Stroke is still one of the most serious health threats globally, especially in low- and middle-income countries where early intervention isn’t always accessible. Carotid artery disease, which can lead to ischemic stroke, is often treatable, but getting the right care to the right patient in time remains a challenge. In Uzbekistan, vascular surgeon Dr. Gulshakhnoza Mukhammadieva is trying to close that gap by introducing minimally invasive procedures that could make stroke prevention faster, safer, and more widely available.
Gulshakhnoza Mukhammadieva
In April 2025, the World Stroke Organization (WSO) launched the Global Stroke Action Coalition to address the projected 50% increase in global stroke deaths by 2050. Without decisive intervention, WSO estimates that the annual economic toll of stroke could reach $1.6 trillion by mid-century, driven by rising medical costs and long-term disability burdens.
As global institutions call for more equitable and timely responses to stroke, local leaders are stepping up. One of them is Gulshakhnoza Mukhammadieva, a specialist in vascular surgery from Tashkent, the capital of Uzbekistan, who has been working to integrate evidence-based endovascular treatments into routine care for patients at risk of stroke. Her work reflects a growing global concern: preventing the most serious outcomes of stroke isn’t only about developing new tools, but about applying what we already know, better and faster. Her research and clinical efforts to improve stroke care earned her the prestigious Aripov Merit Scholarship, awarded by the country’s Ministry of Health, and led to her appointment as a peer reviewer for medicine journals, where her findings have also been published and discussed.
The Changing Face of Vascular Surgery
Vascular surgery remains one of the most demanding and evolving fields of medicine. It deals with diseases of the circulatory system — arteries and veins that can make the difference between life and death, stroke or survival. Among the most critical conditions it addresses is carotid artery stenosis, a narrowing of the arteries that can lead to ischemic stroke, the leading cause of long-term disability worldwide. Carotid artery stenosis is responsible for approximately 15% to 20% of all ischemic strokes. And in the United States alone, over 7 million stroke survivors live with varying degrees of disability, and two-thirds of them experience significant impairments.
Traditionally, these cases have been treated with open surgery, known as carotid endarterectomy. But over the past decade, endovascular surgery — a minimally invasive method involving catheters and stents — has emerged as a promising alternative.
Still, despite its advantages, many hospitals remain hesitant to adopt it broadly, particularly in countries where local data and clinical evidence are scarce. Recognizing this gap between innovation and adoption, Gulshakhnoza began focusing her clinical work on expanding access to endovascular surgery.
“Stroke remains one of the most dangerous vascular complications, and unfortunately, it often leads to irreversible outcomes,” says Gulshakhnoza Mukhammadieva. “That’s why we must not only treat the disease, we must rethink the entire approach to how we intervene, monitor, and prevent recurrence.”
Bridging Research and Clinical Practice
That mindset soon evolved into action. Determined to back it with evidence, she authored a research article titled “Advantages of Endovascular Surgery in Carotid Atherosclerosis,” published in the International Journal of Advance Scientific Research, a peer-reviewed platform for early-stage clinical innovation in developing healthcare systems. While not yet indexed in PubMed, the journal provides visibility for region-specific findings. Her work addresses a pressing question: Can minimally invasive procedures offer a safer, equally effective alternative to open surgery for patients at risk of stroke?
“We had patients who couldn’t risk another open procedure,” Gulshakhnoza recalls. “I wanted to show that endovascular surgery wasn’t just safer — it could be just as effective, even in complex cases.”
In one memorable case, Dr. Mukhammadieva treated a 64-year-old patient who had previously suffered a transient ischemic attack and was ineligible for open surgery due to comorbidities. Using a minimally invasive stenting procedure, her team restored blood flow with no complications. Three months later, the patient had regained full mobility and returned to work, an outcome that underscored the real-world power of applying data-driven protocols.
Drawing on the major international clinical trial, which followed over 3,600 patients across 33 countries, her paper confirms that endovascular stenting and open surgery show similar stroke prevention outcomes, with a procedural risk of just 1% and an annual stroke risk of 0.5%. This data is based on the ACST-2 trial (Second Asymptomatic Carotid Surgery Trial), a large randomized study published in The Lancet, which found no significant difference in long-term stroke rates or overall mortality between stenting and endarterectomy in asymptomatic patients. Yet stenting offered a lower incidence of complications like myocardial infarction and cranial nerve injury, making it a valuable option for high-risk or anatomically complex cases.
Gulshakhnoza also examined data on endovascular thrombectomy in acute stroke care, citing a stark contrast in outcomes: 44–45% of patients treated with thrombectomy regained functional independence at three months, versus 17–18.9% with medication alone. Mortality rates dropped as well, from over 20% to as low as 14%.
But data alone doesn’t change practice. It was her insistence on application, not just publication, that made the difference. “Clinical data is important, but real impact happens when that data changes someone’s decision at the bedside,” Gulshakhnoza explains. “That’s why I pushed for the results to be adopted into practice, not just published.”
While endovascular surgery offers significant advantages, it is not without challenges. In-stent restenosis, where the artery narrows again, occurs in 5–10% of carotid stenting cases within 5 years, potentially requiring further interventions. The procedure’s high costs can strain healthcare systems, particularly in low-resource settings like Uzbekistan. Additionally, endovascular surgery requires specialized training and advanced facilities, which may be limited in developing regions, increasing procedural risks if not adequately supported. Finally, not all patients are suitable candidates due to anatomical or medical constraints, necessitating alternative treatments. These factors underscore the importance of tailored patient selection and robust infrastructure to ensure optimal outcomes.
The surgical approach is now in regular use at the Republican Specialized Center of Surgery in Uzbekistan, where endovascular procedures have become an option for patients who may not be suited for traditional open surgery. This shift has expanded access to less invasive treatment and improved timeliness of care for individuals at risk of stroke.
Her commitment to translating research into bedside practice caught the attention of editors at leading regional journals, earning her an invitation to serve as a peer reviewer for vascular medicine journals, along with publications in regional healthcare journals such as Pediatr, Sogdiana women’s newspaper, and national radio programs. “Research only matters if it reaches the people who can apply it,” she notes. “My priority has always been to turn findings into practical tools that other doctors can actually use.”

Shaping the Future of Stroke Care
As endovascular methods become more accessible, the focus is shifting from novelty to implementation. Gulshakhnoza Mukhammadieva’s work is part of that shift, showing how evidence from research can inform everyday clinical decisions, even outside major medical centers.
She continues to explore new ways to improve stroke prevention, particularly in settings where resources are limited and treatment options remain uneven. Her experience highlights how small adjustments to existing protocols, grounded in local data and patient outcomes, can make a measurable difference.
“When I started, I wasn’t trying to reinvent the system,” Gulshakhnoza says. “I just saw that with the right data and a willingness to act, we could make existing treatments more effective — even in places without advanced infrastructure.”н
For many healthcare professionals, the challenge isn’t discovering new treatments, but finding practical ways to bring proven ones into routine practice. This is where research, persistence, and clinical insight come together — and where stories like hers quietly move the field forward.
Key Takeaway
The tools to reduce stroke risk already exist — the challenge is making sure they reach the people who need them. Dr. Mukhammadieva’s work shows that even without cutting-edge infrastructure, applying evidence-based treatments with consistency and urgency can make a life-saving difference. For healthcare providers everywhere, the lesson is simple: don’t wait for perfect conditions — start improving outcomes with what you have now.
