Operative report
Preoperative diagnosis: Lumbar spinal stenosis
Postoperative diagnosis: L4-L5 spinal stenosis (Post-operative diagnosis of lumbar (L4-L5) stenosis.)
Procedure:
L4-5 laminectomy, removal of synovial cyst, bilateral medial facetectomy and posterolateral fusion L4-L5 with vertebral autograft, bone morphogenic protein, chip allograft, all with intraoperative somatosensory evoked potentials, electromyographies and loupe magnification. (The following procedures were performed: L4-5 laminectomy, removal of synovial cyst, bilateral medial facetectomy and posterolateral fusion L4-L5 with vertebral autograft, bone morphogenic protein, chip allograft, all with intraoperative somatosensory evoked potentials, electromyographies and loupe magnification. The Laminectomy is more complex and carries a higher base value.)
Anesthesia: General endotracheal (Type of anesthesia is general.) anesthesia.
Description of Procedure:
The patient was taken to the operating room and underwent intravenous anesthetic and orotracheal intubation. Her head was placed in the three-pin Mayfield headrest. She was turned into the prone position on a four-poster frame. All pressure points were carefully padded. The fluoroscope was brought in and sterilely draped to help localize the incision.
A midline incision was made between L4 and L5 through skin and subcutaneous tissue and the paraspinal muscles were dissected free of the spinous process, lamina, facets and L4, L5 transverse processes. Self-retainers were placed more deeply. We proceeded to use the double-action rongeur to remove the L4-L5 spinous process lamina. 3 and 4 millimeter Kerrison punches were used to complete the laminectomy including removing the hypertrophied ligamentum flavum. We made sure that we decompressed from the top of the L4 pedicle to the bottom of the L5 pedicle, which was confirmed with intraoperative fluoroscopy. The medial facets were drilled and then we undercut over the nerve roots with a 3 millimeter Kerrison punch. Hemostasis was achieved with powdered gelfoam. We irrigated the wound. We decorticated the L4 and L5 transverse processes. We placed our vertebral autograft, bone morphogenic protein and chip allograft in the posterolateral gutters. Hemovac drain was placed. We closed the muscle with 0 Vicryl. Fascia was closed with 0 Vicryl. Subcutaneous tissue was closed with 2-0 Vicryl and the skin was closed with staples.

NAME OF PROCEDURE: Sternal wound exploration and wound vac placement.(Procedure performed.)
ANESTHESIA: Monitored Anesthesia Care(Use modifier QS to indicate MAC is used.)
BRIEF HISTORY: He is a 52-year-old patient who is two weeks out from re-do sternotomy and aortic valve replacement for critical aortic stenosis in the setting of heart failure. He had a postoperative coagulopathy and required sternal re-exploration with open packing.(The wound is a post-operative complication.) He was closed the next day. He had serous discharge prior to going home but this was culture negative and the wound looked very good. He continued to have serous discharge in the clinic and it was felt he had a retained hematoma. He was scheduled for evaluation of the hematoma and wound vac placement. This was done without incident. He did not have any evidence of infection. There was no evidence of any sternal instability.
DESCRIPTION OF OPERATIVE PROCEDURE: Following delivery of the patient to the operating room, the patient was placed on the operating table, prepared and draped in the usual sterile manner. His upper abdominal wound was explored. There was hematoma at the base of the wound which was very carefully evacuated(Confirms a postoperative hematoma.) and the wound was irrigated with antibacterial solution. A wound vac was then placed with the assistance of the wound care nurse.(Wound vac placed by a wound care nurse.) The patient was returned to the PCU in stable condition.

