Abstract

Insights

This study assessed renal artery aneurysm (RAA) treatments. In-situ repair proved safe and effective, preserving renal function, while coil embolization was used for specific aneurysm types.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Nephrology

Background:

  • Renal artery aneurysms (RAAs) are rare vascular conditions.
  • Treatment strategies aim to prevent rupture and preserve renal function.

Purpose of the Study:

  • To evaluate the surgical strategies and procedures for treating renal artery aneurysms (RAAs).
  • To assess the safety and efficacy of in-situ repair and coil embolization for RAA management.

Main Methods:

  • Retrospective review of 21 RAA cases (2001-2010).
  • Treatment criteria: RAA > 2 cm and/or symptomatic.
  • Surgical repair (aneurysmectomy with in-situ repair) was the primary strategy.
  • Coil embolization reserved for narrow-necked, saccular, extraparenchymal aneurysms.

Main Results:

  • 15 patients underwent aneurysmectomy with in-situ renal artery reconstruction.
  • 5 patients were treated with coil embolization.
  • 1 patient required an unplanned nephrectomy.

Conclusions:

  • In-situ repair is a safe and minimally invasive option for RAA treatment.
  • The transperitoneal approach with subcostal incision allows safe access for RAA repair.
  • Treatment resulted in acceptable outcomes and preserved renal function.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
