RESUMEN
PURPOSE: To compare the impact of proximal or distal splenic artery embolisation versus that of splenectomy on splenic immune function as measured by IgM memory B cell levels. MATERIALS AND METHODS: Patients with splenic trauma who were treated by splenic artery embolisation (SAE) were enrolled. After 6 months splenic volume was assessed by CT, and IgM memory B cells in peripheral blood were measured and compared to a local normal reference population and to a post-splenectomy population. RESULTS: Of the 71 patients who underwent embolisation, 38 underwent proximal embolisation, 11 underwent distal embolisation, 22 patients were excluded, 1 had both proximal and distal embolisation, 5 did not survive and 16 did not return for evaluation. There was a significant difference between splenectomy and proximal or distal embolisation and a trend towards greater preservation of IgM memory B cell number in those with distal embolisation-a difference that could not be attributed to differences in age, grade of injury or residual splenic volume. CONCLUSION: IgM memory B cell levels are significantly higher in those treated with SAE compared to splenectomy. Our data provide evidence that splenic embolisation should reduce immunological complications of spleen trauma and suggest that distal embolisation may maintain better function.

The aim of this study was to evaluate our experience with the retrievable Cook Celect inferior vena cava (IVC) filter (William Cook, Europe) with regard to insertion, efficiency, ease of retrieval, and any associated complications. A retrospective review was performed of 115 patients (41 female, 74 male, mean age 47.97 years) who underwent Cook Celect IVC filter insertion between December 2005 and October 2007. Filter insertion was successful in all patients. Of the 115 filters inserted, 57 have been successfully retrieved (49.6%) to date. The successful retrieval rate from attempted retrieval was 93.4%. The mean dwell time of successfully retrieved filters was 114.9 days (range 14-267 days). Failed retrievals were due to a thrombosed vena cava (n = 1) and endothelialisation of the filter (n = 3). In the failed retrieval group the mean implantation time was 142 days (range 78-211 days). While this is the first retrospective clinical study on the Cook Celect filter, results to date are promising. We demonstrated an efficacious filter with a high successful retrieval rate of 93.4% and a low complication rate. The filter was assessed with extended dwell times (range 14-267 days). Failed retrieval secondary to hook endothelialisation continues to be an issue with this filter. We recognize that a limitation of our study was the lack of systematic follow-up for clinically silent complications. Further studies to evaluate longer term outcomes and effectiveness of this filter are warranted.

Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

The aim of our study was to assess our experience with the retrievable Gunther Tulip (GT) inferior vena cava (IVC) filter, with regard to its insertion, efficacy, ease of placement and retrieval, and associated complications. Between November 2001 and October 2005, 322 GT filters were placed in 317 patients. Insertion indications included the following: pulmonary embolus (PE) prophylaxis in trauma patients (n = 232), PE prophylaxis in perioperative patients (n = 27), PE prophylaxis in moribund intensive care unit patients (n = 22), recent PE (n = 48), extensive deep venous thrombosis (n = 66), contraindication to anticoagulation (n = 63), anticoagulation complication (n = 8) and deep venous thrombosis with failed anticoagulation (n = 8). Some patients had more than one indication for caval filter placement. Two hundred and five attempted retrievals have been carried out, with 15 failures. Our successful retrieval rate is 92%. Nineteen filters were originally inserted permanently. There have been three minor complications associated with insertion and five with retrieval. The mean time from filter insertion to attempted retrieval was 76.95 days. The ideal filter implantation time gives the patient the benefit of PE protection, while avoiding the long-term risks associated with caval filters. Although GT retrieval times have lengthened considerably, our data suggest that this is at the expense of successful retrieval rates.

Traumatic vascular injuries involving the extremity are rare and penetrating trauma accounts for the majority of such injuries. The remaining arterial injuries are as a result of either blunt or iatrogenic injuries. The rapid detection, localisation and characterisation of vascular injuries in patients who have a traumatic extremity injury is essential for the effective management and treatment of such injuries. This review will discuss the expanding role of multi-detector computed tomography angiography in diagnosing vascular injuries and its implications on conventional diagnostic angiography. The roles of other non-invasive imaging modalities are reviewed. The presentation and types of vascular injuries in blunt and penetrating injuries are discussed. While surgery remains the gold standard in the management of vascular extremity injuries it has significant morbidity rates. Endovascular techniques are increasingly being used for the treatment of vascular traumatic injuries and various techniques including balloon occlusion, embolisation and stent/stent graft placement are discussed.

