    Successful Urgent Transplantation of an Adult Kidney into a Child with Inferior Vena Cava Thrombosis

    AMERICAN JOURNAL OF TRANSPLANTATION, Issue 8 2009
    R. B. Stevens
    Poor venous drainage options following inferior vena cava (IVC) thrombosis have been considered to complicate or preclude renal transplantation of adult kidneys into pediatric patients. We describe urgent renal transplantation in a 5-year-old (15.3 kg) male with IVC thrombosis using an adult living donor. Preoperative magnetic resonance venography revealed a patent infrahepatic/suprarenal vena cava and portal system. In surgery, the right liver lobe was mobilized sufficiently to anastomose the graft renal vein to the native IVC at the confluence of the native left renal vein and proximal vena cava. Graft function has remained excellent with serum creatinine of 0.5 mg/dL at 36 months. IVC thrombosis need not preclude successful transplantation of adult-sized kidneys into children. [source]

    Effects of factor XI deficiency on ferric chloride-induced vena cava thrombosis in mice

    JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 9 2006

    Summary.,Background:,Increased plasma levels of coagulation factor (F) XI are a risk factor for venous thrombosis. Objective:,To further explore the relationship between FXI and venous thrombosis, we evaluated FXI-deficient and wild-type mice in a ferric chloride (FeCl3)-induced vena cava thrombosis model. Methods and Results:,Thrombosis was induced by 3-min topical application of filter papers containing increasing concentrations of FeCl3 and the thrombus was measured at 30 min. In contrast to wild-type mice, FXI-deficient mice failed to form a thrombus with 5% FeCl3, and were partially protected against 7.5% and 10% FeCl3, respectively. The protective effect was substantially stronger than a high dose of heparin (1000 units kg,1, i.v.), clopidogrel (30 mg kg,1, p.o.) or argatroban (30 mg kg,1, i.p.). These antithrombotic agents resulted in off-scale bleeding in a tail bleeding time assay, whereas the bleeding time of FXI-deficient mice was unchanged compared to wild-type mice. In addition to its known effect on the coagulation cascade, enhanced clot lysis was demonstrated in FXI-deficient mouse and human plasma compared to those supplemented with FXIa. Conclusion:,Given the strong antithrombotic efficacy (possibly contributed by strong anticoagulant activity associated with increased fibrinolytic activity) and mild bleeding diathesis associated with FXI deficiency, therapeutic inhibition of FXI may be a reasonable therapeutic strategy to treat or prevent venous thrombosis.

    Canine leishmaniasis with nephrotic syndrome and aortic and caudal vena cava thromboembolism

    JOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 5 2008

    Abstract Objective , To describe a case of leishmaniasis associated with nephrotic syndrome and aortic and caudal vena cava thrombosis in a dog. Case Summary , A 3-year-old male Boxer was referred to the Faculty of Veterinary Medicine, Lisbon, with vomiting, polyuria, polydipsia, lethargy, anorexia, and weight loss. On admission, the dog was thin, quiet, and dehydrated. Initial laboratory abnormalities were compatible with a diagnosis of leishmaniasis (confirmed by serology and bone marrow aspirate), and nephrotic syndrome. Three days later, the animal developed lumbar pain, paraparesis, and absent femoral pulses. Coagulation tests showed a marked reduction in antithrombin (AT) and a mild increase in serum fibrinogen concentration. A diagnosis of thromboembolism was made. In spite of treatment aimed at controlling the primary condition and decreasing further thrombus formation, necrosis developed in the distal right pelvic limb and the nail beds of the left pelvic limb. Against medical advice, medication was stopped and, 15 days later, the dog returned to the hospital, showing extensive necrosis of both pelvic limb extremities. Euthanasia was performed at the owner's request. Necropsy showed a thrombus localized at the distal aorta and extending into the right iliac artery, and an additional thrombus extending from both femoral veins onto the caudal vena cava. New or Unique Information Provided , Thromboembolic disease is rare in dogs with leishmaniasis with nephrotic syndrome. This case suggests that a marked decrease in AT and a mild increase in serum fibrinogen may elicit a hypercoagulable state in these patients. [source]

    Pacemaker and Defibrillator Lead Extraction: Predictors of Mortality during Follow-Up

    Background:Extraction of cardiac implantable electric devices is an accepted procedure when systems become infected or malfunction. However, there is an associated morbidity and mortality. We report our 5-year experience and identify predictors of mortality, and long-term follow-up. Methods:We analyzed extraction data from January 2003 to November 2007. Extraction methods used were: locking stylets, telescoping sheaths ± laser, and femoral work stations. Results:One hundred and eighty-three cases were referred, aged 65 ± 16 years (range 28,83); 76% were males. Mean implant time was 75 months (range 4,312 months) and indications were: pocket infection (48%), nonfunctioning lead (22%), erosion through skin (18%), endocarditis/septicemia (11%), bilateral superior vena cava thrombosis (0.5%), and painful lead (0.5%). The number of leads extracted were 369, with complete removal in 90.7% and partial in 7.6%. There were no intraoperative deaths but five (2.7%) died within the same admission as their extraction from overwhelming sepsis. Twelve deaths (6.6%) occurred during an average follow-up of 965 days (range 40,1670). Multivariate logistic regression demonstrated that C-reactive protein preprocedure was predictive of acute in-hospital mortality. Conclusions:Intravascular lead extraction is a safe and efficient method of removing leads. However, there is a subgroup of patients with systemic sepsis with raised inflammatory markers who are at high risk of in-hospital mortality. Long-term follow-up demonstrates mortality which is a marker of the underlying etiology for device implantation, with heart failure patients particularly at risk. (PACE 2010; 33:209,216) [source]
