Insights

Percutaneous transluminal angioplasty (PTA) for internal iliac artery (IIA) stenosis effectively treats buttock claudication. Most patients experience symptom relief with a high technical success rate and low complication rate.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Endovascular Therapy

Background:

  • Buttock claudication is often caused by internal iliac artery (IIA) stenosis.
  • Endovascular treatment offers a minimally invasive approach for IIA stenosis.

Purpose of the Study:

  • To evaluate the technical feasibility and clinical outcomes of percutaneous transluminal angioplasty (PTA) for internal iliac artery (IIA) stenosis.
  • To assess the efficacy of PTA with and without stent placement in treating buttock claudication.

Main Methods:

  • Retrospective analysis of 34 patients with buttock claudication due to IIA stenosis treated between 2001 and 2011.
  • Angiographic evaluation followed by PTA, with optional stent placement.
  • Clinical outcomes assessed at 3 months, categorizing symptom relief and recording complications.

Main Results:

  • Technical success achieved in 91% (40/44 lesions).
  • Minor complications (intimal dissections) occurred in 3 cases.
  • Complete or partial symptom relief reported in 79% of patients (13% complete, 41% partial) at a median of 2.9 months.

Conclusions:

  • Endovascular treatment of IIA stenosis demonstrates high technical success and low complication rates.
  • The majority of patients (79%) achieve significant symptom relief, making PTA a viable option for buttock claudication.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
Arteries of Lower Limbs01:20

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
