Question 1. Describe the clinical features, diagnosis, and treatment of thromboangitis obliterans.
Answer:
Thromboangitis Obliterans/Buerger’s Disease:
- Thromboangitis Obliterans is the inflammatory reaction in the arterial wall with the involvement of the neighboring vein and nerve, terminating in thrombosis of the artery.
Thromboangitis Obliterans Clinical Features:

- Pain increases when the muscle is exercised
- Postural color changes appear followed by trophic changes.
- Gradually ulceration and gangrene occur.
- Gangrene starts from one digit and then involves the entire foot.
- BP is normal in the normal limb but reduced in the diseased limb.
Thromboangitis Obliterans Diagnosis:
- Arteriography.
- Large arteries show abrupt areas of occlusion surrounded by extensive collateral circulation.
- It gives a tree roof or ‘spider legs’ in appearance.
- Peripheral arteries give a ‘corkscrew’ appearance.
Thromboangitis Obliterans Treatment:
- Conservative treatment.
- Quit smoking.

Question 7. What are the methods of spread of carcinoma? Describe the block dissection of neck.
Answer:
Methods Of Spread Of Carcinoma:
- Through the lymphatic system.

- Through bloodstream.
- Malignant cells can break off from the tumor and travel through the bloodstream until they find a suitable place to start forming a new tumor.
- Sarcomas spread through the bloodstream.
- Through local invasion.
- Tumors invade the surrounding normal tissue.
- Through implantation or inoculation.
- It occurs rarely.
- Can happen accidentally when a biopsy is done or when cancer surgery is performed.
- Malignant cells actually drip from a needle or an instrument.
Block Dissection Of Neck:
- The main goal of the procedure is to remove the entire ipsilateral lymphatic structures.
Block Dissection Of Neck Procedure:
- Incisions are made.
- Crile’s T incision
- Martin’s double Y incision
- Ward’s Y incision
Two horizontal incisions.
