PEEP Therapy for Patients With Pleurotomy During Coronary Artery Bypass Grafting

JOURNAL OF CARDIAC SURGERY, Issue 3 2000
Susumu Ishikawa M.D.
We studied the efficacy of intraoperative positive end-expiratory airway pressure (PEEP) therapy for the prevention of postoperative pulmonary oxygenation impairment. A total of 66 patients with solitary CABG procedure were included in this study. The pleural cavity was intraoperatively opened in 44 patients and not opened in 22. PEEP therapy was not used in any patient before May 1996 (referred to herein as the former period) and was used more recently in eight patients with pleurotomy (referred to herein as the latter period). PEEP was initiated immediately after pleurotomy during the harvest of the internal mammary artery graft. Without PEEP therapy, values of PaO2, A-aDO2, and respiratory index (RI) were worse in patients with pleurotomy than in those without pleurotomy. Meanwhile, there were no major differences in these values between patients with or without pleurotomy after the induction of PEEP therapy. Respiratory insufficiency (A-aDO2 > 400 mmHg and RI > 1.5) was detected in six patients with pleurotomy in the former period. Three of these six patients required over 1 week of long-term mechanical respiratory support. No respiratory insufficiency occurred in patients of the latter period. In conclusion, PEEP therapy, which is initiated just after pleurotomy, may prevent oxygen impairment and pulmonary atelectasis after extracorporeal circulation (ECC) and is recommended for patients with pleurotomy, especially for patients with preoperative low respiratory function.

Management of Multivessel Coronary Disease: Let Us Not Shortchange Drug-Eluting Stents

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 3 2008
F.A.C.C., KISHORE J. HARJAI M.D.
A recent observational study of coronary artery graft (CABG) versus drug-eluting stents (DES) performed in the state of New York reported that CABG was superior to DES for multivessel disease. Our comment provides rational criticism of this study, reviews the data that support a role for DES in the management of multivessel coronary disease, and emphasizes the need for ongoing prospective clinical trials in this area. Till randomized trial data become available, physicians should continue to use their clinical judgment based on existing evidence in managing their patients with multivessel coronary artery disease (CAD).

"Backdoor" Alternative Approach to Stenting of a Post-Anastomotic Coronary Artery Lesion via a Chronically Obstructed Right Coronary Artery after Failure to Stent through a Tortuous Free Internal Mammary Graft

JOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 4 2007
RICHARD Y.J. CHAN M.B.Ch.B.
We describe the case of a patient who previously had coronary artery bypass grafting including a free right internal mammary artery graft anastomosed to a chronic totally occluded right coronary artery (RCA) proximally and distally and who presented with a high-risk acute coronary syndrome. Coronary angiography revealed the graft to be patent with a distal post-anastomotic culprit lesion within the posterolateral branch of the native RCA. Because of technical challenges, PCI could not be performed through the graft and the lesion was stented via the chronically occluded RCA instead, in a "backdoor" approach with a good final result.

Cryopreserved iliac artery is indispensable interposition graft material for middle hepatic vein reconstruction of right liver grafts

LIVER TRANSPLANTATION, Issue 6 2005
Shin Hwang
Cryopreserved iliac vein grafts (IVGs) have often been used for reconstruction of middle hepatic vein (MHV) branches in right liver grafts, but their storage pool has often been exhausted in our institution due to the low incidence of deceased donor organ procurement. To overcome this shortage of IVG, we started to use cryopreserved iliac artery graft (IAG). During September and October 2004, we carried out 41 cases of adult living donor liver transplantation, including 29 right lobe grafts with MHV reconstruction. Interposition vessel grafts were autologous vein (n = 6), IVG (n = 13), and IAG (n = 10). IAG was used in 3 (21%) of 13 cases during the first month. For the next month, it was more frequently used (7 [44%] of 16) because handling of cryopreserved IAG was not difficult and its outcome was favorable. On follow-up with computed tomography for 3 months, outflow disturbance occurred in 1 (17%) of 6 autologous vein cases, in 2 (15%) of 13 IVG cases, and in 1 (10%) of 10 IAG cases. Two-month patency rate of IAG was not lower than that of IVG. In conclusion, we feel that cryopreserved IAG can be used as an interposition vessel graft for MHV reconstruction of right liver graft when cryopreserved IVG is not available.

Inside-out vein graft and inside-out artery graft in rat sciatic nerve repair

MICROSURGERY, Issue 1 2003
Alécio Santos Barcelos Ph.D.
Although veins and arteries present similar wall structures, there are differences which may be relevant in peripheral nerve reconstruction. Inside-out vein grafts (IOVG) have been satisfactorily used to repair both motor and sensitive nerves. However, the inside-out artery graft (IOAG) is a new technique and not fully investigated. Our study presents comparative morphological data on nerve regeneration achieved with IOVG and IOAG in the repair of Wistar rat sciatic nerves. Jugular veins and aorta arteries were harvested from donor animals and used "inside-out" to bridge a 10-mm gap. Animals were sacrificed at 10 weeks to evaluate nerve regeneration. Both techniques presented great variability in nervous tissue, though some animals showed satisfactory results. Different intensities of scarring processes might have interfered with nerve regeneration. Although IOVG and IOAG techniques showed similar morphometric results, in general, IOVG presented a closer-to-normal nerve organization than IOAG. © 2003 Wiley-Liss, Inc.
