Intravenous extension occurs in many patients with renal cell carcinoma. Preoperative recognition is essential as venous involvement
alters the surgical approach and clinical staging of the tumors. The venous extension of tumor has a characteristic arteriographic
appearance, the recognition of which should prompt venacavography. Computerized body tomography (CBT) may also detect renal
vein and caval extension and provide evidence of early ascites from the Budd Chiari syndrome associated with hepatic vein
obstruction from intracaval tumor extension. However, it may be difficult to distinguish intracaval blood clot and tumor on
the basis of CBT criteria alone. Of the four patients with intracaval growth of renal cell carcinoma, three received preoperative
therapeutic tumor embolization, a procedure that carried no additional risk of tumor detachment and embolization. 相似文献

A practical, ready-to-use preparation of activated charcoal (AZU mixture) for application in toxicology has been formulated. Tb establish its efficacy, the formulation was testedin vitro and in dogs. Thein vitro adsorption capacity was compared to that of freshly prepared charcoal suspension in water (CW) and to Carbomix®. Langmuir adsorption coefficients demonstrated small but clinically insignificant differences in adsorption capacity between the preparations. The laxative sodium sulfate did not reduce the adsorption capacity of charcoalin vitro. Dogs were given 60 mg of paracetamol per kg as an oral solution followed by 5 g of activated charcoal preparation. The area under the plasma concentration versus time curve (control 2955±353 mg·min–1·1–1) was significantly reduced following CW (921±453) and AZU (786±270). The premixed AZU charcoal formulation is efficacious, inexpensive and overcomes the problems of bed-side preparation. An isolated vascularly perfused rat small intestine can be used to describe the effect of activated charcoal on the intestinal secretion of theophylline. 相似文献

Selected benign biliary strictures can be treated safely and successfully by percutaneous balloon dilatation. Primary biliary strictures appear to be less responsive to balloon dilatation alone and require stenting with large catheters (16-20 F) for several months to permit scarring around the catheter. A long period of healing around such a large-bore stent is crucial to the success of such treatment. The most important physiologic indicators for successful dilatation are a long period of stricture challenge with a catheter placed proximal to the dilated segment to allow bile to drain internally across the previously strictured segment, and a near anatomic result as demonstrated by cholangiogram. 相似文献

Percutaneous transhepatic cholangiography and biliary drainage were performed in 12 patients with major injuries to the bile ducts manifested by biliary leaks and fistulas. Eleven of the 12 patients had had inadvertent biliary trauma during surgery. In six patients, the biliary leaks sealed with percutaneous drainage. In other patients requiring definitive surgical procedures on the biliary tract, initial percutaneous drainage allowed these procedures to be delayed until the patients' clinical condition improved. Percutaneous biliary drainage is an important adjunct to the management of patients with traumatic extravasation of bile into the peritoneal cavity or biliary-cutaneous fistula. 相似文献

The impact of bladder removal and urinary diversion for patients' everyday life is largely unknown. The aims of this study
were to compare subjective morbidity of ileal neobladder to the urethra versus ileal conduit urinary diversion and to elucidate
its influence on quality of life. A total of 102 patients who underwent cystectomy due to a bladder malignancy were included
in the study. In 69 patients (67.6%) an orthotopic neobladder and in 33 patients (32.4%) an ileal conduit was performed as
urinary diversion. The compliance was 99% and mean follow-up was 37 months. All patients completed two retrospective quality
of life questionnaires, namely the QLQ-C30 and a questionnaire developed at our institution to ask for urinary diversion specific
items. The questioning and assessment was performed by non-urologists. The results obtained from the validated (QLQ-C30) and
our own specially compiled questionnaire clearly demonstrate that patients with an orthotopic neobladder are more able to
adapt to the new situation than patients with an ileal conduit. In addition, neobladder to the urethra improves the quality
of life because it improves self-confidence, causes better rehabilitation as well as the restoration of leisure, professional,
travelling, and social activities, and reduced risk of inadvertent loss of urine. For example, 92.8% of neobladder patients
did not feel handicapped at all, and 87% did not feel sick or ill, in contrast to 51.5% and 66.7% of ileal conduit patients,
respectively. Of the neobladder patients, 74.6% felt absolutely safe with the urinary diversion in contrast to 33.3% in the
ileal conduit group. Only 1.5% of neobladder patients had wet clothes caused by urine leakage during the day, versus 48.5%
of ileal conduit patients. Moreover, 97% of our neobladder patients would recommend the same urinary diversion to a friend
suffering from the same disease, but only 36% of ileal conduit patients would do so. These results demonstrate that the quality
of life is preserved to a higher degree after orthotopic neobladder than after ileal conduit urinary diversion. 相似文献

Cardiac allograft vasculopathy (CAV) is an accelerated form of coronary artery disease that affects long-term outcomes in heart transplant (HTx) patients. We prospectively evaluated the feasibility of coronary computed tomography angiography (CCTA) for the detection of CAV during clinical implementation at our center. All consecutive HTx patients >4 years post-transplant were actively converted from myocardial perfusion imaging to CCTA for the annual assessment of CAV. Between February 2018 and May 2019, 129/172 (75%) HTx patients underwent a CCTA. Renal impairment (n = 21/43) was the most frequent reason for patients could not undergo CCTA. CCTA image quality was good–excellent in 118/129 (92%) patients, and the radiation dose was 2.1 (1.6–2.8) mSv. CCTA showed obstructive CAV in 19/129 (15%) patients. Thirteen (10%) patients underwent additional tests, of which 8 patients underwent coronary revascularization within 90 days of CCTA. After 1 year, 3 additional coronary angiograms were performed, resulting in one revascularization in a patient with known severe CAV who developed ventricular tachycardia. One myocardial infarction after coronary stenting and 2 non-cardiac deaths were observed. CCTA can be successfully implemented for routine detection of CAV with good image quality and low radiation dose. CCTA allows CAV evaluation with the limited need for additional invasive testing. 相似文献

BackgroundHaglund syndrom is characterized as a painful posterosuperior deformity of the heel with possible causes as tight Achilles tendon, high-arched foot and tendency to walk on the outside of the heel. Surgical treatment may be recommended in cases where of insufficient response to nonoperative treatment. This study aims to evaluate the clinical and radiographic results of central Achilles tendon splitting and double-row suture anchor technique in the surgical treatment of patients with Haglund syndrome.Methods27 patients with Haglund syndrome who underwent central Achilles tendon splitting and double-row suture anchor were retrospectively evaluated. The results were evaluated by the pre- and post-operative American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale and visual analogue scale (VAS). All patients were evaluated radiographically to assess lateral talus-first metatarsal angle (TMTA), Calcaneal pitch angle (CPA), and the Fowler-Philip angle (FPA) preoperatively and postoperatively.ResultsThe mean preoperative AOFAS score was 47 ± 7 points; at the end of the follow-up period, it increased to 92 ± 4 points (p < 0.001). The mean preoperative VAS score was 9 ± 0.9 points; at the end of the follow-up period, it was 2 ± 0.6 points (p < 0.001). The lateral TMTA (preoperative: 5° ± 2°; follow-up: 4° ± 2°; p < 0.001), CPA (preoperative: 21° ± 5°; follow-up: 20° ± 5°; p = 0.005) and FPA (preoperative: 55° ± 6°; follow-up: 32° ± 3°; p < 0.001) values decreased at the end of the follow-up period.ConclusionIn the absence of an improvement to nonoperative treatment methods, central Achilles tendon-splitting approach appears to be an effective and safe treatment option.Level of evidenceLevel IV, retrospective case series. 相似文献
