[Comparison between hybrid surgical procedure--intraoperative angioplasty and cross-over bypass with aorto-bifemoral bypass in revascularization of iliac arteries].
OBJECTIVE
Authors analyze and compare hybrid vascular procedures (HOP) in revascularization of inflow arteries in the form of intraoperative stentangioplasty of iliac arteries combined with ilio/femoro-femoral cross-over bypass with conventional vascular procedures (KOP) in the form of aorto-bifemoral bypass.


METHODS
In all patients, admitted for bilateral revascularization of inflow arteries with hybrid or conventional procedure age, sex, comorbidity, stage according to the Fontain were reviewed prospectively. In all procedures following qualitative and quantitative data were collected: duration of the procedure, technical success (only in hybrid procedures), and peroperative mortality. In postoperative period following data were collected: wound healing problems, need for transfusion, need for observation in the ICU, duration of hospital stay, clinical success, patency and postoperative mortality 0-12 months after the operation. For statistical analysis of collected data statistical software SPSS 16 was used.


RESULTS
Within the year 2005-2007 (vascular centre Speyer - Mannheim) 20 hybrid procedures (HOP) in the form of intraoperative stentangioplasty of iliac arteries combined with ilio/femoro-femoral bypass were performed. Hybrid procedures were realized in 11 man (61.72 +/- 12.61) and 9 women (62.2 +/- 8.13). In similar indications was in the same period 14 conventional procedures (KOP) performed in the form of aorto-bifemoral bypass. Technical and clinical success were in HOP procedures achieved in 19 (95%) cases. Duration of operation was 97.36 +/- 19.04 minutes, duration of hospital stay was 8.94 +/- 4.01 days. Primary patency was in HOP procedures (0-12 months) observed in 19 (95%) cases. There was no perioperative and postoperative mortality observed during the follow up. A statistical analysis and comparison of hybrid and conventional procedures showed a significantly shorter duration of hybrid procedure (p < 0.001), significantly shorter hospital stay (p = 0.002), reduce wound healing problems (p = 0.022), need for transfusion therapy (p < 0.001) and need for observation in the ICU (p < 0.001) without a significant difference of clinical success and patency (0-12 m).


CONCLUSIONS
Hybrid procedures enormously expanded the possibilities of vascular surgery. In our opinion hybrid procedures in operative therapy of selected patients with symptomatic PAOD enable to reduce the extent of the operation, shorten the operating time, time of hospital stay and better the comfort for high risk patients. Using hybrid procedures especially in revascularization of inflow arteries enables to achieve good short-middle-term results with lower complication rates.
