An acute anteroseptal infarction was diagnosed in a 51-year-old man whose ECG showed ST elevations in leads V1-V4 after acute retrosternal pain for about 20 min. Angiography revealed proximal occlusion of the right coronary artery, while the dominant left coronary artery was fully patent. After successful recanalization of the right coronary artery with intracoronary infusion of urokinase, the ST elevations quickly disappeared and impending right-heart infarction was avoided. Isolated right-heart infarction can imitate the ECG pattern of anteroseptal infarct and should be considered if the height of ST elevations diminishes from V1 to V4.

In a 37-year-old female patient complaining of increasing pain in the neck and occiput, chiropractic manipulations at the cervical vertebral column were associated with ischaemias of the brain stem presenting as vertigo, transient "locked-in" syndrome followed by vomiting, and sensorimotor hemiparesis. Digital subtraction angiography (DSA) revealed complete obstruction of the right and slight dissection of the left vertebral artery. The symptoms receded within a few days after heparinisation with 1000 IU/h intravenously. A 39-year-old female patient developed vertigo, nystagmus, tetraparesis and dysarthria two days after chiropractic intervention because of refractory pain in the neck and occiput. DSA showed embolism of the basilar artery and extensive dissections of the vertebral arteries. The basilar artery was completely recanalized after local intraarterial fibrinolysis with 50,000 IU urokinase. During the further course of treatment the symptoms receded under heparin and phenprocoumon over a period of 8 months, except for hemiparesis on the left side especially affecting the arm. Trivial traumas can result in dissections of the vertebral arteries. Severe neck pain is a frequent, typical early symptom. Hence, patients with cervical vertebral column syndromes should receive chiropractic treatment only after careful diagnosis.

A 19-year-old girl had for four weeks the clinical signs of recurrent pulmonary emboli and deep-vein thrombosis (tachycardia, dyspnoea, right inguinal pain), which had been misdiagnosed. The correct diagnosis was made only after drastic deterioration in her condition following appendicectomy for falsely diagnosed appendicitis. Urokinase infusion (80,000-160,000 IU/h for 11 days) having failed to bring about improvement, much greater than ultra-high much less than thrombolysis with streptokinase was begun (250,000 IU streptokinase over 30 min, followed by 9 million IU over 6 hours). Fatal pulmonary embolism occurred seven hours after the end of the infusion. Autopsy revealed extensive separation of thrombotic material in the pelvic veins. This observation and other reports should serve as a warning against using streptokinase in ultra-high doses if large veins, as those in the pelvis, are involved.

A patient with severe hand ischemia due to Buerger's disease was treated by a rapidly effective modification of percutaneous catheterization. Accelerated mechanical and pharmacologic thrombolysis of an occluded palmar arch with 200,000 U urokinase and subsequent small vessel angioplasty abolished pain and restored digital perfusion within 40 min.

Thrombolytic therapy has recently gained ascendance as an accepted form of treatment for acute myocardial infarction. Since the majority of patients with acute infarction have an occlusive coronary thrombus, plasminogen activators administered to these patients generate plasmin that proteolysis the fibrin elements of the thrombus and thereby reestablishes coronary patency. In addition to the conventional agents streptokinase and urokinase, newer, more fibrin-selective plasminogen activators are currently available for use or study, including tissue plasminogen activator and pro-urokinase. In acute myocardial infarction, the agents that have been studied most extensively are streptokinase and tissue plasminogen activator. Among the major recent studies of the use of these activators, several important observations have been made, including the need for administration of agent within 3 hours of the onset of pain, the efficacy of the intravenous route of administration, significant reduction in mortality with early administration, and significantly improved left ventricular function with early administration. Haemorrhagic complications remain a problem, but with judicious dosing their incidence can be kept to a minimum. Early studies in patients with unstable angina suggest that plasminogen activators may also have a role in the management of this clot-dependent disorder.

2 cases of thromboembolism in young women with no risk factors except use of triphasic oral contraceptives are reported. A 21-year old White woman, Gravida I Para I, presented to the emergency room with a painful, blue, mottled right lower leg after pain in the hip and buttock for 1 week. She had taken a triphasic oral contraceptive containing 35 mcg ethinyl estradiol and 0.5, 0.75, 1 mg norethindrone for 1 month, and had no other related history. Doppler and venogram tests showed thrombosis of the ileal, femoral, popliteal and infrapopliteal veins. She was treated with heparin, streptokinase, and urokinase without success and recovered after ileal, femoral and popliteal thrombectomy. The 2nd case was a 30-year-old Gravida III Para I Black woman who had taken a pill containing 50 mcg ethinyl estradiol and 500 mcg norgestrel for 13 years and had recently switched to the triphasic pill described above. She had dull midepigastric pain, nausea, vomiting, diarrhea and chills, for 1 week. Physical exam was negative except for abdominal tenderness and a heart murmur. Abdominal ultrasound revealed portal venous thrombosis extending to the splenic and superior mesenteric veins. She was treated with transhepatic urokinase without effect and celiotomy was performed. She was discharged with an occluded right branch of the portal vein. These cases point out the fact that the estrogen dose in triphasic pills is not lower than that in low dose combined oral contraceptives.

