Hemoperitoneum due to spontaneous rupture of an aneurysm of the left gastroepiploic artery.

We report the case of a woman, age 65 years, who was admitted to our hospital for intense abdominal pain. Hemoglobin was 9.7 g/100 ml and computed tomography (CT) confirmed the hemorrhagic state showing intraperitoneal blood. After laparotomy a ruptured aneurysm of the left gastroepiploic artery was diagnosed. Ligation of the artery was performed with good results. This case is reported because the situs of this aneurysm is very rare.

Repair of femoral pseudoaneurysm after cardiac catheterization: utility of extraperitoneal iliac control.

Femoral artery lesions may occur after cardiac catheterization or percutaneous transluminal coronary angioplasty (PTCA). The incidence of pseudoaneurysm following transfemoral catheterization ranges from 0.21 to 6.25%. Among 3162 cardiac catheterization procedures thirteen (0.41%) patients presented a femoral pseudoaneurysm requiring surgical repair. The Authors reported their technical consideration about the utility of extraperitoneal iliac control during surgical repair of femoral artery pseudoaneurysm due to cardiac catheterization.

[The predictiveness of the duplex scan method in monitoring a venous femoro-distal bypass].

The medium-term failure of femoro-distal revascularization using venous bypass is often preceded by the onset of intrinsic intraprosthetic lesions which, if not diagnosed, may develop and cause thrombosis in the venous prosthesis. The authors report their experience relating to the monitoring of these bypass operations using an echo-Doppler test which was found to be a sensitive and reliable method. In their opinion, frequent instrumental control may significantly reduce the number of occlusions in the venous prosthesis if a rapid surgical therapeutic approach is adopted towards those intraluminal lesions considered to represent a risk.

Digital celiac arteriography.

Sixty patients underwent intraarterial DSA with injection into the celiac artery for evaluation of various hepatic, pancreatic, and splenic lesions. Twenty of these patients also underwent conventional arteriography for comparison. Excellent images during the early arterial phase (free of bone superimposition and artifacts) were obtained with DSA. The late arterial and parenchymal phases of the examination were less definitive when compared with conventional angiography. The venous phases of the liver studies were good and compared favorably in contrast and resolution to conventional methods. In the late venous phase, good images of the portal system were obtained using a small amount of contrast medium. Respiratory movements and artifacts were overcome with postprocessing. Most of the studies were performed using the 12-inch mode of the image intensifier, which represents the best choice between the size of the field examined and the spatial resolution of the system. We believe that DSA is a suitable substitute for conventional angiography in most patients in whom celiac trunk angiography would be used.

CT of functioning tumors of the pancreas.

Thirty-three patients suspected of having a functioning tumor of the pancreas were studied with computed tomography (CT); 25 had angiographic studies also. Thirty-one cases were confirmed surgically; the other two were lost at follow-up and were excluded from the series. Of the 31 patients, 21 had insulinomas, five had Zollinger-Ellison syndrome, and five had assorted apudomas. CT was positive in 71% of the cases and negative in 29%; 22.6% of the studies were false negative and 6.4% were true negative. There were no false positives. Of the 21 patients with insulinomas, only one had false-negative CT and angiographic studies, caused by diffuse microadenomatosis. In one patient, two separate lesions of the pancreas were seen and identified correctly on both CT and angiography. All identified lesions smaller than 2 cm were seen only because of a hyperdensity on the enhanced CT scan. Lesions larger than 2 cm were identified either because their size distorted the pancreatic contour or because of their vascularity. The importance of proper CT technique using fast scanners and repeated bolus injections of contrast medium is stressed.

Digital subtraction angiography for examination of vessels of the leg: use of a 40-cm image intensifier.

Digital subtraction angiography (DSA) using a 41-cm (16-in.) image intensifier was performed in 144 patients with peripheral vascular insufficiency. In most cases the entire peripheral vascular bed from the renal arteries to the popliteal trifurcation was demonstrated with four intravenous injections and four exposed fields: (a) aorto-iliac, (b) ilio-femoral, (c) femoro-popliteal, and (d) popliteo-tibial. In 90% of cases the procedure was diagnostic in all regions studied, while in 10 it was nondiagnostic in one or more regions for various reasons (myocardial insufficiency, inadequate contrast bolus, or technical failure). Most failures involved the distal arteries. In spite of some limitations, intravenous DSA using a large-field image intensifier may replace conventional angiography in routine preoperative evaluation of peripheral vascular disease, with intra-arterial injections being performed when the intravenous technique is nondiagnostic.

[Angiography in the evaluation of injuries of the peripheral arteries].

The authors present the results achieved with angiographic evaluation of 34 patients suffering from extremity injuries. In spite of the improvements of various diagnostic techniques, especially ultrasound studies, they believe that emergency arteriography is the only way to obtain an ultimate answer in vascular traumas caused by extremity injuries.
