    Description / Table of Contents: Résumé L'abcès hépatique amibien ou à pyogènes peut être diagnostiqué avec une grande précision soit par l'échographie, soit par la tomodensitométrie. L'échographie est la méthode de choix et détecte presque 100% des abcès. On obtient la confirmation du diagnostic d'abcès amibien par le test d'hémagglutination indirecte qui est positive dans presque 100% des cas. On doit faire des cultures de pus provenan′ de l'abcès et des hémocultures en cas d'abcès à pyogènes du foie. Ces cultures ont été positives dans 90% des cas. L'échographie et la tomodensitométrie aident à guider le drainage de abcès. Dans le traitement de l'abcès amibien du foie, le métronidazole est l'amibicide de choix. Le drainage à ciel ouvert est contreindiqué. Pour les cas qui ne répondent pas aux amibicides, un drainage percutané guidé par la tomodensitométrie ou l'échographie est indiqué. La surinfection d'un abcès amibien du foie est extrêmement rare. L'identification et la détermination de la sensibilité aux antibiotiques des organismes responsables de l'abcès à pyogènes est une étape extrêmement importante. A moins qu'une laparotomie soit nécessaire pour traiter une infection intraabdominale associée ou que le volume de l'abcès soit extrêmement important, le traitement initial d'un abcès à pyogènes comprend 2 semaines d'antibiotiques adaptés par voie générale suivies d'un mois d'antibiotiques par voie orale. La plupart des abcès à pyogènes répondront bien à ce traitement. Si le drainage d'un abcès à pyogènes s'avère nécessaire, la meilleure technique est percutanée avec un cathéter inséré sous contrôle tomodensitométrique ou échographique. On réservera le drainage chirurgical à ciel ouvert aux cas où une laparotomie est nécessaire pour d'autres raisons et où le malade n'a pas répondu à l'antibiothérapie adaptée et chez qui le drainage percutané est impossible à faire. La mortalité de l'abcès amibien traité devrait approcher 0% et atteindre pour l'abcès à pyogènes moins de 10%.
    Abstract: Resumen El absceso hepático—amibiano o piogénico—puede ser diagnositicado con gran precisión mediante la ultrasonografía (US) o la tomografía computadorizada (TC). La ultrasonografía es la modalidad de escogencia; détecta casí el 100% de los abscesos. La confirmación del diagnóstico de absceso amibiano del hígado se hace por la prueba de hemaglutinación indirecta, la cual debe resultar positiva en prácticamente el 100% de los casos. Cultivos del pus y de la sangre deben ser realizados en los pacientes con abscesos piógenos. Se logran cultivos positivos del pus del absceso en 90% de los casos. Se utiliza la guía ultrasonográfica o de tomografía computadorizada para la aspiración del absceso. El metronidazol es el agente amebicida de preferencia en el tratamiento del absceso amibiano del hígado. El drenaje abierto está contraindicado. En los casos en que falla la terapia con amibicidos, se realiza el drenaje cerrado guiado por US o por TC. La infección secundaria de un absceso amibiano del hígado es un fenómeno extraordinariamente raro. La identificatión y determinatión de la sensibilidad antibiótica de los microorganismos responsables del absceso piógeno representa un paso crucial en su manejo. A menos que se haga necesario realizar una laparotomía para la correción del algún proceso intraabdominal o porque el absceso es excesivamente grande, el tratamiento inicial del absceso piógeno es un ciclo de antibióticos propiados de 2 semanas, seguidos de tratamiento con antibióticos orales por un mes. La mayoría de los abscesos piógenos del hígado responde a este tipo de tratamiento. Si se requiere drenaje de un absceso piógeno, la técnica de preferencia es la punción percutánea por medio de un catéter guiado por US o TC. El drenaje quirúrgico abierto debe reservarse para aquellos casos en que la laparatomía es necesaria por razones diferentes o en que hay falla en la respuesta a un ciclo de terapia antibiótica adecuada y el drenaje percutáneo no es factible. La mortalidad en el manejo del absceso amibiano del hígado debe ser nula, y para el absceso piógeno de menos de 10%.
    Notes: Abstract Hepatic abscess—amebic or pyogenic—can be diagnosed with great accuracy by either ultrasonography or computed tomographic (CT) scanning. Ultrasound is the modality of choice and will detect almost 100% of abscesses. Confirmation of a diagnosis of amebic liver abscess is made by the indirect hemagglutination test that should be positive in almost 100% of cases. Cultures of pus from the abscess and from the blood must be obtained in cases of pyogenic liver abscess. A positive culture of pus from the abscess has been achieved in 90% of cases. Ultrasound or CT guidance is utilized in aspiration of a hepatic abscess. In the treatment of an amebic liver abscess, metronidazole is the amebicide of choice. Open drainage is contraindicated. For cases that fail to respond to therapy with amebicides, closed drainage guided by CT or ultrasound is performed. Secondary bacterial infection of an amebic liver abscess is an extremely rare event. The identification and determination of the antibiotic sensitivity of organisms responsible for pyogenic liver abscess is a crucially important step. Unless a celiotomy is necessary to correct an intraabdominal process or the abscess is extremely large, the initial treatment of pyogenic liver abscess is a 2 week course of appropriate antibiotics followed by a 1 month course of oral antibiotics. The majority of pyogenic liver abscesses will respond to such treatment. If drainage of a pyogenic abscess is required, the preferable technique is with a percutaneous CT- or ultrasound-directed catheter. Open surgical drainage should be reserved for those cases in which a celiotomy is required for other purposes or for the patient who has failed a course of appropriate antibiotic therapy and closed percutaneous drainage is not feasible. The mortality for treatment of amebic liver abscess should be approximately zero and for pyogenic liver abscess should be less than 10%.

