Obtained unanimous defense verdict in saddle pulmonary embolus case.
Steve and Cory Tyszka obtained a unanimous defense verdict for a medical malpractice case. This wrongful death case involved allegations of medical malpractice arising from a radiologist’s report of no deep venous thrombosis (“DVT”) on review of a 49-year-old patient’s venous Doppler ultrasound after she presented to the emergency department with calf pain and swelling following a foot fracture. Almost three weeks later, the patient suddenly collapsed and died, and an autopsy confirmed that the death was caused by a massive saddle pulmonary embolus. The case was tried in Maricopa County Superior Court before the Honorable Rodrick Coffey. On January 30, 2024, after a thirteen-day trial, a ten-person jury returned a unanimous defense verdict after deliberating for about two hours.
Obtained a unanimous defense verdict for a medical malpractice case. This case involved allegations of medical malpractice arising from a neurologist’s workup of a patient’s complaints of left-sided symptoms of weakness, shaking, and loss of control. Six weeks after the workup, the patient suffered a stroke and has residual permanent injuries.
Plaintiff alleged that the neurologist was negligent for failing to order vascular imaging, failing to diagnose TIA, failing to properly educate the patient on the significance of a TIA diagnosis, failing to order aspirin therapy, and failing to send the patient to the emergency room upon the patient’s report of new and worsening symptoms. The neurologist maintained that he met the applicable standard of care in all respects, that there was insufficient evidence that Plaintiff would have had a better outcome with earlier intervention, and that Plaintiff’s illicit drug use caused his stroke and would have overshadowed the protective effect of aspirin therapy. Plaintiff claimed permanent loss of function and sensation of his left upper extremity, weakness and spasticity in his left lower extremity, cognitive deficits, pain and suffering, and loss of enjoyment of life. The case was tried in Maricopa County Superior Court before the Honorable Joan Sinclair. After a twelve-day trial, the jury deliberated for only 25 minutes before returning a unanimous defense verdict on April 6, 2023.
Obtained defense verdict after a six-day jury trial in a nerve injury case. Cory, and another JSH attorney, Steve Bullington, obtained a defense verdict in a medical malpractice case that involved allegations arising from a hand laceration caused by a broken light bulb, resulting in nerve injuries to the plaintiff’s dominant thumb. The plaintiff claimed $1 million in damages due to permanent loss of function and sensation of her dominant thumb, disfigurement, and pain and suffering. The case was tried in Maricopa County Superior Court before the Honorable Christopher Coury.
Obtained unanimous defense verdict in $3,000,000 medical malpractice case within minutes following 8-day jury trial. Cory, and another JSH attorney, Russ Skelton, recently obtained a unanimous defense verdict in a medical malpractice case. Their client, a board-certified general surgeon, was facing allegations of medical malpractice arising from the removal of a mass on the left side of the plaintiff’s neck. During surgery, the surgeon discovered a nerve was adhered to the mass, so she removed the nerve from the mass in order to remove the mass. Following the surgery, the plaintiff developed a diffuse left brachial plexus neuritis – nerve inflammation characterized by severe shoulder pain, spotty muscle paralysis, and sensory loss of the shoulder and arm – that resulted in denervation and atrophy of her left deltoid muscle, limiting her ability to use her left arm and shoulder. During the eight-day jury trial, the plaintiff alleged that the defendant was negligent by separating the nerve from the mass, applying too much force to the nerve, and removing the mass in lieu of an intraoperative partial biopsy, which would have shown the mass to be benign. The plaintiff claimed that the surgeon’s alleged negligence caused her to suffer permanent injury and disfigurement to her left shoulder muscles. The surgeon maintained that she met the standard of care in all respects and was adept at handling nerves during routine surgeries such as this one. The surgeon further defended her care with expert testimony that the brachial plexus neuritis was an immune response to the fact of surgery, rather than a result of direct injury to the nerve or to the nerve’s origin during surgery. The plaintiff claimed $3,000,000 in pain and suffering, disfigurement, and loss of enjoyment of life. The case was tried in Maricopa County Superior Court before the Honorable Teresa Sanders. After deliberating for approximately 10 minutes, the jury returned an unanimous defense verdict on November 5, 2019.
