Descending thoracic aorta to femoral artery bypass has been used as a remedial operation after aortic or axillofemoral graft failure or graft infection and other intra-abdominal pathologies not amenable to standard aortofemoral revascularization. It can avoid abdomen approach and has been known as a durable procedure with excellent long-term patency. We reported descending thoracic aorta to femoral artery bypass grafting for primary revascularization in a 55-year-old male with hostile abdominal conditions.

We experienced a case of tuberculosis presented simultaneously with pseudoaneurysm of the aorta and ARDS. A 63-year-old man was admitted with complaints of fever and right upper quadrant abdominal pain for a week. Chest X-ray on admission showed a normal finding. Sub-diaphragmatic abscess on abdomen CT scan was suspected and serosanguinous fluid was aspirated from the abscess pocket. On day 2, he was getting more dyspneic and chest X-ray revealed extensive bilateral infiltration. Aspirated fluid revealed AFB. Later, follow-up abdomen CT scan revealed a leakage of dye from the aneurysmal sac of the descending aorta which was previously diagnosed as sub-diaphragmatic abscess. An aortic stent was placed, covering the opening into the aneurysm. The sputum also showed positive AFB. The patient was successfully weaned from the ventilator, and discharged with anti-tuberculous medication on day 42. Follow-up abdomen CT scan 6 months later showed that the aneurymal sac was completely disappeared.

The incidence of abdominal aortic aneurysm is very rare in this country as other disease of the aorta. Aneurysm can be cased by a variable cause but mainly by arteriosclerosis. It is the disease of aged and degeneration. So recently it may be prevalent due to increase of aged people. In general the natural course of an abdominal aortic aneurysm is very grave so surgical intervention is indicated as soon as possible after the diagnosis. Recently a case of abdominal aortic aneurysm was seen in this clinic with abdominal pain and pulsating mass on the abdomen. This case was confirmed by aortography and treated by graft replacement of the aneurysm with favorable result.

Stab wounds, particularly those affecting multiple body regions, present considerable challenges in trauma care. This report describes a case of sustained self-inflicted stab injuries to the abdomen and thighs of a 23-year-old male patient. Although the patient's vital signs were stable and bleeding was minimal from thigh wounds without overt signs of vascular injury, the patient experienced a sudden, profound hemorrhage from the right thigh, leading to cardiac arrest. Successful resuscitation was followed by surgical repair of a right superficial femoral arterial injury accompanying a resuscitative endovascular balloon of the aorta. Subsequent lower extremity computed tomography angiography revealed no additional vascular abnormalities. The patient was discharged in stable condition on the 12th postoperative day. This case underscores the unpredictability of stab wound trajectories and the potential for hidden vascular injuries, even in the absence of immediate life-threatening signs. It also emphasizes the critical role of advanced imaging modalities, such as computed tomography angiography, in identifying concealed injuries, and the importance of strategic intraoperative techniques, including resuscitative endovascular balloon occlusion of the aorta, in achieving favorable patient outcomes.

Aortic dissection is a serious disease that mortality does not approach to zero despite of medical and surgical improvement. Recently two cases of aortic dissection were treated with good results by the two other methods. Case 1 [57-Y-0-Male]; Chief complaint was chest pain radiating to the back. Preoperatively he was controlled by Minipress, dichlotride, & sodium nitroprusside. Aortography showed DeBakey Type III aortic dissection extending from just below the Lt. subclavian artery to the proximal portion of the origin of the renal artery. Through the midline long incision Flow reversal & Thrombo-exclusion method was used, and bypass course was proximal anastomosis at the ascending aorta - through the Rt. thoracic cavity - midportion of the diaphragm - posterior to the liver, stomach, & pancreas - distal anastomosis at the abdominal aorta proximal to its bifurcation. Bypass graft was preclotted 20 mm Dacron Woven Graft, and the aortic arch between the Lt. subclavian artery & Lt. common carotid artery was divided and meticulously sutured. Control aortogram which was done at 4th postoperative month revealed obstruction of the false lumen by thrombosis, and complications were not noticed. Case 2 [53-Y-0-Male]; Chief complaint was chest pain radiating to the abdomen. DeBakey Type III aortic dissection which was similar to the case 1 was detected by the aortography, and involvement of the Lt. subclavian & common carotid arteries was suspicious. Through the Lt. posterolateral thoracotomy the Ringed Intraluminal Sutureless Graft, No. 22 mm, was inserted from just below the Lt. common carotid artery to the midportion of the descending thoracic aorta under total circulation arrest using a F-F bypass, and the Lt. subclavian artery was ligated. Postoperatively hospital course was uneventful with antihypertensive drugs, and any specific complications were not noticed.

