Noncovered stent placement in a blunt traumatic injury of the right subclavian artery.

We report a case of scapulothoracic dissociation with right subclavian artery traumatic injury that was managed by endovascular treatment. Particular features are the use of a flexible self-expandable noncovered stent and simultaneous protection of the right common carotid artery from distal embolization by inflating a balloon catheter.

A comparison of the efficacy and safety of ioxaglate and iobitridol in renal angioplasty.

PURPOSE: To compare ioxaglate and iobitridol for percutaneous transluminal renal angioplasty (PTRA) as regards thromboembolic complications, the quality of diagnosis, and renal and general safety. METHODS: One hundred and eighty-nine patients were prospectively studied, 98 of whom received ioxaglate, and 91, iobitridol. Twenty-two were secondarily excluded from the evaluation of thromboembolic complications as they did not undergo PTRA. RESULTS: Two hundred and two PTRAs were performed. The total volumes of contrast medium administered and the procedure durations were the same for each patient. In the ioxaglate group, four dissections (3 stents), one occlusive dissection, and two spasms occurred; in the iobitridol group, there were three dissections (all stented), one occlusive dissection (stented), and two spasms. The final angiograms showed four renal infarctions with ioxaglate (2 of which were in patients who were not anticoagulated), two with iobitridol. No significant difference was seen in the incidence of thromboembolic complications when the PTRA was performed after anticoagulation (n = 150; 3.9% vs 4%, p = 0.78); in the whole population, thromboembolic complications were more frequent in the ioxaglate group but the difference was not significant (5.7% vs 3.7%, p = 0.74). The quality of the diagnosis and the general and renal safety were the same in the two groups. CONCLUSION: Regarding the clotting phenomenon, we recorded as many thromboembolic complications with ioxaglate as with iobitridol.

Imaging features of uncommon adrenal masses with histopathologic correlation.

Uncommon adrenal masses include cystic lesions (hydatid cyst, endothelial cyst), solid lesions (hemangioma, ganglioneuroma, angiosarcoma, primary malignant melanoma), and solid fatty lesions (myelolipoma, collision tumor). Most of these lesions do not have specific imaging features. The liquid content of adrenal cysts is clearly demonstrated on ultrasonographic scans, computed tomographic scans, and magnetic resonance images. Nevertheless, the histologic type cannot be predicted except at some stages of hydatid disease in which pathognomonic features are present. The most typical imaging features of hemangioma are phleboliths and enhancement of peripheral vascular lakes. Ganglioneuroma has nonspecific radiologic features, but this diagnosis should be considered in cases with early enhancement of fine septa and progressive filling. The radiologic features of angiosarcoma and primary malignant melanoma are nonspecific. A macroscopic lipid content within an adrenal mass is theoretically characteristic of myelolipoma. This diagnosis should be made with caution, especially when the lipid content is not predominant, because of the possible association with an adenoma.

In vitro evaluation of the embolic risk of diagnostic and therapeutic intravascular procedures.

BACKGROUND: The purpose of the study was to evaluate the risk of distal embolisation in a silicon model during different endovascular diagnostic and therapeutic procedures. MATERIAL AND METHODS: Endovascular technics, such as guidewire and catheter advancement, metal stent placement and balloon angioplasty were compared. Clots were produced from human blood sample. The transparent silicon model was filled with saline, flow was generated by an hydraulic pump. Stenosis was created by mechanical compression. The size of the circulating particles were measured with a mesh of nylon filters. RESULTS: No loose particles were detected using guidewire, pigtail and straight catheters. Balloon inflation induced embolisation of particles ranging from 100 microns to 10 mm in length. Deployment of self expandable metallic stents did not result in particle migration but secondary angioplasty inside the stent detached particles (ranging from 400 microns to 12 mm in length). Deployment of balloon expandable stent yielded in the stretching of the clot, which became sometimes longer than the stent, resulting in the detachment of the non covered portion. CONCLUSION: The risk of distal embolisation during guide-wires and catheters manipulation is not significant. Balloon catheters and secondary angioplasty after deployment of self-expanding stents caused large particles detachment.

[Computed tomographic exploration of eventrations].

With physical examination alone it is difficult or even impossible to evaluate the abdominal wall damage in patients with major evisceration, especially when they are obese. Computerized tomography (CT) is very useful in this respect as it provides a detailed anatomical overview of the lesions. CT was performed in 30 out of 229 patients operated upon. It supplied information on the size, site and extension of eviscerations and showed whether they were single or multiple; it also informed on the quality, thickness and retraction of the abdominal muscles. All this is extremely important to know before surgery as it enables the operative problems to be foreseen and, to some extent, the operative procedure to be determined. In all cases of complex evisceration CT may be regarded as the "key examination".

[Is percutaneous transluminal angioplasty of the femoral and popliteal arteries a justifiable procedure? A discussion in relation to 58 attempts].

Angioplasty of the femoral and popliteal arteries was attempted in 58 cases over a period of 2 years. Ideal cases for treatment by percutaneous transluminal angioplasty (PTA) are those with stenoses less than 3 cm or obliterations less than 6 cm in length where the onset was between 6 months and 2 years previously. Immediate success was obtained in 50 cases (86 patients), failures usually being observed in very advanced cases. Permeability after 2 years, by actuarial calculation, was observed in 85 p. cent of cases and there were 7 complications (12 p. cent) in the 58 patients, one of whom required urgent surgery. This method represents an alternative procedure to conventional surgical shunts in young subjects, those at high surgical risk, and those with lesions in two zones. These results illustrate the value of early diagnosis, by arteriography of the lower limbs, to detect recent lesions responding best to PTA and thus to gain time in the long and painful history of this disease.

[The diagnostic value of radiological examinations in Conn's syndrome: angiographic findings in 58 cases (author's transl)].

Selective adrenal phlebography with measurement of hormone levels was used to investigate the majority of 58 cases of primary hyperaldosteronism. The authors stress the importance of pre-operative diagnosis of the lesion as surgery is indicated for adenomas only, and because of their small size they are often missed in adrenal scintigrams and on manual exploration during operation. They are in agreement with most other authors that adrenal phlebography is the most valid investigation, as it gives a precise diagnosis of the lesion in 92% of cases. The angiographic findings in the most common lesions are described, the difficulty in diagnosing peripheral small adenomas stressed, and the problems associated with the diagnosis of nodular hyperplasias outlined. They also underline the fundamental importance of selective hormone levels measurement, as these results are of equal value to those of the images themselves.

[Pseudotumoral abdominopelvic lipomatosis. Value of the scanographic examination].

The authors report three cases of abdominal lipomatosis, presenting as an abdominal mass. The problems of diagnosis caused by this rare entity are discussed. The value of the CT scan is emphasized. Indeed, only this examination is able to give all the informations necessary for the diagnosis. Ultrasonography seems to be particularly useful in the assessment of the evolution of this disease, especially for the study of the urinary complications. Before apparition of these complications, no treatment is required.
