Chronic upper extremity arterial insufficiency. Etiology, manifestations, and operative management.

Forty-eight arterial reconstructions were performed for chronic upper extremity ischemia in 43 patients, aged 31 to 81 years. Diagnostic arterial catheterization was the most frequent cause of symptomatic occlusion, followed by proximal arteriosclerotic lesions and noniatrogenic trauma. Doppler ultrasound evaluation provided important diagnostic and prognostic data that complemented information derived from arteriography. Indications for operation included disabling claudication (39 cases) or digital gangrene (four cases). Restoration of normal extremity function can be anticipated except in instances where poor forearm runoff exists. Autogenous saphenous and basilic interposition vein grafts have proved excellent for axillary-brachial revascularizations. Axillary-axillary bypass procedures for innominate-subclavian artery occlusions appear hemodynamically sound and technically simple. Follow-up, averaging 48 months, extended to 144 months. Late vein graft failure or progressive distal occlusive disease was not encountered.

Continuing experience with palliative chemical splanchnicectomy.

Forty-one patients underwent open phenol splanchnicectomy for control of pain at the time of initial laparotomy for what was thought to be unresectable pancreatic carcinoma. Twenty-three patients underwent concomitant biliary and/or intestinal bypass procedures. In no patient was laparotomy performed only for the purpose of performing splanchnicectomy. The operative mortality was 15%. In no patient could the addition of splanchnicectomy be implicated as the cause of death. Eighty-eight per cent of patients experienced relief of pain postoperatively. The mean duration of pain control was 4.3 months. The mean postoperative survival was five months. No postoperative complications could be attributed to the addition of splanchnicectomy. Open phenol splanchnicectomy is a highly successful and safe ancillary procedure for control of pain and is recommended at the time of initial laparotomy in patients found to have advanced intra-abdominal neoplasm.

Isolated aneurysms of the iliac artery.

Clinical and diagnostic material were gathered from eight cases of iliac aneurysms encountered over a ten-year period. From the literature, descriptions of 36 lesions were also reviewed to identify their outcome when treated conservatively. Six of the eight aneurysms treated as expected resulted in eventual rupture. Although 48% of all patients (those in the present series and those reported in the literature) had symptoms before rupture, the symptoms of intact iliac aneurysms often mimicked urological or neurological diseases. In contrast to persons with abdominal aortic aneurysms, only 36% of all patients had a palpable abdominal or rectal mass before rupture. In 65% of all cases, noninvasive roentgenography failed to show the lesions. An aneurysmal lesion was often (23%) present in the opposite iliac system as well. Ninety-three percent of all patients survived after an elective operation, but only 48% survived after an emergency iliac aneurysmectomy after rupture occurred.

Femoropopliteal bypass for limb salvage.

A total of 148 femoropopliteal bypass procedures followed for a minimum of 2 years yielded a patency rate of 61.9 percent among survivors. Diabetes mellitus, cigarette smoking, quality of the outflow, or prior inflow procedures did not influence patency rate. Results were less satisfactory in women and when cloth grafts were used. The indications for femoropopliteal bypass require continuing careful assessment.

Influence of operating room surface contamination on surgical wounds: a prospective study.

The influence of operating room contamination on wound infection rates in clean, clean-contaminated, contaminated, and septid procedures was studied by a prospective randomized study of 2,020 surgical wounds. Operating room surface contamination was assessed by the RODAC bacterial plate method. Control rooms uniformly received Wet-Vac cleaning between operations. Experimental rooms were not cleaned between consecutive clean operations, but were cleaned after contaminated operations. The difference in surface contamination between groups of experimental and control rooms was found to be significant at the P less than .05 level. Patients operated on in experimental and control rooms were followed up postoperatively to assess whether they experienced wound infection. No statistically significant differences in wound infection rates were found between experimental and control room operations as total groups, clean procedures, or operations of long duration.