Operative Report
Preoperative diagnosis: Stricture of the left ureter, postoperative
Postoperative diagnosis: SAME(Postoperative diagnosis is the same as preoperative which is stricture of the left ureter, postoperative.)
Procedure:
- Cystoscopy of ileal conduit.
- Exchange of left nephroureteral catheter.
Anesthesia: Monitored anesthesia care.(Modifier QS is used to indicate MAC.)
Description of Procedure: The patient is identified in the holding area, marked, taken to the operating room. Subsequently, she was given monitored anesthesia care. She was prepped and draped in the usual sterile fashion in the supine position. Next, using a flexible cystoscope, the ileal conduit was entered. Cystoscopy was performed, which showed the ureteroileal anastomosis on the left with a stent protruding from it. There were no calcifications seen on the stent. Thus, the cystoscope was removed from the ileal conduit and then a super stiff wire was advanced through the nephroureteral catheter, up into the kidney. Once it was up there, then the catheter was taken off of the wire and then a new 8-French x 28-centimeter, nephroureteral ureteral catheter was advanced fluoroscopically into the level of the kidney. Once this was done and its position was confirmed fluoroscopically, the wire was pulled. A good curl was there fluoroscopically in the kidney, as the wire was pulled. A good curl was seen in the bladder and then the distal end was protruding out from the ileal conduit. This was placed in the ostomy bag and the patient was taken in stable condition to the recovery room.

PREOPERATIVE DIAGNOSIS: Multivessel coronary artery disease.
POSTOPERATIVE DIAGNOSIS: Coronary artery disease, native artery
NAME OF PROCEDURE: Coronary artery bypass graft x 3, left internal mammary artery to the LAD, saphenous vein graft to the obtuse marginal, saphenous vein graft to the diagonal.
ANESTHESIA: General
BRIEF HISTORY: This 77-year-old patient who was found to have a huge aneurysm. Preoperative cardiac clearance revealed a markedly positive stress test and cardiac catheterization showed critical left-sided disease. Coronary revascularization was recommended. The patient has multiple medical illnesses including chronic obstructive pulmonary disease with emphysema and chronic renal insufficiency. I discussed with the patient and the family, the risks of operation including the risk of bleeding, infection, stroke, blood transfusion, renal failure, and death. At operation, we harvested a vein from the left leg using an endoscopic technique that turned out to be a very good conduit. Her obtuse marginal vessel was a 1.5-mm diffusely diseased vessel that was bypassed distally as it ran in the left ventricular muscle. The diagonal was a surprisingly good vessel at 1.5-mm in size. The LAD was bypassed in the mid aspect of the LAD and there was distal disease though a 1.5-mm probe passed quite easily. Good flow was measured in the graft. The patient came off bypass very nicely. Note should be made that her ascending aorta was calcified and we used a single clamp technique.
DESCRIPTION OF OPERATIVE PROCEDURE: Following delivery of the patient to the operating room, the patient was placed under general anesthetic, was prepped and draped in the usual sterile manner. Arterial line through the skin, right pulmonary artery catheter and a left subclavian central lines were placed by the Anesthesia Department. A median sternotomy was made and the left internal mammary artery was harvested from the left chest wall, the saphenous vein was harvested from the left leg. The patient was heparinized and cannulated and placed on cardiopulmonary bypass |8| with an aortic cannula on the undersurface of the aortic arch and a venous cannula through the right atrial sidewall. Note should be made that the upper aorta was very heavily calcified, but the area that we cannulated was felt to be disease free. The aorta was cross clamped and the heart was stopped with antegrade and retrograde cardioplegic solution. The heart was retracted out of the pericardial sac and then displaced into the right chest which afforded good access to the lone marginal vessel which was bypassed with a reversed saphenous vein graft using a running 7-0 Prolene suture. Cold cardioplegic solution was then instilled down this graft. Note should be made that during the mammary artery harvest, the left lung was completely adherent to the left chest wall, most likely from old episodes of pneumonia. Next, a second saphenous vein segment was placed to the diagonal vessel and then the left internal mammary artery was placed to the mid LAD. As noted, there was diffuse calcification distally in this artery just beyond the anastomosis, but the 1.5 mm probe passed very nicely and we felt that it was not necessary to double jump this LAD. With the cross clamp in place, two proximal aortotomies were made and the two proximal anastomoses were formed using 6-0 Prolene in a running fashion. Just prior to completion of the second anastomosis, appropriate de-airing maneuvers were performed and then the suture lines were tied as the cross clamp was removed. The patient was allowed to rewarm completely and was weaned from bypass. The cannulas were removed and the cannulation sites were secured with pursestring sutures. Once hemostasis was secured, chest tubes were placed and the wound was closed. Final needle, instrument, and sponge counts were reported as correct. The patient tolerated the procedure well and returned to the recovery room in stable condition.
