    Pretreatment radiologic staging can, theoretically, improve the effectiveness and results of surgical treatment in esophageal and gastroesophageal junction carcinoma. Ideally, on these studies it is possible to select only patients with limited local disease for surgery, whereas those with nonresecta.ble tumors or metastases to distant sites are excluded from surgery and submitted to other treatment modalities. The purpose of this study was to evaluate the utility of CT, US and US-guided FNAB for pretreatment staging of esophageal and gastroesophageal junction carcinoma. In assessing distant metastases, these techniques were evaluated at different sites, Because little has been published regarding the examination of supraclavicular lymph nodes in esophageal and gastroesophageal junction carcinoma, a retrospective stndy was first performed to determine the number of patients with squamous cell carcinoma of the intrathoracic esophagus in whom supraclavicular metastases could be demonstrated with us and usguided FNAB (Chapter 2), Subsequently, palpation, CT and US were prospectively evaluated for assessing supraclavicular metastases in patients with either esophageal or gastroesophageal junction carcinoma (Chapter 3). Accuracy of either CT, US, or a combination of both studies, to assess distant metastases in general and at the various sites was determined (Chapter 4). The utility of US-guided FNAB for diagnosing metastases was evaluated (Chapter 5). Assessment of resectability of the primary tnmor was analyzed on CT stndies alone because, generally, this cannot be displayed on US stndies (Chapter 6). Finally a survival analysis was performed to estimate the influence on survival of distant metastases, assessed on US or CT studies, or diagnosed by means of US-guided FNAB and cytologic stndy (Chapter 7)

    BACKGROUND: Effective and durable options for infrapopliteal artery revascularization for patients with chronic limb-threatening ischemia (CLTI) are limited. METHODS: The SAVAL trial is a prospective, multicenter, randomized trial of patients with CLTI and infrapopliteal artery lesions with total lesion length ⩽ 140 mm, stenosis ⩾ 70%, and Rutherford category 4-5 assigned 2:1 to treatment with the SAVAL self-expandable paclitaxel drug-eluting stent (DES) or percutaneous transluminal angioplasty (PTA) with an uncoated balloon. The primary effectiveness endpoint was primary vessel patency (i.e., core lab-adjudicated duplex ultrasound-based flow at 12 months in the absence of clinically driven target lesion revascularization or surgical bypass of the target lesion). The primary safety endpoint was the 12-month major adverse event (MAE)-free rate; MAEs were defined as a composite of above-ankle index limb amputation, major reintervention, and 30-day mortality. The endpoints were prespecified for superiority (effectiveness) and noninferiority (safety) at a one-sided significance level of 2.5%. RESULTS: A total of 201 patients were enrolled and randomly assigned to treatment ( CONCLUSION: The SAVAL trial did not show benefit related to effectiveness and safety with the nitinol DES compared with PTA in infrapopliteal artery lesions up to 140 mm in length. Continued innovation to provide optimal treatments for CLTI is needed

    Purpose: To evaluate percutaneous cholecystostomy in patients with acute cholecystitis and an increased surgical risk. Methods: Thirty-three patients with acute cholecystitis (calculous, n = 22; acalculous, n = 11) underwent percutaneous cholecystostomy by means of a transhepatic (n = 21) or transperitoneal (n = 12) access route. Clinical and laboratory parameters were retrospectively studied to determine the benefit from cholecystostomy. Results: All procedures were technically successful. Twenty-two (67%) patients improved clinically within 48 hr; showing a significant decrease in body temperature (n = 13), normalization of the white blood cell count (n = 3), or both (n = 6). There were 6 (18%) minor/moderate complications (transhepatic access, n = 3; transperitoneal access, n = 3). Further treatment for patients with calculous cholecystitis was cholecystectomy (n = 9) and percutaneous and endoscopic stone removal (n = 8). Further treatment for patients with acalculous cholecystitis was cholecystectomy (n = 2) and gallbladder ablation (n = 2). There were 4 deaths (12%) either in hospital or within 30 days of drainage; none of the deaths was procedure-related. Conclusions: Percutaneous cholecystostomy is a safe and effective procedure for patients with acute cholecystitis. For most patients with acalculous cholecystitis percutaneous cholecystostomy may be considered a definitive therapy. In calculous disease this treatment is often only temporizing and a definitive surgical, endoscopic, or radiologic treatment becomes necessary

