Sutures

Question 1

Answer 1

Donati / Interrupted vertical mattress suture (vertical U)

• appositional to everting
• stronger in tissues under tension than interrupted horizontal mattress sutures
• a single layer can be used for skin and subcutis closure to eliminate dead space
• skin, subcutis, fascia

Question 2

Answer 2

Allgöwer stitch (Modified Donati)

• appositional
• it enters the skin on one side of the wound
• holds broad amount of tissue not disrupting as much of the vertical blood flow as a truly horizontal/vertical mattress
• skin, subcutis

Question 3

Answer 3

Interrupted cruciate (cross mattress)

• appositional
• 2 simple interrupted sutures parallel to each other are tied
• stronger than simple interrupted, prevents eversion
• skin, subcutis

Question 4

Answer 4

Continuous lock or Ford interlocking

• similar to simple cont. except that it provides greater security if broken
• skin, horse uterus incision margin

Question 5

Answer 5

Continuous intradermal/intracutan

• appositional
• minimal impact on the local blood supply of the skin

Question 6

Answer 6

Continuous Lembert s.

• inverting
• continuous, variation of vertical mattress suture, penetrates the submucosa but not the lumen (sero- musculo-submucosal stitch)
• closure of hollow viscera

Question 7

Answer 7

Continuous Cushing

• inverting
• penetrates the submucosa, but not the lumen of the bowel, provides less inversion than Lembert

Question 8

Answer 8

Continuous Connell

• penetrates the mucosa into the lumen)
• more effect on the local blood supply than a simple continous suture
• closure of hollow viscera

Question 9

Answer 9

Parker-kerr

• Cushing over a clamp, which will be removed afterwards and then is oversewn with a cont. layer of Lembert
• closure of hollow visceral stumps
