Atticus had an appointment with ENT today to discuss his upcoming interstitial laser treatment. We had a lot of questions going into the appointment, and some were answered, but because of the nature of lymphatic malformations, no doctor can ever answer every question. There will always be unknowns, and that is just something that me and Brian have learned to accept and be OK with.
I had done some research on interstitial lasering of venous malformations, so I went into the appointment knowing a little bit. First, I have to explain that I’ve been calling Atticus’ malformation a lymphatic malformation, which is sort of the general term, but his actually has a large venous component and probably only a small lymphatic component. I guess technically, it is a mixed venous lymphatic malformation. There’s a whole classification system that was developed by Mulliken and Glowacki in 1982, if you’re interested.
Table 1.: ISSVA Classification of Vascular Anomalies
Vascular Tumors | Vascular Malformations | ||
Simple | Complex | Flow | |
Hemangioma Pyogenic granuloma Hemangiopericytoma |
Capillary (CM) Venous (VM) Lymphatic (LM) |
Lymphatico-Venous (LVM) Capillary-Lymphatico-Venous … |
S L O W |
Hemangioendothelioma Tufted angioma |
Arterial Arteriovenous (AVM) |
Capillary-Arterio-Venous … |
F A S T |
I’ll try to simplify the classification. Vascular anomalies are a heterogeneous group of congenital blood vessel disorders. These can be broken down into vascular tumors (the most common vascular tumor being hemangioma) and vascular malformations. Vascular malformations can be lymphatic, capillary, venous, arteriovenous, or some combination of these.
Because Atticus’ malformation is venous lymphatic and goes deep into the tissue of his tongue, he is a candidate for interstitial laser surgery, which penetrates deeper into the tissue than a surface laser does. Atticus is scheduled for his first treatment of this type on January 29th. They will use an Nd: YAG laser and will enter the tongue with a catheter, which the laser will pass through. They will probably laser two spots on each side of the tongue for a total of four spots. Atticus’ team of doctors has not performed this specific type of laser treatment before, so they will be conservative on the first treatment and be more aggressive in future treatments, after they see how he responds.
No doctor has done a ton of these treatments because it is just not very common. However, Dr. Gresham Richter in Arkansas has probably done more than any other doctor. We are lucky that Atticus’ doctors have a direct connection to Dr. Richter and are consulting with him on the specifics of the procedure. Atticus’ team of doctors feels comfortable and confident in their abilities to perform the procedure.
We asked about risks of the treatment. The major ones seem to be internal bleeding in the tongue after the procedure, or the possibility of hitting a nerve in the tongue. There are really no new risks to this procedure over any other procedure Atticus has already had. We are expecting swelling, which will affect eating, so we will see how to deal with that after the procedure. Because Atticus has a trach, swelling affecting the airway will not be an issue.
The most we can hope for is some shrinkage to the tongue. We are not sure how much shrinkage to expect. They are going to be conservative in their first treatment, so really, only time will tell. We have to be patient and positive – two qualities that we quickly learned to embrace after Atticus was born. There are no quick fixes or easy answers when dealing with vascular malformations. At this point we are all too familiar with the answer of “I don’t know” from doctors. While this can be unsettling, we appreciate the honesty of Atticus’ doctors. For now, we just take it one day at a time, stay positive, and hope that this treatment will make a difference.
