An update of the Zenith endovascular graft for abdominal aortic aneurysms: initial implantation and mid-term follow-up data.

PURPOSE: To evaluate the initial and mid-term results of the Zenith endovascular grafting system for infrarenal abdominal aortic aneurysms. METHODS: Prospective databases at seven centers were used to assess a cohort of patients that underwent treatment for aortic, aortoiliac, or iliac aneurysms since 1995. Data were analyzed to yield descriptive characteristics that pertained to the patients, the aortic morphologic features, the graft configuration, and the complications. Follow-up imaging data were used to determine size changes of the aneurysm sac, endoleak rates, and further complications. Finally survival data were expressed with a Kaplan-Meier analysis. RESULTS: A total of 528 patients were treated with the Zenith endograft. Most of the patients (66%) were considered to be at a high physiologic risk for open repair. Successful graft implantation was accomplished in all but four patients. An overall endoleak rate of 15% was noted, of which 4% was treated urgently because they were thought to represent attachment site faults. The mean follow-up period was 18 months. A total of eight endograft migrations were detected after 2 years of follow-up with an early version of the system. There were three late conversions; two ruptures occurred during the follow-up period. CONCLUSION: This early and mid-term data support the use of the Zenith endovascular graft for the treatment of aortic and aortoiliac aneurysms in properly selected patients. The risks of significant complications or aneurysm rupture are low.

Aneurysm pressure following endovascular exclusion.

OBJECTIVES: To assess the effect of stent-graft implantation on the pressure within an abdominal aortic aneurysm. METHODS: Aneurysm exclusion was performed using an aorto-uniiliac stent-graft in eight patients. Following stent-graft implantation, pressure measurements were performed through a catheter adjacent to the graft in the aneurysm. This "aneurysm pressure" was compared with radial arterial pressure. RESULTS: The pressure was lower in the aneurysm than in the radial artery, in all cases. Mean aneurysm pressure was 36.5/33.8 mmHg, while mean radial arterial pressure was 118.5/50.5 mmHg (p < 0.05, for both systolic and diastolic pressures). These findings corresponded with a reduction in the palpable abdominal pulse, and an absence of perigraft perfusion on follow-up computerised tomography. CONCLUSION: Stent-graft implantation produces a fall in the pressure within an abdominal aortic aneurysm.

[Therapy of an abdominal aortic aneurysm using transfemoral endovascular implantation of a bifurcation prosthesis].

Transfemoral intraluminal placement of a woven-dacron bifurcation prosthesis was undertaken to bridge an infrarenal aortic aneurysm (4.6 cm diameter) in a 65-year-old man with chronic coronary heart disease. The Chuter-Gianturco introducing system was used via the right femoral artery to anchor the prosthesis immediately below the origins of the renal arteries. After fixing the right branch of the prosthesis the left one was secured via the left femoral artery. No leakage was demonstrated on the 7th post-operative day and the aneurysm was satisfactorily bridged. Regular follow-up tests showed a normal circulation. Spiral computed tomography after 18 months confirmed complete thrombosis of the aneurysm.--This case shows that the described method is a promising alternative in the treatment of abdominal aneurysm.

Dynamic respiratory patterns after laparoscopic cholecystectomy.

Important alterations in respiratory function have been observed after open cholecystectomy. These include a decrease in the abdominal tidal volume, forced vital capacity, and forced expiratory volume at 1 s. Laparoscopic cholecystectomy is a new procedure allowing removal of the gallbladder without a subcostal or midline incision. The result is less postoperative pain and earlier ambulation. This study sought to determine whether changes in rib cage and abdominal wall motion are different after laparoscopic than open cholecystectomy. Twelve otherwise healthy patients underwent respiratory inductive plethysmography prior to and one day after laparoscopic cholecystectomy. Frequency of resting breathing increased 29 percent after laparoscopic cholecystectomy (p = 0.03), while abdominal motion decreased 32 percent (p = 0.03). During coached abdominal breathing, rib cage tidal volume increased 70 percent (p = 0.005) and abdominal tidal volume decreased 29 percent (p = 0.01). These alterations in respiratory pattern after laparoscopic cholecystectomy were smaller in magnitude than those reported following the open procedure.

Placement of Hickman-Broviac catheters in the cephalic vein.

By approaching the cephalic vein with an incision placed high in the deltopectoral triangle, instances in which the cephalic vein is absent or too small to cannulate will almost always result in the successful cannulation of an alternative vein located in this region. In those rare instances in which there is no vein which can be cannulated on one side, contralateral dissection is likely to be successful. Occasionally, a catheter will be seen to pass over the clavicle into the external jugular vein. The catheter should be withdrawn and rethreaded because repeat attempts at central placement will usually be successful.

Options for treatment of persistent aneurysm perfusion after endovascular repair.

Persistent aneurysm perfusion represents failure of endovascular repair. The leak may occur around either end of the prosthesis or through a collateral route. Most cases can be treated by endovascular means. Stents can be rotated, the prosthesis can be lengthened at either end, and collateral pathways can be occluded, all without recourse to open repair. This report describes the management of persistent aneurysm perfusion in five patients from a total experience of 32 cases of endovascular aneurysm repair.
