1/191. Percutaneous fenestration of the aortic dissection membrane in malperfusion syndrome.

    We present two cases of malperfusion syndrome due to aortic dissection type-B. A supra-renal blind sac phenomenon resulted in renal failure and absent femoral pulses in both patients. Additionally, one patient suffered from spinal cord ischemia, the other from severe abdominal pain. By interventional techniques, catheter perforation of the blind sac was achieved. The resulting re-entries were enlarged with a balloon catheter. Distal perfusion without pressure gradients was restored by this technique in both patients and resulted in complete relief of symptoms. Percutaneous fenestration of the aortic dissection membrane may be an alternative to operative treatment in malperfusion syndrome.

2/191. Superior and inferior limb ischaemia in giant cell arteritis: angiography follow-up.

    giant cell arteritis most often affects the superficial temporal artery. Arterial territories such as the facial, carotid, myometrial and upper and lower limb arteries may be affected. In this paper we describe the case of a 52-year-old patient with upper and lower limb ischaemia who presented with grade III ischaemia in the left lower limb. giant cell arteritis was diagnosed as responsible for the symptoms. After treatment with corticoids, an angiographic improvement was evidence after 2-year period. The low number of reported cases, the diverse symptoms and varied course make diagnosis of GCA difficult. Therefore, GCA must be taken into consideration in the ischaemia of inferior and superior limbs whether isolated or simultaneous.

3/191. The use of alteplase in a newborn receiving extracorporeal membrane oxygenation.

    OBJECTIVE: To present a case of the use of alteplase for the successful resolution of an upper extremity occlusion in a newborn receiving extracorporeal membrane oxygenation (ECMO). CASE SUMMARY: A two-day-old full-term Hispanic girl receiving ECMO support developed a left upper extremity occlusion distal to the brachial artery. Alteplase therapy was initiated with a bolus dose of 0.48 mg/kg followed by a continuous infusion of 0.27 mg/kg/h for three hours. A repeat Doppler ultrasound revealed little improvement, resulting in continuation of alteplase therapy at an infusion rate of 0.27 mg/kg/h for an additional three hours. At the completion of the infusion, perfusion was greatly improved with palpable radial pulse present. While remaining on ECMO support, a brain ultrasound approximately 13 hours after alteplase therapy revealed a grade I right caudate head hemorrhage with normal ventricles. ECMO support was discontinued during the next 24 hours, with a repeat brain ultrasound three days later indicating no acute hemorrhage, normal ventricles, and almost complete resolution of the intraventricular hemorrhage. The neonate was discharged 19 days after discontinuing ECMO support. DISCUSSION: patients receiving ECMO support are at risk of hematologic complications, including thrombi formation. Moreover, limited information is available regarding the most appropriate thrombolytic therapy for patients receiving ECMO support. Alteplase is an attractive thrombolytic agent given its antigenicity, clot specificity, and pharmacokinetic profile. However, both ECMO support and thrombolytic therapy are risk factors for the development of intraventricular hemorrhage, which our patient developed. Therefore, close monitoring of patients receiving ECMO support and alteplase therapy is essential given the potential for hematologic adverse effects. CONCLUSIONS: Alteplase is an effective thrombolytic agent in neonates receiving ECMO support. Additional experience with alteplase is necessary to determine the optimal dose and duration of therapy in this patient population.

4/191. Vertebrobasilar artery territory infarction as an initial manifestation of systemic lupus erythematosus.

    cerebral infarction is a well-documented complication of systemic lupus erythematosus (SLE), that usually occurs several years after the diagnosis of SLE. To our knowledge, however, strokes associated with vertebrobasilar artery involvement were not reported to present as an initial manifestation of SLE. We report two patients, who presented with vertebrobasilar territory infarction as an initial manifestation of SLE. Patient 1 was a 16-year-old girl, who developed dysarthria and ataxia. MRI showed multiple infarcts in the pons, cerebellum and thalamus. Four-vessel cerebral angiography showed multifocal stenoses in the vertebral and basilar arteries with beaded appearance. Patient 2 was a 26-year-old woman, who developed headache associated with dysarthria, dizziness and ataxia. MRI showed multiple infarcts in the cerebellum, medulla, pons, midbrain and thalamus. cerebral angiography revealed occlusion of both vertebral arteries at the first cervical vertebral level with non-visualization of the basilar artery. Both patients were diagnosed as having SLE supported by laboratory results. Although rare, posterior circulation stroke can present as an initial manifestation of SLE, which may be attributed to vasculitis or dissection in the vertebral/basilar artery.

5/191. Peripheral arterial occlusion in acute promyelocytic leukemia.

