Research Overview

# A Grieff A Grieff is a vascular surgeon who focuses on improving how patients access and recover from treatments for blood vessel problems. His work spans from developing better surgical techniques—like using robots for chest surgery and optimizing ultrasound planning before dialysis access creation—to identifying why some patients have worse outcomes after procedures and how to prevent those failures, such as ensuring patients attend critical follow-up visits after leg artery procedures or catching rare diseases before transplant surgery.

Robot-assisted thoracoscopic surgery-assisted aberrant right subclavian artery transposition for dysphagia lusoria.

2025

Journal of vascular surgery cases and innovative techniques

Lazinger SM, Gibson M, Grieff AN

Plain English
A woman had an abnormal blood vessel in her chest that was squeezing her esophagus and making it painful to swallow. Instead of performing traditional open-chest surgery, doctors used a robot-controlled camera to perform minimally invasive surgery, moving the abnormal vessel to a different location where it wouldn't compress her esophagus anymore. This case shows that robot-assisted surgery can successfully fix this rare condition with smaller incisions and potentially faster recovery than older surgical methods.

The Role of Physician-Directed Duplex after Brachial Plexus Block in Arteriovenous Fistula Creation.

2023

Annals of vascular surgery

Grieff AN, Lee K, Beckerman MA, Akinsanya J, Rosen SF +3 more

Plain English
Doctors create dialysis access points (tubes connecting arteries and veins) by first mapping veins with ultrasound to find the best location. However, this study found that veins appear smaller on ultrasound than they actually are because patients are dehydrated and cold. When doctors gave patients a nerve block anesthetic before surgery, it relaxed their blood vessels and made veins larger—so the researchers repeated the vein mapping after the nerve block to see if they could find better access locations. In 63% of cases, the second ultrasound revealed better vein options than the first one, and these better-located access points worked just as well as the originally planned locations.

Initial Post-Operative Visit Absenteeism is Associated With Worse Amputation-Free Survival after Tibial Angioplasty.

2022

Annals of vascular surgery

Grieff AN, Syal S, Beckerman WE, Huang S

Plain English
Researchers studied 89 patients who had a procedure to restore blood flow to their lower legs and found that patients who missed their first follow-up appointment after surgery were significantly more likely to miss future appointments and ultimately lose their leg or die within three years. About 60% of patients showed up to their first appointment, but those who didn't attend were more than twice as likely to skip follow-ups later on. This matters because the weeks and months right after this type of surgery are critical for catching complications like infection or blood clots, and staying connected to your medical team during that time directly affects whether you keep your leg.

Late Open Repair of a Massive Common Iliac Artery Aneurysm after Endovascular Failure.

2022

Annals of vascular surgery

Vialonga M, Grieff AN, Beckerman WE

Plain English
A patient who had a minimally invasive procedure to treat an artery aneurysm nine years earlier developed a massive new aneurysm (over 8 inches across) in the same location because the original treatment failed—fluid was leaking into the aneurysm sac and causing it to expand dangerously. The doctors had to perform open surgery to remove the aneurysm and tie off the damaged artery to fix the problem. This case shows that patients treated for large artery aneurysms with minimally invasive procedures need long-term follow-up care, since complications can emerge years later and become life-threatening.

Clinically occult amyloidosis derived from leukocyte chemotactic factor 2 (ALECT 2) with cardiac involvement complicating renal transplantation: case report and literature review.

2021

Cardiovascular pathology : the official journal of the Society for Cardiovascular Pathology

Eletta O, Ali M, Grieff A, Puri S, Matsuda K +2 more

Plain English
Researchers found a hidden disease called ALECT2 amyloidosis in a 72-year-old woman who received a kidney transplant—a protein buildup that had spread throughout her body without being detected beforehand. The protein accumulated not just in her kidneys (where it usually settles) but also in her heart, which caused her heart to stop working after the transplant surgery, leading to her death. Doctors should screen transplant patients for this disease, especially older patients and those from populations where it's more common, because undetected heart involvement can be fatal during surgery.

Complex endovascular repair of type B aortic dissection and predicting left arm ischemia: a case report.

2021

Journal of medical case reports

Kim KG, Grieff AN, Rahimi S

Plain English
Doctors treated a dangerous tear in a patient's main artery (aorta) using a tube-like device inserted through blood vessels, but the device had to block blood flow to the patient's left arm artery. Normally the arm survives this blockage because other arteries take over, but this patient had an unusual artery variant that left his arm without backup blood supply, causing his arm to become dangerously starved of blood days later. The case matters because it shows doctors need to check for this rare anatomic variation before deciding whether patients need additional surgery to restore blood flow to their arms.

Frailty is a Poor Predictor of Postoperative Morbidity and Mortality After Ruptured Abdominal Aortic Aneurysm.

2021

Annals of vascular surgery

Ciaramella M, Kravchenko T, Grieff A, Huang S, Rahimi S +1 more

Plain English
Doctors tested whether a "frailty score"—a measure of a patient's overall weakness and health problems—could predict which patients would die or have serious complications after emergency surgery for a ruptured aortic aneurysm (a life-threatening tear in the main blood vessel from the heart). They found that frailty made almost no difference: patients who were frail and those who weren't had similar death rates (43% vs. 33%) and similar complication rates. The study shows that for this type of emergency surgery, a patient's fragile baseline health matters far less than how sick they are at the moment they arrive for surgery—meaning doctors should focus on what's happening right now rather than assuming elderly or weak patients will definitely do worse.

