Peripheral Gangrene and Extremity Amputations - Painful Preventable Sequelae of Meningococcal Septicaemia: Case Series Reports.

Extremity gangrene is a fairly common pathology, which complicates systemic vascular and endocrine diseases. Most often, it is encountered in diseases like uncontrolled Diabetes Mellitus, presenting as diabetic foot gangrene, severe peripheral arteriosclerosis with gangrene of the extremity complicating severe uncontrolled systemic hypertension and meningococcal septicaemia with peripheral gangrene. It also occurs in some cases of snake bite as well as frost bite (in regions with extreme cold weather conditions). Some of them present as monolateral extremity gangrene. However, others present as bilateral symmetrical peripheral gangrene (SPG) characterized by bilateral extremity ischaemia resulting in gangrene in which there is no major vascular occlusive disease. There is disseminated intravascular coagulation with the gangrene being considered as a cutaneous marker and some of the patients that survive ultimately require amputation of the affected limb(s) in the severe cases. The mild cases end up losing some of the digits or just exfoliation of the dead cutaneous layer. The effects are generally more severe in the lower limbs than in upper limbs. Notable among these are some of those complicating meningococcal sepsis resulting from peripheral intravascular coagulation. We present here, five patients who presented with varying degrees of peripheral gangrene during an epidemic of meningitis and the treatments that were carried out depending on the severity of their cases.
