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,...

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...
Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
Veins of Lower Limbs01:15

Veins of Lower Limbs

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 knee,...
Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Area of Science:

  • Vascular Surgery
  • Congenital Malformations
  • Interventional Radiology

Background:

  • Persistent sciatic artery (PSA) is a rare congenital anomaly with an incidence of 0.025-0.04%.
  • PSA is crucial for limb perfusion when the femoral artery system is hypoplastic.
  • Common presentations include aneurysms (25-58%) and complications like thrombosis or compression.

Observation:

  • A 66-year-old woman presented with a painful gluteal mass.
  • Angio-computed tomography revealed a fusiform aneurysmal dilation in the left gluteal region, identified as the left lower gluteal artery.
  • Angiography showed a left aneurysmal PSA with distal thrombosis.

Findings:

  • A combined approach of surgical revascularization followed by embolization was performed.
  • A bypass from the superficial femoral artery to the tibioperoneal trunk was created using a contralateral inverted saphenous vein.
  • The PSA aneurysm was successfully embolized with an occluder, leading to complete exclusion.

Implications:

  • This combined treatment strategy significantly reduces morbidity and mortality associated with PSA.
  • Avoiding a posterior pelvic approach through embolization before revascularization improves patient outcomes.
  • This case highlights a successful minimally invasive management of a complex vascular anomaly.