Concomitant Aorto-Caval Reconstruction for Inferior Vena Cava Leiomyosarcoma.

2021

Annals of vascular surgery

Grieff AN, Hamilton C, Ady J, Beckerman WE, Shafritz R +2 more

Plain English
Doctors treated a 63-year-old man with a rare cancer (leiomyosarcoma) that started in a major vein in his abdomen and had unexpectedly grown into his aorta (the largest artery). They removed the entire tumor and surgically rebuilt both the vein and artery using grafts, using a special bypass technique to keep blood flowing during surgery. The patient recovered well and remained cancer-free a year later with both grafts working properly. This case shows that when this rare cancer involves both the vein and artery, surgeons can successfully remove it and rebuild both vessels if the patient is healthy enough to handle the complex operation.

Anesthesia Type is Associated with Decreased Cranial Nerve Injury in Carotid Endarterectomy.

2021

Annals of vascular surgery

Grieff AN, Dombrovskiy V, Beckerman W, Ventarola D, Truong H +2 more

Plain English
Researchers compared two types of anesthesia used during carotid artery surgery (a procedure to unclog arteries in the neck) in nearly 14,500 patients: general anesthesia, which puts you fully asleep, and regional anesthesia, which numbs only the surgical area. They found that general anesthesia caused nerve damage twice as often as regional anesthesia (2.9% versus 1.7%), while both methods were equally safe in terms of stroke, bleeding, and death rates. Regional anesthesia also had practical advantages—surgery took 22 minutes less time, patients went home sooner, and fewer patients needed to come back to the hospital within 30 days. The researchers conclude that regional anesthesia should be used more often for this surgery because it prevents nerve injury without sacrificing safety.

Extravascular reconstruction of a congenitally absent inferior vena cava.

2020

Journal of vascular surgery cases and innovative techniques

Grieff AN, Shafritz R, Beckerman WE

Plain English
A man was born without the large vein that normally drains blood from the lower body, which caused painful leg ulcers that wouldn't heal despite standard treatment. Doctors created a new drainage path using a special stent (a tiny metal tube) placed outside the existing veins in his abdomen to redirect blood flow from his legs back to his heart. One year after surgery, his leg pain disappeared, his swelling went away, and his ulcers completely healed.

Intraoperative transradial angiography augments safe hysterectomy for uterine fibroids in the setting of ambiguous arterial anatomy: a case report.

2019

Journal of medical case reports

Chandra AA, Grieff AN, Balica AC, Beckerman WE

Plain English
A woman needed surgery to remove a large uterine fibroid (noncancerous tumor), but doctors discovered her blood vessels in that area had an unusual, confusing arrangement that made the surgery unsafe to continue. A vascular specialist used a new imaging technique—inserting a camera through an artery in her wrist instead of her groin—to map out exactly where all her blood vessels were, which allowed the gynecologist to safely complete the surgery without complications. This case shows that using real-time imaging during surgery can help doctors navigate tricky anatomical situations, and that accessing blood vessels through the wrist (rather than the traditional groin approach) offers a safer, less risky option for this kind of emergency guidance.

Use of liposomal bupivacaine in the postoperative management of posterior spinal decompression.

2016

Journal of neurosurgery. Spine

Grieff AN, Ghobrial GM, Jallo J

Plain English
Researchers compared two types of pain-numbing injections used during spine surgery: regular bupivacaine and a longer-acting liposomal version that stays in the body longer. Patients who received the longer-acting version needed about half as much morphine after surgery compared to those who got the regular injection, but this difference was small enough that it could have been due to chance. The study found no clear benefit to using the more expensive longer-acting injection for most patients, though people already taking opioids regularly showed some promise of needing less pain medication with it. The researchers conclude that better-designed studies are needed to determine whether this newer drug actually helps enough to justify its use.

Scavenger receptor class A member 5 (SCARA5) and suprabasin (SBSN) are hub genes of coexpression network modules associated with peripheral vein graft patency.

2016

Journal of vascular surgery

Kenagy RD, Civelek M, Kikuchi S, Chen L, Grieff A +3 more

Plain English
Researchers studied cells from veins that were surgically transplanted to bypass blocked arteries, comparing cells from grafts that failed (narrowed and blocked) versus those that stayed open. They analyzed which genes were active in these cells and found two specific genes—SCARA5 and SBSN—that appear to control networks of other genes linked to graft failure; blocking SCARA5 made cells multiply faster, while blocking SBSN reduced the cells' ability to contract and remodel tissue. This matters because about 30% of these vein grafts fail within a few years, and identifying these key genes could lead to new treatments to prevent that failure and keep grafts open longer.

Learning chronobiology by improving Wikipedia.

2012

Journal of biological rhythms

Chiang CD, Lewis CL, Wright MD, Agapova S, Akers B +43 more

Plain English
University students improved Wikipedia's coverage of chronobiology (the study of biological clocks and time-based processes in living things) by editing and creating 15 pages based on scientific research, making this important information available to anyone searching online. The students spent about 9 hours each reading scientific papers and deciding what information was most important and accurate to include. The project worked: all the pages they edited became top search results, the students learned how to read and evaluate scientific research, and the world now has better access to reliable information about how our bodies work with time and seasons.
