Stent Stenosis

Background: Advances in stent technology have widened the field of indications for stent treatment of femoro-popliteal artery lesions, however the use of stents in bending arterial segments is restricted because some first- and second-generation nitinol stent designs did not respond well to the mechanical forces of femoro-popliteal segments in motion which pose a substantial risk of stent fracture inducing in-stent-stenosis. New generation nitinol stents are supposed to overcome these limitations but long-term results are rare. Patients and methods: In forty-five patients (mean age 68 y, range 50 - 85) with peripheral arterial disease (TASC II A-C, Rutherford category 2 - 5) forty-six lesions of the superficial femoral artery (37) or popliteal artery (9) were treated [25 high-grade stenoses, mean length 53 mm (range 30 - 145 mm); 21 chronic total occlusions, mean length 74 mm (range 30 - 180 mm)]. 74 % of lesions were located in the mobile bending arterial segments in the distal femoral or the popliteal segment. Clinical reevaluation performed at discharge, at 6, 12, 24, and 36 months included at least the measurement of ankle-brachial index (ABI) and duplex sonography. Results: Procedural success rate was 100 %. At 6, 12, 24, and 36 months, cumulative primary patency rate was 93.5 %, 84.8 %, 80.5 %, and 74.3 % (SE<10); freedom from target lesion revascularization rate was 95.7 %, 89.2 %, 84.9 %, and 79.3 % (SE<10); Rutherford category and ABI improved in all patients and clinical success was maintained in more than 85 % of patients. Conclusions: Sustained technical and clinical success and good clinical long-term results were achieved with Misago™ nitinol stent implantation in femoro-popliteal lesions with moderate risk for in-stent-stenosis, and in the distal femoral and popliteal mobile segment.

Medial Approach

The aim of this study was to evaluate the long-term outcomes of the surgical repair of popliteal artery aneurysms (PAAs), and to analyze the factors associated with graft patency. Between January 1980 and December 2013, 45 limbs were subjected to open surgical repair at Tokyo Medical and Dental Hospital. We retrospectively examined the patients' clinical characteristics, clinical symptoms, and aneurysm-related anatomy. Surgical procedures were performed through a posterior or medial approach using autologous vein or prosthetic graft. Surgical outcomes were evaluated by postoperative mortality, postoperative morbidity, graft patency, and limb salvage. During the study period, 45 limbs (35 patients; mean age, 60 years) underwent open surgical repair. A total of 25 limbs were treated through a posterior approach using 23 autologous vein grafts (AVGs) and 2 expanded polytetrafluoroethylene (ePTFE) grafts. The other 20 limbs were treated through a medial approach using 13 AVGs and 7 ePTFE grafts. During the mean follow-up period of 65 months, the primary patency rates at 1, 3, and 5 years were 88.0%, 75.7%, and 75.7%, respectively, and the limb salvage rates at 1, 3, and 5 years were 97.1%, 91.4%, and 91.4%, respectively. In the univariate analysis, the ligation and bypass grafting affected the primary patency rate significantly, and the ePTFE graft was associated with a poor primary patency in the multivariate analysis (hazard ratio, 17.8). The use of resection or endoaneurysmorrhaphy for PAAs and graft interposition with an AVG might be more effective for the open repair of PAAs.

Osteosynthesis Technique

Eighteen patients with distal humeral metaepiphyseal fractures were operated on during the period from 2010 to 2013. Mean age of patients made up 43.1±8.4 (22-72) years, term after injury - 4.6±1.9 (2-11) days. According to AO classification C1 fractures were diagnosed in 13, C2 - in 3, C3 - in 2 patients. In all patients distal humeral metaepiphyseal osteosynthesis with two plates placed at 90° to each other was performed. Surgical intervention was performed without olecranon osteotomy and triceps tendon was kept intact. In 12 (66.7%) cases longitudinal dissection of the triceps in its middle third was performed. Residual intraarticular displacement averaged 0.2±0.03 mm. Long term results were assessed in 10 patients at an average 12 months after operation. Mean score by subjective and objective scales made up 4.3±0.3 and 4.2±0.3 points, respectively. Main advantages of the applied osteosynthesis technique were preservation of forearm extensor muscles integrity; absence of additional fixatives in olecranon zone; absence of the necessity to perform additional intervention to remove fixatives from the olecranon.
