Insights

Successful intra-arterial thrombolysis for peripheral arterial occlusions depends on good runoff and intrathrombotic infusion. Other factors like patient sex, age, and symptom duration had less impact on treatment success.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology

Background:

  • Peripheral arterial occlusions pose significant clinical challenges.
  • Intra-arterial thrombolysis is a key treatment modality.

Purpose of the Study:

  • To identify factors associated with successful intra-arterial thrombolysis.
  • To evaluate the efficacy of streptokinase and tissue plasminogen activator (tPA) in peripheral occlusions.

Main Methods:

  • Retrospective analysis of 58 patients undergoing intra-arterial thrombolysis.
  • Comparison of outcomes based on patient demographics, symptom characteristics, occlusion details, and treatment parameters.
  • Administration of continuous intra-arterial streptokinase or tPA.

Main Results:

  • Overall successful lysis rates were 59% with streptokinase and 75% with tPA.
  • Good runoff was significantly associated with successful thrombolysis (p < 0.01).
  • Intrathrombotic catheter position was crucial for successful lysis; catheter position above occlusion yielded poor results.

Conclusions:

  • Good runoff and intrathrombotic infusion are essential for successful immediate outcomes in peripheral arterial thrombolysis.
  • tPA demonstrated a higher success rate compared to streptokinase.
  • Optimizing catheter placement and assessing runoff are critical for treatment planning.

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...

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...

Peripheral Artery Disease V: Postoperative Nursing Management

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...

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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
