A 61-year-old white woman, who had progressive arthritis over a two-year period, developed bilateral peripheral corneal degeneration. The superior cornea thinned to a thickness of approximately two thirds of normal. She died suddenly in the hospital and a primary occlusive vasculitis of the anterior ciliary arteries within the superior rectus muscles was found. There was necrotizing arteritis in the lungs, kidneys, adrenal caps, spleen, fallopian tubes, and skeletal muscle. The observation of an occlusive vasculitis of the anterior ciliary arteries in this patient supports the belief that ischemia may play a major role in peripheral marginal degeneration of the cornea.

The authors recently treated three patients showing rather marked complications following sclerosing injections for varicose veins. In the first case, the intra-arterial injection brought about a tissular necrosis in the form of a distal-based triangle. The preservative treatment, undertaken 4 weeks after the injection, did not make it possible to save three toes, that had to be amputated. The second patient was sent to use after an injection in the posterior tibial artery. Acute ischemia was treated on an emergency basis with a lumbar sympathectomy. I believe that the approach we took allowed us to cure the trophic problems and to loose only one small phalanx. The third case reported on concerns a patient brought to us in a state of shock after a massive pulmonary embolism. She had been given a sclerosing injection in a large varicose vein of the leg 48 hours previously. The leg had rapidly increased in volume and was apparently the site of a deep veinous thrombosis.

We report on a 5-year-old child who survived an intracerebral crisis, following ketoacidosis-revealing diabetes (DKA), with visual impairment due to a vascular occipital lesion. Two and 4 months after the initial episode, a unique hypothalamopituitary disorder consisting in GH, ACTH, TSH deficiencies and central precocious puberty, was detected. Cranial magnetic resonance images showed no visible lesion in the hypothalamopituitary region. The most likely hypothesis is the ischemia of hypothalamopituitary and occipital regions following possible cerebral edema after hyperhydration. She survived with low visual acuteness and received a combined replacement therapy for the neuroendocrinological deficiencies. This case emphasizes that the rehydration at the initial period of DKA is critical, especially when risk factors for cerebral edema are present (young age, marked hyponatremia). The neuroendocrinological consequences of acute cerebral edema are rare, but physicians must be attentive in survivors of these accidents.

3 cases of popliteal artery occlusion are described, in 2 young Israeli women and a young man, and the etiologic factors in this rare disorder are reviewed. The 1st case was a 20-year old healthy woman with no contributing factors except use of low dose oral contraceptives for 5 months. She had suffered for 3 months with claudication of her left leg. Her Doppler ankle-brachial index was 0.7, and her angiogram showed complete occlusion of the popliteal artery and partial occlusion of the tibio-peroneal. She was treated with aspirin and cardoxine, discontinuation of oral contraceptives and walking, and recovered. The 2nd case was a 33-year old woman with history of rheumatic fever, obesity, hirsutism, venous thrombosis, hormone therapy for infertility, multiple spontaneous abortions, smoking, and possible Cushings disease. Her findings included and AB index of 0.45 on the right, and spotty stenosis of the popliteal artery. She was treated surgically with a Fogarty catheter, and is well 3 years later with the help of anticoagulants. The 3rd patient was a 30-year old male athlete who smoked heavily. He had an AB index of 0.4 on the left and complete blockage of the popliteal artery, so he received longitudinal arteriotomy and thrombectomy. He was put on anticoagulants, and is well, 6 months after surgery. Oral contraceptives were considered the likely cause of the 1st young woman's claudication, and possibly involved in the 2nd patient's ischemia. It is usually difficult to define the cause of isolated popliteal artery occlusion in young adults. Multidisciplinary management with thrombolytics or surgery should be considered, and discontinuation of oral contraceptives should be a priority, especially if a young woman began using them in the last year.

