Dr. Wengrovitz studies treatments and outcomes in patients with kidney problems, particularly those on dialysis, as well as conditions affecting blood vessels and arterial blockages. He explores how surgical procedures, medications, and diagnostic methods can lead to better recovery and quality of life for patients. His research includes assessing the effectiveness of surgical revascularization in kidney patients, evaluating the best methods for diagnosing infections in vascular grafts, and investigating how specific medications like cyclosporine can limit complications following vascular injuries. This work is crucial for patients at risk of serious complications from vascular diseases and for improving the quality of care provided to those with chronic kidney issues.
Key findings
In a study involving five patients on dialysis, three were able to stop dialysis completely for up to two years after renal revascularization.
Using thrombolytic therapy preserved arterial wall integrity with an average opening of about 5.63 mm², while balloon catheter thrombectomy caused severe artery damage.
In a study of 184 patients treated for carotid artery blockages, only 6% experienced significant recurrence within 10 months, with higher rates noted in diabetic patients (13.3%).
17% of patients experienced complications after lower leg arterial bypass surgeries, with risk factors including female gender and pre-existing conditions like diabetes.
Cyclosporine treatment at 5 mg/kg significantly reduced blood vessel thickening after injury compared to untreated rats.
Frequently asked questions
Does Dr. Wengrovitz study kidney problems?
Yes, he studies interventions for patients on dialysis, focusing on how surgical procedures can help restore kidney function.
What treatments has Dr. Wengrovitz researched for vascular issues?
He has researched thrombolytic therapy for blood clots and the effectiveness of cyclosporine in preventing blood vessel complications after injury.
Is Dr. Wengrovitz's work relevant for patients undergoing bypass surgery?
Yes, his research addresses infection risks and complications in patients undergoing bypass surgeries, helping to inform better surgical practices.
How does Dr. Wengrovitz's research help diabetic patients?
His studies reveal higher risks of complications for diabetic patients undergoing procedures like carotid artery surgery, allowing for better pre-surgical assessments.
What methods does Dr. Wengrovitz use to detect infections in vascular grafts?
He found that sonication, a technique using sound waves, is the most effective method for recovering bacteria from infected vascular grafts.

Thrombolytic therapy and balloon catheter thrombectomy in experimental femoral artery thrombosis: effect on arterial wall morphology.
1995
Journal of vascular and interventional radiology : JVIR
Wengrovitz M, Healy DA, Gifford RR, Atnip RG, Thiele BL
Plain English This study looked at how different treatments for blockages in the femoral artery, specifically thrombolytic therapy (using a drug to dissolve clots) and balloon catheter thrombectomy (physically removing clots), affect the arterial wall. Researchers found that using thrombolytic therapy maintained the structural integrity of the artery walls, with an average opening of about 5.63 mm², while balloon catheter thrombectomy caused severe damage to the arteries regardless of when it was performed. This research is important because it highlights that thrombolytic therapy can preserve artery health better than the catheter method, which may lead to longer-lasting results for patients.
Who this helps: This helps patients with arterial blockages by informing treatment choices.
Plain English This study looked at five patients on dialysis due to severe kidney problems and assessed whether a surgical procedure to restore blood flow to the kidneys could help them. Out of these patients, three who were only producing small amounts of urine had great results, stopping dialysis for up to two years, while the other two who weren't producing urine remained on dialysis even after the surgery. This research is important because it shows that some people on dialysis could regain their kidney function, which could greatly improve their quality of life.
Who this helps: Patients on dialysis, especially those with certain kidney conditions.
Sonication provides maximal recovery of staphylococcus epidermidis from slime-coated vascular prosthetics.
1991
The American surgeon
Wengrovitz M, Spangler S, Martin LF
Plain English This study looked at different methods for detecting the bacteria Staphylococcus epidermidis in infected vascular grafts. The researchers tested three ways to collect bacteria from graft materials and found that using sonication (a method that uses sound waves) was the most effective, recovering significantly more bacteria than direct pressing or vortexing, especially at lower concentrations. This matters because accurately diagnosing infections in vascular grafts can lead to better treatment and outcomes for patients.
Who this helps: This helps doctors and patients who may have infections related to their vascular grafts.
Wound complications of autogenous subcutaneous infrainguinal arterial bypass surgery: predisposing factors and management.
1990
Journal of vascular surgery
Wengrovitz M, Atnip RG, Gifford RR, Neumyer MM, Heitjan DF +1 more
Plain English This study examined factors that cause infections and other complications in patients undergoing certain types of lower leg artery bypass surgeries. Out of 163 operations performed, 28 patients (17%) experienced complications, with varying severity; 10 had mild issues, 6 had moderate, and 12 had severe problems that threatened their grafts. Key risk factors included being female, using steroids, having diabetes, or having ulcers on the same leg; if these risks were absent, complications were rare.
Who this helps: This research benefits surgeons and patients needing bypass surgery, particularly those at higher risk for complications.
A rational approach to recurrent carotid stenosis.
1990
Journal of vascular surgery
Atnip RG, Wengrovitz M, Gifford RR, Neumyer MM, Thiele BL
Plain English This study looked at 184 patients who underwent surgery to clear blocked carotid arteries, specifically examining how often these blockages returned (recurrent stenosis). They found that 6% of patients developed significant blockages again within about 10 months after the surgery, and those with diabetes or previous symptoms had higher rates of recurrence (13.3% for diabetics vs. 4.5% for non-diabetics, and 11.0% for symptomatic vs. 1.5% for asymptomatic patients). Understanding these patterns helps doctors identify which patients are at higher risk for complications after their surgery.
Who this helps: This benefits patients recovering from carotid artery surgery, especially those with diabetes or previous symptoms.
Cyclosporine inhibits the development of medial thickening after experimental arterial injury.
1990
Journal of vascular surgery
Wengrovitz M, Selassie LG, Gifford RR, Thiele BL
Plain English Researchers studied how cyclosporine affects the thickening of blood vessels after an injury in rats. They found that rats treated with cyclosporine at a dose of 2 mg/kg showed less thickening in their blood vessels compared to untreated ones, while a higher dose of 5 mg/kg consistently reduced thickening over time. This is important because it suggests that cyclosporine can help prevent complications in blood vessels following injury, which may lead to better outcomes for patients at risk of vascular diseases.
Who this helps: Patients recovering from vascular injuries or surgeries.
