Percutaneous endovascular treatment of peripheral arterial disease in Germany.

Purpose: The general distribution of balloon angioplasty, stenting and other endovascular interventions in treating peripheral arterial disease (PAD) is unclear.

Methods And Results: We used national statistics (DRG statistics) published by the Federal Statistical Office including data from almost all hospitals in Germany to calculate the rates and types of lower extremity endovascular procedures in 2012. In 2012 150,503 peripheral endovascular procedures were documented in Germany.

Percutaneous laser-assisted recanalization of long chronic iliac artery occlusions: primary and mid-term results.

We report the primary and mid-term outcome of patients with long chronic iliac artery occlusions after percutaneous excimer-laser-assisted interventional recanalization. Between 2000 and 2001, 43 patients with 46 chronic occlusions of either the common iliac artery (n=27), the external iliac artery ( n=13) or both (n=3) underwent laser-assisted percutaneous transluminal angioplasty and implantation of stents. The average length of the occlusion was 57.

Percutaneous interventional reconstruction of the iliac arteries: primary and long-term success rate in selected TASC C and D lesions.

We report the primary and long-term outcome of patients with selected TransAtlantic Inter-Society Consensus (TASC) C or D lesions of the iliac arteries after percutaneous interventional reconstruction. Between 1999 and 2001, 89 patients with peripheral arterial disease categorized as TASC C (n=37) and D (n=52) underwent percutaneous interventional reconstruction and stent implantation. Patients were followed for 1-62 months (mean 36 months).

Elevated fluid shear stress enhances postocclusive collateral artery growth and gene expression in the pig hind limb.

Objective: The role of fluid shear stress (FSS) in collateral vessel growth remains disputed and prospective in vivo experiments to test its morphogenic power are rare. Therefore, we studied the influence of FSS on arteriogenesis in a new model with extremely high levels of collateral flow and FSS in pig and rabbit hind limbs.

Methods And Results: A side-to-side anastomosis was created between the distal stump of one of the bilaterally occluded femoral arteries with the accompanying vein.