Obtained unanimous defense verdict in $8 million wrongful death medical malpractice suit after 15-day jury trial. Cory, and another JSH attorney, Steve Bullington, obtained a unanimous defense verdict in a wrongful death medical malpractice case. Their client, a cardiothoracic surgeon, was facing allegations of medical malpractice arising from an open-heart surgery of an 18-year-old woman following an unrestrained motor vehicle crash. During the 15-day jury trial, Plaintiff alleged that Defendant was negligent by failing to establish bypass before the start of surgery, failing to control the patient’s bleeding during surgery, and negligently placing the patient into deep hypothermic circulatory arrest. Plaintiff claimed that Defendant’s alleged negligence caused the patient to suffer permanent brain injury, which led to the withdrawal of life support and her subsequent death. Defendant maintained that he met the standard of care in all respects, and that the severe cardiac rupture suffered during the patient’s motor vehicle accident was not survivable. Plaintiff claimed $8,000,000 in pain and suffering and loss of consortium. The case was tried in Yuma County Superior Court before the Honorable Larry Kenworthy. After deliberating for approximately one hour, the jury returned an unanimous defense verdict on April 8, 2019.
Obtained defense verdict in 7-day jury trial involving allegations of medical malpractice. Cory and another JSH attorney, Stephen Bullington, defended an orthopedic surgeon against allegations of medical malpractice arising from a total hip arthroplasty procedure. During the 7-day jury trial, Plaintiffs alleged that Defendant was negligent by failing to repair an intraoperative femur fracture, failing to leave the prosthesis in proper anatomical alignment, and failing to recommend revision surgery, causing Plaintiff to suffer anatomical deformity, an inability to walk, and loss of employment. Defendant maintained that he met the standard of care in all respects, and that Plaintiff’s inability to walk was not caused by the surgery but was instead caused by pre-existing osteoarthritis, severe spinal stenosis, and Plaintiff’s failure to adequately engage in physical therapy. Plaintiffs claimed $429,000 in lost wages and at least $1 million in damages due to pain and suffering, loss of consortium, and loss of enjoyment of life. The case was tried in Maricopa County Superior Court before the Honorable Teresa Sanders. After deliberating for less than 45 minutes, the jury returned a defense verdict on December 5, 2018.
Obtained defense verdict in 6-day jury trial involving home healthcare provider. Cory and another JSH attorney, Donn Alexander, represented a home healthcare provider against allegations of abuse, neglect, and negligence relating to the care of an elderly woman with dementia. Plaintiff alleged that Defendants’ caregiver employee was negligent in failing to respond to the elderly woman’s calls for help, causing the woman to fall and break her hip after she got up from her bed without assistance. Plaintiff further alleged that Defendants were negligent in failing to properly train and supervise the caregiver. Plaintiff also sought punitive damages. The Defense maintained that the caregiver’s actions were reasonable, that Defendants exceeded the standard of care in training and supervising the caregiver, and that the woman’s fall was not caused by Defendants’ or the caregiver’s conduct. Plaintiffs claimed $877,874.64 in damages due to pain and suffering, medical bills and expenses, and loss of enjoyment of life. The case was tried in Maricopa County Superior Court before the Honorable Rosa Mroz. After a 6-day trial, the jury returned an unanimous defense verdict on January 30, 2018.

Obtained defense verdict in 7-day jury trial involving allegations of medical malpractice. Cory and another JSH attorney, Cristy Chait, defended a physician against allegations of medical malpractice arising from an endoscopic procedure. The Plaintiff alleged that the procedure was not indicated and that Defendant was negligent in performing the procedure while Plaintiff remained on Plavix, causing Plaintiff to suffer a severe internal hemorrhage and associated complications. Defendant maintained that he met the standard of care in ordering the procedure and continuing Plaintiff’s Plavix. Defendant further claimed that Plaintiff’s alleged ongoing damages were caused by preexisting conditions. Plaintiff claimed approximately $1,000,000 in damages due to pain and suffering, loss of consortium, loss of enjoyment of life, medical bills, and expenses.
Obtained unanimous defense verdict in 8-day jury trial medical malpractice case. Cory and another JSH attorney, Steve Bullington, represented a physician in this medical malpractice case arising from a penile prosthesis exchange procedure. Plaintiff alleged that Defendant was negligent in leaving a fragment of tubing from the removed prosthesis in the Plaintiff’s groin area, causing Plaintiff to suffer an infection, additional surgeries, and loss of employment. Defendant maintained that he met the standard of care in removing the prosthesis and that Plaintiff’s infection was not caused by the fragment. Plaintiffs claimed $900,000 in damages due to pain and suffering, loss of consortium, lost wages, loss of enjoyment of life, medical bills, and expenses.
