Septic thrombophlebitis, as a result of invasion from adjacent nonvascular infections, includes conditions such as Lemierre syndrome (internal jugular vein septic thrombophlebitis), pylephlebitis (portal vein septic thrombophlebitis), and septic thrombophlebitis of the dural sinuses and the pelvic veins. All of these conditions are associated with a very high mortality if untreated. Appropriate antibacterial therapy dramatically improves the outcome of these infections and results in a low mortality rate, with the notable exception of septic thrombophlebitis of the dural sinuses. The endovascular nature of these infections results in secondary metastatic disease, including pneumonia, endocarditis, and arthritis due to septic embolization and/or hematogenous bacterial spread. The appropriate diagnosis and management of these infections depends on a high degree of clinical suspicion, the use of imaging studies, and early initiation of empiric antibacterial therapy. In this article, we review the diagnosis and management of septic thrombophlebitis, focusing on Lemierre syndrome, pylephlebitis, and septic thrombophlebitis of the pelvic veins.

In 1865, Armand Trousseau noted that unexpected or migratory thrombophlebitis could be a forewarning of an occult visceral malignancy. An analysis by Sack and colleagues in 1977 extended the term Trousseau's syndrome to include chronic disseminated intravascular coagulopathy associated with microangiopathy, verrucous endocarditis, and arterial emboli in patients with cancer, often occurring with mucin-positive carcinomas. In recent times the term has been ascribed to various clinical situations, ranging all the way from these classic descriptions to any kind of coagulopathy occurring in the setting of any kind of malignancy. These multiple definitions of Trousseau's syndrome are partly the consequence of multiple pathophysiologic mechanisms that apparently contribute to the hypercoagulability associated with cancer. Even the classic syndrome probably represents a spectrum of disorders, ranging from exaggerated fluid-phased thrombosis dependent on prothrombotic agents such as tissue factor to a platelet- and endotheliumum-based selectin-dependent microangiopathy associated with mucin-producing carcinomas, along with thrombin and fibrin production. Also considered here are recent hypotheses about genetic pathways within tumor cells that might trigger these thrombotic phenomena, and the reasons why therapy with heparins of various kinds remain the preferred treatment, probably because of their salutary actions on several of the proposed pathologic mechanisms.

We describe the development of nonsusceptibility to daptomycin and vancomycin during treatment for methicillin-resistant Staphylococcus aureus (MRSA) bacteremia associated with infective endocarditis and probable septic thrombophlebitis in a uremic patient. MRSA bacteremia persisted during glycopeptide and subsequent daptomycin treatment but cleared after 5 days' treatment with linezolid and fusidic acid.

We report four adult patients who presented with septic pulmonary emboli and community-acquired methicillin-resistant Staphylococcus aureus bacteremia associated with deep tissue infections, such as pyomyositis, osteomyelitis, and prostatic abscess. The patients lacked evidence of right-sided endocarditis or thrombophlebitis. This association, previously described in children, may also be important in adults.

Septic embolism is a rare disorder associated with infective endocarditis, urinary tract infections, bone infections, femoral thrombophlebitis and sinusitis. We present a 53-year-old patient with multiple systemic embolism and cerebral infarction resulting from aortal thrombus after surgical treatment of the right fibular malleolar fracture with osteosynthetic material placement. After the surgery, the patient became antisocial, with decreased appetite and substantial weight loss. Computerized tomography scan showed several small hypodense zones in the supratentorial and periventricular region of the brain as well as bilateral pleural effusion, large infarcts of the spleen and right kidney, smaller infarcts of the lower pole of the right kidney, discontinuity of the wall of the thoraco-abdominal aorta and a thrombus present in the distal part of abdominal aorta. The findings primarily indicated septic emboli. The right ankle x-ray showed still present postoperative fracture gap of the right fibular malleolus with reduced bone mineralization but no signs of bone destruction. Control MSCT of the abdomen showed a large spleen abscess of 10x6 cm in size. Due to edema of the right ankle, ultrasonography was performed to reveal a thick content in the joint. The patient was transferred to University Department of Surgery, where splenectomy with evacuation of the perisplenic abscess together with extraction of the osteosynthetic material of the right fibular malleolus was performed. If not promptly diagnosed, septic emboli can cause devastating neurologic damage. In our patient, early diagnosis and intensive physical therapy facilitated almost complete regression of his neurologic deficit.

