Control of massive hemoptysis by embolization of intercostal arteries.

The embolization of intercostal arteries for the control of massive hemoptysis is described in two patients with bronchopleural fistulas and in one patient with sarcoidosis. Hemoptysis was controlled by embolization in all three cases, but spinal cord infarction occurred in one patient as a result of the procedure. This complication can occur even in cases where no significant blood supply to the spinal cord can be seen on preliminary arteriography, which suggests that in some patients angiographically invisible small branches play an important role in the blood supply to the spinal cord. These branches may be particularly important in cases in which the spinal blood supply is already compromised by surgery, radiation therapy, or previous embolization procedures.

Successful embolization of the dorsal pancreatic artery to control massive upper gastrointestinal hemorrhage.

Selective arterial embolization is an established technique to control gastrointestinal bleeding in patients who are poor surgical risks and in whom bleeding is uncontrolled by other methods. This article describes the control of upper gastrointestinal bleeding by subselective embolization of a bleeding branch of the dorsal pancreatic artery in a patient with severe pancreatitis. This is the first recorded successful embolization of the dorsal pancreatic artery to control hemorrhage.

Embolization for hepatoportal arteriovenous fistula.

The simultaneous occurrence of an intrahepatic hepatoportal fistula and portal hypertension generates questions about the priority and methods of treatment. Catheter embolization of the small-to-moderate fistula is not required, and surgical decompression of portal hypertension is recommended.

Immuno-heterogeneity of the calcitonins of hypercalcemia, breast and lung cancers and medullary carcinoma of thyroid.

Four antisera raised in the goat have very different properties: all recognized the immunoreactive calcitonin (iCT) of medullary carcinoma of the thyroid (MCT), one the response of normal subjects to induced or endogenous hypercalcemia and 2 others a different molecular species which occurs in half the patients with cancer of breast and 3/4 of patients with cancer of the lung. The latter two antisera are most sensitive to the 22-32 sequence of human calcitonin. Depending on the antiserum used, 4 or 7 peaks of immunoreactivity are found in eluates by column chromatography or stimulated serum from MCT. Not all elevated levels of iCT in serum are diagnostic of MCT and ectopic production by lung and breast cancer must be considered. Presence of higher levels of iCT with greater amounts of cancer tissue and undetectable levels after surgery or radiotherapy when using antisera which require intact molecule of calcitonin for recognition suggest the possibility that sequential calcitonin levels with differentiating antisera may be helpful in assessing the extent of disease and response to therapy.

Incarcerated diaphragmatic hernia: report of an unusual case.

Traumatic diaphragmatic hernias, although quite common are frequently overlooked as a cause of intestinal obstruction. The hernia may produce significant symptoms acutely or manifest itself many years following the initial injury. A high index of suspicion is necessary to diagnose intestinal obstruction due to incarcerated diaphragmatic hernia. The operation should be performed through the transabdominal approach when hernia occurs acutely, and the transthoracic approach is recommended when herniorrhaphy is performed long after the time of injury. A case of incarcerated traumatic diaphragmatic hernia that occurred 19 years following a gunshot wound of the chest is reported. The intestinal obstruction was initially thought to be due to cancer of the splenic flexure of the colon.

Crutch-induced axillary artery injury.

PURPOSE: To describe the spectrum of radiologic findings in crutch-induced axillary artery injury and the effects of its unique pathophysiology on diagnostic evaluation and treatment. METHODS: Three patients with axillary crutch-induced axillobrachial injury were studied angiographically and percutaneous intervention was performed in two cases. RESULTS: One patient required surgical bypass of a thrombosed axillary artery aneurysm. One patient responded to percutaneous transluminal angioplasty (PTA) of a focal axillary artery stenosis. One patient with an axillary artery aneurysm and distal thromboembolic disease was treated by both thrombolysis and surgical thromboembolectomy and later by PTA of an axillary artery intimal disruption. CONCLUSION: Chronic axillary crutch use may be associated with axillary artery stenosis, aneurysm formation, and secondary axillobrachial thromboembolic disease. Mural injury can be successfully treated by PTA and thromboembolic disease by thrombolytic therapy. Early identification of the axillary artery lesion is critical for long-term therapeutic results.

