2 Liver specimens showing the fundus of the Gall bladder lying within the inferior surface of the liver (not able to reach the inferior border)

Inferior surface of Liver

The images above show the Gall bladder lying out of the inferior surface of liver and extending much beyond the inferior border.
The gall bladder fossa is covered by peritoneum.

Last 4 images

Gall bladder is lifted up along its body, fundus and cystic duct in different directions showing that it is not lying in its fossa

the galbladder is lifted up to the extereme left side of the liver.the fundus ,body and cystic duct were all being lifted upfrom the inferior surface.s

the galbladder is fully lifted up from the inferior surface,the peritoneum is seen covering the entire gal bladder fossa.

the fundus of the galbladder is not reaching(falling short of) the inferior border of the liver

Accessory renal artery

2012-04-24T15:29:00.001+05:30

Left kidney with twin accessory renal arteries

During the routine dissection hours a cadaver displayed a left kidney supplied by two accessory renal arteries which branched out from the aorta and had a sinuous course. The main renal artery (MRA) was seen entering into the hilum behind the main renal vein(MRV) .

The first accessory renal artery(ARA-1) branched from the left lateral side of the aorta just above the level of superior mesenteric artery.

It was running laterally showing a kink almost in the centre of its course. It entered into the kidney through the anterior substance of the kidney just above the hilum.

A segmental branch was seen entering the hilum lying anterior to the main renal vein.

The 2^nd accessory renal artery(ARA-2) was seen arising about 5.7 cms below the origin of superior mesenteric artery(SMA) . It is longer than the 1^st accessory renal artery extending laterally from the aorta it is seen entering into the left kidney just below the renal pelvis. A gonadal branch was seen branching out . The left gonadal vein( LGV) is seen draining into the left renal vein .

The hilum was extending over to the anterior surface of the kidney and crowding of the vascular structures was seen . However the pelvis remained most posterior .

Clinical significance

Presence of such twin renal arteries can complicate the interpretation of renal angiograms and challenge the urologists performing laparoscopic and renal transplantation procedures

TRILOBED LEFT LUNG DUE TO AN ACCESSORY HORIZONTAL FISSURE

During the dissection, a female cadaver displayed the left lung with two fissures just as the right lung.

Both the right and left lung were having the horizontal and oblique fissures at the same level. The horizontal fissures of the left lung divided the entire lung parenchyma of the upper lobe into two lobes. it was prominently seen on both costal and mediastinal surfaces. During the development as the lung grows, the fissures that seprate budding individual bronco pulmonary segments get obliterated except along two planes which in fully formed lungs persists as horizontal and oblique fissures. The accessory fissure could be the result of non-obliteration of spaces which normally do obliterate. The accessory fissure may be of varying depth occurring between two broncho pulmonary segments. In the present case it was deep. Radiologically an accessory fissure can be mistaken for a lung lesion. Most of the times the accessory fissures act as a barrier to the spread of infection creating as a sharply marginated pneumonia which could be wrongly interpreted as consolidation / atelectasis. Thus challenging the radiologists expertise.

Note:

1. usually the left lung has only one deep oblique fissure, spiral in its course dividing it into two lobes. And upper (superior) lobe forming the apex and the anterior margin of the lung and the lower (inferior ) lobe forming the diaphragmatic major part of the posterior surface.

2. The presence of oblique fissure in a normal scenario enables the uniform the expansion both the upper and lower lobes of the left lung.

3. The fissures act as a reliable land mark in specifying thoracic and particularly pulmonary lesions

Common CAROTID ARTERY WITH “SIPHONHOUS” – S-SHAPED TERMINATION ( WITH DUAL KINKS)

In a male cadaver aged about 60 years the right sided CCA from its origin to the level of cricoid cartilage is uniform in its diameter and showed the same diameter as that of the left side. From the level of cricoid cartilage it has shown a gradual dilatation and showed a kink with the convexity backwards at the level of lower part of thyroid cartilage and another kink with the convexity forwards at the upper margin of the thyroid cartilage at an obtuse angle about 1 cm above the upper margin thyroid cartilage. It bifurcated in to the medial terminal branch – EXTERNAL CAROTID ARTERY (ECA) and lateral terminal branch – INTERNAL CAROTID ARTERY ICA. The ICA rather than passing straightly upwards had a “ C” shaped curved course in its proximal course. The ECA and its branches where seen dilated to lesser extent and were very tortuous in their proximal course and were not according to the description of any standard text book

CLINICAL SIGNIFICANCE:

According to the neuro surgeons the study of common carotid artery with regard to its bifurcation angle (position and branching), tortuosity, vascular geometry vascular aging are of potential importance as they are risk factors for the atheromatous plaque formation.

Note:

1. Generally siphon is used for the intracranial course of ICA by anatomist, radiologist, neurologist and neuro - surgeons

2. The vagus nerve and IJV Internal Juglar Vein are dissected off.

3. Initially the CCA trunk along with its terminal branches was colored RED paint later removed by using a dissolvent. Hence some areas are showing reddish colouration.
