BACKGROUND: Chronic dissection of the thoracic and thoracoabdominal aorta as sequela of a prior type A or B dissection is a challenging problem that requires close radiographic surveillance and prompt operative intervention in the presence of symptoms or aneurysm formation. Open repair of chronic thoracic and thoracoabdominal aortic dissection using deep hypothermia has been our preferred method to treat this complex pathology. The advantages of this technique include organ and spinal cord protection, the flexibility to extend the repair proximally into the arch, and the ability to limit ischemia to all vascular beds...

PURPOSE: To investigate the blood supply to the nipple areola complex (NAC) on thoracic CT angiograms (CTA) to improve breast pedicle design in reduction mammoplasty. METHODS: In a single centre, CT scans of the thorax were retrospectively reviewed for suitability by a cardiothoracic radiologist. Suitable scans had one or both breasts visible in extended fields, with contrast enhancement of breast vasculature in a female patient. The arterial sources, intercostal space perforated, glandular/subcutaneous course, vessel entry point, and the presence of periareolar anastomoses were recorded for the NAC of each breast...

Deep sternal wound infection is a severe complication after open heart surgery. According to the different severity and dimensions of the deep sternal wound infection, the treatment method is different. In this study, we aimed to describe our experience with the rectus abdominis myocutaneous flap for large sternal wound management, especially when 1 or 2 internal mammary arteries were absent.Between October 2010 and January 2016, a retrospective review of 9 patients who suffered from the extensive thoracic defects after deep sternal wound infection was conducted...

Anatomical variation of the branching pattern of axillary artery is very common. The knowledge of this variation is often useful during different surgical and interventional procedures. Variations include typically of Lateral Thoracic Artery (LTA) and Posterior Circumflex Humeral Artery (PCHA). The present case has been reported to document the variation of LTA and PCHA. The axilla of a 65-year-old embalmed female cadaver was routinely dissected for educational purpose in the Department of Anatomy, AIIMS, New Delhi, India...

BACKGROUND: Although the use of lateral intercostal artery perforator (ICAP) flaps for immediate breast reconstruction has been widely described, data on the use of the anterior ICAP (AICAP) flaps for this indication are limited. In this context, we describe the results of anatomical study and our clinical experience with AICAP flaps for breast reconstruction. METHODS: In this study, the location and characteristics of the AICAPs were dissected in 12 female adult formalin-preserved hemitrunks and two fresh-frozen cadavers...

Minimally invasive transverse aortic constriction (MTAC) is a more desirable method for the constriction of the transverse aorta in mice than standard open-chest transverse aortic constriction (TAC). Although transverse aortic constriction is a highly functional method for the induction of high pressure in the left ventricle, it is a more difficult and lengthy procedure due to its use of artificial ventilation with tracheal intubation. TAC is oftentimes also less survivable, as the newer method, MTAC, neither requires the cutting of the ribs and intercostal muscles nor tracheal intubation with a ventilation setup...

BACKGROUND: Medical treatment of initially uncomplicated acute Stanford type-B aortic dissection is associated with a high rate of late adverse events. Identification of individuals who potentially benefit from preventive endografting is highly desirable. METHODS AND RESULTS: The association of computed tomography imaging features with late adverse events was retrospectively assessed in 83 patients with acute uncomplicated Stanford type-B aortic dissection, followed over a median of 850 (interquartile range 247-1824) days...

We present a case report of recurrent disseminated peritoneal leiomyomatosis in a 30-year-old female with a past history of laparoscopic myomectomy by a technique of morcellation for a large fibroid in 2014. After one year she presented in 2015 with a well-defined oval shaped fibroid along the anterior abdominal wall, which was supplied by the 10th intercostal artery and a branch of right internal mammary artery. She was again presented after 1 year in 2016 with a large pelvic-abdominal fibroid with blood supply from the omental artery, a branch from the right gastroepiploic artery, and sigmoid branches of inferior mesenteric artery...

Perforator flaps have become very popular in reconstructive surgery. The thoracodorsal and lateral thoracic artery perforator flaps are highly studied, and successful clinical series have been reported, whereas the literature concerning the lateral intercostal and serratus anterior artery perforator flaps is quite poor and their vascular anatomy needs yet to be clarified. We describe a case of free serratus anterior artery perforator flap for the reconstruction of a dorsal defect of the foot, followed by an anatomic and radiological study...

Our discovery of a case of persistent double dorsal aorta prompted us to systematically review the literature of all previously reported cases of this anomaly. For our case, we present a completely separated double dorsal aorta, with the right accessory aorta arising from the abdominal aorta and ascending through the aortic hiatus to supply posterior intercostal arteries (PIAs) to the 9th-3rd spaces bilaterally. We examined and compiled data from the 10 previously reported cases, along with our observations from our cadaver, into a systematic review of all known cases of persistent double dorsal aorta...

Luca Di Marco, Antonio Pantaleo, Alessandro Leone, Giacomo Murana, Roberto Di Bartolomeo, Davide Pacini
Complex lesions of the thoracic aorta are traditionally treated in 2 surgical steps with the elephant trunk technique. A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis. These are very complex and time-consuming operations, and good results can be obtained only if appropriate strategies for myocardial, cerebral, and visceral protection are adopted...

A 10-year-old dog weighing 3.4 kg presented with intermittent regurgitation. Esophagography revealed that the thoracic esophagus was compressed dorsally at the region of the fourth intercostal space and segmentally dilated from the second to third intercostal region. Three-dimensional computed tomographic (CT) angiography confirmed a suspected vascular ring anomaly and also revealed multiple other vascular anomalies. These included aberrant right subclavian artery, absence of bilateral external jugular veins, right-gastric caval shunt, and a completely duplicated caudal vena cava...

Santiago Rojas, Eduard Quintana, Marisa Ortega, Alfonso Rodríguez-Baeza
Bronchial arteries commonly originate from thoracic aorta between T5 and T6. Ectopic origins from aortic arch, supraortic trunks and their branches, coronary arteries, and even abdominal aorta have been described in the literature. In some circumstances, such as pulmonary artery malformations, chronic embolism, or inflammatory diseases of the lung, the bronchial arteries become hypertrophied and eventually could be the only supply of pulmonary circulation. Here, we describe a case of an elderly man who presented an unusual pattern of bronchial arteries of the right lung combined with severe bilateral hypertrophy of bronchial vessels...

Sex and ovarian cycle have been speculated to modify respiratory muscle(s) blood flow control during exercise, but the findings are inconclusive. We tested the hypotheses that females would have higher respiratory muscle blood flow and vascular conductance (VC) compared to males during exercise and that this difference would be accentuated in proestrus versus ovariectomized (OVA) females. Mean arterial pressure (carotid artery catheter) and respiratory muscle blood flow (radiolabeled microspheres) were measured during moderate-intensity (24m/min, 10% grade) exercise in male (n=9), female (n=9), and OVA female (n=7) rats and near-maximal (60m/min, 5% grade) exercise in male (n=5) and female (n=7) rats...

BACKGROUND: Selection of suitable perforators is critical for satisfactory postreconstructive surgery outcome. This study aims to compare a small central versus a large peripheral perforator flap in a rat extended dorsal three-vascular territory perforator flap model. METHODS: An extended intercostal artery perforator flap with three vascular territories was used to model a small central perforator flap. An extended deep circumflex iliac artery flap with three vascular territories was used to model a large peripheral perforator flap...
