An 8-year-old neutered female Rhodesian Ridgeback developed acute, nonneurological right pelvic limb lameness. Femoral pulsation was poor, and oscillometric blood pressure measurements between the two pelvic limbs differed markedly. A caudal aortic right external iliac embolus was detected sonographically. Radiographically, there was a caudal esophageal mass and thoracic vertebral spondylitis typical of spirocercosis. Using CT-angiography, a caudal thoracic aortic aneurysm with a mural thrombus was detected. The dog recovered following heparin and aspirin therapy but signs recurred 7 months later. Subsequently, the patient improved on treatment and remains asymptomatic. This report illustrates the value of CT-angiography in detecting aortic thrombosis in dogs with spirocercosis. 相似文献

Objective: To review the thrombolytic agents most commonly used in humans, their mechanisms of action, potential uses, adverse effects, and reports of their use in dogs and cats.
Human data synthesis: Thrombolytic agents avaliable in human medicine include streptokinase, urokinase, tissueplasminogen activator (t-PA), single-chain urokinase plasma activator (scu-PA) and anisoylated plasminogen-strep-tokinase activator complex (APSAC). These agents were originally used for the management of proximal deep vein thrombosis and severe pulmonary embolism but more recently, use of these drugs has been extended to include the treatment of acute peripheral arterial disease, cerebrovascular disease (stroke) and acute coronary thrombosis. The most predictable side effect associated with the use of thrombolytic therapy is hemorrhage.
Veterinary data synthesis: Clinical experience with thrombolytic agents in small animals is limited to streptokinase and t-PA. It is possible, that as in humans, canine and feline patients with PTE and right ventricular dysfunction may benefit from thrombolytic therapy but there are no veterinary studies to support this theory to date. Successful use of streptokinase has been documented in a small number of canine patients with systemic thromboembolism.63 Thrombolytic therapy is relatively efficacious in cats with aortic thromboemboli but is associated with a high mortality rate. 59,60,64 With regard to use of t-PA in veterinary medicine, the small number of animals treated with varying protocols makes it impossible to provide safe and effective dose recommendations at this time.
Conclusions: Future goals for thrombolytic therapy in veterinary medicine include determination of more specific clinical indications, as well as design of effective protocols that minimize mortality and morbidity. 相似文献

AIM:To explore the hypothesis that initiation of pulmonary hypertension involves the up-regulation of monocyte chemoattractant protein-1 (MCP-1) in acute pulmonary thromboembolism (PTE), and to evaluate the role of p38 mitogen-activated protein kinase (MAPK) in this process. METHODS:One hundred and fifty male SD rats were randomly divided into five groups (n=30): normal control group, solvent control group, acute PTE group, acute PTE plus SB203580 (a p38 MAPK specific inhibitor) pretreatment group and acute PTE plus C1142 (a rodent chimeric monoclonal antibody neutralizing rat MCP-1) pretreatment group. Thirty rats in each group were further divided into 1, 4 and 8 h subgroups (n=10). A rat model of acute PTE was established by infusion of an autologous blood clot into the pulmonary artery through a polyethylene catheter. SB203580 or C1142, dissolved in 1% dimethyl sulfoxide (DMSO), was administered to the animals through caudal vein 1 h prior to the beginning of acute PTE modeling. Rats in normal control group and solvent control group were injected with normal saline and 1% DMSO, respectively. The mean pulmonary artery pressure (MPAP) and the mRNA and protein expression of MCP-1 were measured at each time point. RESULTS:Acute PTE elicited significant increase in MPAP, and up-regulated the expression of MCP-1. Pretreatment with SB203580 or C1142 significantly reduced MPAP, and down-regulated the expression of MCP-1. CONCLUSION:These findings suggest that MCP-1 is involved in the formation of acute PTE-induced pulmonary hypertension, and SB203580 down-regulates the expression of MCP-1 via p38 MAPK signaling pathway, thus attenuating pulmonary hypertension. 相似文献

Massive pulmonary thromboembolism in six horses 总被引:2,自引:0,他引:2

This report involves 6 cases in which medical records and post mortem findings were reviewed leading to the diagnosis of massive pulmonary thromboembolism (MPTE). All horses were mature and MPTE has not been recognised previously as a sequel to generalised systemic illness in mature horses. The clinical data and pathological findings of the cases are reported and the authors conclude that MPTE is an uncommon but important complication of medical and surgical disorders in mature horses. In 3 of the cases, the condition was nonfatal suggesting that some horses having developed PTE survive and the condition may not be recognised in such cases. The incidence of the condition might be higher than supposed. 相似文献
