Summary
Venous stenting is safe for women of childbearing age, with low complication rates during pregnancy. Anticoagulation is recommended due to increased venous thromboembolism risk.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Obstetrics & Gynecology
Background:
- Venous stenting treats iliofemoral venous outflow obstruction.
- Pregnancy increases hypercoagulability, raising concerns for stent use in women of childbearing age.
Purpose of the Study:
- To systematically review the performance and safety of venous stents in women who subsequently became pregnant.
Main Methods:
- Systematic review of studies up to April 2023.
- Data collected on demographics, indications, stent characteristics, complications, VTE incidence, medical management, and follow-up.
- Included 76 women with 87 subsequent pregnancies after stenting.
Main Results:
- Low complication rates: 1.14% stent occlusion, 2.29% asymptomatic thrombus, 2.29% permanent compression.
- Patency loss occurred due to inadequate anticoagulation in an antiphospholipid syndrome patient.
- Permanent compression occurred in an arterial stent and a specific venous stent type.
Conclusions:
- Venous stents demonstrate good performance and safety during pregnancy.
- Anticoagulation therapy is prudent for all stented patients due to elevated VTE risk and low bleeding risk.

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

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...

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

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...
