Summary
A rare congenital artery anomaly, persistent sciatic artery (PSA), caused acute limb ischemia in a patient. Prompt diagnosis and treatment led to a positive outcome, highlighting the importance of recognizing this condition.
Area of Science:
- Vascular Surgery
- Congenital Arterial Anomalies
Background:
- Persistent sciatic artery (PSA) is a rare congenital anomaly with potential for severe lower limb complications.
- PSA can lead to critical limb ischemia and amputation if not promptly managed.
Observation:
- A middle-aged woman presented with acute limb ischemia superimposed on chronic ischemia.
- The condition was found to be caused by thrombotic occlusion of a persistent sciatic artery.
Findings:
- Timely investigation and treatment of PSA thrombosis resulted in a favorable clinical outcome.
- The case highlights the importance of considering PSA in the differential diagnosis of lower limb ischemia.
Implications:
- Awareness of PSA's embryologic origin, presentation, and management is crucial for clinicians.
- Early diagnosis and intervention can prevent limb loss in patients with PSA-related complications.

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...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

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...
