Necrotizing fasciitis of the lower limb after venous surgery: cases studies and a review of the literature.

We report 2 cases of necrotizing fasciitis following stripping of the long saphenous vein and phlebectomy of varicose collateral vessels. The first one concerns a 42-year-old man who presented with a left thigh postoperative infection, evolving despite oral antibiotic therapy. Urgent surgical exploration proved an extensive necrosis consistent with necrotizing fasciitis.

Do surgical distal bypasses still play a role in the treatment of critical limb ischemia?

Aim: The treatment of critical limb ischemia is at present very controversial. In fact surgery using different grafts (venous or prosthetic) is in competition with percutaneous angioplasty. Progresses of endoluminal techniques brought certain authors to think that angioplasty is now the first treatment of critical limb ischemia.

Spontaneous renal artery dissection in an otherwise healthy male.

Dissection of a renal artery is rare and, in most cases, associated with underlying arterial diseases. Spontaneous renal artery dissection (RAD) is exceptional. We report the case of a young and otherwise healthy man with an isolated dissection of the right renal artery without any obvious origin.

Pituitary apoplexy after aortic abdominal aneurysm surgery: a case report.

Pituitary apoplexy (PA) occurring after surgery is a rare but life-threatening acute clinical situation following extensive haemorrhage or necrosis within a pituitary adenoma. Pituitary apoplexy has been reported to occur spontaneously in the majority of cases or in association with various inducing factors. One of the pathophysiological mechanism that has been postulated is the fall of arterial blood pressure inducing ischaemia followed by infarction of the pituitary gland.

Emergency endovascular treatment of an acute traumatic rupture of the thoracic aorta complicated by a distal low-flow syndrome.

We report the case of a patient who suffered major trauma following a motorcycle accident that resulted in multiple fractures, bilateral hemopneumothorax, pulmonary contusions, and an isthmic rupture of the aorta with a pseudoaneurysm compressing the descending aorta. This compression was responsible for distal hypotension and low flow, leading to acute renal insufficiency and massive rhabdomyolysis. Due to the critical clinical status of the patient, which prevented any type of open thoracic surgery, endovascular treatment was performed.
