In situ saphenous vein bypass grafts: angiographic evaluation and interventional repair of complications

In situ saphenous vein grafts are being used with increasing frequency for bypass procedures involving the femoral and popliteal arteries. Complications of these procedures include anastomotic stenoses and persistent arteriovenous fistulae that may result in failure of the graft. Balloon angioplasty and embolotherapy with detachable balloons were employed successfully in three or four recent cases of patients with complications from in situ grafts. Tailored angiography is essential for evaluating in situ grafts, and interventional techniques are extremely useful for managing complications.     

PERINEAL PROCTECTOMY FOR RECTAL PROLAPSE IN ELDERLY AND DEBILITATED PATIENTS

This paper details the indications, operative technique and results of perineal proctectomy in the management of complete rectal prolapse in a high risk, elderly and debilitated group of patients. Eighteen procedures were performed by one surgeon (A.L.P.) on 16 consecutive patients over a 5 year period. Data collection was via: (i) retrospective analysis of hospital and office records; and (ii) response to a postal questionnaire by the patient, a relative or attending nursing staff. There were 14 females and two males with a mean age of 81 years. All patients had significant associated medical conditions. The interval from the time of a surgical procedure until review varied from 3 to 37 months with a mean follow-up period of 16 months. Total hospital stay varied between 6 and 20 days with a mean of 7 days. Eleven procedures were performed under general anaesthesia and seven under spinal anaesthesia. There was no postoperative mortality. One patient suffered an anastomotic haemorrhage that required operative intervention and another patient suffered a rectal stricture that necessitated dilatation. Two patients were re-operated for recurrent symptomatic prolapse at 34 and 36 months after the initial procedure. Continence improved in seven patients, worsened in one and was unchanged in the remaining patients. Fifteen of 16 patients were considered to have had a successful result from the operation with satisfactory control of the symptom of rectal prolapse. Perineal proctectomy is a low risk operative procedure for the elderly and debilitated group of patients in controlling complete rectal prolapse. If the condition recurs, the procedure can be repeated with equally low morbidity.