A 55-year-old man developed acute inferior myocardial infarction. A coronary arteriogram performed within two hours later showed complete occlusion of the right coronary artery, which was not resolved by two doses of 300 micrograms of intracoronary nitroglycerin. It was recanalized with 50% luminal diameter narrowing after 600,000 units of urokinase. Immediately after this thrombolytic therapy, the patient experienced chest pain, and the coronary artery became completely obstructed again. The pain was promptly relieved by 300 micrograms of intracoronary nitroglycerin, with disappearance of the obstruction. The observations during the procedure indicate that coronary artery spasm can occur after successful thrombolytic therapy on an occluded artery, inducing postinfarction angina, and might culminate in a second complete occlusion after percutaneous transluminal coronary recanalization.

Pulmonary embolism following postoperative deep venous thrombosis is a very serious complication with a high mortality rate. Though this disorder has been thought to be rare in Japanese, its occurrence seems to be increasing recently because of changes in eating habits, increase of average age and the frequent practice of venous catheterization. Two cases of the pulmonary embolism following deep venous thrombosis after surgery are reported, and possible causes of the deep venous thrombosis are discussed. Case 1: A 48 year-old obese female was operated on for a posterior fossa dural arteriovenous malformation. On the 4th postoperative day, she developed a pain and swelling in the left leg and low back pain. On the 18th postoperative day, she fell into a state of shock following the sudden onset of a severe back pain and respiratory distress. After diagnosis of the pulmonary embolism, she was immediately treated with urokinase, warfarin and aspirin. Her obesity was considered to be one of the risk factors of the postoperative deep venous thrombosis. Case 2: A 62 year-old female with a ruptured cerebral aneurysm could not get out of bed because of postoperative mental disturbance. A central venous pressure catheter was inserted into the right femoral vein for two weeks postoperatively. One month after surgery, she complained of swelling and a dull pain in the right leg without cardiorespiratory symptoms. Lung perfusion scintigraphy showed asymptomatic pulmonary embolism. She was treated immediately. Both long bed rest and femoral venous catheterization were considered as risk factors possibly leading to deep venous thrombosis.(ABSTRACT TRUNCATED AT 250 WORDS)

The study concerns 31 cases of parenteral fibrinolysis performed at the acute stage of myocardial infarction in 30 patients (mean age: 51.9 years), treated less than 4 hours and 15 minutes after the onset of pain. The treatment with streptokinase (80.65%), BRL 26 921 (12.90%) and urokinase (6.45%) was undertaken within a mean time of 3 hours and 17 minutes +/- 53 min. Revascularization defined by the disappearing of pain, the sudden flattening of ST with presence of Q wave, was obtained in 71 p. cent of patients before the 6th hour. The study of the CK curve shows that the enzymatic peak is reached earlier in these patients (13 hours 23 vs 19 h 42). Severe arrhythmias are rare (VF: 0%, transient AVB III: 3.2%). VAIRs were only observed in patients revascularized at an early stage (p 0.02) and in 54.5 p. cent of them. It seems to concern the largest M.Is, treated and revascularized later, regardless of the artery concerned. The syndrome bradycardia-hypotension (Bezold-Jarisch reflex) is only found in patients revascularized at an early stage (22.7 p. cent). Late VES (RR' RR-200 ms or fusion) are more frequent in patients revascularized at an early stage. These three benign rhythm disorders which do not usually require treatment, seem to be good success criteria of fibrinolysis but cannot be considered as predictive indications of myocardial protection.

Kinetics of the catalytic activities of creatine kinase (CK;EC 2.7.3.2) for three CK-3 and two CK-2 isoforms in serum were studied in 20 patients with myocardial infarction randomly assigned to receive either intracoronary urokinase (group A) or conventional therapy (group B). The temporal characteristics of isoform changes described were (a) time at which the isoform activities are significantly greater than initial values, (b) maximal rate (Ka) at which isoforms are released into blood, (c) time lag from onset of pain until maximum activity value, (d) peak value of each serum isoform, and (e) rate (Kd) at which each isoform is cleared from serum. Thrombolytic treatment induced earlier peak times in group A: for CK-3(3), 7.4 vs 20.0 h; for CK-3(2), 11.6 vs 24.8; for CK-3(1), 18.6 vs 34.3; for CK-2(2), 9.1 vs 17.8; and for CK-2(1), 11.8 vs 26.8 (numbers given are medians; for all isoforms, P less than 0.05). Ka values were at least twofold greater and the first increase was significantly earlier in the urokinase group. Consequently, the ratio for CK-3(3) to CK-3(1) activities peaked significantly earlier in group A. Isoform peak activities and Kd were not significantly different between the two groups.