Establishing and maintaining venous access forms an increasing proportion of the workload in interventional radiology. Several patient groups require medium-term to long-term venous catheters for a variety of purposes, including chemotherapy, long-term antimicrobials, parenteral nutrition, short-term access for haemodialysis or exhausted haemodialysis. Often, these catheters are required for treatment and frequent blood testing, which can quickly exhaust the peripheral veins. Long-term venous access devices minimize the discomfort of frequent cannulation while preserving the peripheral veins. Venous access devices include implantable catheters (ports), tunnelled catheters and peripherally inserted central catheters, which have different functions, advantages and limitations. Imaging-guided placement is the preferred method of insertion in many institutions because of higher success rates and radiologists are well suited to address catheter complications.

PURPOSE: The primary aim of this prospective pilot study was to determine if the administration of intravenous secretin prior to contrast-enhanced computed tomography (CT) improves pancreatic enhancement and pancreatic tumor conspicuity. The second aim was to determine the optimal timing for secretin administration prior to contrast-enhanced CT. METHODS: Local ethics committee approval was obtained. 35 patients (18 men, 17 women; mean age, 67.6 years; age range; 25 to 86 years) with known or suspected pancreatic malignancy or an abdominal malignancy underwent a helical CT of the pancreas. The pancreas was first localised on an unenhanced scan using 10mm sections. Following 120 ml of intravenous 300 mg/ml of non ionic contrast medium (CM), injected at a rate of 5 ml/s, images of the pancreas (3mm slice thickness) and liver (8mm slice thickness) were obtained at 40 and 70 seconds respectively. A second CT was obtained 1-5 days after the first one using the same CT and intravenous contrast medium injection parameters. However 100 IU of secretin was given as an intravenous bolus between 0 and 5 min prior to intravenous contrast medium administration. Each patient acted as their own control. The attenuation in Hounsfield Units (HU) was recorded on non-contrast, pancreatic phase and portal venous phases for both secretin and non-secretin CTs, in the pancreas and pancreatic tumors (where present). Tumor conspicuity was calculated (in the 19 patients with pancreatic adenocarcinomas) by subtracting pancreatic tumor attenuation from pancreatic attenuation. Statistical evaluation comparing pre and post secretin enhancement was performed using matched paired t-tests. RESULTS: A significant increase in pancreatic enhancement was observed when secretin was injected at 2 to 3 min before contrast material injection (the increase in pancreatic density following secretin at 2 min was 31.5+/-10 HU (29.2%) (p=.035); and at 3 min was 23.2+/-7.8 HU (22.7%) (p=.041). Pancreatic tumor conspicuity in the pancreatic phase was most marked when secretin was injected between 2 to 4 min before contrast medium, with 4 min showing a statistically significant increase in tumor conspicuity, 48.2+/-14.2 HU (p=.04). CONCLUSION: Imaging in the pancreatic phase 2 to 4 min after administration of intravenous secretin leads to greater enhancement of the pancreas with greater tumor conspicuity, than imaging without secretin.

Spontaneous nonhemophiliac hemarthrosis is an unusual entity, which has been little described. We present three cases of spontaneous recurrent hemarthrosis post total knee replacement (TKR) and successful management with embolization. Three male patients were referred to our service for angiography and treatment of recurrent hemarthrosis post TKR. In all three patients antegrade ipsilateral common femoral artery punctures and selective angiography of the geniculate branches were performed with a microcatheter. Abnormal vasculature was noted in all cases. Subsequent embolization was performed with Contour (Boston Scientific, Target Vascular, Cork, Ireland) embolization particles (150-250 and 250-355 microm) in two patients and microcoils in the third (TornadoR; Cook Inc., Bloomington, IN, USA). Technical success was 100%. One patient had a recurrence of symptoms requiring a repeat procedure 6 months later. No complications were encountered. Selective angiography and particle embolization is an effective technique for management of this unusual but problematic postoperative sequelae.

