DSA Goes Live at Gansu Wuwei Cancer Hospital Lanzhou Heavy Ion Center

Precision Intervention Adds a Powerful Tool! DSA Goes Live at Gansu Wuwei Cancer Hospital Lanzhou Heavy Ion Center​

Recently, the Gansu Wuwei Cancer Hospital Lanzhou Heavy Ion Center held the startup ceremony for its Digital Subtraction Angiography (DSA) system. The official launch of this cutting-edge device, hailed as a "super navigation system for the river of life," marks a critical step for the hospital in deeply integrating "heavy-ion precision radiotherapy" with "minimally invasive interventional therapy" to build a comprehensive cancer diagnosis and treatment system. This advancement injects new technological momentum into enhancing the region's capacity for treating major diseases.

Synergizing Strengths to Forge a New Paradigm in Cancer Care​

The Gansu Wuwei Cancer Hospital Lanzhou Heavy Ion Center has achieved groundbreaking successes in tackling refractory tumors with its internationally leading heavy-ion radiotherapy technology. The introduction of the DSA system represents a strategic upgrade and fusion of diagnostic and therapeutic capabilities. It will form a powerful technical synergy with the heavy-ion system, PET-CT, and other advanced equipment, collectively establishing a comprehensive, one-stop solution for tumors—spanning from precise diagnosis and minimally invasive intervention to cutting-edge radiotherapy.

If DSA is the "spearhead force" that delves deep into lesions, then heavy ions serve as the "strategic heavyweight" for destroying tumors. The collaboration between the two means that not only can tumors be subjected to "stereotactic precision strikes," but the "battlefield" can also be preemptively cleared and "supply lines" controlled through minimally invasive methods, enabling the development of more optimized and personalized comprehensive treatment strategies for patients.

Precise Lesion Detection, Minimally Invasive Intervention for Wellness​

The Digital Subtraction Angiography machine can be called the "penetrating eyes" of modern medicine. By injecting a contrast agent and utilizing computer-based high-definition imaging, it can render real-time, dynamic 3D "maps" of human blood vessels. Its clinical value is manifested in two core areas: diagnosis and therapy.

• In diagnosis, it acts as a "keen-eyed scout," capable of clearly revealing coronary artery blockages, the risks of aneurysms, arteriovenous malformations, and points of bleeding with unknown causes, leaving lesions hidden deep within the body with nowhere to hide.

• In therapy, it functions as a "highly skilled engineer." Under its real-time guidance, doctors can maneuver slender catheters directly to the lesion site to perform a series of high-difficulty minimally invasive interventional procedures: clearing blocked coronary arteries and implanting stents to restore "vital pathways"; sealing off dangerous aneurysms to defuse "ticking time bombs"; embolizing the blood-supply arteries of tumors like liver cancer to "starve" cancer cells; and dissolving acute embolic thrombi to buy precious time for saving patients with myocardial infarctions or cerebral infarctions.

Leading the Frontier with Minimally Invasive Techniques, Ensuring a Quality Medical Journey​

Compared to traditional open surgery, interventional therapy guided by DSA offers significant advantages: minimal trauma, high precision, enhanced safety, and rapid recovery. Patients typically undergo procedures through just a tiny puncture point, which greatly reduces pain, shortens hospital stays, and speeds up postoperative recovery, fully reflecting the trend towards minimally invasive and patient-centered development in modern medicine.

The activation of this DSA system has not only substantially strengthened the comprehensive capabilities of the Gansu Wuwei Cancer Hospital Lanzhou Heavy Ion Center in the field of tumor intervention but also significantly boosted its emergency response capacity for conditions like cardiovascular and cerebrovascular diseases, leading to an overall enhancement of the hospital's comprehensive medical service capabilities.

With the formal commissioning of this "super navigation system," the Gansu Wuwei Cancer Hospital Lanzhou Heavy Ion Center, now driven by the dual cores of "Heavy Ions" and "Intervention," is charting a clearer and more reliable "health navigation chart" for the people in Northwest China, inaugurating a new chapter in precision medicine.

Minimally Invasive Intervention Department​

The Minimally Invasive Intervention Department at the Lanzhou Heavy Ion Center of Gansu Wuwei Cancer Hospital was established under the leadership of President Wang Junjie, with the involvement of renowned minimally invasive tumor therapy experts from within and outside the province. The department specializes in minimally invasive interventional therapies for tumors, complementing radiotherapy to form a comprehensive cancer treatment system.

The department is equipped with 30 patient beds, offering a comfortable and fully-equipped inpatient environment. It is outfitted with advanced medical equipment, including a GE digital subtraction angiography (DSA) machine, a large-bore spiral CT scanner, microwave radiofrequency thermocoagulation machines, pulsed radiofrequency machines, radioactive seed implantation and planning systems, high-definition ultrasound machines, and regional circulatory hyperthermic perfusion therapy systems. The department performs a wide range of minimally invasive procedures under DSA, CT, and ultrasound guidance. It also provides minimally invasive treatments for common vascular diseases such as great venous varicosity, arteriovenous fistula, and diabetic foot.
