[Management of complications after revascularization due to peripheral arterial occlusive disease : Prophylaxis and consistent adequate therapy after timely diagnostics]. / Management von Komplikationen nach Revaskularisation wegen peripherer arterieller Verschlusskrankheit : Prophylaxe und konsequente adäquate Therapie nach zeitgerechter Diagnostik.

BACKGROUND: Complications are a threat to successful revascularization for treatment of perpheral arterial occlusive disease (PAOD) and must, therefore, be either primarily prevented or effectively treated after having occurred. OBJECTIVES: The aim of this article is to give a survey of possible complications after revascularization for treatment of PAOD and their management. MATERIAL AND METHODS: A systematic literature review was performed in PubMed and Medline. The analysis mainly considered recent publications with a higher level of evidence. RESULTS: Revascularization for treatment of PAOD can basically be performed by an open surgical approach, an endovascular approach or as a combination of both methods (hybrid operation). The spectrum of possible complications varies accordingly. A differentiation can be made between bleeding, ischemic and systemic complications as well as between vascular and non-vascular complications. Optimal management of complications begins with primary prophylaxis and further includes a timely diagnosis and treatment of established complications. The best prophylaxis consists of a high quality of indications and performance of revascularization. CONCLUSION: Optimal management of complications is essential and of utmost importance for successful revascularization to treat PAOD.

[Aneurysms of the abdominal aorta and iliac arteries: paradigm shift - operative therapy, if possible endovascular?]. / Aneurysmen der Bauchaorta und der Beckenarterien: Paradigmenwechsel - operative Therapie, wenn möglich endovaskulär?

BACKGROUND: Therapy of abdominal aortic aneurysms (AAA) is currently based on a high level of evidence. This is not true in the same manner for iliac artery aneurysms (IAA) which are frequently associated with AAAs and occur only rarely as isolated lesions. The therapeutic principles apply in the same way to both aneurysm locations. OBJECTIVES: New findings, improved perioperative care and the rapid development of minimally invasive techniques require a constant update which is the aim of this article concerning the therapy of AAAs and IAAs. MATERIAL AND METHODS: A systematic literature review was performed in PubMed and Medline and priority was given to recent publications with a high level of evidence. RESULTS: Endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) result in a similar long-term survival. The perioperative survival advantage with EVAR persists only during medium-term postoperative courses. The reintervention rate after EVAR is substantially higher compared to OAR. For older patients and those who are considered unfit for OAR the expected benefits from EVAR has not been proven to date. Aneurysmal ruptures after EVAR demonstrate that a life-long surveillance of these patients is necessary. CONCLUSION: Therapy of AAAs and IAAs is increasingly being performed by EVAR. Even the majority of complex aneurysms are amenable to minimally invasive treatment. Nevertheless, indications for OAR continue to exist. Screening for AAAs results in a decrease of aneurysmal ruptures for which EVAR is also gaining importance.