Kodamaea (Pichia) ohmeri is an unusual yeast-form fungus that has recently been identified as an important etiology of fungemia, endocarditis, cellulitis, funguria and peritonitis in immunocompromised patients. We report a case of K. ohmeri fungemia in a 34-year-old hospitalized patient with thrombophlebitis. The patient was admitted to the hospital for evaluation and management of an acquired tracheo-esophageal fistula secondary to an impacted denture. Fever developed on hospital day 22, and physical exam revealed right arm superficial thrombophlebitis at the site of the peripheral venous catheter that was confirmed by Doppler ultrasound. The peripheral vein was removed and blood cultures from hospital day 22 and 23 grew yeast species. The yeast was subsequently identified to be K. ohmeri by Vitek II and API20C and was confirmed by 18S rRNA gene sequencing. The fungemia and right arm phlebitis was successfully treated with a 2-week course of micafungin therapy. This is the first case of K. ohmeri fungemia in a patient that was successfully treated with micafungin.

In rare instances, stroke may precede a diagnosis of cancer and be the first clinical evidence of an underlying malignancy.Cerebral infarction mostly complicates lymphomas, carcinomas, and solid tumors. Malignancy-related thromboembolism can present as acute cerebral infarction, nonbacterial thrombotic endocarditis and migratory thrombophlebitis. It is generally attributed to a cancer-related hypercoagulable period, chronic disseminated intravascular coagulopathy (DIC), or tumor embolism. We reported a case of malignancy-related thromboembolism from an undiagnosed pancreatic adenocarcinoma in a 54-year-old man, who presented with recurrent ischemic stroke due to chronic DIC. He died of the underlying malignancy despite the appropriate institution of anticoagulation therapy.This case emphasizes that cerebral infarction may be the first manifestation of an undiagnosed cancer. If there is laboratory or clinical evidence associated with DIC, patients with a cerebral infarct of an unknown etiology should be investigated for a malignant process. The optimal method of anticoagulation in cancer patients with thromboembolic disease (TED) remains unclear.

Vascular infections present in a multitude of ways with computed tomography (CT) aiding in the diagnosis of many of the uncommon vascular infections, which are equally dangerous and carry severe life-threatening consequences if untreated from a delay in diagnosis. This pictorial review aims to discuss and illustrate the CT findings of the following vascular infections including aortitis, mycotic aneurysms, infective endocarditis, septic thrombophlebitis in the chest and abdomen, and Kawasaki disease. Recognition and prompt diagnosis of these uncommon vascular infections are critical to the initiation of the appropriate management and therapy.

Catheters are the leading source of bloodstream infections in critically ill patients. Because the clinical signs of infection are nonspecific, such infections are overly suspected, which results in unnecessary removal of catheters. A conservative approach might be attempted in mild infections, whereas catheters should always be removed in cases of severe sepsis or septic shock. Nowadays, comprehensive unit-based improvement programs are effective to reduce catheter-related bloodstream infections (CR-BSIs). Rates of CR-BSI higher than 2 per 1000 catheter-days are no longer acceptable. A locally adapted checklist of preventive measures should include cutaneous antisepsis with alcoholic preparation, maximal barrier precaution, strict policy of catheter maintenance, and ablation of useless catheters. Antiseptic dressings and, to a lesser extent, antimicrobial-coated catheters, might be added to the prevention strategies if the level of infections remains high despite implementation of a prevention program. In the case of CR-BSI in intensive care units (ICUs), the catheter should be removed. In the case of persistence of fever or positive blood cultures after 3 days, inadequate antibiotic therapy, endocarditis, or thrombophlebitis should be ruled out.

Hypercoagulability occurs in 15% of patients with malignancy and represents a clinical spectrum ranging from abnormal coagulation tests but no clinically evident thromboembolic disease, to arterial and venous thrombosis, migratory thrombophlebitis, nonbacterial thrombotic endocarditis (NBTE) and disseminated intravascular coagulation. The combination of increased procoagulant activity and decreased fibrinolytic activity accelerates the prothrombotic potential of endothelial cells in malignancy. NBTE is a rare manifestation of cancer-induced hypercoagulability and is commonly seen with mucin-producing adenocarcinomas, but rarely seen with ovarian clear cell carcinoma (OCCC). Cerebrovascular embolization ranges from 14-91% in NBTE. We report a rare case of a 62-year-old female presenting with occipital stroke as a consequence of NBTE in OCCC. Association of NBTE in OCCC has only been reported in 2 cases so far, but presentation with stroke has never been reported in the literature.
