Complications are broadly defined as outcomes that differ from the norm and can be described as general, specific and technical. Common general complications following spinal surgery are gastrointestinal complications and urinary tract infections. Specific complications of spinal surgery include: haematomas, surgical site infections, nerve root injury, dural tears and progressive myelomalacia. Technical complications are generally secondary to implant placement, dislocation of the implant or instrument-related.
In a large prospective study on morbidity and mortality of major adult spinal surgery (Street et al., 2012), 87 percent of patients had at least one documented complication:
*Two dogs (2/8; 25%) undergoing AA stabilization died (1 cardiac arrest, 1 euthanized following cardiac arrest and successful resuscitation). Two dogs (2/38; 5.2%) undergoing cervical ventral slot procedures were euthanized following anesthesia and surgery for complications related to aspiration pneumonia.
*In our study we found a higher incidence of seizures after cranial myelography, higher incidence of gastrointestinal (GI) complications particularly in paraplegic dogs, and a higher risk of death in patients after the SLOT surgery. The occurrence of cystitis was not significant (p = 0.5524, p = 0.1655, respectively).

In a study by Dowdle and colleagues (Dowdle et al., 2003), endoscopy was used to determine the prevalence of subclinical gastroduodenal ulceration in 30 Dachshunds undergoing decompressive surgery for acute intervertebral disc prolapse. An overall prevalence of 76 percent was calculated. Ulcerogenic medication administered prior to admission did not appear to influence the prevalence. Urinary tract infection
Urinary tract infection (UTI) is a common complication in dogs with acute intervertebral disc extrusion (IVDE). The prevalence for development of UTI in 25 dogs treated surgically has been evaluated. In one study (Olby et al., 2010), presence of UTI over the three-month period was correlated to potential risk factors. Ten dogs (38 percent) developed 12 UTIs over the three-month period, with the majority occurring between the first and sixth week. Sixty percent of the UTIs were occult; haematuria in the absence of pyuria or UTI was a common finding in the perioperative period. Sex, breed and ambulatory status influenced the risk of developing a UTI. Females, Dachshunds and paraplegic dogs were at higher risk. Surgical site infection
The surgical site infection (SSI) rate in dogs undergoing hemilaminectomies or laminectomies for thoracolumbar disc herniation or lumbosacral disease, without use of perioperative antibiotics, has been retrospectively evaluated during a two-year period (Dyall and Schmökel, 2018). All incisional complications within 30 days were recorded and divided into superficial, deep (Figure 1) or organ/ space infections. This research study included 154 consecutive hemilaminectomy and laminectomy procedures. One superficial wound infection was recorded and treated with antimicrobials. Overall, the SSI rate was 0.6 percent, while the expected SSI rate in clean operative wounds in dogs and cats is 2.0 to 4.8 percent. The SSI rate in human spinal surgery is 0.7 to 4.3 percent.Myelomalacia
Progressive myelomalacia (PMM; Figures 2 and 3) is a catastrophic disease associated with acute IVDE. The onset and progression of clinical signs of PMM has been examined retrospectively in 51 dogs, 18 with histopathologically confirmed PMM and 33 presumptively diagnosed based on clinical signs (Olby et al., 2017). Five dogs had two sites of disc extrusion, giving 56 extrusions in total. Data on nature and progression of signs were extracted. Twenty-four of 51 dogs were Dachshunds. Planning poker app free. T12–T13 was the most common site of disc extrusion (12 of 56), and 18 mid-to-caudal lumbar discs (between L3 and L6) were affected.
Onset of PMM signs ranged from present at first evaluation (17/51) to
five days after presentation, with 25 of 51 cases developing signs
within 48 hours. Progression of signs from onset of PMM to euthanasia or
death, excluding seven cases euthanised at presentation, ranged from 1
to 13 days, with 23 being euthanised within three days. Nonspecific
systemic signs were documented in 30 of 51 dogs.
The majority of dogs developing myelomalacia do so within two days of presentation, with euthanasia commonly occurring within another three days. The onset can be delayed up to five days after presentation, with progression to euthanasia taking as long as two weeks. Mid-tocaudal lumbar discs might be associated with an increased risk of PMM.
Neurological deterioration Ventral Slot Surgery Dog Complications Icd 10 Code
Early post-operative neurological deterioration is a wellknown complication following dorsal cervical laminectomies and hemilaminectomies in dogs. Medical records of 100 dogs that had undergone a cervical dorsal laminectomy or hemilaminectomy were assessed retrospectively in one study to evaluate potential risk factors (Taylor-Brown et al., 2015). Multiple variables were evaluated and the outcome measures were neurological status immediately following surgery and duration of hospitalisation.
