[Possibility of serious damage when handling air guns].

The possibilities of serious injury being caused by firearms are well known. Less known is the fact that air guns also have such potential. We present the case of a six year old boy shot in the back with an air gun at a distance of four meters. Vital signs were normal. A small entrance wound was found in the back. On a CT scan, an air gun pellet was found to be situated partly inside the posterior wall of the stomach. There was no sign of peritonitis or complications of any other kind so one chose to await the course of events without surgical intervention. A few days later the patient was discharged in good health. An X-ray taken some days later showed no projectile; it seems to have migrated into the gastrointestinal tract and been shed along with faeces. The available literature suggests that air guns have considerable penetration abilities; this case underlines that. Articles on this subject are summarized and we discuss the options available in similar cases.

[Spontaneous retroperitoneal hemorrhage].

Spontaneous retroperitoneal haemorrhage is most frequently due to rupture of an abdominal aortic aneurysm. Pathology in other retroperitoneal organs, most often the kidney and the adrenal gland, may cause retroperitoneal haemorrhage. Spontaneous rupture of veins, especially the iliac vein, and haemorrhage secondary to anticoagulant therapy, are less common causes. The symptoms are variable and non-specific, but most often include acute abdominal pain, hypotension, peritoneal irritation and a palpable abdominal mass. The diagnosis is confirmed by ultrasonography, computerized tomography, and if relevant angiography or scintigraphy. We discuss three patients with spontaneous retroperitoneal haemorrhage, examine the clinical approach and the role of the various diagnostic aids, and consider how the various conditions should be dealt with.

[Pleuroperitoneal shunt in recurrent pleural effusion].

Recurrent pleural effusion is often a problem in metastases from breast cancer, and may be treated by instillation of irritating drugs combined with external drainage for some days. Less frequently chylothorax is a complication to malignant disease. Drainage of the pleural effusion to the peritoneum is possible, and this article describes how four patients with metastases from breast carcinoma and one patient with chylothorax caused by malignant lymphoma were all treated successfully from 40 days to ten months by means of a simple siliconated T-shaped drain from the pleural cavity to the peritoneum. In one patient the drain occluded after three months. It does not seem to be necessary to use drains with valves for this purpose.

[Thrombolytic treatment of acute arterial thrombosis].

We have treated 14 patients with acute arterial thrombosis with intravenous infusion of streptokinase using a standard dosage scheme. The indication for treatment was critical ischemia due to arterial thrombosis and a presence of symptoms for less than 30 days. The arteriography showed no possibility of reconstructive vascular surgery. The results showed that this treatment is not a good alternative for this group of patients. On the same indications we also treated two patients with intra-arterial infusion of streptokinase at a dosage of 5,000 U per hour. Successful thrombolysis was achieved in both patients. Arteriograms demonstrated that the small distal vessels were opened, along with the femoro-popliteal segment, which showed significant stenosis. The patients could then be helped by reconstructive vascular surgery. We conclude that thrombolysis with intra-arterial infusion of streptokinase is a good choice as the initial treatment for this group of patients. However, the follow-up must include immediate reconstructive vascular surgery or radiological treatment with PTA.

[Regional ischemia/necrosis after surgery of lumbal aortic aneurysm].

Following operation for aneurysm of the abdominal aorta two patients developed buttock necrosis. One procedure was elective and one was an emergency procedure. Patient 1 in addition developed paralysis of the leg on the same side as the buttock necrosis, while patient 2 in addition developed colon ischemia. Both patients died from these complications. Buttock necrosis and paralysis are rare complications after operation for abdominal aortic aneurysm. Regional ischemia of the left colon is a more common complication. The case report illustrates the importance of the pelvic-femoral collaterals. In addition we emphasize the importance of maintaining or restoring hypogastric circulation in order to prevent these complications.