    The goal of this study was to explore possible specific mammographic and sonographic features in women with non-puerperal mastitis (NPM), in order to make an accurate diagnosis and prevent unnecessary surgical procedures. From a group of 93 patients with NPM diagnosed between 1987 and 1992, the mammograms of 41, the sonograms and cytology of 47, and the histology of seven patients were retrospectively reviewed. Follow-up was performed on those without histology. In 20 of the 47 patients the inflammation was located subareolarly. In 50% of those with non-subareolar lesions, mammography showed a circumscribed lesion. Sonographically, all patients had an identifiable lesion either well or poorly defined. The majority of the lesions were cystic, but in 23 of 47 cases solid components were seen. Signs of infection in cystic lesions were observed in 25 of 47 cases. Posterior shadowing was not observed. During the follow-up period no breast malignancy was found. It is concluded that NPM has no specific mammographic or sonographic sign. Diagnosis should be made with additional diagnostic assessment, such as FNAB, which was diagnostic in all cases

    Ruptured Internal Iliac Artery Aneurysm: Staged Emergency Endovascular Treatment in the Interventional Radiology Suite

    Ruptured aneurysms of the internal iliac artery (IIA) are rare and challenging to treat surgically. Due to their anatomic location they are difficult to operate on and perioperative morbidity is high. An endovascular approach can be helpful. We recently treated a patient with a ruptured IIA aneurysm in the interventional radiology suite with embolization of the side-branch of the IIA and placement of a covered stent in the ipsilateral common and external iliac arteries. A suitable stent-graft was not available initially and had to be brought in from elsewhere. An angioplasty balloon was temporarily placed across the ostium of the IIA to obtain hemostasis. Two hours later, the procedure was finished by placing the stent-graft

    Nationwide Study to Predict Colonic Ischemia after Abdominal Aortic Aneurysm Repair in The Netherlands

    BACKGROUND: Colonic ischemia remains a severe complication after abdominal aortic aneurysm (AAA) repair and is associated with a high mortality. With open repair being one of the main risk factors of colonic ischemia, deciding between endovascular or open aneurysm repair should be based on tailor-made medicine. This study aims to identify high-risk patients of colonic ischemia, a risk that can be taken into account while deciding on AAA treatment strategy.METHODS: A nationwide population-based cohort study of 9,433 patients who underwent an AAA operation between 2014 and 2016 was conducted. Potential risk factors were determined by reviewing prior studies and univariate analysis. With logistic regression analysis, independent predictors of intestinal ischemia were established. These variables were used to form a prediction model.RESULTS: Intestinal ischemia occurred in 267 patients (2.8%). Occurrence of intestinal ischemia was seen significantly more in open repair versus endovascular aneurysm repair (7.6% vs. 0.9%; P &lt; 0.001). This difference remained significant after stratification by urgency of the procedure, in both intact open (4.2% vs. 0.4%; P &lt; 0.001) and ruptured open repair (15.0% vs. 6.2%); P &lt; 0.001). Rupture of the AAA was the most important predictor of developing intestinal ischemia (odds ratio [OR], 5.9, 95% confidence interval [CI] 4.4-8.0), followed by having a suprarenal AAA (OR 3.4; CI 1.1-10.6). Associated procedural factors were open repair (OR 2.8; 95% CI 1.9-4.2), blood loss &gt;1L (OR 3.6; 95% CI 1.7-7.5), and prolonged operating time (OR 2.0; 95% CI 1.4-2.8). Patient characteristics included having peripheral arterial disease (OR 2.4; 95% CI 1.3-4.4), female gender (OR 1.7; 95% CI 1.2-2.4), renal insufficiency (OR 1.7; 1.3-2.2), and pulmonary history (OR 1.6; 95% CI 1.2-2.2). Age &lt;68 years proved to be a protective factor (OR 0.5; 95% CI 0.4-0.8). Associated mortality was higher in patients with intestinal ischemia versus patients without (50.6% vs. 5.1%, P &lt; 0.001). Each predictor was given a score between 1 and 4. Patients with a score of ≥10 proved to be at high risk. A prediction model with an excellent AUC = 0.873 (95% CI 0.855-0.892) could be formed.CONCLUSIONS: One of the main risk factors is open repair. Several other risk factors can contribute to developing colonic ischemia after AAA repair. The proposed prediction model can be used to identify patients at high risk for developing colonic ischemia. With the current trend in AAA repair leaning toward open repair for better long-term results, our prediction model allows a better informed decision can be made in AAA treatment strategy.</p
