1/166. 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.

2/166. Assessment of outcome by EC/IC bypass with 123I-iomazenil brain SPECT.

    We report two patients with occlusive cerebrovascular disease who were examined by means of benzodiazepine receptor SPECT(BZR-SPECT) with 123I-iomazenil (IMZ) before extracranial-intracranial bypass surgery (EC/IC bypass). Preoperative low perfusion areas detected by cerebral blood flow SPECT (CBF-SPECT) were divided into two parts on BZR-SPECT images. In the low perfusion areas where the BZR were preserved, regional cerebral blood flow (rCBF) increased on postoperative CBF-SPECT, but where the BZR were not preserved, rCBF did not increase on postoperative CBF-SPECT. On visual inspection, the SPECT images of postoperative CBF-SPECT appeared similar to those of preoperative BZR-SPECT. For evaluation of the ischemic brain condition itself, instead of the cerebral metabolism, the distribution and activity of cerebral neurons indicated by BZR-SPECT with IMZ might be utilized.

3/166. popliteal artery entrapment syndrome: specific aspect.

    A case of popliteal artery entrapment syndrome (PAES) is reported. A non smoker, 63-year-old man, consulted for severe claudication of the lower limb, with a sudden onset. There was no past history of vascular disease. Neither the arteriography nor the arterial doppler led to definite diagnosis. In our case, only the C.T. scan was contributive to the diagnosis. The age, 63, at which this abnormality became symptomatic, the abrupt appearance of ischaemic symptoms and the embryologic type of the arterial stenosis were particular. The surgical management was the only therapeutic option.

4/166. Interventional therapy of vascular complications caused by the hemostatic puncture closure device angio-seal.

    The hemostatic puncture closure device Angio-Seal is a quick, safe, and easy-to-use system, allowing rapid sealing of the vascular access site following coronary angiography and interventional procedures. It is advantageous for patients in whom early mobilization is desired and may therefore decrease hospital costs. Despite the documented low complication rate, there are some specific problems. Reporting on five cases, we describe problems in diagnosis and possible interventional therapy of Angio-Seal-associated complications such as stenosis, occlusion, or peripheral embolism. Our experience led to the concept of precise diagnosis in any patient with leg symptoms and early interventional treatment with the aim of complete removal of the intra-arterial parts of the Angio-Seal device. Any delay in diagnosis and treatment increases the risk of additional thrombotic occlusion. Spontaneous dissolution of the Angio-Seal sponge limits interventional possibilities of complete removal.

5/166. Peripheral vascular disease in Behcet's syndrome.

    We describe a patient with Behcet's syndrome who had peripheral vascular disease involving the left subclavian artery for which angioplasty with stent placement was performed and reangioplasty done for in-stent restenosis. She presented with recurrence one year after stent placement; angiography revealed diffuse disease of the axillary and radial arteries with mild to moderate restenosis at the site of stent placement.

6/166. A diabetic patient with a black penile tip.

    This is a report of a patient with diabetes mellitus type II who presented with the rare complication of penile gangrene. The gangrene was unilateral and was associated with ipsilateral partial stenosis of the common iliac artery. An angioplasty followed by insertion of a stent, rehydration, and improved diabetic control did not improve the penile lesion, and penile amputation was carried out. In the postoperative period, the patient developed a bilateral basal pneumonia with a significant growth of saprophyte mycobacterium gordonae from the bronchial aspirate. This is the first reported case of unilateral penile gangrene and also that of mycobacterium gordonae infection in a patient with diabetes mellitus.

7/166. osteomyelitis of the spine and abscess formation in the left thigh after stent-graft implantation in the superficial femoral artery.

    PURPOSE: To present a rare case of abscess formation around a covered stent in the superficial femoral artery. methods AND RESULTS: Two weeks after balloon dilation of a left superficial femoral artery (SFA) occlusion, during which a Hemobahn covered stent had been placed to treat dissection, a 77-year-old nondiabetic male developed intolerable pain and swelling of his left thigh. An abscess had formed around the stent, which was patent; intravenous antibiotic therapy quelled the symptoms, and the patient discontinued his oral antibiotic regimen weeks after discharge. General septicemia ensued. Acute lower limb ischemia and excruciating back pain prompted readmission. The SFA stent-graft occlusion required femoropopliteal bypass; the abscess and spondylodiskitis that had developed in the T12 and L1 vertebrae responded to intravenous antibiotics. The patient is without signs of infection at 6 months. CONCLUSIONS: Local and systemic infections associated with intraluminal prostheses are rare, and prophylactic antibiotic therapy is not commonly employed. Balloon- or device-induced arterial injury may expose the arterial wall to bacterial colonization, suggesting that patients receiving lengthy stents or experiencing arterial injury during angioplasty should receive antibiotics as a precautionary measure.

8/166. Fatal anaphylactic reaction to protamine after femoropopliteal by-pass surgery.

    BACKGROUND AND AIMS: Administration of protamine might cause serious complications especially in patients treated preoperatively with NPH insulin. MATERIAL AND methods: A case report. RESULTS AND CONCLUSION: Administration of protamine sulphate caused fatal anaphylactic reaction to a diabetic patient undergoing femoropopliteal by-pass surgery. Care should be taken when administering protamine to a patient treated preoperatively with NPH insulin and the possibility of an anaphylactid reaction to protamine have to be kept in mind.

9/166. Integrated minimally invasive approaches for the treatment of atherosclerotic vascular diseases: Hybrid procedures.

    patients may develop simultaneous symptoms of atherosclerotic vascular disease from different arterial beds. A concurrent minimally invasive approach to the management of these clinical situations may be an advantage over conventional surgical procedures. This study describes two separate case series of patients undergoing coronary/peripheral (n = 38) and peripheral/peripheral procedures (n = 10). Technical and clinical success was achieved in all patients. There were two periprocedural complications (retroperitoneal bleed and septicemia) in the coronary/peripheral series and no complications in the peripheral/peripheral series. We also present five case reports to illustrate the utility of hybrid procedures in various clinical settings. This study suggests that the use of simultaneous or sequential minimally invasive procedures appears to be a safe and feasible strategy for the treatment of patients with symptoms from more than one vascular bed.

10/166. hypertension due to renal artery occlusion in a patient with antiphospholipid syndrome.

    We report an unusual case of renovascular hypertension in a 16-year-old boy with primary antiphospholipid syndrome (PAPS), admitted to our clinic for severe drug-resistant hypertension and hypokalemia. Hormonal investigation revealed secondary aldosteronism and positive captopril test for renovascular disease. aortography confirmed the occlusion of the left renal artery. After nephrectomy, normalization of blood pressure and secondary aldosteronism occurred. Presently the patient remains in good health, receiving warfarin anticoagulant therapy. PAPS is defined by the presence of antiphospholipid antibodies and recurrent thrombosis. Arterial thrombosis (29%) appears to be less prevalent than venous thrombosis. Thrombotic microangiopathy of the kidney is frequently observed but renal artery occlusion, as seen in our patient, is unusual.
