Review article: Percutaneous transhepatic biliary drainage: Experience with 311 procedures

1988

Percutaneous biliary drainage was performed in 296 patients on 311 occasions using a fine-needle puncture technique. In 59%, the procedure served as postoperative decompression, and in 35% for palliation of obstruction, particularly in malignant disease. Postoperative drainage for the management of postoperative complication accounted for 2.5%. In more than 80% of the patients treated, the underlying disease was malignant obstructive jaundice. In 257 retrospectively evaluated patients the following complications were observed: cholangitis (6.6%), sepsis (3.1%), bile leakage (1.6%) with two deaths (0.7%), and subcapsular hematoma and hematoma in the hepatoduodenal ligament (1.2%). Catheter d…

Is preoperative radiographic localization of islet cell tumors in patients with insulinoma necessary?

1993

Preoperative localization tests [sonography, computed tomography, angiography, percutaneous transhepatic portal venous sampling for insulin radioimmunoassay (PTP)] have a sensitivity of 60% to 90% in cases of organic hyperinsulinism. In all publications, however, the sensitivity of intraoperative localization, 75% to 100%, is distinctly higher. With the exception of PTP, all tumors that can be identified by preoperative localization can also be detected using palpation or intraoperative sonography. Preoperative localization diagnosis is therefore not absolutely necessary prior to primary operation in the case of organic hyperinsulinism. It is requested by many surgeons because: (1) only a f…

Percutaneous Femoropopliteal Bypass: 2-Year Results of the DETOUR System

2021

Purpose: This study investigated the 2-year safety and effectiveness of the PQ Bypass DETOUR system as a percutaneous femoropopliteal bypass. Materials and Methods: Seventy-eight patients with 82 long-segment femoropopliteal lesions were enrolled in this prospective, single-arm, multicenter study. The DETOUR system deployed Torus stent grafts directed through a transvenous route. Eligible patients included those with lesions of >10 cm and average of 371±55 mm. Key safety endpoints included major adverse events (MAEs) and symptomatic deep venous thrombosis in the target limb. Effectiveness endpoints included primary patency defined as freedom from ≥50% stenosis, occlusion, or clinically-d…

Ovarian cysts in the fetus and neonate--changes in sonographic pattern in the follow-up and their management.

1992

In a multicenter trial we retrospectively evaluated the clinical and sonographic data of 49 neonatal ovarian cysts, 44 of which were detected prenatally and 5 on the first day after delivery. Of the 44 prenatally detected cysts 39 were purely cystic, 5 echogenic or had a mixed pattern. In 20 patients the cystic appearance changed during delivery from purely cystic to a mixed pattern being independent on the size of the cyst. 26 of the 44 cysts were treated surgically. Salpingotorsion was found in 8 and was independent on the size of the cyst. In 15 a salpingo-oophorectomy or oophorectomy was performed, in 11 the ovary was saved. 23 patients were followed sonographically: 15 cysts showed com…

Oral health related quality of life and determinant factors in patients with head and neck cancer.

2018

Background The present study aimed to measure the impact of oral health on the quality of life of patients with head and neck cancer. Material and Methods A cross-sectional study was conducted with 130 patients diagnosed with head and neck cancer at two medical centers. Participants answered a sociodemographic questionnaire and the Oral Health Impact Profile - 14 (OHIP-14). Clinical aspects, cancer staging, and treatment approach were also investigated. Mann-Whitney and Kruskal-Wallis non-parametric tests were used for statistical analysis, followed by Poisson regression analysis (with robust error variance), to associate the OHIP-14 scores with independent variables. Results The OHIP-14 pr…

Endovascular management of a giant symptomatic gluteal artery aneurysm with selective arterial embolization

2017

A 78-year-old female presented to our department with pain and swelling in the left gluteal region. Physical examination revealed a large tender swelling in the left gluteal area simulating an abscess. However, pulsation was observed over the swelling that raised the suspicion of a vascular lesion. Therefore, contrast-enhanced computed tomography (CT) was done before trying any intervention. The scan demonstrated a large aneurysm originating from the left superior gluteal artery measuring 65 mm × 38 mm with a small intra-pelvic component and large extra-pelvic component in the gluteal area ( Figure 1 ).

AORTIC STIFFNESS IS INCREASED IN NORMOTENSIVE PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS

2018

INTRODUCTION: Patients with systemic lupus erythematosus (SLE) have a 4- to 10-fold increased risk of developing cardiovascular (CV) events compared with the general population. The enhanced CV risk conferred by SLE may in part be mediated through preclinical CV damage. Large artery stiffness is usually assessed by measuring aortic pulse wave velocity (aPWV), a marker of early vascular aging (EVA) and an independent predictor of adverse CV prognosis. Several studies examined aortic stiffness in SLE with inconsistent results. AIM: To evaluate aPWV and the prevalence of EVA in a group of normotensive patients with SLE and to compare these values with those obtained in age- and gender- matched…

Feasibility of future epidemiological studies on possible health effects of mobile phone base stations.

2006

The increasing deployment of mobile communication base stations led to an increasing demand for epidemiological studies on possible health effects of radio frequency emissions. The methodological challenges of such studies have been critically evaluated by a panel of scientists in the fields of radiofrequency engineering/dosimetry and epidemiology. Strengths and weaknesses of previous studies have been identified. Dosimetric concepts and crucial aspects in exposure assessment were evaluated in terms of epidemiological studies on different types of outcomes. We conclude that in principle base station epidemiological studies are feasible. However, the exposure contributions from all relevant …
