The internal jugular vein is an uncommon site of deep venous thrombosis. Infection, prolonged central venous catheterization, and trauma are the usual causes of this condition. We present an unusual case of spontaneous thrombosis of the internal jugular vein. The evaluation of this case included a search for possible anatomic, hematologic, and oncologic conditions which could predispose to hypercoagulability and thrombosis. Anticoagulation therapy resulted in complete resolution of thrombosis and subsequent recanalization of the internal jugular vein.

Cleavage of crosslinked fibrin by the fibrinolytic enzyme plasmin leads to the formation of fibrin degradation products, among them D-dimers. D-Dimer can easily be measured in plasma or in whole blood by means of monoclonal antibodies directed against epitopes of the D-dimer fragment. Elevated plasma levels of D-dimers are characteristic for patients with venous thromboembolism (DVT, PE), but occur also in patients with infectious diseases, malignant neoplasms and heart failure. Given the high sensitivity of ELISA D-dimer assays with respect to venous thromboembolism it is possible to reliably rule out DVT or PE when the plasma concentration of D-dimer is below the cut-off level. Thus, it is possible to rule out DVT in about 30% of outpatients with suspected venous thromboembolism by the measurement of D-dimer-concentration with a validated assay avoiding further diagnostic procedures.

Infection at the injection site following parenteral drug abuse is a well known complication. In Oslo, Norway's capital city with a population of 500,000, most of these infections are treated on an out-patient basis in the surgical department at Oslo Legevakt, a publicly funded primary health care facility. During the four last months of 1998, 179 patients were admitted with skin and soft tissue infections at the injection site compared to only 46 in the same period in 1993. This suggests that the problem is increasing. In this retrospective study these populations were analysed according to their age, sex, clinical appearance, and the treatment given. In 1998, 36 patients were admitted to hospital, the rest treated on an out-patient basis. A total of 112 patients were treated with simple incision and drainage, 63 of whom were given antibiotics. 37 patients were treated with antibiotics only. There were few complications; two patients with deep venous thrombosis and one in need of skin transplantation. We saw no development of life threatening infections among our patients. The article also gives suggestions for treatment.

Infection, pulmonary embolism caused by mostly deep venous thrombosis (DVT), hypoxaemia and drugs, used in the treatment of chronic obstructive pulmonary disease (COPD), related arrhythmia, aspiration are mostly responsible for acute exacerbations of COPD. The incidences of DVT and pulmonary embolus were investigated in 56 hospitalised cases with acute exacerbation of COPD. DVT was diagnosed in six (10.7%) cases with coloured doppler ultrasonography (CDU) and in two cases whose examinations were not sufficient enough to diagnose or refuse DVT. Diagnosis of pulmonary embolus was investigated with ventilation/perfusion scintigraphy in eight cases of clinically medium--high-probable pulmonary embolus. Pulmonary embolus was determined in five cases (8.9%). Age, weight, height, disease course, pulmonary function tests, arterial blood gases and haematocrit values of the cases did not predict the diagnosis of DVT and pulmonary embolus in our cases.

Infection with human immunodeficiency virus (HIV) may lead to hemostatic imbalances. Forty-nine consecutive patients with acute opportunistic infections were screened for thrombophilic parameters. A follow-up investigation was performed after 10 +/- 8 weeks in 26 patients. In acutely ill patients, the incidence of protein S deficiency was 67% (33/49) and of protein C deficiency 25% (12/49), while at the follow-up visit the incidences were 54% (14/26) and 8% (2/26), respectively. Protein S and protein C levels increased significantly from initial to follow-up visit (p < 0.05). Lupus anticoagulants were not detected and anticardiolipin IgG antibodies were present in 11.4% (5/44). Three patients presented with deep venous thrombosis on admission; in two, protein S or protein C deficiency was observed. In conclusion, an acquired protein S and protein C deficiency often develop in patients with HIV and acute illness; this may be reversible after treatment for opportunistic infections.

