PURPOSE To compare the effectiveness and patency of the TearLeader stent (PBN) for treatment of lacrimal system obstruction. METHODS A prospective study of 68 patients referred from the ophthalmology department with suspicion of lacrimal system obstruction. We placed 74 TearLeader PBN stents. Inclusion criteria were: complete obstruction of lacrimal duct with canalicula and lacrimal puncta pa...

OBJECTIVE Deep venous stenting has become the primary treatment option for chronic venous obstructive disease, both for iliac vein compression and post-thrombotic venous lesions. Until recently, only stents aimed at arterial pathology were used, because no dedicated venous stents were available. However, three such stents have now become available. These venous stents are characterized by incre...

Objective To examine patency of the cerebral anterior and posterior communicating arteries in patients with ischaemic stroke with or without diabetes mellitus. Methods This retrospective study included patients with acute ischaemic stroke treated between July 2011 and May 2016. Cerebral infarction was evaluated by magnetic resonance imaging. Anterior and posterior communicating-artery patency w...

BACKGROUND The long-term success of coronary bypass surgery is dependent on graft patency after surgery. This trial was designed to determine if aspirin improved saphenous vein graft or internal mammary artery (IMA) graft patency between 1 and 3 years after coronary artery bypass grafting (CABG). METHODS AND RESULTS After receiving aspirin 325 mg/d for 1 year after CABG and undergoing a 1-yea...

Diabetes is considered a risk factor for arteriovenous fistula failure and increased perioperative complications; but this view not proven patients undergoing brachiobasilic transposition (BBT-AVF). Fifty-one (68.9%) diabetic 23 (31.08%) non-diabetic single-stage BBT-AVF were compared in terms of complications, access maturation patency rates at The Aga Khan University Hospital from between Jan...

Percutaneous transluminal angioplasty (PTA) has gained wide acceptance as an effective technique for the dilatation of stenoses in the arterial tree. We evaluated the long-term results of vascular access in a group undergoing hemodialysis, in particular the effects of PTA. Twenty-four percutaneous procedures were performed on 18 patients. Detection was based on physical examination, flow rate m...

OBJECTIVE To compare radial artery (RA) patency with internal mammary artery (IMA) patency for coronary artery bypass surgery in our early experience. METHODS Symptomatic as well as asymptomatic patients with > or =1 RA coronary graft underwent postoperative angiography. Each anastomosis was considered separately. A string sign referred to a diffusely narrowed conduit, which did not fill the ...

OBJECTIVE To clarify the advantages and the influence to reproductive outcome after laparoscopic salpingotomy with and without suturing for tubal pregnancy. METHODS We retrospectively analyzed the clinical data of patients underwent laparoscopic salpingotomy from March 2012 to October 2014 who were willing to reserve their reproductive function and were able to be followed up. Based on the op...

PURPOSE To report a single-center study comparing drug-coated balloon (DCB) angioplasty vs directional atherectomy with antirestenotic therapy (DAART) for isolated lesions of the popliteal artery. METHODS Seventy-two patients were treated with either DCB angioplasty alone (n=31) or with DAART (n=41) for isolated popliteal artery stenotic disease between October 2009 and December 2015. The maj...
