Chirurgische und interventionelle Behandlung der chronisch-kritischen Beinischämie

Die chronisch-kritische Beinischämie (CLI) ist die schwerste Form der peripher-arteriellen Verschlusskrankheit und geht mit einem erhöhten Risiko für letale kardiovaskuläre Ereignisse einher. Die meisten Patienten überleben aber die ersten Jahre nach Diagnosestellung und sind für den Erhalt ihrer Selbständigkeit auf eine nachhaltige Verbesserung der Beindurchblutung angewiesen. Dieser CME-Artikel fasst die chirurgischen und endovaskulären Optionen zur Revaskularisierung zusammen und geht auf deren Nachhaltigkeit bei CLI ein. Grenzen der verfügbaren Evidenz werden aufgezeigt. Sie beruhen vor allem auf dem Fehlen einer einheitlichen Definition des Behandlungserfolges. Ein klinisch orientierter Lösungsvorschlag wird diskutiert, der helfen könnte, die verschiedenen Behandlungsindikationen zu schärfen. Da sich aber nur die wenigsten Patienten gleich gut für verschiedene Verfahren eignen, werden CLI-Patienten auch in Zukunft am besten in einem interdisziplinär arbeitenden Team betreut sein.

Massive pulmonary embolism: surgical embolectomy versus thrombolytic therapy--should surgical indications be revisited?

The treatment of massive pulmonary embolism (PE) is a matter of debate. We present our institutional experience of patients suffering from massive PE with the aim of comparing the early results, the outcome and quality of life (QoL) between patients primarily assigned to either pulmonary surgical embolectomy (SE) or thrombolytic therapy (TL). A subgroup of patients (TS) with failed responses to TL requiring SE was separately analysed.

The unspoken disease: symptom experience in women with vulval neoplasia and surgical treatment: a qualitative study

Women with vulval neoplasia often experience severe post-surgical complications. This study focuses on symptom experience of women during the first 6 months following surgical treatment for vulval neoplasia considering their socio-cultural context. In this qualitative study using a critical hermeneutic approach, narrative interviews were conducted. A purposeful sample of 20 patients was recruited from one Swiss and two German university hospitals. Content analysis was employed to analyse the transcribed interviews considering women's experiences and social perceptions. Narratives showed eight interrelated themes: delayed diagnosis, disclosed disease, disturbed self-image, changed vulva care, experienced wound-related symptoms, evoked emotions, affected interpersonal interactions and feared illness progression. The women experienced a general lack of information pertaining to above themes and all described strategies used to handle their situation, which affected their distress. The communication, assessment and treatment of symptoms were hampered by the society's and the health system's tendency to overlook these symptoms and leave them in the realm of the unspeakable. Health professionals need new strategies to support these women to recognise, assess and evaluate the seriousness of symptoms, and to communicate their symptom experience so that timely medical treatment is sought. This support may minimise potentially preventable complications and symptom-related distress.

Computer-assisted femoral head-neck osteochondroplasty using a surgical milling device an in vitro accuracy study

Surgical navigation might increase the safety of osteochondroplasty procedures in patients with femoroacetabular impingement. Feasibility and accuracy of navigation of a surgical reaming device were assessed. Three-dimensional models of 18 identical sawbone femora and 5 cadaver hips were created. Custom software was used to plan and perform repeated computer-assisted osteochondroplasty procedures using a navigated burr. Postoperative 3-dimensional models were created and compared with the preoperative models. A Bland-Altmann analysis assessing α angle and offset ratio accuracy showed even distribution along the zero line with narrow confidence intervals. No differences in α angle and offset ratio accuracy (P = 0.486 and P = 0.2) were detected between both observers. Planning and conduction of navigated osteochondroplasty using a surgical reaming device is feasible and accurate.

Comparison of titanium-nitride-oxide-coated stents with zotarolimus-eluting stents for coronary revascularization a randomized controlled trial

Objectives This study sought to compare the efficacy of passive stent coating with titanium-nitride-oxide (TiNO) with drug-eluting stents releasing zotarolimus (ZES) (Endeavor, Medtronic, Minneapolis, Minnesota). Background Stent coating with TiNO has been shown to reduce restenosis compared with bare-metal stents in experimental and clinical studies. Methods In an assessor-blind noninferiority study, 302 patients undergoing percutaneous coronary intervention were randomized to treatment with TiNO or ZES. The primary endpoint was in-stent late loss at 6 to 8 months, and analysis was by intention to treat. Results Both groups were well balanced with respect to baseline clinical and angiographic characteristics. The TiNO group failed to reach the pre-specified noninferiority margin for the primary endpoint (in-stent late loss: 0.64 ± 0.61 mm vs. 0.47 ± 0.48 mm, difference: 0.16, upper 1-sided 95% confidence interval [CI]: 0.26; pnoninferiority = 0.54), and subsequent superiority testing was in favor of ZES (psuperiority = 0.02). In-segment binary restenosis was lower with ZES (11.1%) than with TiNO (20.5%; psuperiority = 0.04). A stratified analysis of the primary endpoint found particularly pronounced differences between stents among diabetic versus nondiabetic patients (0.90 ± 0.69 mm vs. 0.39 ± 0.38 mm; pinteraction = 0.04). Clinical outcomes showed a similar rate of death (0.7% vs. 0.7%; p = 1.00), myocardial infarction (5.3% vs. 6.7%; p = 0.60), and major adverse cardiac events (21.1% vs. 18.0%, hazard ratio: 1.19, 95% CI: 0.71 to 2.00; p = 0.50) at 1 year. There were no differences in rates of definite or probable stent thrombosis (0.7% vs. 0%; p = 0.51) at 1 year. Conclusions Compared with TiNO, ZES was superior with regard to late loss and binary restenosis. The concept of passive stent coating with TiNO remains inferior to drug-eluting stent technology in reducing restenosis.
