[Multidisciplinary approach to pain and institution of analgesic treatment].

Pain is a complex sensory response to tissue damage but also mental functioning. Patients with chronic pain require an interdisciplinary model of care after a careful evaluation and understanding of pathophysiology. Therapy may include medications, nerve blocks and behavioural interventions.

[Celiac plexus block: value of x-ray computed guidance].

Celiac plexus block is a good alternative of pain treatment in upper abdominal pain. Neurolysis of the celiac plexus by the percutaneous posterior route used CT guidance in 8 patients. Pain relief was obtained in 5 of 7 patients (70 per cent); no complication occurred.

[Postoperative cervicofacial subcutaneous emphysema].

Two cases of post-operative subcutaneous emphysema are reported. After excessive airway pressure, air or anaesthetic gases may spread to the neck, mediastinum, abdomen or pleural cavity. Pathogenesis and mechanisms are discussed.

Visceral revascularization by anastomosis between the left renal and Drummond's marginal artery.

Drummond's marginal artery was revascularized by anastomosis with the left renal artery in two patients with visceral ischemia due to occlusion of the celiac and superior mesenteric arteries. In this manner, the authors avoided entering an infected abdominal cavity, interposition bypass and aortic clamping. In both cases, visceral arterial supply was improved.