Diagnoses included osseous associated cervical spondylomyelopathy (OACSM), and acute intervertebral disc extrusion in 72 percent of the dogs. Overall, 54 percent were neurologically worse 48 hours post-operatively. Statistical analysis identified four factors significantly related to early post-operative neurological outcome. Diagnoses of OACSM or meningioma were considered the strongest variables to predict early deterioration, followed by higher neurological grade before surgery and longer surgery time.
This information can aid in the management of expectations of clinical colleagues and owners with dogs undergoing spinal surgical procedures. The use of prophylactic anti-ulcer medication in spinal surgery patients is suggested. Dogs with thoracolumbar IVDE should be routinely monitored for UTI with urine culture regardless of urinalysis results. The low incidence of SSI suggested reconsideration of routine perioperative antibiotic prophylaxis in dogs undergoing laminectomy procedures.
Ventral Slot Surgery Dog Complications SymptomsIntroduction
Once a patient with a cervical intervertebral disc herniation has been deemed a surgical candidate, the surgeon is faced with several options on how to operate. A general rule of thumb is to establish a goal of mass (disc) removal, as this is ultimately the decompressive element of surgery. A challenging decision comes when the herniated disc material is lateralized and residual material may remain in the intervertebral foramen without a carefully planned and executed approach. In these instances, it is not always clear which approach will best allow for spinal cord and nerve root decompression. Also challenging is the current lack of biomechanical studies comparing the instability created by these different approaches or the clinical significance of any such instability.
Ventral approach and ventral slot
The ventral slot is one of the most widely used approaches for spinal cord decompression in veterinary patients with cervical intervertebral disc herniation. Using this procedure, it is very easy to access displaced disc material located within the ventral aspect of the vertebral canal (see Figure 30.1). This procedure was first described in dogs as an alternative to the dorsal approach for laminectomy or hemilaminectomy [1]. Either a ventral midline dissection or a paramedian dissection to the ventral cervical spine can be used. For the midline approach, a ventral midline incision is made and the approach is continued on the midline between the paired sternothyroideus and sternohyoideus muscles. The trachea, carotid sheath, and esophagus are retracted to the left to expose the paired longus colli muscles immediately ventral to the vertebrae [2]. For the paramedian approach, a ventral midline skin incision is made, but the dissection is continued paramedian, between the right sternocephalicus muscle and right sternothyroideus muscle [3]. The sternohyoideus and sternothyroideus muscles, trachea, esophagus, and carotid sheath are all retracted to the left. The paramedian approach may make it less likely to disrupt tracheal blood supply, the right carotid sheath, and the recurrent laryngeal nerve [3]. With either of these ventral approaches, the correct site for the ventral slot is identified by palpating the large transverse processes of C6 and the ventral midline process of C1 and then, using these landmarks, palpating the caudal ventral processes of the cervical vertebrae that mark each interspace between C2–C3 and C7–T1. It is important to review preoperative imaging to identify any anatomical variations in vertebral formula or transitional vertebrae. The longus colli muscle is divided along the midline to expose the ventral aspects of the vertebral bodies and intervertebral disc. A high-speed burr is used to create an opening (“slot”) in the vertebral bodies, centered over the disc space and extending to the dorsal longitudinal ligament. Due to the angulation of the intervertebral disc and end plates, the slot should be centered initially over the caudal aspect of the cranial vertebra rather than over the ventral annulus, with the caudal extent of the slot at the cranial end plate of the caudal vertebra. As the burring is continued dorsally, the slot will end up being centered on the dorsal aspect of the intervertebral disc. This will help avoid disruption of the paired vertebral venous plexus, which deviates laterally over each disc space, and thus reduce the risk for hemorrhage, which can be quite severe and interfere with completion of the disc removal and decompression. After penetrating the dorsal cortex of the vertebral body, the dorsal longitudinal ligament is separated or excised, and the herniated disc material is removed from the vertebral canal using instruments such as a right-angle nerve root retractor passed gently along the ventral aspect of the vertebral canal.Ventral Slot Surgery Dog Complications Icd 10
Complications of the ventral slot include hemorrhage from the vertebral venous plexus, instability of the vertebral bodies, erosion of the dorsal tracheal membrane from sutures in the longus colli, and poor decompression due to the limited visibility through the slot created [1, 4–7]. The reason the ventral approach is confined to a slot, and not a larger window that would permit more visualization and room for manipulation of instruments, is because of the potential for vertebral collapse and fracture from an overly aggressive degree of bone removal from the vertebral bodies. This is less a problem in human anterior approaches owing to the short but wide morphology of cervical vertebrae in that species, compared with the long but narrow cervical vertebrae in dogs. The small size of the resultant windows created in dogs, along with the small overall size of many veterinary patients, means that there is very little working room for either visualization or manipulation of instruments in our patients. So while the ventral approach provides the most direct route to ventrally herniated disc material, and without the degree of dissection required for dorsal approaches, it comes with the trade-off of very limited working space. The use of magnification and good lighting can mitigate some of these inherent limitations, but this remains one of the limiting aspects to this approach in dogs.