Carotid occlusion is a therapeutic intervention for specific intracranial vascular conditions, including giant, traumatic and intracavernous aneurysms. The long-term complications include de novo aneurysm formation at a distant site due to hemodynamic changes in the circle of Willis. The time frame for de novo aneurysm formation has been described in years with a mean of 9.6 years. There is no formalised radiological surveillance program following carotid occlusion. We describe the rapid development of a de novo posterior communicating artery aneurysm following contralateral carotid occlusion for a traumatic intracavernous aneurysm and suggest the need for a formalised radiological follow-up program following carotid occlusion.

To evaluate the safety and efficacy of percutaneous antegrade ureteric stent removal using a rigid alligator forceps. Twenty patients were included in our study. Indications for ureteric stent insertion included stone disease (n = 7), malignancy (n = 8) and transplant anastomotic strictures (n = 5). Stent retrieval was carried out for proximal stent placement/migration in seven patients and encrustation in the remaining 13. Twenty-two stents were successfully retrieved in 20 patients. There was one technical failure (5%). There were no major complications. We had four minor complications, which included nephrostomy site pain (n = 2), periprocedural sepsis (n = 1) and a small urinoma (n = 1). All patients settled with conservative management. Percutaneous radiologically guided antegrade ureteric stent removal with an alligator forceps is safe and effective, particularly when initial surgical removal has failed.

Creating a direct intrahepatic portocaval shunt (DIPS) is a procedure similar to a transjugular intrahepatic portosystemic shunt (TIPS) in patients for whom the latter is not appropriate due to unsuitable hepato-venous and porto-venous anatomy. We present a patient for whom TIPS was not possible, and DIPS successful.

The provision of enteral nutrition through the placement of gastrostomy/gastrojejunostomy tubes is a well-established procedure. Traditionally, these catheters have been placed either surgically or endoscopically; however, over the past two decades interventional radiologists have increasingly performed these procedures successfully. The perceived advantages of this route lie in the reported lower morbidity and mortality rates. In addition, percutaneous radiologically guided (PRG) catheters may be placed in certain subgroups of patients in whom it would be technically difficult or impossible by other routes, e.g., patients with head and neck or oesophageal tumours. The aim of this review is to describe the techniques of radiologically placed gastrostomy/gastrojejunostomy, discuss its indications and contraindications, describe any associated potential complications and compare PRG results with the more established techniques of open surgical and endoscopic placement. We also describe some recent procedural and catheter modifications.

PURPOSE: Official recommendations for obtaining informed consent for interventional radiology procedures are that the patient gives their consent to the operator more than 24 hr prior to the procedure. This has significant implications for interventional radiology practice. The purpose of this study was to identify the proportion of European interventional radiologists who conform to these guidelines. METHODS: A questionnaire was designed consisting of 12 questions on current working practice and opinions regarding informed consent. These questions related to where, when and by whom consent was obtained from the patient. Questions also related to the use of formal consent forms and written patient information leaflets. Respondents were asked whether they felt patients received adequate explanation regarding indications for intervention, the procedure, alternative treatment options and complications. The questionnaire was distributed to 786 European interventional radiologists who were members of interventional societies. The anonymous replies were then entered into a database and analyzed. RESULTS: Two hundred and fifty-four (32.3%) questionnaires were returned. Institutions were classified as academic (56.7%), non-academic (40.5%) or private (2.8%). Depending on the procedure, in a significant proportion of patients consent was obtained in the outpatient department (22%), on the ward (65%) and in the radiology day case ward (25%), but in over half (56%) of patients consent or re-consent was obtained in the interventional suite. Fifty percent of respondents indicated that they obtain consent more than 24 hr before some procedures, in 42.9% consent is obtained on the morning of the procedure and 48.8% indicated that in some patients consent is obtained immediately before the procedure. We found that junior medical staff obtained consent in 58% of cases. Eighty-two percent of respondents do not use specific consent forms and 61% have patient information leaflets. The majority of respondents were satisfied with their level of explanation regarding indications for treatment (69.3%) and the procedure (78.7%). Fifty-nine percent felt patients understood alternative treatment options. Only 37.8% of radiologists document possible complications in the patient's chart. Comments from respondents indicated that there is insufficient time for radiologists to obtain consent in all patients. Suggestions to improve current local policies included developing the role of radiology nursing staff and the use of radiology outpatient clinics. CONCLUSIONS: More than 50% of respondents are unhappy with their policies for obtaining informed consent. Interventional societies have a role to play in advocating formal consent guidelines.