    A 16-year-old Caucasian teenager developed fatigue, abdominal pain, pneumonia, and subsequently acute vascular occlusion of the left superficial femoral artery. Vascular assessment and heparin therapy lead to bone marrow aspiration and a diagnosis of acute promyelocytic leukemia. Treatment with chemotherapy prevented loss of limb and avoided further vascular surgery. Young patients with acute vascular occlusion require an in-depth assessment including attention to hematological disorders. Clots obtained on thromboembolectomy should be sent for pathological assessment and not discarded, especially in an unusual-age patient for arterial embolus.

6/191. diagnosis of intermittent vascular claudication in a patient with a diagnosis of sciatica.

    BACKGROUND AND PURPOSE: The purpose of this case report is to illustrate the importance of medical screening to rule out medical problems that may mimic musculoskeletal symptoms. CASE DESCRIPTION: This case report describes a woman who was referred with a diagnosis of sciatica but who had signs and symptoms consistent with vascular stenosis. The patient complained of bilateral lower-extremity weakness with her pain intensity at a minimal level in the region of the left sacroiliac joint and left buttock. She also reported numbness in her left leg after walking, sensations of cold and then heat during walking, and cramps in her right calf muscle. She did not report any leg pain. A medical screening questionnaire revealed an extensive family history of heart disease. Examination of the lumbar spine and nervous system was negative. A diminished dorsalis pedis pulse was noted on the left side. Stationary cycling in lumbar flexion reproduced the patient's complaints of lower-extremity weakness and temporarily abolished her dorsalis pedis pulse on the left side. OUTCOMES: She was referred back to her physician with a request to rule out vascular disease. The patient was subsequently diagnosed, by a vascular specialist, with a "high-grade circumferential stenosis of the distal-most aorta at its bifurcation." DISCUSSION: This case report points out the importance of a thorough history, a medical screening questionnaire, and a comprehensive examination during the evaluation process to rule out medical problems that might mimic musculoskeletal symptoms.

8/191. Intraaortic growth of hydatid cysts causing occlusion of the aorta and of both iliac arteries: case report.

    A woman who had been operated on previously for a paraspinal hydatid cyst presented with claudication of the lower limbs. Computed tomographic and magnetic resonance images showed multiple cysts in the soft tissues of the back, retroperitoneum, and lumen of the aorta and iliac arteries. Occlusion of the aorta and iliac arteries by recurrent hydatid cysts after previous surgery was confirmed with angiography and subsequent surgical exploration. The authors present the imaging findings of this unusual manifestation of cystic echinococcosis.

9/191. Successful transcatheter embolization of a pancreaticoduodenal artery aneurysm in association with celiac axis occlusion: a case report.

    We report a case of a pancreaticoduodenal artery (PDA) aneurysm in association with celiac axis occlusion. A 54 year-old female complaining of abrupt onset of abdominal pain was admitted to our hospital. On admission, abdominal CT examination revealed a hematoma in the retroperitoneal space. Selective superior mesenteric artery (SMA) angiography disclosed an aneurysm in the anterior inferior pancreaticoduodenal artery (AIPDA). The celiac axis was occluded and blood was flowing to the liver and spleen via the enlarged pancreaticoduodenal arcade from the SMA. Transcatheter embolization of the aneurysm was performed successfully. Up to 1996, there have been 37 reported cases of PDA aneurysm in association with celiac axis stenosis or occlusion, including this one. Transcatheter embolization was performed successfully in only 5 of these cases. The formation of this type of PDA aneurysm is thought to be a result of the increased blood flow in the pancreaticoduodenal arcade due to celiac axis stenosis or occlusion. The transcatheter embolization performed in our report produced a far greater blood flow, which may lead to further aneurysmal formation. Careful follow-up is therefore necessary.

10/191. A subclavian artery aneurysm associated with aortitis syndrome.

    We performed surgery on a 61-year-old woman who had increasingly severe right shoulder pain and paresthesia in her right upper extremity as a result of a large right subclavian artery aneurysm. She had suffered from aortitis syndrome for 10 years for which she was treated with steroids and had multiple arterial lesions, including bilateral subclavian artery aneurysms, abdominal aortic aneurysm and obstruction of bilateral superficial femoral arteries. The right subclavian artery aneurysm measured 4 cm in diameter and rupture appeared imminent, prompting surgical therapy. Via the supraclavicular incision approach and additional partial sternotomy, the aneurysm was excluded and the brachiocephalic to right axillar arterial bypass was set up using an extended polytetrafluoroethylene graft. The patient recovered without complications and a subclavian artery aneurysm demonstrated by computed tomography was thrombosed 1 month after surgery. In conclusion, we recommend the exclusion technique to treat subclavian artery aneurysms in cases in which aneurysmectomy is likely to injure adjacent veins and nerves.
