Only a small subset of patients with combined superficial femoral artery and vein injuries results in amputation. The importance of the venous component as a risk factor for amputation is uncertain. Ligation vs. reconstruction of venous injuries is controversial. ⋯ All three amputations underwent ligation of the superficial femoral vein with arterial reconstruction by placement of a reversed interposition saphenous vein graft (p = 0.0009). None of the remaining 22 patients with salvaged limbs underwent reconstruction by this combination of techniques. Consequently, the authors emphasize the importance of venous reconstruction, particularly in combined injuries with major arterial involvement requiring interposed grafts.

Severe pancreatic complications following cardiac surgery are rare, but 14 patients with severe pancreatitis have been encountered since 1971. Six of these developed acute fulminating pancreatitis following cardiac surgery and each of these died within 21 days following operation. Seven patients had less severe pancreatitis, resulting in pancreatic abscess formation and five in this group expired. ⋯ Although the etiologic mechanisms are unclear, possible factors include: prolonged cardiopulmonary bypass, "the low cardiac output syndrome," and inadequately treated or unrecognized postoperative pancreatitis. The diagnosis is based on physical examination, upper gastrointestinal series, and the abdominal CT scan. Despite aggressive surgical therapy, pancreatitis following cardiopulmonary bypass is an extremely serious condition.