AIM: The objectives of this study were to identify prognostic features for patients with hepatic metastases and unknown primary neoplasms (UPN), determine the common primary tumours, assess the value of diagnostic tests in finding these tumours, and evaluate the impact of therapy and knowledge of the primary tumour on patient survival. MATERIALS AND METHODS: Eighty-eight patients with UPN and liver biopsy proven hepatic metastases over a 10-year period were reviewed (M:F, 58:30; age range 27-91 years, median 64.5 years). Histopathology, diagnostic investigations and success at identifying the primary neoplasm were recorded. In addition, in 70 patients with adenocarcinoma histology (M:F, 48:22; age range 27-91 years, median 65 years), treatment and survival data from the date of biopsy were recorded. RESULTS: The histological spectrum included adenocarcinoma in 70, neuroendocrine in four, squamous cell carcinoma in four, small cell carcinoma in four, carcinoid in two, hepatoma in one and three others. Extensive investigation identified a primary neoplasm in 16/88 patients (18%) including colorectal in six, gastric in two, lung in four, oesophageal in two, prostate in one and carcinoid in one. In the adenocarcinoma group survival data were available for 62/70 patients. Sixteen of 62 patients received active treatment with either surgery, chemotherapy, radiotherapy or a combination protocol. Forty-six of 62 patients received palliative care alone. Median survival for the adenocarcinoma group overall was 49 days. The median survival for treated patients (49 days) versus untreated patients (52 days) was not significantly different (P=0.128). Patients <65 years were more likely to receive active treatment than those >65 years (P=0.006). Age with a hazard ratio (HR) of 1.01 (P=0.178), active treatment (HR=0.65;P=0.194), knowledge of the primary neoplasm (HR=0.60;P=0.213) and male gender (HR=0.88;P=0.642) had no significant effect on survival. CONCLUSION: Although hepatic metastases are associated with poor prognosis, it is essential that a liver biopsy be performed to obtain a histological diagnosis. Adenocarcinoma metastases carry a dismal prognosis, and no prognostic factors, including knowledge of the primary tumour, are significant for patient survival. Extensive investigation is not warranted in patients with adenocarcinoma liver metastases.

States use forms of regulation in small board-and-care homes to control quality; however, quality varies in spite of these efforts. This study of 94 small facilities compared quality of care measures in homes regulated by a state-administered program with those in nonregulated homes. It also compared homes on those variables using average payment for services as the independent variable. Results indicate that higher payments for services had a greater impact on quality than did participation in a regulatory program. Adequate funding may be key to maintaining reasonable quality in these homes.

The numbers of blacklegged tick, Ixodes scapularis Say, per hectare that engorged as larvae and nymphs on white-footed mice, Peromyscus leucopus (Rafinesque), were estimated at 3 sites in coastal Massachusetts. Estimates of numbers of engorged ticks dropping per day from trapped mice were multiplied by mark-recapture estimates of the density (numbers per hectare) of white-footed mice to estimate numbers of ticks engorging on mice per hectare. In 1991, estimates of seasonal totals per hectare of I. scapularis nymphs completing blood meals on P.leucopus ranged from 825 +/- 68 at Nonamesset to 6,654 +/- 770 at Menemsha. This absolute sampling method (the drop-off method) was compared with drag sampling for nymphal ticks. Per hectare estimation of engorgement rates overcomes a shortcoming associated with drag sampling because site-to-site comparisons can be made even where vegetation structure differs markedly among sites. The drop-off method may be used to quantify the contribution of any host to the engorged tick population, provided sufficient such hosts can be collected on a weekly basis.

Information about board-and-care homes reported in the media and in federal committee hearings indicates that they are shoddy and exploitative environments that do not provide adequate care. Research done in board-and-care homes in recent years, however, demonstrates that they can provide adequate care and a satisfying environment for some of the people they serve. Policy at the federal, state, and local levels should be guided by both the need to assure the health and safety of board-and-care residents and the needs of residents and operators identified in scientific studies.

This paper examines the effect of several social and physical environmental features of small unregulated board and care homes on the psychological well-being of elderly residents. Data were collected from operators (N = 177) and residents (N = 285) of board and care homes in five counties in Ohio. The social aspects of the environment such as peer relationships had a more significant impact on resident's psychological well-being than aspects of the physical environment.
