This maritime negligence case arose from an accident involving Joseph Sylvester that occurred on September 23, 2021. In 2021, Talos operated the South Marsh Island 130 (“SMI 130”) field, located in the Gulf of Mexico on the Outer Continental Shelf. Sylvester, employed as a crane mechanic by Gulf Crane Services, Inc. (“GCS”), was assigned to work for Talos on its offshore production platforms in the SMI 130 field between April and October 2021. On the day of the accident, Sylvester claimed he sustained personal injuries at approximately 9:30 a.m. while being transferred in a personnel basket from the M/V Miss Peggy Ann (“the vessel”) to Talos’s SMI 130 platform.
He explained that when the crane operator, Brian Spears, lifted him in the basket, the basket swung rapidly, causing it and Sylvester to slam violently into a Connex box on the vessel’s deck. Sylvester contended that the negligent operation of the SMI 130 platform crane by Spears caused or contributed to his injuries.
Extent of his injuries
As a result of the incident, Sylvester sustained serious injuries, including damage to his hip, back, and legs. He suffered severe pain and swelling in his hip, thigh, and leg and received a diagnosis of a blood clot. In October 2021, he was diagnosed with deep vein thrombosis (“DVT”) and underwent a surgical procedure to remove the blood clots. He was placed on two powerful blood thinners to prevent the recurrence of clots. Despite these surgeries and ongoing medication, his leg pain worsened. In February 2023, an ultrasound revealed new blood clots in his left leg, leading to swelling and severe pain.
Defendants retained Chad Domangue as an expert in neurology and pain management. At their request, Domangue conducted a physical examination of Sylvester, reviewed his medical records, and determined the cause of his severe leg pain which continued despite receiving extensive treatment. Following his examination, Domangue expressed the medical opinion that all of Sylvester’s symptoms were related to his vascular abnormalities and not his lumbar spine. However, Plaintiffs contended that this statement, along with others, exceeded the scope of Domangue’s expertise.
Neurology and Pain Management Expert Witness
Dr. Chad M. Domangue, M.D. has exhaustive training in identifying and administering treatment for conditions that trigger severe and chronic pain and decreased functionality as an Interventional Neurologist and Pain Management Specialist.
He is double board-certified in Neurology and Pain Management and is board eligible for Clinical Neurophysiology. These distinct credentials allow Domangue to assess and furnish his opinion as both a pain specialist and a neurologist. It displays a tangible demonstration of his deep commitment to providing the best possible care for his patients.
Discussion by the Court
In this case, Plaintiffs raised several arguments under Daubert and Rule 702 regarding the reliability of the vascular opinions provided by Domangue. They asserted that his opinions were unreliable for several reasons: (1) they lacked specialized knowledge that would assist the trier of fact in understanding the evidence; (2) they were not based on sufficient facts or data; (3) they were unsupported by reliable principles and methodology; and (4) there was no evidence to support the reliability of his opinions.
In response, Defendants contended that Plaintiffs misunderstood the fields of neurology and pain management and the methodology employed by Domangue in forming his opinions. Physicians specializing in neurology and pain management frequently create differential diagnoses to assess whether a patient’s vascular conditions contribute to their pain or other symptoms.
Vascular Issues as a Potential Causal Factor for Sylvester’s Prolonged Pain
As the Court examined the arguments, it determined that Domangue’s opinion regarding vascular issues as a potential causal factor for Sylvester’s prolonged pain was appropriate. It was reasonable for Domangue, as an attending physician, to consider a vascular abnormality as explanations for Sylvester’s persistent symptoms and swelling.
Qualifications
Despite Plaintiffs’ claims that Domangue lacked the qualifications to opine on vascular issues and had no factual support for his opinions, Defendants argued that he was well-equipped to evaluate the impact of vascular conditions on his patients. The Court supported this view, noting Domangue’s extensive training. Domangue participated in an internship program at the Medical Center of South Carolina, Charleston, South Carolina. The first year of the program was internal medicine, which included training in vascular issues. Additionally, from 2005 to 2007, Domangue was a resident in the neurology department at the University of Virginia, where he participated in and was trained in the stroke program. In this program, he received specific training in the diagnosis and care of vascular conditions.
Reliable Methodology
Domangue’s report demonstrated his thorough evaluation of Sylvester’s case. He reviewed medical records, including imaging studies and narrative records, and conducted a physical examination. From this, he arrived at a differential diagnosis, which Defendants argued is a reliable methodology. A differential diagnosis involves a systematic process where medical practitioners identify the most likely cause of a patient’s symptoms and then evaluate all the possible causes of the condition based on the history of the patient’s symptoms, his medical records as well as physical examination and laboratory testing results.
In this case, Domangue explained that, as a neurologist and pain management specialist, he was tasked with evaluating how the presence and effect of vascular conditions might contribute to Sylvester’s complaints of pain and physical limitations. He did not propose treatments for Sylvester’s blood clots; instead, he diagnosed the worsening venous issues as the source of the pain. After starting with a physical examination, medical history, and imaging studies, Domangue ruled out lumbar injuries as a cause of Sylvester’s symptoms. He therefore ruled in vascular issues as a potential cause of Sylvester’s clotting.
Held
The Court denied the Plaintiffs’ motion to exclude the opinions of Chad Domangue.
Key Takeaway:
The Court concluded that the arguments against the admissibility of certain medical opinions lacked sufficient grounds for exclusion. It emphasized the importance of evaluating the methodologies used in forming medical opinions, particularly the ones consisting of a differential diagnosis, which followed a patient-specific process of elimination in order to identity the “most likely” cause of a set of signs and symptoms from a list of possible causes. The Court acknowledged that challenges to these opinions would be better addressed through cross-examination instead of exclusion.
