background: venoplasty and stenting is a minimally invasive therapy that can be used for patients with deep venous insufficiency in the lower extremities. this study aimed at investigating the effect of venoplasty and venous stenting in patients with chronic venous insufficiency in the lower limbs. methods : this prospective case-series study recruited patients with chronic deep venous insuffic...

OBJECTIVES To evaluate longer-term safety and efficacy of a single self-expanding stent up to 20 cm in length in patients with atherosclerotic disease of the superficial femoral (SFA) and proximal popliteal arteries. BACKGROUND Angioplasty and stenting are options for revascularization of symptomatic peripheral artery disease. While angioplasty alone is effective in short lesions, outcomes in...

PURPOSE To evaluate the patency and the freedom of target lesion revascularization of the 4-French Pulsar-18 self-expandable (SE) nitinol stent for the treatment of long femoropopliteal occlusive disease in a two-center, prospective, all-comers registry with a follow-up period of 12 months. METHODS This registry enrolled 36 patients with symptomatic femoropopliteal long lesions for recanaliza...

BACKGROUND There is no consensus about the value of objective measurements of nasal patency. OBJECTIVE To assess the correlation between the subjective sense of nasal patency and the outcomes found with rhinomanometry and acoustic rhinometry. TYPE OF REVIEW Structured literature search. SEARCH STRATEGY AND EVALUATION METHOD: Review of English-language articles in which correlations were sou...

BACKGROUND Retention is the most common complication of capsule endoscopy (CE), and is reported to occur in 0-13% of cases. To avoid retention, a PillCam patency capsule (PC) is used in patients with suspected intestinal stenosis. However, a relatively low positive predictive value of the PC examination has been reported previously. The aims of this study were to clarify the accuracy of PC exam...

BACKGROUND Little information exists regarding mid-term and long-term patency of radial artery grafts. METHODS AND RESULTS We performed restudy coronary angiography at 5.2+/-0.4 years after surgery on 50 asymptomatic patients who had undergone coronary artery bypass graft surgery, using at least 1 radial artery graft, to determine both graft patency and presence of narrowing. We examined preo...

Recent progress in chemotherapy has prolonged the survival of patients with malignant biliary strictures, leading to increased rates of stent occlusion. Even we employed metallic stents which contributed to higher rates and longer durations of patency, and occlusion of covered metallic stents now occurs in about half of all patients during their survival. We investigated the complication and pa...

BACKGROUND The eSVS® external venous nitinol mesh (Kips Bay Medical, Minneapolis, USA) was designed to improve long-term patency of coronary saphenous vein grafts (SVG) by preventing pressure-induced wall stress and reactive neo-intimal hyperplasia. We present one-year-patency rates of meshed SVGs assessed by coronary computed tomographic angiography (cCTA). PATIENTS AND METHODS Data from con...

Vasectomy is a simple and reliable method of male contraception. A growing number of men after vasectomy request vasectomy reversal due to various reasons. The pregnancy rate is lower than the patency rate after vasovasostomy and the pregnancy rate is time dependent. In this study, we evaluated the influence of reproductive tract obstruction on expression of epididymal proteins and their restor...

BACKGROUND We previously reported 48-month patency rates of composite sequential bypass (CSB) approaching 60%. Yet, extended patency and limb salvage rates are unknown. HYPOTHESIS Long-term patency and limb salvage rates of CSB are affected by sex, bypass configuration, and warfarin therapy. DESIGN Medical records of all patients who underwent CSB during a 10-year period were retrospectivel...
