What are the different types of VSD?
There are four basic types of VSD:
- perimembranous VSD - an opening in a particular area of the upper section of the ventricular septum (an area called the membranous septum), near the valves. This type of VSD is the most commonly operated upon since most perimembranous VSDs do not spontaneously close.
- muscular VSD - an opening in the muscular portion of the lower section of the ventricular septum. This is the most common type of VSD. A large number of these muscular VSDs close spontaneously and do not require surgery.
- atrioventricular canal type VSD - a VSD associated with atrioventricular canal defect. The VSD is located underneath the tricuspid and mitral valves.
- conal septal VSD - the rarest of VSDs which occur in the ventricular septum just below the pulmonary valve.

accreta - does not penetrate the entire thickness of the muscle. T
increta- placenta further extends into the myometrium, penetrating the muscle.
percreta-penetrates the entire myometrium to the uterine serosa (invades through entire uterine wall). This variant can lead to the placenta attaching to other organs such as the rectum or bladder.

Type I injury (image)
type I urethral injury with minimal stretching and slight luminal irregularity of the posterior urethra. No extravasation of contrast material is present. type II urethral disruption. Extravasation of contrast material from the posterior urethra is seen superior to an intact urogenital diaphragm type III urethral tear at the urogenital diaphragm
type IV urethral disruption at the bladder neck
type V urethral injury with extravasation of contrast material from the distal bulbous urethra.
