A new study found that clot-busting drugs can save legs as effectively as invasive surgery, reducing the need for open surgical procedures by over 30%. The experimental drug, recombinant urokinase, showed no significant difference in death or amputation rates between surgical and non-surgical patients.
A new virtual tape measure (VTM) prototype enhances microsurgical precision by providing accurate measurements in real-time, overcoming the limitations of traditional operating microscopes. The VTM uses stereo-video images and computer graphics to enable surgeons to make precise calculations throughout operations.
A national trial is underway to determine the effectiveness of removing portions of lungs in patients with severe emphysema. The study aims to find out if the procedure improves long-term outcomes and reduces complications for patients with this debilitating disease.
Researchers at the University of Washington have developed technology to measure forces and torques in surgical procedures, enabling the creation of more realistic simulators. These enhanced simulators could drastically reduce training time and costs while improving performance.
Researchers are testing a robotic port-access technique to assist in bypass surgery, aiming to reduce scarring and hospital stays. The technique uses miniature instruments inserted through small incisions, allowing for precise movements and real-time monitoring.
A new laser-based procedure called transmyocardial revascularization (TMR) has been shown to improve symptoms of severe chest pain in patients with heart disease. After three months, 86% of TMR patients experienced improvement, while only 12% of those treated with medication alone saw results.
A study by UPMC found that minimally invasive heart bypass surgery greatly reduces the number of deaths and complications in very high-risk cardiac patients. The procedure resulted in a mean hospital stay of just 3.9 days, with no patient mortality or strokes after five months.
A recent study found that patients who received the anti-clotting drug ReoPro before angioplasty had a 19% lower risk of needing coronary artery bypass graft surgery within six months. The study, which involved 5,641 patients, also showed significant cost savings in treating heart patients.
A study by Johns Hopkins Medicine reveals that heart surgery patients who experience a stroke have significantly higher mortality rates and longer hospital stays compared to those without a stroke. The average hospital bill for these patients is $45,052, highlighting the need for improved stroke prevention and management.
A new form of gene therapy has been tested to prevent blockages that occur after bypass surgery, with four patients showing successful results. The treatment aims to reduce cell growth and atherosclerosis in grafted vessels, which can fail due to up to 50% of cardiac and leg bypass surgeries.
Researchers found stents lower risk of death, heart attack, and repeat surgery compared to angioplasty for patients with obstructed vein grafts. The study's results suggest a new standard of care for hundreds of thousands of post-bypass patients.
Pediatric heart surgeons are using ultrasound to monitor patients for potential brain damage during and after open-heart surgery. The non-invasive method, Transcranial Doppler, can detect air in the brain circulation when it is ejected from the heart, providing valuable feedback for surgeons.
A mathematical model explains the scientific basis of radical heart surgery, potentially selecting suitable candidates for therapeutic removal of large heart muscle portions. The Batista procedure aims to improve cardiac function by reducing heart size and stress.
Research shows that patient choice significantly impacts surgical rates, with significant variation among geographic units. Shared decision-making strategies can reduce demand for discretionary care by up to 40%, according to studies.
A study in Canada found that waiting times for cataract surgery varied between public and private clinics, with patients perceiving longer waits in the public sector. The majority of physicians practice within the public sector, but some offer faster service due to better resource allocation.
A new laparoscopic technique for kidney removal has been shown to reduce pain, hospital stays, and recovery time compared to traditional methods. The study found that kidneys removed with this technique function as well as those taken out with a large incision.
A Duke neurologist advocates for mandatory reporting of complication rates for carotid endarterectomy to help doctors make informed decisions. Low complication rates are crucial for the procedure's effectiveness in preventing strokes.
Duke University Medical Center is testing a new laser system to pierce blood-carrying channels in ailing heart muscle, showing promising results for eight treated patients. The procedure, known as transmyocardial revascularization (TMR), creates new passageways that increase oxygenation and functional heart muscle.
Mohs surgery has shown promise in preventing melanoma recurrence, particularly in patients with lentigo-maligna tumors. The technique's precision and ability to check surgical margins may provide a better chance of getting rid of tumors and preventing recurrences while conserving tissue.
The new technique allows doctors to find the sentinel lymph node, reducing swelling and side effects. In over 90% of cases, the sentinel lymph node is found, offering women more effective treatment with fewer complications.
A new laparoscopic technique has made kidney donation easier, with reduced recovery time and complications. The procedure involves a small incision and minimizes blood loss, allowing donors to recover in one-third less time compared to traditional surgery.
A major seven-year national study will evaluate the safety and effectiveness of lung volume reduction surgery for people with severe emphysema. Patients selected for the surgery will undergo evaluation and medical therapy at either University of Maryland Medical Center or Johns Hopkins Hospital.
The NHLBI and HCFA have announced a clinical trial to evaluate the safety and effectiveness of lung volume reduction surgery (LVRS) for patients with emphysema. The study aims to determine whether LVRS is a viable treatment option for this population, which currently has limited treatment options.
Researchers found that patients who received chemotherapy and radiation after surgery lived longer than those who did not. Additionally, 7% of patients had inherited mutations in the BRCA2 gene, which is linked to breast and ovarian cancer.
A Johns Hopkins study found that parathyroid gland surgery is more successful and less expensive at academic medical centers with specialized facilities and experienced surgeons. The results showed a cure rate of 97% at high-volume centers compared to 80% at lower-volume hospitals.
A Duke University Medical Center study found that over half of US cardiologists performing angioplasty procedures don't meet recommended minimum standards, leading to increased risk of complications and heart bypass operations. The study confirms the inverse relationship between physician experience and patient outcomes.
Johns Hopkins has started performing the new Port-Access technique for single-graft coronary artery bypasses and heart valve replacement and repair. The procedure is designed to reduce trauma, complications, and pain, resulting in shorter hospital stays and quicker recovery times.
A Johns Hopkins study found that high-risk gastrointestinal surgery patients are less likely to die if treated at hospitals performing more complex procedures, without increased costs. The study's lead author notes that Maryland's unique data collection system contributed to the findings.
Duke University Medical Center surgeons have developed a safe and effective treatment for Zenker's diverticulum, a disabling condition that traps food in the throat. The new endoscopic technique removes the pouch with minimal complications, offering hope to elderly patients with this condition.
A Duke University study of 934 patients found that those treated with bypass surgery or angioplasty had better long-term survival rates compared to medication alone. Patients who underwent revascularization showed a significant increase in three-year survival rates, with bypass surgery resulting in the greatest percentage of survivors.
