[Options and Management of Vascular Reconstruction in the Context of Abdominal Surgery and its Perioperative Care - Selection of Typical Clinical Situations and Cases]. / Möglichkeiten und Management gefäßrekonstruktiver Eingriffe im Rahmen viszeralchirurgischer Operationen und ihrer perioperativen Betreuung ­ eine selektive Auswahl repräsentativer Fallkonstellationen.

INTRODUCTION: Interdisciplinary cooperation between surgeons can help to optimise outcome in the management of complex surgical diseases. The indication for surgical intervention has gradually expanded in advanced multivisceral tumour growth, with iatrogenic vascular injuries in the field of abdominal and oncological surgery and mesenteric ischemia. Appropriate expertise in vascular surgery is then essential, although this is not always available or in all hospitals. AIM: Narrative review based on current scientific references in the relevant literature and our own clinical and surgical experiences in decision making, the approach in clinical management and various options of vascular reconstruction in abdominal surgery. RESULTS: Prognosis is still limited in pancreatic cancer. R0 resection is the only curative therapeutic option - thus, the surgeon has to provide specific intraoperative expertise. Arterial reconstruction is still controversial, due to increased postoperative morbidity and limited evidence. But in specific cases, venous reconstruction has been established in clinical practice. In addition, in retroperitoneal sarcoma with advanced/extended tumour growth, reconstruction of the infiltrated inferior V. cava or common iliac artery by means of patch plasty or autologous bypass/segmental vascular prosthesis can become necessary as part of multivisceral resections. During inflammatory processes or with tumour adhesions/infiltrations to surrounding anatomical structures, intraoperative vascular injuries or postoperative vascular alterations can occur, further complicated by anatomical variants. The extremely strict demands on the abdominal surgeons, in particular in mesenteric ischemia, are influenced by i) a competent assessment of the mesenteric vessels based on ii) adequate imaging as well as iii) appropriate time management. Prompt recanalisation can play a decisive role for the prognosis. CONCLUSION: Vascular reconstructions in abdominal surgery, in particular, in oncological surgery, require great expertise of the surgeon. In this context, competent preoperative diagnostic testing, extensive specific experience in vascular surgery/interventions, appropriate interdisciplinary case management, adequate surgical tactic and technique are all important.
