Veins of Lower Limbs01:15

Veins of Lower Limbs

1.4K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Varicose Veins I: Introduction

33
Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

59
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 II: Diagnostic Studies and Interprofessional Care

45
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...

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

2.6K
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

56
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...

Summary

Popliteal venous aneurysms (PVAs) are rare but pose risks like deep vein thrombosis. This case highlights successful surgical repair of a PVA with a persistent sciatic vein using tangential aneurysmectomy and anticoagulation.

Area of Science:

  • Vascular Surgery
  • Vascular Medicine
  • Medical Case Reports

Background:

  • Popliteal venous aneurysms (PVAs) are uncommon vascular malformations.
  • PVAs carry significant risks, including deep vein thrombosis (DVT) and pulmonary embolism (PE).
  • Persistent sciatic vein (PSV) is a rare congenital anomaly of the venous system.

Observation:

  • A 70-year-old male presented with left leg heaviness.
  • Previous great saphenous vein ablation was noted.
  • Duplex ultrasound revealed a 3.2 x 2.4 cm popliteal venous aneurysm.

Findings:

  • The patient underwent tangential aneurysmectomy with lateral venorrhaphy for the PVA.
  • Symptoms resolved post-operatively.
  • Perioperative warfarin anticoagulation was administered for 3 months.
  • Follow-up duplex ultrasound at 6 and 18 months showed no recurrence or complications.

Implications:

  • Surgical intervention is recommended for PVAs due to associated risks.
  • Tangential aneurysmectomy with venorrhaphy is an effective and straightforward surgical technique.
  • Combined PVA and PSV presentation requires careful surgical consideration and management.
