Peripheral Arterial Disease (PAD) is a progressive circulatory disorder characterized by the narrowing or blockage of the arteries supplying blood to the limbs, most commonly the legs and feet. When this condition reaches an advanced stage, known as critical limb ischemia, the complete cessation of blood flow results in tissue death. The image provided illustrates a severe manifestation of this disease, where peripheral arterial disease has led to necrosis (gangrene) of multiple toes, evidenced by the blackening and mummification of the tissue due to prolonged oxygen deprivation.

Feline Aortic Thromboembolism (FATE), commonly known as a saddle thrombus, is a devastating condition where a blood clot obstructs the distal aorta in cats. This article provides a detailed anatomical and pathological insight into this critical veterinary emergency, explaining the location and impact of the thrombus on blood flow to the hind limbs and other vital organs. Discover the crucial vascular structures involved and the severe consequences of this life-threatening condition.

The arterial supply of the hand represents an intricate network of vessels crucial for tissue perfusion and function. This complex vascular system provides essential blood supply through multiple anastomoses, ensuring adequate circulation even in cases of partial vessel occlusion. Understanding the arterial anatomy is fundamental for hand surgery, trauma management, and vascular procedures.

The ulnar artery and nerve represent crucial neurovascular structures in the forearm that provide essential blood supply and innervation to the hand. These structures follow a complex course through various anatomical compartments, forming important anastomoses and providing multiple branches. Understanding their precise anatomy is fundamental for surgical procedures, clinical diagnosis, and treatment of upper extremity conditions.

The forearm contains a complex network of arteries and nerves that supply blood and innervation to the muscles, joints, and skin of the distal upper extremity. This intricate arrangement ensures proper function of the hand and fingers while providing redundant circulation through multiple anastomoses. Understanding these neurovascular relationships is essential for surgeons, clinicians, and medical professionals managing upper limb conditions.