    Notes: Abstract During a 20-year period from 1973 to 1992, 109 patients underwent early operation for acute popliteal artery trauma. Clinical variables were analyzed for their association with amputation. Gunshot wounds accounted for the majority of injuries (73%), followed by shotgun wounds (18%), stab wounds (6%), iatrogenic injuries (2%), and lacerations (1%). Fasciotomies were performed selectively in 41% of patients. Seven patients (6%) lost the injured extremity despite arterial repair. The mean time from injury to arterial repair was not significantly different for patients with or without subsequent amputation (8.6±3.6 and 9.7±7.4 hours, respectively;p=0.69). Delay in diagnosis longer than 6 or 12 hours after the injury did not increase the risk of amputation. Other factors not associated with limb loss were preoperative ischemic neurologic deficit or compartmental hypertension, concomitant fracture, and popliteal vein injury. Severe soft tissue injury (p〈0.0001) or postoperative wound sepsis (p〈0.0001) substantially increased the risk of amputation. Delayed fasciotomies were uncommon (4%) but were associated with a significantly increased risk of amputation (p〈0.0001). Vein grafting for arterial repair (p=0.0017) and shotgun injuries (p〈0.0001) were associated with amputation to the extent that they were related to severe soft tissue injury. The degree of soft tissue trauma and subsequent infection of devitalized tissue limits the success of popliteal arterial repair. Changes in the mechanism of trauma, liberal use of four-compartment fasciotomies, and aggressive management of soft tissue injury resulted in a significant decline in the amputation rate from 21% (4/19) in the first 5 years to 0% (0/39) in the last 5 years of the study.

    Notes: Summary The role of surgical therapy for Takayasu arteritis remains controversial. From 1973–1991, 23 patients with Takayasu arteritis have been treated at the University of Southern California. Twelve patients have required 17 arterial reconstructions for symptomatic complications of arterial disease refractory to medical therapy. Indications for operation have included renovascular hypertension (7), extremity ischemia (5), cerebrovascular insufficiency (2), dilated ascended aorta with aortic insufficiency (1), thoracic aortic aneurysm (1), and abdominal aortic aneurysm (1). Long-term clinical follow-up has demonstrated uniform symptomatic improvement. Fifteen of seventeen arterial reconstructions are still patent. Surgical treatment of symptomatic Takayasu arteritis is highly effective. Excellent long-term graft patency can be expected following arterial reconstruction.

    Notes: Abstract Thrombosis of central veins has become more prevalent because of increased use of long-term central venous catheterization.Candida superinfection of the thrombus can occur particularly in patients on long-term antibiotic therapy and on parenteral nutrition. Removal of the catheter, thrombolytic therapy, anticoagulation, and antifungal therapy with amphotericin B will usually eradicate the candidemia and restore venous patency. Occasionally this therapeutic regimen fails. This case report illustrates such a failure in which multiple pulmonary emboli could have caused death. Surgical thrombectomy of the innominate vein effectively removed the source of theCandida sepsis and maintained patency of a major vein. Thrombectomy should be considered as a therapeutic option in septic central vein thrombosis.
