Ambulatory venous pressure (AVP) and ascending and retro-grade phlebography have been used to elucidate the precise pathogenetic factors in cases of venous stasis. On the bases of this information, procedures aimed at the correction of the particular pathophysiological alterations were carried out. Fifty-two lower extremities in 49 patients suffering from chronic venous statis were studied. ⋯ Three patients had skin sloughing after perforator ligation, and one patient developed a hematoma requiring evacuation following segmental venous transfer. Post-operative AVP evaluation in 11 patients after perforator ligation, two patients following superficial femoral valvuloplasty, one patient after segmental venous transfer, and one patient after cross femoral venous bypass showed significant improvement. Early follow-up results are very satisfactory.

The experience with cerebromeningitis in recipients of 769 renal allografts occurring over a 20-year period has been reviewed. Eighteen patients developed this complication; an incidence of 2.7%. ⋯ The responsible organisms were fungi; the overall mortality rate 44%. By recognizing individual patient types who are at potential high risk for this complication, earlier diagnosis and more prompt and aggressive therapy has diminished the mortality dramatically in the last several years.
