Tapered Sutures for Vascular Surgery

Adjustable sutures in squint surgery.

Human hair sutures in ophthalmic surgery.

Hairs varying from 6 to I2 in. in length were obtained mostly from women and in some cases from Sikh male members of the department. The hairs selected, after brittle, coarse, or extremely thin hairs had been discarded, were cleaned with 2 per cent. cetavlon, washed in water, wrapped around rubber tubing about 3 in. long to minimize curling, put into a wide-mouthed bottle, and autoclaved for 20...

Choosing Sutures in Small Animal Surgery

Sutures role in wound repair process is to provide hemostasis and support for healing tissue [1-6]. Different tissues have differing requirements for suture support because they heal at different rates. Some tissues need support for only a few days (e.g. muscle, subcutaneous tissue, skin), whereas others require weeks (fascia) or even months (tendon) to heal. Patient variations further affect s...

Development of Absorbable, Antibiotic-Eluting Sutures for Ophthalmic Surgery

PURPOSE To develop and evaluate an antibiotic-eluting suture for ophthalmic surgery. METHODS Wet electrospinning was used to manufacture sutures composed of poly(L-lactide), polyethylene glycol (PEG), and levofloxacin. Size, morphology, and mechanical strength were evaluated via scanning electron microscopy and tensile strength, respectively. In vitro drug release was quantified using high pe...

Applications of Cell Therapy in Vascular Surgery

Trying to use embryonic stem cells about 20 years ago, working with animals,  especially rats began. During these years , many experiments in mouse embryonic stem cells to transform into a variety of cells and transplanting them were led to remarkable success . In the next issue of human stem cells were considered successful until finally in 1998 the first report was published in the proliferat...
