1/347. Bilateral ophthalmoplegia and exophthalmos complicating central hemodialysis catheter placement.

    We describe a 58-year-old woman who presented with bilateral ophthalmoplegia, exophthalmos, and headache and was found to have retrograde internal jugular vein flow secondary to a high-grade obstruction of the ipsilateral brachiocephalic vein from a previous hemodialysis catheter placement. The patient had also a high-flow dialysis graft in the ipsilateral arm. The cranial and extracranial venous system congestion resolved, and the signs disappeared soon after a balloon angioplasty and stent placement at the level of the obstruction.

2/347. Posttraumatic intestinal stenosis presenting as a perforation: report of a case.

    A 78-year-old woman was admitted to the hospital after falling into a ditch approximately 1 m deep and sustaining a blunt abdominal trauma with a left femur fracture. On the tenth day after admission, symptoms of a small bowel obstruction occurred. A nasogastric tube was inserted, and the symptoms thus improved. She sometimes complained of abdominal pain during the 12 months after the fall, but recovered with conservative management. The next year, she was readmitted to the hospital for a pin extraction of the left femur bone. During this admission, 15 months since her admission after her fall, she again complained of abdominal pain. abdominal pain increased with a muscular defense, and abdominal x-rays revealed free air. She was referred to our hospital with a diagnosis of perforative peritonitis, and emergency surgery was performed. Upon laparotomy, circumferential stenoses of the small bowel were recognized in the proximal segments about 40cm, 80cm, and 100cm from the ileocecal region. In addition, a perforation and prominent dilatation of the bowel segment was observed just proximal to the stenosis about 100cm from the ileocecal region. She underwent a small intestinal resection at two sites. There were no findings of an intestinal specific ulcer, such as Crohn's disease, intestinal tuberculosis, or malignancy, based on the results of a histopathological examination.

3/347. Treatment of may-thurner syndrome with catheter-directed thrombolysis and stent placement, complicated by heparin-induced thrombocytopenia.

    may-thurner syndrome is an uncommon process in which the right common iliac artery compresses the left common iliac vein, resulting in left iliofemoral deep vein thrombosis and severe leg edema. We report the case of a 41-year-old female who presented with severe left leg edema present for 1 day. One week earlier she had experienced acute shortness of breath and pleuritic chest pain. Duplex ultrasound revealed a left iliofemoral deep vein thrombosis. A computed tomography (CT) scan performed for abdominal pain revealed thrombosis of the entire left common and external iliac veins. A ventilation-perfusion scan diagnosed a pulmonary embolism. The patient was treated with systemic intravenous heparin and catheter-directed thrombolysis of the iliofemoral deep vein thrombosis. Complete thrombolysis and iliofemoral vein patency was achieved over 5 days. A persistent stenosis in the left common iliac vein consistent with may-thurner syndrome was alleviated with percutaneous balloon angioplasty and placement of a Wallstent. heparin therapy was terminated at the time of stenting because of suspected heparin-induced thrombocytopenia. The patient was started on a continuous infusion of 10% dextran 40, and warfarin therapy was initiated. heparin-induced antibodies were confirmed by a C-14 serotonin release assay. The endovascular reconstruction remains patent 4 months later. heparin-induced thrombocytopenia complicating endovascular reconstruction of the iliofemoral venous system in a patient with may-thurner syndrome is an uncommon occurrence. This case and a review of the literature are discussed.

4/347. Marked increase in flow velocities during deep expiration: A duplex Doppler sign of celiac artery compression syndrome.

    Symptoms of chronic mesenteric ischemia develop when the celiac artery is constricted by the median arcuate ligament of the diaphragm. Lateral aortography is the primary modality for diagnosing ligamentous compression of the celiac artery. However, duplex Doppler sonography performed during deep expiration can cause a marked increase in flow velocities at the compressed region of the celiac artery and suggest the diagnosis of celiac arterial constriction due to the diaphragmatic ligament.

5/347. Segmental portal hypertension due to splenic vein obstruction: imaging findings and diagnostic pitfalls in four cases.

    Segmental portal hypertension due to isolated splenic vein obstruction is a rare but important entity as it is the only curable cause of portal hypertension by splenectomy. Four cases are presented illustrating the radiological features of splenic vein obstruction, and the diagnostic pitfalls that arose in patients with complicated clinical presentations.

6/347. A case of antiphospholipid antibody syndrome diagnosed after thrombosis of an arteriovenous shunt.

    A 32-year-old male dialysis patient with lupus nephritis was admitted because of shunt obstruction. The arteriovenous fistula was reconstructed, but obstruction recurred twice within several hours after surgery. A high blood level of anticardiolipin beta2-glycoprotein I antibody suggested that shunt obstruction was caused by a thrombotic tendency related to the antiphospholipid antibody syndrome. Accordingly, for the third shunt procedure, antiplatelet therapy (which had been commenced for systemic lupus erythematosus) was combined with dalteparin sodium from before surgery and warfarin was added postoperatively. This regimen prevented shunt obstruction. In conclusion, hemodialysis patients who suffer repeated shunt obstruction should be examined for antiphospholipid antibody syndrome.

7/347. may-thurner syndrome in an adolescent: persistence despite operative management.

    We describe a patient with may-thurner syndrome who underwent operative transection and transposition of the right common iliac artery without direct venous repair, because preoperative and intraoperative intravascular ultrasound scans were negative for "spurs" in the left common iliac vein. When symptoms and signs persisted, a postoperative magnetic resonance venogram (MRV) showed severe stenosis in the left common iliac vein. Progressive, but incomplete, clinical improvement occurred with conservative management.

8/347. Blocking of the hepatic vein outflow by neointima covering a wallstent across a membranous stenosis of the inferior vena cava.

    A 31-year-old man presented with idiopathic membranous obstruction of the suprahepatic inferior vena cava (IVC) and was treated by balloon dilation and placement of a Wallstent. The patient improved markedly. However, he developed obstruction of the hepatic vein outflow secondary to neointima formation over the stent that covered the hepatic vein ostia. The patient died of liver failure and septicemia. We believe that this is the first report of such a serious complication.

9/347. Successful treatment of a saphenous vein graft perforation with an autologous vein-covered stent.

    A 52-year-old man with a history of prior coronary bypass surgery suffered recurrent angina and underwent percutaneous placement of a stent within the midportion of the saphenous vein graft to the marginal branch of the left circumflex coronary artery, which was complicated by a significant perforation. The perforation was successfully closed using an NIR stent covered with a segment of autologous antecubital vein. Subsequent surgical exploration confirmed successful closure of the perforation.

10/347. Trepopnea due to recurrent lung cancer.

    Trepopnea is a condition whereby breathing may be comfortable in one position but difficult or labored in another. A unique case with trepopnea due to recurrent lung cancer with right main pulmonary artery stenosis and left main bronchus obstruction is presented. The patient had developed trepopnea 3 months earlier, but developed orthopnea shortly before he was admitted to our hospital. An emergent wall stent implantation was performed via the right femoral vein in the sitting position with the patient's leg stretched out. The symptoms and respiratory function improved after stent implantation.