Assessing the quality of care delivered in office-based outpatient surgery centers is difficult because formerly there was no central data collection system. The American Association for Accreditation of Ambulatory Surgery Facilities (AAAASF), in its ongoing effort to assess and improve patient care, has developed an Internet-based quality improvement and peer review program to analyze outcomes for surgery centers it accredits. Reporting is mandatory for all surgeons operating in AAAASF-accredited facilities. Each surgeon must report all unanticipated sequelae and at least six random cases reviewed by an accepted peer review group biannually. A total of 411,670 procedures were analyzed during a 2-year period (from 2001 to 2002). There were 2597 sequelae reported during this period. The most common sequela was hematoma formation following breast augmentation. Infection occurred in 388 cases. Deep vein thrombosis, pulmonary embolism, and intraoperative cardiac arrhythmias were found to occur in a frequency consistent with previous reports. Significant complications (hematoma, hypertensive episode, wound infection, sepsis, and hypotension) were infrequent. A total of 1378 significant sequelae were reported for 411,670 procedures. This calculates to one unanticipated sequela in 299 procedures (an incidence of 0.33 percent). Seven deaths were reported. A death occurred in one in 58,810 procedures (0.0017 percent). The overall risk of death was comparable whether the procedure was performed in an AAAASF-accredited office surgery facility or a hospital surgery facility. This study documents an excellent safety record for surgical procedures performed in accredited office surgery facilities by board-certified surgeons.

Deep vein thrombosis and its potentially fatal complication, PE, accounts for more than 250,000 hospitalizations annually in the United States. Pulmonary embolism is the most serious complication and has a 3-month mortality of 17%. Two million people each year are affected by VTE, and the prevalence is rising because of the aging population. Deep vein thrombosis and its potential complication, PE, is preventable. However, there still is widespread failure to screen, diagnose, and initiate prophylactic therapy in patients at risk. This failure can be corrected by development of a heightened awareness of risk factors among emergency department physicians and nurses and by similar personnel caring for bedridden hospitalized patients. A recent landmark study Prophylaxis in Medical Patients With Enoxaparin Study (MEDENOX) revealed the risk factors of VTE in order of frequency: (1) previous VTE, (2) acute infectious disease, (3) cancer, (4) age greater than 75 years, and (5) chronic respiratory disease. This study confirmed the effectiveness of a LMWH, enoxaparin, in the prevention of VTE.

Uterine artery embolization (UAE) is an increasingly performed, minimally invasive alternative to hysterectomy or myomectomy for women with symptomatic uterine fibroids. A growing body of literature documents symptomatic improvement in the majority of women who undergo UAE. Although UAE is usually safe and effective, there are a number of known complications associated with the procedure. Major complications include fibroid passage, infectious disease (endometritis, pelvic inflammatory disease-tubo-ovarian abscess, pyomyoma), deep venous thrombosis, pulmonary embolism, inadvertent embolization of a malignant leiomyosarcoma, ovarian dysfunction, fibroid regrowth, uterine necrosis, and even death. Minor complications include hematoma, urinary tract infection, retention of urine, transient pain, and vessel or nerve injury at the puncture site. As UAE takes its place in the treatment arsenal for women with symptomatic fibroids, radiologists need to be familiar with UAE-associated complications, which may require further treatment and may even be life threatening in some cases. Knowledge of these complications and their imaging features should lead to prompt diagnosis and appropriate treatment.

Acutely ill general medical patients are at moderate-to-high risk of venous thromboembolism (VTE); approximately 10-30% may develop deep vein thrombosis or pulmonary embolism, the latter being a leading contributor to deaths in hospital. Medical conditions associated with a high risk of VTE include cardiac disease, cancer, respiratory disease, inflammatory bowel disease, and infectious disease. Predisposing risk factors for VTE in medical patients include history of VTE, history of malignancy, complicating infections, increasing age, thrombophilia, prolonged immobility, and obesity. Unfractionated heparin (UFH), low-molecular weight heparin (LMWH), and fondaparinux sodium have been shown to be effective agents in the prevention of VTE in medical patients. In this setting, UFH has a higher rate of bleeding complications than LMWH. There is no evidence supporting the use of aspirin, warfarin, or mechanical methods to prevent VTE in medical patients. We recommend either LMWH or fondaparinux sodium as well tolerated and effective thromboprophylactic agents in medical patients.
