Sternal fracture is relatively common after blunt chest trauma, and this usually resolves without complication. But acute extrapericardial tamponade caused by sternal fracture and injury to the internal mammary artery secondary to blunt chest trauma is very rare. We report here on two cases of acute extrapericardial tamponade that were caused by blunt chest trauma.

5.A Tunnel Technique to Protect the Skeletonized Left Internal Thoracic Artery.
The Korean Journal of Thoracic and Cardiovascular Surgery 1999;32(7):690-692
internal thoracic artery is used in myocardial revascularization because of many advantages. However, it may not be appropriate in the usual extrapleural or intrapleural route, because it can be easily displaced and injured due to the slender and weak characteristics. We introduce here, a simple technique of repositioning the skeletonized left internal thoracic artery in a stable and straight course by creating a tunnel between the left lateral pericardium and thymic tissue.

It is now widely accepted that the complete arterial coronary revascularization has better short and long term results compared to coronary bypass surgery using arterial graft mixed with vein graft mainly due to its superior patency rate. However, sometimes the internal thoracic artery and other conventionally used grafts might be unavailable or it may require caution in using bilateral internal thoracic artery especially in diabetic patient because of the possible risk of the mediastinitis or other associated morbidities. Moreover, there could also be a shortage for arterial graft in case of coronary reoperation. We report our first three cases using thoracodorsal artery(TDA) as an alternative graft in complete arterial coronary revascularization.

During coronary artery bypass surgery, there are several discrete maneuvers that facilitates localization of the invisible left anterior descending coronary artery. In some cases with intramyocardial left anterior descending artery, long-term patency of a bypassed graft may depend on anastomosing the internal mammary artery graft to the more proximal and superficial site of the intramyocardial left anterior descending artery. We describe an easy technique to locate the proximal superficial left anterior descending artery with a distal coronary arteriotomy and retrograde insertion of a coronary probe.

PURPOSE: As a recipient vessel, internal mammary vessels have many advantages for microvascular reconstruction of the breast. But the approach is time consuming and results in large morbidities. However, the perforating branches of the internal mammary vessels can be used to minimize such demerits. The purpose of this cadaver study is to clarify the location and diameter of the perforating branches of internal mammary vessels and to prove that they are safe and reliable recipient vessels. METHODS: We studied 11 formalin-fixed cadavers and dissected their anterior chests bilaterally. The chests were exposed using midline presternal incisions. We dissected and found all perforators at subfascial planes under loupe magnification. The number, external diameter, and the distance from the midline were measured. Result: The mean external diameter of the arterial perforators was 1.32mm and the mean external diameter of the venous perforators was 1.48mm. The largest arterial and venous perforators were most frequently found in the second intercostal space. The mean distance from the midline to the perforator was evaluated; the artery averaged 1.95cm and the vein averaged 2.08cm. CONCLUSION: This study will be helpful when using the internal mammary perforating vessels as a recipient vessel during breast reconstruction.

Injury to the internal mammary artery secondary to blunt chest trauma is a rare condition. It is also uncommon to see extraplerual and mediastinal hematoma in these circumstances; this demands early diagnosis and active treatment. We report here on a 59 year old man who underwent surgery for extraplerual and mediastinal hematoma, and this was all due to injury of the internal mammary artery after blunt chest trauma. We also include a review of the relevant literature.

BACKGROUND: Hemodynamic derangement during off-pump coronary artery bypass surgery (OPCAB) is mainly attributed to impaired filling and diastolic dysfunction. An elevated ratio of the mitral velocity to the early-diastolic velocity of the mitral annulus (E/e' > 15) is a relatively new indicator of diastolic function, and this was reported to be associated with impaired hemodynamics during OPCAB. We investigated the efficacy of milrinone on the perioperative hemodynamics and short term outcomes of patients with an E/e' > 15 and who underwent OPCAB. METHODS: The patients were randomly allocated into either group C (control, n = 31) or group M (n = 31) and they were treated with the same amount of either normal saline or milrinone (0.5 microg/kg/min) without bolus loading after completion of internal mammary artery harvest until the end of operation. Hemodynamic measurements were recorded after the induction of anesthesia (T1), 5 min after starting each distal anastomosis of the left anterior descending artery (T2), left circumflex artery (T3) and right coronary artery (T4), and 5 min after sternum closure (T5). RESULTS: The mixed venous oxygen saturation (SvO2) was lower through T2-T4 compared to the baseline value in both groups, while the degree of the decrease was significantly less in group M than that in group C. The other hemodynamic variables, the operative data and the postoperative outcomes were similar between the two groups. CONCLUSIONS: Intraoperative infusion of milrinone did not significantly improve the perioperative hemodynamics and the subsequent short term outcomes for the patients with preexisting diastolic dysfunction as represented by an elevated E/e' value, although it reduced the degree of decrease of the SvO2 during OPCAB.
