Objectives:
To review simultaneous intra-operative sclerotherapy (IOS) with immediate surgical resection for the treatment of cervicofacial venous malformations (VMs) at a single institution. While pre-operative sclerotherapy (POS) has been reported in the literature, simultaneous intra-operative sclerotherapy and surgery in the operating room has not.
Methods:
The database from the Hemangioma and Vascular Birthmarks Clinic was reviewed. All patients in both groups had biopsy-proven VMs.
Results:
IOS was used in 11 surgical patients with average age 17 years. Sclerotherapy was performed with sodium tetradecyl sulfate 3%, absolute alcohol or bleomycin. Immediately after IOS, and under the same anesthetic, all patients had either complete resection or debulking of the VMs. Eight patients had complete resolution of their VM and 3 had improvement. Average duration of the combined procedures done under a single anesthetic was 121 min. The POS approach was used for 6 surgical patients with average age 7 years. Sclerotherapy agents used were absolute alcohol or sodium tetradecyl sulfate 3%. All patients underwent complete resection of the VM 24-72 h after sclerotherapy under a separate surgical session. Five patients experienced complete resolution of their VM and one has had further sclerotherapy for recurrent disease. Interventional Radiology suite sclerotherapy times were on average 70 min. Surgical times were on average 142 min. Total combined anesthesia times for the two procedures added together were 212 min. Treatment time was significantly shorter in the IOS group (p = 0.0015).
Conclusions:
Simultaneous IOS at the time of surgical resection has been successful in our hands. IOS has the advantage of a single procedure and decreased cost to the patient. In the era of reducing pediatric exposure to anesthesia, this approach is especially attractive in the pediatric population. As well, at approximately $100/minute cost to the patient to be in either the Interventional Radiology Suite or in the operating room, the reduced length of the procedures seen in the IOS approach results in lower overall cost to the patient.

Vector Operations
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.
Operant Conditioning
Reinforcement in operant conditioning can be positive or negative, both of which serve to increase the likelihood of a behavior. Positive...
