report a case of successful rapid thrombectomy of extensive thrombus within the superior sagittal and transverse sinuses using a rheolytic catheter device. This appears to be a promising treatment option, particularly in those patients who do not respond to other, more established, forms of therapy.

7/585. Acute neoplastic arterial embolism after pneumonectomy.

    Intra-arterial tumour embolism after pneumonectomy is a known but rare complication. It arises because of tumour involvement of pulmonary veins. Usual outcome of this complication is grave when embolism is to a major vessel. If embolism occurs in a peripheral circulation, timely intervention can avoid significant morbidity. We report a case where embolisation occurred in both the femoral arteries. Emergency embolectomy was done successfully avoiding major complication.

8/585. Acute pancreatitis and deep vein thrombosis associated with hellp syndrome.

    The hellp syndrome (HS) belongs to the list of obstetric complications believed to be associated with coagulation disorders. It was formerly thought that chronic intravascular clotting (DIC) in the placental vessels was the main cause. A hypercoagulable state has been reported in cases of severe HS associated with microvascular abnormalities that may involve cerebral, placental, hepatic and renal vessels. A case of acute pancreatitis and DVT of inferior cava in a pregnant woman, presenting with HS at 29 weeks, who was found to have a R506Q mutation, is reported. Preeclampsia-associated pancreatitis and DVT have rarely been reported. It is hypothesized that APC-R and factor v Leiden mutation may prove to be new and more important markers capable of predicting a more significant maternal morbidity associated with HS. Thrombosis prophylaxis may be considered during pregnancy in order to reduce hazardous multiorgan failure (MOF) in women who are heterozygous for factor v Leiden mutation.

9/585. lemierre syndrome and acute mastoiditis.

    lemierre syndrome seldom follows an episode of pharyngotonsillitis. Characteristically, it is comprised of septic thrombosis of the internal jugular vein and bacteremia, leading to lung emboli and metastatic abscess formation. We describe lemierre syndrome that complicates an acute mastoiditis, with considerations regarding its pathogenesis and management. Despite its sporadic occurrence, awareness of lemierre syndrome is important, since early recognition reduces both the morbidity and mortality associated with it.

10/585. Scintiangiographic diagnosis of acute mesenteric venous thrombosis.

    Scintiangiographic findings of prolonged mesenteric activity in a case of acute mesenteric thrombosis is described and 105 cases with abdominal scintiangiography are reviewed. Usual peak mesenteric blush occurred 5--15 sec after initial visualization of the aorta. Normal clearance of this activity was 15--30 sec. Future cases should confirm the importance of this observation in early diagnosis of mesenteric venous thrombosis.
