1/456. A successful case of pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension with a thrombus in the right ventricle.

    Chronic thromboembolism is a frequent cause of progressive hypertension and carries a poor prognosis. Medical treatment is not effective and surgery provides the only potential for a cure at present. We herein report a successful case of thromboendarterectomy treated via a median sternotomy with intermittent circulatory arrest. A 43-year-old man was admitted to our hospital complaining of progressive dyspnea, edema of the lower extremities, and a fever with an unknown origin. A subsequent definitive evaluation showed him to be suffering from surgically accessible chronic thromboembolic pulmonary hypertension with a thrombus in the right ventricle. He underwent a pulmonary thromboendarterectomy and thrombectomy via a median sternotomy with intermittent circulatory arrest on November 24, 1994. Postoperatively he showed a marked improvement in his hemodynamic status and blood gas analysis. He has also returned to work with no trouble. Deep vein thrombosis appeared to be the pathogenesis of this case, but we could not find the origin of his unknown fever. He is currently being controlled by treatment with methylprednisolone as before.

2/456. Clinical implications of elevated PAI-1 revisited: multiple arterial thrombosis in a patient with essential thrombocythemia and elevated plasminogen activator inhibitor-1 (PAI-1) levels: a case report and review of the literature.

    Plasminogen activator inhibitor (PAI-1), a member of the serine protein family, is the most active in vivo inhibitor of fibrinolysis induced by plasminogen, tissue plasminogen activator (tPA), and urokinase type plasminogen activator (uPA). While the association between elevated PAI-1 and thrombogenesis has been well studied for several disease processes, including coronary disease, postoperative deep vein thrombosis (DVT), myocardial infarction, malignancy, and diabetes, few studies have concentrated on the correlation between elevated PAI-1 levels and thrombogenesis in patients with myeloproliferative disorders. Essential thrombocythemia (ET), a chronic myeloproliferative disorder, characterized by the overproduction of poorly functioning platelets, is associated with both thrombotic and hemorrhagic life-threatening complications. Although the events resulting in thrombogenesis in such patients may be multifactorial in nature, an association between elevated PAI-1 levels and thrombus formation has been proposed. Herein we present a patient diagnosed with ET complicated by multiple episodes of arterial thrombosis. Elevations in PAI-1 levels were documented repeatedly. The role of elevated PAI-1 when associated with other disease processes is also discussed.

3/456. Clinical and echocardiographic features of two large left atrial parietal thrombi.

    A 62-year-old woman with severe mitral stenosis and two large parietal thrombi inside the left atrium is described. The patient was admitted to the hospital because of heart failure. Transthoracic and transesophageal echocardiography showed a severe calcific mitral stenosis and two large (56.9 and 46.2 mm in diameter) parietal thrombi inside the left atrium attached to the interatrial septum and associated with severe spontaneous echo contrast. This severe spontaneous echo contrast was detected in the left atrium and in the left atrial appendage. The patient was referred for cardiac surgery. The two large parietal thrombi were removed, and the valve was replaced with a Sorin-Bicarbon mitral valve prosthesis. Intraoperative transesophageal echocardiography after replacement of the mitral valve prosthesis and removal of the thrombotic mass showed absence of any spontaneous echo contrast in the left atrium and in the left atrial appendage. This report describes the diagnostic approach and successful surgical treatment of two very large parietal thrombi inside the left atrium associated with severe mitral stenosis and atrial fibrillation, which is a rare occurrence.

4/456. portal vein thrombosis after splenectomy for hereditary stomatocytosis in childhood.

    portal vein thrombosis is a rare but potentially lethal complication in children requiring splenectomy. We report on a 15-year-old boy with a dehydrated hereditary stomatocytosis, who underwent splenectomy and presented a postoperative partial portal vein thrombosis. With prompt heparin therapy, neither propagation of the thrombus nor further cavernous transformation in the following occurred 6 years. CONCLUSION: Recent data suggest that hereditary stomatocytosis carries a high risk of thrombotic complications, especially after splenectomy. This procedure, the benefit of which is limited in this condition, should therefore be strongly avoided.

5/456. Right ventricular thrombosis early after bidirectional Glenn shunt.

