AI Article Synopsis
- The study researched the safety and effectiveness of a minimally invasive procedure called MIPTRS for treating renal artery stenosis in patients with low kidney function (eGFR ≤ 45 mL/min).
- The procedure involved advanced techniques to reduce complications, such as using a small amount of contrast agent and special devices for guidance.
- Results showed that while creatinine levels remained stable, there was a significant improvement in kidney function (eGFR), indicating that MIPTRS can be a safe and beneficial option for patients with compromised renal health.
Article Abstract
Background: Minimally invasive percutaneous transluminal renal artery stenting (MIPTRS) is a method that prevents complications to the greatest extent possible. The present study aimed to investigate the safety and efficacy of MIPTRS performed in cases of renal artery stenosis with an estimated glomerular filtration rate (eGFR)≤45mL/min.
Methods: Cases of patients who underwent MIPTRS at our hospital between December 2010 and June 2015 in whom eGFR was ≤45mL/min were retrospectively analysed. MIPTRS was performed as follows: 1) using a 4Fr sheathless guiding catheter in a trans-radial approach and 2) using a guiding catheter non-touch technique. The amount of contrast agent used was maintained at ≤10mL with 3) carbon dioxide enhancement and 4) intravascular ultrasound guide stenting, and 5) a distal protection device was used.
Results: MIPTRS was performed in 22 patients (32 lesions). The pre-MIPTRS creatinine level and eGFR were 2.01±0.88mg/dL and 29.2±9.0mL/min/1.73m, respectively. On postoperative day 2, they were 1.78±0.73mg/dL and 35.1±12.3mL/min/1.73m; at 1month after the procedure, they were 1.80±0.74mg/dL and 33.3±12.3mL/min/1.73m. Creatinine level did not change significantly, but eGFR was significantly elevated after versus before the procedure, both 2days later (p<0.01) and 1month later (p<0.05).
Conclusion: The results of this study demonstrated the usefulness of MIPTRS for protecting renal function. This method can be safely used in patients with decreased renal function.

Introduction: Hypertension is among the most significant non-communicable public health issues worldwide. High blood pressure, or hypertension, has been associated with severe health consequences, including death, aneurysms, stroke, chronic renal disease, eye damage, heart attack, heart failure, peripheral artery disease, and vascular dementia. Consequently, this study aimed to investigate the predictors linked to survival time and the progression of blood pressure measurements in hypertensive patients.

Purpose: Takayasu arteritis (TAK) is a rare form of chronic vasculitis that is common in Asian female. As TAK predominantly affects young female with a longer life expectancy than those with atherosclerotic diseases, assessing the specific long-term outcomes of TAK treatment is important. Therefore, this study aimed to evaluate the long-term outcomes and post-procedural complications of surgical and endovascular treatment for TAK.

We demonstrate an aberrant ramification pattern of the renal and testicular vessels. On both sides, the anterior and posterior renal veins emerged from the renal. On the right side, the anterior renal vein collected the right testicular vein and drained into the inferior vena cava, while the posterior one directly drained into the inferior vena cava.