In 1983, a previously healthy 21-year old mother came to University Hospital in Dijon, France feeling weak and had a severe frontal headache with vomiting. Clinical and biochemical tests were normal. She smoked 20 cigarettes/day and used a high dosed combined oral contraceptive (OC) (ethinyl estradiol and cyproterone acetate). 15 days later, the headache returned and she could not understand spoken words and the bilateral section of the brain had slowed. Yet her mental status was normal as were cerebrospinal fluid and cerebral computerized tomography tests. The antiherpes virus drug, vidabarine, did not alleviate symptoms. At least 1 month later, a severe left pulmonary embolism caused acute right heart failure. She also had a prethrombotic left iliac vein, so physicians began heparin therapy, adding nifedipine and buflomedil to control the spasms in the right internal iliac artery and both external iliac arteries. Acute ischemia of the lower limbs eased within a week but sensory disorders remained for 2 months. Satisfactory collaterality transpired due to a blocked left external iliac artery and left iliac vein. The following signs and symptoms indicated her condition to be homocystinuria: blond hair with deep blue eyes, macrocytic anemia, factor VII deficit (51%), strong positive Brandt's reaction, cystine homocystine in the plasma, and presence of homocystine, cystathionine, and methionine in the urine. Physicians took her off the OC and discharged her on vitamin B6/day, folic acid/day, betaine citrate/day, and the anticoagulant Coumadin. A subsequent check of her 19-year old sister found she had it too. They assessed the patient's condition yearly. In 1988, her left leg developed edema and she limped when not using elastic stockings. Effects of iliac vein phlebitis were evident. She no longer suffered from headaches. Since plasma methionine was within the normal range and homocystine no longer was present in plasma and urine, the physicians halted the anticoagulant therapy. In conclusion, the OC precipitated this partial form of homocystinuria.

A 28-year-old female, addict to cocaine and with acute myocardial infraction is reported. The patient was obese and smoked 17 cigarette packs per year. She had been consuming about 250 mg of cocaine daily for the last months until 2 weeks before admission. Coronary angiography showed a 100% stenosis of the left anterior descending artery. Although the vasospastic effect of cocaine on the pathogenesis of coronary ischemia in addicts is well known, most patients reported in the literature show coronary artery stenosis. This may lead to hypothesize about a likely atherogenic role of cocaine.

A woman had diffuse vascular spasm related to cocaine use. She presented with evidence of an acute anterior myocardial infarction but had no rise in creatinine phosphokinase levels. Cardiac catheterization showed 90 percent proximal left main coronary artery narrowing. The catheterization was complicated by right femoral artery spasm. A repeat catheterization after treatment with nitroglycerin and diltiazem showed 30 percent proximal left main coronary artery narrowing. This catheterization was complicated by left femoral artery spasm. An exercise treadmill test was negative for ischemia.

A 51 year-old woman presented with sudden loss of vision secondary to serous neuroretinal detachments of both maculas. Fluorescein angiography revealed multiple hyperfluorescent pin-point dots in the early phases. The areas of fluorescein hyperfluorescence became more diffuse as dye leaked into the subretinal space. The diagnostic of acute monoblastic leukemia was made. Following treatment, her vision improved. Fundus examination at that time showed resolution of the bilateral serous retinal detachment. She died one month after the onset of visual complaints and autopsy was refused. There have been 14 previous reports of acute leukemia with serous retinal detachment. In most cases, retinal detachment occurred as the presenting sign or during relapse of the systemic disease. It was often bilateral and located in the posterior pole. Histopathologic studies showed leukemic infiltration of the choroid with areas of degeneration and proliferation of the retinal pigment epithelium. Angiographic findings are similar to what is observed in choroidal ischemia. The relationships with macular serous retinal detachment and choriocapillaris occlusion are discussed.

This is the first report of re-aortocoronary bypass for Kawasaki's disease. The patient is a 22-year old female. She was afflicted with Kawasaki's disease at the age of 6 and had the symptom of angina pectoris at the age of 9. She went through the first aortocoronary bypass, to the left anterior descending artery (LAD) and the right coronary artery (RCA) with saphenous vein graft (SVG). After the first operation, the graft to LAD occluded totally, but she remained asymptomatic and well for 11 years. She had a sudden recurrence of anginal attack at the age of 20. The examinations confirmed ischemia of the anterior wall (LAD area) and the lateral wall (LCX area). Coronary angiography revealed patent SVG with a moderate sign of sclerotic change. We decided on re-aortocoronary bypass, left mammary artery to LAD and gastroepiploic artery to LCX, when she was 22-years old. LIMA was anastomosed to LAD, but LCX was not revascularized, because LCX was not identified and exposed in the operation. In spite of incomplete revascularization, postoperative stress ECG test was negative. Tl-myocardial scintigram confirmed no ischemia of the anterior wall and greatly reduced ischemia in the lateral wall. She became asymptomatic and returned to normal life.

We report the case of a 74-year-old woman with multi-level arterial occlusive disease and severe ischemia of the right lower extremity who underwent a re-operative femoro-femoral and a right femoro-popliteal bypass graft. Her right foot remained non-viable post-operatively despite patent grafts. She then underwent a 12-hour infusion of urokinase through a percutaneously placed popliteal artery catheter during that first post-operative day, with salvage of the right leg.
