Time and cause of death for 301 patients operated on for abdominal aortic aneurysms.

Time and cause of death were studied in 301 patients operated on for an abdominal aortic aneurysm (AA). The hospital mortality rate was 4% for electively operated patients, 19% for patients with impending rupture, and 58% for those with a ruptured aneurysm. The one- and five-year survival rates were 94% and 68% for the elective group, 70% and 44% for those with impending rupture, and 41% and 31% for patients with a ruptured aneurysm. Of all inpatient deaths, 20% were caused by multi-organ failure. Cardiovascular deaths accounted for 71% of all deaths in patients with AA. 'Sudden death' (cause not known) occurred in 6.6% of all deaths, and in 18% of the late deaths. Although survival probabilities for patients operated on for AA are good if the patients survive the operation and the immediate postoperative period, we found that the majority of deaths were caused by cardiovascular diseases.

Combined scintigraphy of liver, spleen, and lung in the diagnosis of subphrenic abscess.

Two hundred and fifty-six patients have, during the past 5 years, been examined by combined liver, spleen, and lung radionuclide imaging. The reason for this investigation was to identify or rule out subphrenic abscess, which is a rare but feared complication of abdominal surgery. Primary subphrenic abscess may also be seen, and in such cases the diagnosis is extremely difficult. Subphrenic abscess was demonstrated by radionuclide imaging in 17 patients, and all of these were later confirmed by surgery. In this study there was one false-positive and one false-negative result. During this period other pathological conditions involving lung and liver and with symptoms similar to subphrenic abscess have also been demonstrated by this technique, such as lung embolism and liver abscess.

Abdominal aortic aneurysms: survival analysis of four hundred thirty-four patients.

Cases of 434 patients who underwent surgery for abdominal aortic aneurysms in five surgical departments in Norway have been studied with respect to survival patterns and survival probabilities. Of these, 200 patients (median age 63 years) had elective surgery, 173 patients (median age 69 years) had ruptured aneurysms, and 61 patients (median age 67 years) had impending rupture (i.e., emergency operations were performed, but no rupture was found). The hospital mortality rates in the groups were 3.5%, 59%, and 24.6%, respectively. The general probabilities of survival of these groups have been compared with those of a demographically similar population (standard population). Patients who had elective surgery had a slightly, but significantly, lower survival probabilities than did the standard population, whereas the patients who underwent emergency surgery and who survived the first postoperative month showed no increased risk of dying as compared with the standard population. For the elective surgery group, age had a significant effect on survival, whereas the period of operation did not. In the group with ruptured aneurysms both the age of the patient and the period of operation had significant effects on survival, whereas no such effects were found for patients with impending rupture. The survival probabilities for patients surviving the operation were generally good, with a high 5-year survival rate. The mortality rate for patients with ruptured aneurysms decreased significantly from period I (surgery performed before 1976) to period II (surgery performed in 1976 or later). The survival probabilities for patients of advanced age were relatively good, even for patients who had emergency surgery.

Umbilical vein grafts and PTFE grafts for femoro-popliteal bypass. Preliminary results.

This retrospective, multiple-center study includes 172 PTFE (Gore-Tex) and 35 umbilical vein grafts (Bio-graft) used for femoro-popliteal bypass grafting. The one-year patency rate was approximately 63% in both groups. Until further experience is accumulated, autogenous saphenous vein should probably be the first choice for femoro-popliteal bypass grafting. Prosthetic grafts should preferably be used when the saphenous vein is absent or insufficient.

Radionuclide imaging in the diagnosis of liver trauma.

Thirty-three consecutive patients were examined on the clinical suspicion of traumatic rupture of the liver. In 13 patients liver rupture or liver haematoma was found on scintigraphy. In 5 of these patients the scintigraphic observation was verified by surgery. In two of these patients rupture of the spleen was suspected by the clinician, but rupture of the liver was found instead.

Subphrenic abscess.

A series of 39 patients with subphrenic abscess is presented. Nine of the patients had primary abscesses. In 27 patients, the abscess occurred postoperatively, after various abdominal operations, most frequently after gall bladder and gastric surgery. The value of combined lung-liver scintigraphy is stressed, as is promptly established and adequate drainage, using a selective surgical approach. There were 4 deaths in the series.

Management of trauma to the parenchymatous organs.

The incidence of abdominal trauma is increasing, and is related to both increased violence in the society and to the increased frequency of road traffic accidents. Injuries to the liver, pancreas with duodenum, and kidneys are almost always associated with other lesions, and we see the multi-traumatized patient. Splenic injuries however, may be solitary. Since the duodenum and pancreas lie in the depth of the abdominal cavity, they are to some extent surrounded and cushioned against impact by the overhanging liver, the lower lateral and posterior rib cage and the vertebral column. The spleen, on the other hand, is attached to its vascular pedicle, but very mobile and susceptible of injuries involving deceleration and direct blunt trauma.