Progressive vertebral collapse in diffuse angiomatosis.

A case of vanishing bone disease is presented, with radiologic, endoscopic, and peritoneoscopic evidence of angiomatous involvement of the bones, surrounding soft tissues, and gastrointestinal tract. The diagnosis was made by a combination of radiologic techniques and endoscopy. Areas of absent bone were shown to opacify after intralymphatic injections of contrast material, providing in vivo demonstrations that these areas of vanishing bone are occupied by abnormal lymphatics. The etiology remains obscure, but our review of the literature suggests that this condition may be one of a large spectrum of disorders due to a basic underlying endothelial dysplasia. The lymphatic system, vascular system, or both may be involved, and the condition may manifest itself as an abnormality of the bones, soft tissues, viscera, or a combination of these.

Computed tomographic arteriography as a guide for embolization of widespread hemangioma.

The angiographic work-up of a hemangioma is the most valuable diagnostic modality for the assessment of the extent of tumor and identification of feeding vessels. Occasionally, however, the angiographic findings are inconclusive. It is the purpose of this article to describe a case in which prior to embolization of a widespread subcutaneous and deep hemangioma, computed tomographic arteriography (CTA) was employed to identify the vessel feeding a portion of the tumor which had penetrated the retroperitoneal space causing increasing distress to the patient.

Treatment of thrombosed dialysis access grafts: randomized trial of surgical thrombectomy versus mechanical thrombectomy with the Amplatz device.

PURPOSE: To report the preliminary results in a trial comparing the Amplatz mechanical thrombectomy (MT) device with surgical thrombectomy (ST) to declot occluded dialysis access grafts. PATIENTS AND METHODS: Thirty-seven patients were randomly assigned by computer to either ST (n = 18) or MT (n = 19). Diagnostic fistulograms were obtained at the end of the procedure, and Doppler ultrasound was performed at 1-month follow-up. Plasma free hemoglobin levels were measured before, immediately after, and 24 hours after the procedure in the MT group. Success was defined as initial success with restoration of flow through the graft, primary patency at 30 days, and secondary patency at 30 days. RESULTS: Technical success with MT was 89%. Primary patency in the MT series was 47% and secondary 30-day patency was 68%. Technical success with ST was 83%. Primary patency in the ST series was 77% and secondary patency at 30 days was 77%. Angioplasty (n = 18) and stent placement (n = 6) were performed in the MT cases. Angioplasty was impossible in one patient. Immediately after MT, plasma free hemoglobin levels above normal were noted in 63% of the cases, but these levels were within normal levels after 24 hours in 88% of the cases. CONCLUSION: Initial success of MT in patients with occluded dialysis access grafts is comparable to that of ST. No statistically significant differences in primary or secondary patencies were seen.

Massive pulmonary embolism: preliminary results of treatment with the Amplatz thrombectomy device.

PURPOSE: To determine the feasibility of using the Amplatz thrombectomy device (ATD) to treat massive pulmonary embolism (PE). PATIENTS AND METHODS: Five patients (four men, one woman; mean age, 45.2 years) with massive PE underwent mechanical thrombectomy with the ATD, which creates a vortex that pulverizes and recirculates the clots within the pulmonary circulation. The patients were followed up for 7-18 months after thrombectomy. RESULTS: Marked improvement in pulmonary perfusion was observed in three patients at angiography and ventilation-perfusion scanning. No changes could be assessed in one patient who died shortly after the procedure. One patient developed hemoptysis during the procedure, most likely because of a reperfusion syndrome. A reduction in pulmonary artery pressure was observed in only one patient; the remaining patients had increased pressure. The four surviving patients were discharged within 8 days. CONCLUSION: Mechanical thrombectomy with the ATD provides rapid debulking of thrombus in some patients with massive PE and has the potential to improve treatment and outcomes of the most sick patients.