Objective: To evaluate the image quality and lesion detectability of lower-dose CT (LDCT) of the abdomen and pelvis obtained using a deep learning image reconstruction (DLIR) algorithm compared with those of standard-dose CT (SDCT) images. Materials and Methods: This retrospective study included 123 patients (mean age ± standard deviation, 63 ± 11 years; male:female, 70:53) who underwent contrast-enhanced abdominopelvic LDCT between May and August 2020 and had prior SDCT obtained using the same CT scanner within a year. LDCT images were reconstructed with hybrid iterative reconstruction (h-IR) and DLIR at medium and high strengths (DLIR-M and DLIR-H), while SDCT images were reconstructed with h-IR. For quantitative image quality analysis, image noise, signal-to-noise ratio, and contrast-to-noise ratio were measured in the liver, muscle, and aorta. Among the three different LDCT reconstruction algorithms, the one showing the smallest difference in quantitative parameters from those of SDCT images was selected for qualitative image quality analysis and lesion detectability evaluation. For qualitative analysis, overall image quality, image noise, image sharpness, image texture, and lesion conspicuity were graded using a 5-point scale by two radiologists. Observer performance in focal liver lesion detection was evaluated by comparing the jackknife free-response receiver operating characteristic figures-of-merit (FOM). Results: LDCT (35.1% dose reduction compared with SDCT) images obtained using DLIR-M showed similar quantitative measures to those of SDCT with h-IR images. All qualitative parameters of LDCT with DLIR-M images but image texture were similar to or significantly better than those of SDCT with h-IR images. The lesion detectability on LDCT with DLIR-M images was not significantly different from that of SDCT with h-IR images (reader-averaged FOM, 0.887 vs. 0.874, respectively; p = 0.581). Conclusion: Overall image quality and detectability of focal liver lesions is preserved in contrast-enhanced abdominopelvic LDCT obtained with DLIR-M relative to those in SDCT with h-IR.

Purpose: Traumatic aortic injuries are rare, but life threatening condition. They usually occur after high velocity impact on the chest or abdomen such as traffic accident or fall. We report the experiences of the traumatic aortic injuries at a single center. Methods: We retrospectively reviewed the medical records of nine patients with aortic injury resulting from the blunt trauma from Jan. 2010 to May. 2016. Results: The mean age was $51.1{\pm}20.8$ years old, and ten (90.9%) were men. The mechanisms of injury were traffic accidents in seven patients (motorcycle accidents; 3, car accidents; 4), and four in fall injury. Most common injured sites were thoracic aorta (9, 81.8%). Aortic injuries were repaired by endovascular approach in four patients, and by open graft surgery in four. Two patients were managed conservatively. Nine patients survived without any complications. Conclusion: We had experienced different approaches for management of aortic injuries after blunt trauma according to locations and severity of lesions.

We examined clinical and reseach data about abdominal palpation conducted in japanese oriental medicine from the early stages of its medical history to the latest research, so as to introduce it into korean oriental medicine. That is to say, we studied clinical significance and suitable oriental medicine prescription about following : sweat and moistness of abdominal skin ; temperature of abdominal skin ; palpation and visible peristaltic movement ; meteorism ; tonus of the whole rectus abdominis muscle ; local tonus of parts rectus abdominis muscle ; palpitation of abdominal aorta ; resistance tender on pressure in epigastric region, subcostal region, umbilical region, lower abdomen, para-umbilical region, cecal region, sigmoid region and inguinal region ; sound of fluctuating liquid in the epigastric region. The result was that abdominal palpation was an immediately applicable method of clinical diagnosis in oriental medicine, and is being proven by western medicine methodology today. Therefore we suggest that korean oriental medicine would advance greatly if abdominal palpation were applied.

The purpose of this study is finding optimum contrast medium quantity during abdominal CT using dual energy technique. The study subjects are 30 patients who had received general single energy abdominal CT and received double energy technique follow-up abdominal CT. dual energy technique abdominal CT images were obtained after setting contrast medium quantities at 30%, 40%, 50%, 60% and 70% of contrast medium quantity at the time of single energy technique. Then the contrast enhancement (Hounsfield Unit; HU) was estimated by setting-up the regions of interest at aorta, inferior vena cava, hepatic portal vein and hepatic parenchymal. The obtained values were compared to the values of the same parts measured during single energy technique abdominal CT. The results of the study were as following. The 60% set up group had HU in aorta : $210.80{\pm}13.609$, IVC : $190.40{\pm}25.215$, hepatic portal vein : $198.40{\pm}21.232$ and hepatic parenchymal : $119.20{\pm}7.98$, The single energy abdomianl CT images had HU in aorta : $205.40{\pm}16.426$, IVC : $188.20{\pm}21.476$, hepatic portal vein : $195.40{\pm}22.744$ and hepatic parenchymal : $121.00{\pm}6.595$. Therefore, it is possible to obtain contrast enhancement by dual energy technique abdominal CT similar to the same by single energy technique abdominal CT by setting-up the quantity of contrast medium at 60% of contrast medium at the time of single energy technique abdominal CT. Based on the result of this study, it is possible to decrease existing quantity of contrast medium by _% and the injection velocity can be also decreased. Accordingly, it is believed that the result of study would be quite useful for patients who have renal function disorder, weak vein or side effect of contrast medium in the past.
