Craniofacial venous malformations treated by percutaneous sclerotherapy using polidocanol: a single-center experience.

2018

Background Percutaneous therapy with various sclerosants is an established treatment of venous malformations in general. We investigated the safety and effectiveness of polidocanol in the craniofacial region. Purpose To present and evaluate our subjective and objective mid- and long-term results of patients with craniofacial venous malformations (CFVM) after percutaneous sclerotherapy using polidocanol. Material and Methods Twenty patients with CFVM treated by percutaneous sclerotherapy were followed up and asked to fill in a questionnaire comparing levels of the following CFVM-related symptoms before and after treatment: pain; functional impairment; cosmetic deformities; and impairment in …

Das Verhalten der Kollateralen bei der perkutanen transluminalen Angioplastie

1990

The fate of 106 collaterals was investigated following percutaneous transluminal dilatation of 113 stenoses and occlusions. Following dilatation, 78% of collaterals were unchanged and 22% could no longer be demonstrated. The success of the dilatation had no bearing on the fate of the collaterals. Collaterals beginning or ending in a dilated portion of vessel disappeared more frequently (30%) than the others (11%). Following five dilatations, some vessels were demonstrated in the area of stenosis, which had not been demonstrated previously. Evidently local events, such as displacement of arteriosclerotic plaques may lead to occlusion or reopening of vessels. Remaining collaterals may be of g…

Percutaneous puncture of an aorto‐bifemoral bypass graft and successful closure with MANTA ® device in transfemoral TAVR

2021

Transfemoral aortic valve replacement (TAVR) has become a standard therapeutic option for patients with symptomatic severe aortic stenosis. Special anatomies can pose distinct challenges for vascular access and later closure of the access site, for example, in preoperated patients. Here, we elucidate a case of transfemoral TAVR with vascular access by direct puncture of an aorto-bifemoral bypass graft and illustrate the feasibility of vascular closure by an anchored collagen-plug vascular closure device (Teleflex MANTA® ).

Evaluating the quality of implantation of percutaneous ventricular restoration device (Parachute®) by cardiac computed tomography

2016

Background The Parachute is a novel percutaneously implanted ventricular partitioning device (VPD) that has emerged as a safe and feasible treatment option for patients with heart failure following anterior wall myocardial infarction. VPD efficacy is likely dependent on optimal device placement, but to date there are no published data examining the effect of device positioning on patient outcomes. Methods and results We retrospectively identified 32 patients successfully implanted with the Parachute device, all of whom underwent cardiac computed tomography (CCT) at baseline and after 6 months of follow-up. Patients were divided into two groups based on self-reported improvement in New York …

Die Diagnostik des hilären Cholangiokarzinoms: Wertigkeit von präoperativer ERC, MRC und PTC im Vergleich zur Histopathologie

2005

PURPOSE To compare the results of the preoperative workup consisting of endoscopic retrograde cholangiography (ERC), magnetic resonance cholangiography (MRC), and percutaneous resonance cholangiography (PTC) with the tumor extent of the surgical specimen in patients with hilar cholangiocarcinoma (hilCC). MATERIALS AND METHODS Between 9/1997 and 12/2002, 59 patients with hilCC tumor underwent surgical resection. Preoperative ERC, MRC, and PTC were analyzed, blinded for the identity of the patient, and compared with the surgical specimen. For this retrospective analysis, 55 of the initial 59 ERCs, 39 of the initial 40 MRCs and 32 of the initial 38 PTCs were available. Most of the ERCs and MRC…

Verschlußikterus: histologische Diagnostik durch perkutane endoluminale Gallengangsbiopsie

1991

32 forceps biopsies were performed in 30 patients with obstructive jaundice during percutaneous transhepatic biliary drainage procedures. In one patient an adequate specimen could not be obtained. In 25 of the remaining 31 cases diagnosis was confirmed histologically (malignant tumours: n = 22, benign stricture: n = 3). In 6 patients false-negative results were obtained. Transluminal biopsy is an easily performed adjunct to percutaneous transhepatic diagnostic interventions with minimal additional discomfort for the patient. In many cases percutaneous needle biopsy can be avoided. Forceps biopsy enables nonoperative histological diagnosis of small carcinomas of the bile ducts.

Die direkte perkutane radiologische Jejunostomie (PRJ) und Duodenostomie: eine retrospektive Auswertung

2005

Purpose: To present our experience with direct percutaneous radiologic duodenostomy and jejunostomy (PRJ) for alimentation. Materials and Methods: A retrospective study identified 24 patients who had undergone percutaneous jejunostomy or duodenostomy guided by CT and fluoroscopy over a period of 9 years. Whenever possible, the jejunum was inflated with a 5 French diagnostic catheter and jejunopexy was performed using Cope anchors (T-fasteners). A 12 to 14 French locking pigtail drain was inserted for alimentation. In 8 patients, percutaneous direct jejunostomy was performed using only fluoroscopy. In 9 patients, both CT and fluoroscopy were used to guide the jejunostomy. In all 7 patients w…

Angiographien im Kleinkindes- und Kindesalter

1993

Between 1973 and 1991 we performed 160 percutaneous angiograms (130 arteriograms, 30 phlebograms) in children and infants; 12 patients were less than one year and 52 less than ten years old. 44 of the examinations were done by a DSA technique. The examinations were carried out under general anaesthesia except in 8 cases. In 50.7% an arteriogram was carried out for the investigation of a suspected or known tumour, in 9.3% an arteriogram was required following trauma. The most common phlebographic examination was for the demonstration of the spermatic vein; in 27 patients this was done for cryptorchidism or a varicocele. The only complication following a diagnostic angiogram was perforation o…