    Thrombosis in the right ventricle occurred early after bidirectional superior cavopulmonary shunt in 2 patients with pulmonary atresia with intact ventricular septum and major right ventricular coronary artery communication, and perioperative brain infarction occurred in 1 patient. Clinicians should be aware of the hazards of this potentially lethal complication, and transfusion of platelets and fresh plasma should be minimized. Although the hemodynamic state is good, echocardiography should be performed frequently and strict anticoagulation should be started as early as possible.

6/456. Heterozygous prothrombin gene mutation: a new risk factor for early renal allograft thrombosis.

    BACKGROUND: Underlying thrombophilic disorders increase the risk of early allograft loss after renal transplantation. We report three cases of early graft thrombosis in two carriers of a recently discovered prothrombotic variation of the prothrombin gene. case reports: The first patient, an adolescent girl, developed multiple thrombotic shunt occlusions after the initiation of hemodialysis until continuous cumarin anticoagulation was instituted. During living-related kidney transplantation, peracute thrombosis of the renal arteries and veins occurred during surgery despite excellent intraoperative conditions and continuous low-dose heparinization. A few hours after reperfusion of the organ by immediate thrombectomy and intrarenal fibrinolysis, an irreversible rethrombosis occurred. A detailed evaluation of the coagulation system showed highly elevated prothrombin protein activity and concentrations. A heterozygous G-->A transition at position 20210 of the prothrombin gene was identified. Hemodialysis was resumed using recombinant hirudin, a direct and selective thrombin inhibitor, as an anticoagulant. The second patient, a girl with end-stage renal failure due to atypical hemolytic uremic syndrome, lost two cadaver kidney allografts, each time by massive thrombosis a few days after transplantation. In this patient also, elevated prothrombin activity and concentrations were present and a heterozygous G-->A transition at position 2210 of the prothrombin gene was detected. CONCLUSIONS: The prothrombin gene mutation is a new risk factor for thrombotic complications both on hemodialysis and after renal transplantation. It may be useful to screen for this disorder in the pretransplant thrombophilia work-up.

7/456. The formation of two layers detectable by intraoperative echocardiography is a reliable predictor of late thrombosis within the false lumen of a dissected aorta.

    The subjects consisted of one patient with chronic type A and three patients with chronic type B aortic dissection, who underwent replacement of an aorta obliterating distal false lumen. After the repair, the formation of two layers was detected by direct scanning echocardiography within the false lumen even during heparinization. In all cases, postoperative computed tomography confirmed complete thrombosis of the false lumen. The formation of two layers was considered to be a reliable predictor of late thrombosis.

8/456. Pediatric heparin-induced thrombocytopenia: management with Danaparoid (orgaran).

    heparin-induced thrombocytopenia is a rare and serious complication of anticoagulation therapy. There remains a paucity of information pertaining to alternative anticoagulation strategies for use during cardiopulmonary bypass concomitant with heparin-induced thrombocytopenia, especially in children. We report the successful treatment of heparin-induced thrombocytopenia and subsequent hemorrhagic complications postoperatively in a 2-year-old child with Danaparoid (orgaran). Emergent conduit revision with cardiopulmonary bypass was required for a thrombosed systemic-venous to pulmonary-arterial connection (completion modified fontan procedure). Required doses of Danaparoid were consistently twofold that previously reported for adults.

9/456. Surgical repair of type B aortic dissection complicated by early postoperative lung vein and artery thrombosis.

    A 24-year old man with marfan syndrome previously operated for abdominal aortic aneurysm and type A dissection sustained a type B dissection. He underwent graft replacement of the descending and upper abdominal aorta, complicated by infarction of the left upper lobe and lobectomy was carried out. The postoperative course was uneventful. The mechanism for this rare complication is discussed.

10/456. Idiopathic inferior mesenteric venous thrombosis demonstrated by angiography.

    Idiopathic thrombosis of the inferior mesenteric vein, not associated with portal vein thrombosis, is an uncommonly diagnosed lesion. We are reporting a case of inferior mesenteric vein thrombosis diagnosed preoperatively by angiography. We believe this to be the first case in the literature of this particular lesion demonstrated conclusively by angiography before surgery.
