C-Section Nightmare, Wound V.A.C. and malpractice question?

This is going to be kind of long. Sorry.

I had a c-section on 4/20 (footling breech baby). They removed my staples on 4/23 and steri-stripped it and sent me home. I had a big bruised area (hematoma) which they were aware of when they sent me home. The following Sunday, I noticed my wound was opening back up. I went in to the emergency room, and they discovered that the hematoma appeared to be spreading. In addition, they drew my hemocrit and found my hemoglobin to be a 7 (normal is 12, I believe). They admitted me to the hospital and put me on blood transfusions, 3 units.

On 4/27 they performed a wound debridement surgery on my abdomen to fix the bleeding area that was causing the hematoma. I was stapled, and outfitted with a Jackson-Pratt drain. I went home a few days later with the drain and staples still in.

Ten days post-discharge, I went in for a follow-up. The doctor discovered a small area of my wound had popped free of the staples and was open. He pulled my drain and staples and informed me to keep it dry and clean.

Today I had my next follow-up visit. I saw a different doctor, and she discovered the wound had opened up quite a bit more. She packed it with iodiform packing and wants to put in a wound v.a.c. This has been one long nightmare, and it's very difficult for me to care for two children with all of this going on (I have the newborn and a two year old).

So my questions are as follows:

1. What kind of experience is having a wound v.a.c.? How long is one normally in?

2. Could any of these complications have been caused by my a doctor, and is there a possibility for a lawsuit?
